I just run DBCC CHECKDB in order to check the integrity. After a few minutes I got at the end of http://dba.stackexchange.com/questions/88982/how-to-repair-database-consistency-errors the results the following: CHECKDB found 0 allocation errors and 4 consistency errors in database 'AXPROD'. repair_rebuild is the minimum repair level for the errors found by DBCC CHECKDB (AXPROD). DBCC execution completed. If DBCC printed error messages, contact your system administrator. Since I got 4 consistency errors I would like to know if there is a way to fix this, or a way to get more detailed information about these errors. sql-server dbcc-checkdb share|improve this question edited Jan 10 '15 at 4:00 Paul White♦ 29.2k11163262 asked Jan 10 '15 at 2:54 VAAA 14313 add a comment| 2 Answers 2 active oldest votes up vote 8 down vote I would like to know if there is a way to fix this These consistency errors may be fixable with the REPAIR_REBUILD option of DBCC CHECKDB: Performs repairs that have no possibility of data loss. This can include quick repairs, such as repairing missing rows in non-clustered indexes, and more time-consuming repairs, such as rebuilding an index. As Shanky's answer mentions, any DBCC repair should also be performed inside a transaction, so you can inspect the changes before committing to them. As always, please ensure you have a
Integrity: Interpreting DBCC CHECKDB Results September 3, 2013 by SQLSoldier SQL Server 0 Introduction to Integrity I want to start a short 6 post series to serve as an introduction to integrity in SQL Server. Most posts that I write on this subject http://sqlsoldier.net/wp/sqlserver/introductiontointegrityinterpretingdbcccheckdbresults are for intermediate or advanced users, so this is a break from the normal for me. I think it is a good break though because I think there are very few introductory posts or articles on this subject.
http://itknowledgeexchange.techtarget.com/sql-server/error-handeling-and-dbcc-checkdb/ I was inspired to write this introductory series when I alpha-tested a new free tool from Idera Software being launched today. Idera has created a tool for running and managing database integrity checks. This tool is ideal for dbcc checkdb people who want to simplify running and managing integrity checks of their databases. This free tool from Idera is SQL Integrity Check. Before I continue on, I want to thank Idera for inspiring and for sponsoring this blog series, Introduction to Integrity. The word “integrity” has multiple meanings in the SQL Server world. One meaning deals with the quality of data stored within SQL Server. One form of integrity is maintained through proper data typing, constraints dbcc error messages (default, check, unique, and key), and data validation processes. The other definition of integrity deals with the logical and physical consistency of the underlying structures of a database. Logical and physical consistency is the much more complex of the two, and this is the subject we are going to tackle in this series. Reading Integrity Check Output SQL Server provides a DBCC command for checking the integrity of a database. There are a variety of DBCC commands available, but the only command we are concerned with for this topic is DBCC CHECKDB. DBCC CHECKDB will check the internal structures, metadata, and data in a database. In its simplest form, it can be executed by calling DBCC CHECKDB (?

We hadn't been for a little while due to maintenance window constraints on their old production server. Now that we've scaled the application across 6 different servers we can now do DBCC CHECKDB on the production server regularly to ensure that there aren't any database corruption problems on their production server. As a part of this configuration we wanted to do the DBCC CHECKDB as a part of the backup job so that after the DBCC CHECKDB is complete the databases will then be backed up. The catch here is that we didn't want to have to dig through the errorlog file to figure out what the database was that's having the problem, and we didn't want the job to fail if there was a problem so I started looking at catching errors when running DBCC CHECKDB. Sadly there aren't really any good ways to do this. TRY/CATCH doesn't work because DBCC doesn't actually throw error messages like a normal SQL statement does. It returns the errors, but it doesn't actually throw the errors so the CATCH block isn't actually captured. Running DBCC CHECKDB within an EXEC sp_executesql doesn't catch the error either for the same reason, the error isn't thrown it is simply displayed. (The reason that the errors from DBCC CHECKDB show up in Management Studio in red I would assume is because SSMS is catching the format and displaying it correctly.) To catch the errors I had to resort to some old school "error handeling" using the @@ERROR system function. While this isn't perfect, I'm not looking for perfect here. I'm just looking for something that says that there's an error so that I can send an email when there is an error then continue to loop through the databases looking for others with problems. As this is step 1 of a mu
