Repair mssql database

SQL Server errors are not hostages of only the complex operations, but while the normal and usual operations like SELECT and UPDATE are attempted; several error messages may also be seen. The error messages, as mentioned below, indicate that the SQL database is suffering from some sort of inconsistencies, but, at the ultimate resort, can make you feel need of SQL repair. However, there are few assertion error messages, which may indicate inconsistencies in the database, such as:

Msg 3624
Location: recbase.cpp:SQLServerVersion
Expression: m_offBeginVar < m_SizeRec SPID: ProcessID
Process ID: SQLServerEXEProcessID

Msg 3624
Location: p:\sql\ntdbms\storeng\drs\include\record.inl:SQLServerVersion
Expression: m_SizeRec > 0 && m_SizeRec <= MAXDATAROW SPID: ProcessID
Process ID: SQLServerEXEProcessID

Research shows that when the SQL Server application tries to read data from the data page, the mentioned assertions may be observed, during which an error log file is created which records the corresponding information. Now, as there were no clear indicatives about what has caused the error to occur, SQL 2000 Service Pack 4 has changed the scene in which the problematic assertions appeared. Now, these problems come in the form of the following error message:

Error: 7987, Severity: 22, State: 1 A possible database consistency problem has been detected on database ‘<dbname>’. DBCC CHECKDB and DBCC CHECKCATALOG should be run on database ‘<dbname>’.

Thus, as the stated error messages are occurring and some inconsistencies exist in the database, you need to have MDF repair by running the DBCC CHECKDB command and resolving the reported issues. However, if you come at the stage, when removal of errors is being hard and you have no database access due to the corruption, use third party SQL recovery applications and correct the issue.

MDF recovery software is a tool to scan, repair and restore the corrupted SQL database in the original view and content. They offer a definite SQL repair help in all the database corruption scenarios. For best cure, choose best help.

Stellar Phoenix SQL Database Recovery uses the most powerful scanning algorithms and repairs them effectively. With Phoenix SQL recovery treatment, you would find an interactive interface to work with and a consistent MDF repair mechanism. This MDF recovery application is found to be compatible with SQL Server 2000 and 2005.

In SQL Server, the BCP utility is meant to copy data, desired among a data file and an instance of MS SQL Server. This copy in a user specified format and can also be used to import and export data into SQL tables and from tables respectively. There are many options which can be used with the command and hence the performance of process can be featured.

But, in many number of cases, this has been seen that the use of command, along with options like SELECT INTO/BULK COPY and IGNORE_DUP_KEY options, can actually threat the database existence. The table corruption may be observed on index pages. This type of corruption has also been reported on the tables having nonclustered index.

When the user chooses to run the DBCC CHECKDB command, he/she may encounter the following error message as a result:

Server: Msg 8951, Level 16, State 1, Line 1
Table Corrupt: Table ‘table_name’ (ID 1941581955). Missing or invalid key in index ‘index_name’ (ID 2) for the row:
Server: Msg 8955, Level 16, State 1, Line 1
Data row (1:365:0) identified by (RID = (1:365:0) ) has index values (store_number = 1211 and ssn = ‘440921916′ and date_worked = Feb 7 2000 12:00AM?|?’?WeG and clock_in_time = ‘16:53′ and clock_out_time = ‘19:08′).

The indexes have gone corrupted which are the performance enhancing objects for database, so SQL repair is must. Actually, to correct the corrupted index issue, you can either drop them to recreate as new, use the DBCC CHECKTABLE command with REPAIR_FAST option, use the DBCC DBREINDEX statement or have complete SQL recovery through some third party applications.

MDF repair software are the sure tools to resolve any type of corruption issues with the SQL Server database. Safe for MDF recovery, interactive interface and perfect scanning of the database, all these features make these applications recommended tools to repair SQL Server database. Just select the SQL repair software wisely, install, click and repair. These MDF repair utilities are quite easy to use and worth in their work.

Perfect MDF recovery is guaranteed through Stellar Phoenix SQL Database Recovery, which is a well-built tool to scan, repair and restore the corrupted database. Phoenix SQL recovery fits well as an aid in all corruption scenarios and corrects corruption for all database objects.

MS SQL Server has offered the database integrity check through a simple command called DBCC CHECKDB. This performs a set of operations and sees if there is any corruption in the database or not. With the help of few SQL repair options, the command can impart repair in many of the cases. The command reports corruption and shows its report in the form of error message, each having a specific meaning and reference.

Now, some database corruption issues have been seen when the database contains sql_variant data type. This is a data type which stores values of diverse SQL Server-supported data types, all in a common place.

DBCC CHECKDB command reports corruption symptoms, with the error messages such as:

Server: Msg 2537, Level 16, State 43, Line 1 Table error: Object ID 587149137, index ID 0, page (1:1325), row 0. Record check (innerLength <= innerColInfo.CbMaxLen () && innerPCol != NULL) failed. Values are 17 and 5.

Or

DBCC results for ‘myvar2′. There are 1 rows in 1 pages for object ‘myvar2′. CHECKTABLE found 0 allocation errors and 2 consistency errors in table ‘myvar2′ (object ID 587149137). repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKTABLE (pubs.dbo.myvar2 ).

This particularly happens when the application loads data into the column of sql_variant data type which contains numeric values. Now, if the data initiates in some other column that is also a sql_variant data type and then, the data is sent on-the-wire by SQL Server. In this condition, data is sent to some other SQL Server or to an intermediate file and the corruption issues are seen with the database.

Microsoft has released its fix through latest service pack of SQL Server, but there is no answer for the corrupted database as such. But fortunately, file repair engineers have, who solve the issue in SQL recovery way. They offer MDF repair software which can scan the database and make repair possible with the use of powerful algorithms.

MDF recovery utilities are designed with the technology to be functional in each corruption case and offer ease of use via the interactive interface.
The best SQL recovery option is available through Stellar Phoenix SQL Database Recovery which is a splendid application and has been instructed to use the algorithms which actually work. This SQL repair software is found to be compatible with SQL Server 2000 and 2005.

Moreover, it will impart MDF recovery for all the database objects and is considered safe as of the read-only conduct. To let experience the interface qualities and operational abilities, manufactures have availed the free demo version of this MDF repair utility on their website.

SQL Server stories are full of incidents in which the user faces several software and hardware problems which are responsible for making the SQL database corrupt. Errors indicate the diversion from the ideal work, which SQL server should perform. One such error is as stated below:

“Error 823
I/O error <error> detected during <operation> at offset <offset> in file ‘<file>’”

Microsoft says that this is with regard to either the system or hardware problems with SQL server. As the direct or indirect result, this situation can make you fall for SQL recovery, so be prepared for it.

Either I/O logical check failure or operating system error can be the prime cause of the stated error message in the logical cause’s category. While operating system error, if read or write Windows API call becomes unsuccessful, the 823 error may be generated. On the other hand, if this call comes out as successful and specific logical checks on the data are not successful, then this form the category of I/O logical check failure. Run DBCC CHECKDB statement and solve this issue and if still, the 823 error is being the headache, see the problem from hard disk problem point o view. In few of the cases, this may also happen that the database may remain logically corrupt, even after running the command, so use SQL repair utilities and proceed.

If this is the hard disk issue, which is responsible for the stated error, replace the hard drive or if, possible, have the correct measures. In error 823, the high chances are for the disk related errors. Get sure about the problem by checking the Microsoft Windows NT system event log for errors.

If the database is physically corrupt, consult MDF recovery services and have your valuable data back. Either, this is the case of MDF repair in logical issues or in physical problems, SQL recovery industry always come with the flying colors.

SQL repair utilities have the scanning procedure and service has manual treatments to extract the data. So, if you don’t have the valid backup, MDF recovery is there for your help.

Stellar Information Systems Limited is the place which will resolve all your SQL recovery queries. The MDF repair services and the intended software, called Stellar Phoenix SQL Database Recovery make SQL repair term complete in each manner.

MDF recovery utility is stuffed with the powerful scanning algorithms and the Class 100 Clean Room facility in SQL recovery are competent to fetch the worth results.

SQL Server database or MDF file comprises of valuable and business important information, but different error messages keep indicating that the safety to the data has not yet been foolproof. The series of 8909 errors is one amongst them which say that the database is not with perfect integrity.

Errors tagged with 8909, may be like:

Server: Msg 8909, Level 16, State 1, Line 0 Table Corrupt: Object ID 1, index ID 0, page ID %S_PGID. The PageId in the page header = %S_PGID.

Or

Msg 8909, Level 16, State 1, Line 1
Table error: Object ID 0, index ID -1, partition ID 0, alloc unit ID 281474983198720 (type Unknown), page ID (53:3) contains an incorrect page ID in its page header. The PageId in the page header = (61:3).
Repairing this error requires other errors to be corrected first.

Or

Server: Msg 8905, Level 16, State 1, Line 1
Extent (1:192) in database ID 10 is marked allocated in the GAM, but no SGAM or IAM has allocated it.

Few 8905 errors will also accompany them. These types of errors can arise while attempting to shrink the corrupt tempdb using DBCC SHRINKDATABASE or DBCC SHRINKFILE commands. These have also been seen during the normal operations with the database, while some users also report that while the deadly symptoms, they can’t backup the database and end users are free from any type of problems.

DBCC CHECKDB is the popular and valuable command for having SQL recovery. But unfortunately, this is also incapable to show the efficiency. Though in few cases, this may report success in SQL repair, but the reality is far behind as corruption symptoms remain the same. This limitation has been covered in the latest service pack of SQL Server 2000.

Restore the database if you have a valid backup or alternatively, create a new database and extract all the possible uncorrupted data to save it to the new one. MDF recovery is important as data worth and so third party applications, meant for the purpose, can serve the cure.

MDF repair software will scan and retrieve maximum possible information and will make it usable for further operations. They can recover all the objects of database.

Stellar Phoenix SQL Database Recovery proves as the most effective SQL recovery solution as of the high scanning ability, read-only design, interactive interface and compatibility with SQL Server 2000 and 2005. This SQL repair product uses the most valuable MDF recovery procedures to extract out the data.

SQL repair can be availed for database objects like rules, defaults, indexes and the included database constraints. Moreover, the additional MDF repair powers add to its functionality.

SQL Server Management Studio is the most important and powerful tool of Microsoft SQL Server, included in MS SQL Server 2005 and later file versions. It is used to configure, manage and administer all of the SQL Server components.

This tool includes both graphical tools and script editors that work with the objects and features on server. A vital feature of the SQL Server Management Studio is Object Explorer that allows you to select, browse and work upon any of the server object.

While SQL Server Management Studio or SSMS is an extremely important tool for SQL Server, but sometimes when you open SQL Server Management Studio and try to connect with the local database, you may fail to do it. Here you may also receive the following error message:

“Database ‘msdb’ cannot be opened. It has been marked suspect”

After this error message, when you see the SQL Server application event log, you will find the following entry:

“The log scan number (152:284:1) passed to log scan in database ‘msdb’ is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error occurred during replication, re-create the publication. Otherwise, restore from backup if the problem results in a failure during startup.”

Grounds of the issue

As stated in the error message, this problem occurs if the database has become suspected. It could be either due to corruption in the database or the log file does not match with the database file.

After the error message, you won’t be able to access anything from your database and may fall in grave situations. Thus, you need to fix the problem as soon as possible to gain access of your valuable data.

Resolution

To handle the database suspect state, Microsoft has provided an inbuilt tool with MS SQL Server, known as sp_resetstatus. It can change the database status and thus could make it accessible again.

But in this case, it won’t be able to fix your problem. It will only let you connect to the SQL Server instances and will let you access other databases. In this case, the data from MSDB won’t be accessed and thus you will have to perform SQL recovery on it.

SQL recovery comes as the last resort to fix all of the MDF corruption related troubles. You can perform SQL repair using MDF recovery software. MDF recovery software are very easy to use and allow you to have Do It Yourself MDF repair.

Stellar Phoenix SQL Database Recovery software is the ultimate solution of all your corruption related troubles. This robust SQL recovery software can achieve MDF recovery for all of the SQL Server objects. You can use this SQL repair software with SQL Server 2000 and 2005 and can end up at absolute MDF repair.

When using SQL code, you generally need a table to store data temporarily to execute the code or query. Temporary tables are basically of four types and used for different kinds of database operations.

Many times when you run an SQL query, which references any temporary table, on the SQL Server 2005 database, the query may fail to execute and you may come across with the following error message:

“Internal error. Buffer provided to read column value is too small. Run DBCC CHECKDB to check for any corruption.”

As suggested in the error message, when you run the DBCC CHECKDB statement on the database for checking out the database corruption, this statement does not show any error message.

After this error message, you can not apply any query on the database and thus can not access data from your database tables. In such situations, you need to identify and fix the problem for getting access of your valuable data.

Grounds of the trouble

This issue occurs because the temporary tables are cached in the SQL Server 2005. These cached tables may damage the table schema if it does not get changed. However, the cached table might be incorrectly used even if the table schema has got changed.

Due to damage to the table schema or database schema, entire MDF file may get damaged and may become completely inaccessible and may finally lead to the nightmare of data loss.

At this point of time, the only thing which can save your data and your business is MDF recovery. You need to repair and restore your corrupted database to make the data accessible. MDF recovery is feasible with the help of SQL recovery software.

SQL recovery software are the third party tools, designed to allow users to have easy and quick SQL repair. The MDF repair software are made available by a number of data recovery companies, but you should always go for the best MDF recovery software to ensure complete and successful SQL recovery.

Stellar Phoenix SQL Database Recovery software is the best ever made and the most influential MDF repair software. This MDF repair software is powerful enough to methodically scan the corrupted database and extract all of the data from it. This outstanding MDF recovery software can perform SQL recovery in all possible cases of corruption.

Phoenix SQL repair software is fully automated and allows you to perform MDF repair for all MDF objects including forms, reports, tables, stored procedures, constraints, rules, checks, triggers, defaults and so on. This SQL recovery software is applicable to MS SQL Server 2000 and 2005.

In database management system, Stored Procedure is a set of SQL statements stored in the database dictionary, which improves the competence, security and usability of the database. It is a database query, stored in the compiled form, with an assigned name.

Stored procedures are mainly used for the data validation and to access control mechanism. Furthermore, these are also used for centralizing and consolidating the logic that was initially implemented to the application.

These are very useful components of database and give substantial performance, improved productivity, abstraction, reduced network traffic, and code reuse like benefits. But, sometimes you may face problems while viewing or using the stored procedures.

When you attempt to see any stored procedure using the Enterprise Manager of SQL Server, you may come across with the following error message:

“Error 0: [SQL-DMO] Object ‘dbo.SP_ProcName’ was not scripted. It is possible that the information in system table ’syscomments’ about the object was corrupt or missing?”

You can delete the stored procedure in this case by right clicking on it and choosing ‘Delete’ option. You can also recreate it using the CREATE PROCEDURE script. But when you try to use the newly created one, you will get the same error message.

Cause

As state in the error message, the problem is due to missing or corrupted stored procedure. The corrupted stored procedure has damaged the database and thus it can not be used now.

The possible reason of corruption in stored procedure may be virus attack, application malfunction, unexpected system shutdown and many alike. Nevertheless the reason, the result is corrupted MDF file and finally the data loss.

In these cases, to save your data and your business, you need to repair and restore the MDF file. It is possible by performing SQL recovery. SQL recovery can easily be performed through MDF recovery software.

MDF recovery software perform quick and easy MDF repair and restore the data in its original state. To ensure the complete SQL repair, you need to opt for the best quality MDF recovery software of trusted data Recovery Company.

Stellar Information Systems Ltd is the most trustworthy and leading data Recovery Company, having solution for each and every data loss posers. For SQL recovery, Stellar gives a tremendously powerful and advanced MDF recovery software known as- Stellar Phoenix SQL Database Recovery.

Phoenix SQL recovery software comes equipped with simple and interactive user interface and thus very easy to use. It can perform SQL repair for all the MDF objects including stored procedures, tables, reports, triggers, constraints and many alike.

Several times when you try to access your SQL Server database, it goes to Suspect Mode. In such cases, there is no way to resolve the problem and the only way, you have to overcome this problem, is to restore it from recent backup. If you don’t have recent backup, you may experience the nightmare of data loss.

An SQL Server database can become suspect due to a number of reasons. Possible reasons include denial of access to the database resources by operating system, and the unavailability or corruption of one or more SQL database files.

To resolve the suspect mode problem, you can use sp_resetstatus command. It turns off suspect flag of the database. It updates the mode and status columns of named database in sysdatabases. You should check the SQL Server error log before using this command. After executing it, stop and restart SQL Server for completing the process.

Though, sp_resetstatus works in most of the cases and resolve the suspect mode problem. But unluckily, sometimes when you attempt it on a database, it may refuse to run and throw the following error message:

“Prior to updating sysdatabases entry for database ‘database name’, mode = 0 and status = 272 (status suspect_bit = 256).
For row in sysdatabases for database ‘ database name’, the status bit 256 was forced off and mode was forced to 0.
Warning: You must recover this database prior to access.”

After this error message, the database remains in the suspect mode and you can’t access anything from it. It is the worst case scenario which a database administrator could face.

In such situations, you need to repair the damaged database prior to use. The MDF repair is possible with the application of powerful third party applications known as SQL recovery software.

SQL recovery software are very easy to use tools which allow you to have perfect MDF recovery in all cases of corruption. SQL repair software perform systematic scan of entire database and extract all of the data from it.

The most important thing, at this point of time, is to select powerful and effective SQL recovery software. The software should be capable of handling all corruption issues and retrieving all the database objects.

Stellar Phoenix SQL Database Recovery is the most influential and robust SQL repair software which is able to repair and restore MDF file in all cases of corruption. Using this SQL recovery software, you can retrieve all of the database objects including tables, reports, forms, macros, database constraints, stored procedures, triggers and so on.

This MDF recovery software comes equipped with interactive user interface and allows you to have easy SQL recovery. To know more about the working and features of this MDF repair software, you can go for its free demo version, available on Stellar’s website.

There are some situations where your MS SQL Server might crash due to hardware problems. In these cases, you need to recover your database, which is possible with the help of transaction log files.

It is very useful method of restoring the MDF file of SQL Server, but sometimes when you attempt to attach the MDF file after recovery, you may fail to do it and might come across with the following error message:

“Error 5171: path……\.mdf is not a primary database file.”

In such situations, most of the database administrators recommend to attach a single file. But here it also doesn’t work. When you use sp_attach_single_db Stored Procedures, you may get the following error message:

“Server: Msg 5172, Level 16, State 15, Line 1
The header for file path……\.mdf is not a valid database file header. The PageAudit property is incorrect.”

After these error messages, none of data from SQL Server remains accessible and it can lead to the nightmare of data loss.

Cause

This problem generally occurs if the MDF file of your SQL Server has got damaged. As stated in second error message, the problem could be due to file header corruption or wrong information in file header.

All such situations lead to the inaccessibility of MDF file and need to repair and restore the database. It is very important to work around this problem, as it may put your business at risk of destruction.
