I reverted back to last night's full backup to get it back online. I went through the error log and found the last command that appeared to cause the suspect mode http://dba.stackexchange.com/questions/54375/sql-server-2008-r2-dbcc-checktable-error was on a MERGE on a particular table. I ran DBCC CHECKTABLE on the table and got back the following Msg 2511, Level 16, State 1, Line 1 Table error: Object ID 1253579504, index ID 7, partition ID 72057594230341632, alloc unit ID 72057594364887040 (type In-row data). Keys out of order on page (1:14254237), slots 184 and 185. There are 366539002 rows in 3425599 pages for object "PJM_Prices". CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'PJM_Prices' (object ID 1253579504). repair_rebuild is the minimum repair level for the errors found by DBCC CHECKTABLE (CaisoAnalyzer.dbo.PJM_Prices). DBCC execution completed. If DBCC printed error messages, contact your system administrator. in ERRORLOG Internal database snapshot has split point LSN = 001935ad:00001bf6:0001 and first LSN = 001935ad:00001bf5:0001 Is there possibly a way to put just that table in single user mode or some other trick where I don't have to go into single user mode for the whole database? sql-server sql-server-2008-r2 corruption share|improve this question edited Dec 3 '13 at 20:09 asked Dec 3 '13 at 19:08 Dean MacGregor 269315 also, as for the ERRORLOG issue: connect.microsoft.com/SQLServer/feedback/details/468187/… –swasheck Dec 3 '13 at 20:37 @ Dean, The errorlog message is informational.

operability of SQL Server is based on the severity level of error is encountered on it. SQL Error 7105 that commonly occurs in SQL Server of version 2005 and 2008 with the severity level 22. There are various severity levels set for each error http://www.sqlrecoverysoftware.net/blog/sql-error-7105.html that happen to take place on the Server and the severity level from 20 to 25 http://serverfault.com/questions/115486/why-does-dbcc-checktable-report-errors-on-non-existent-pages is so extremely fatal that they end up terminating connection to the Server. Similarly, the SQL Error 7105 falls under the fatal group of error severity level and hence, Server connectivity is lost making the situation even worse. What Happens When SQL Error 7105 Happens? When executing a query on the server it may come across Msg 7105 as a result of the inaccessibility of dbcc checkdb LOB (Large Object) data which was referenced by the page row of a database. The complete error may look like the following: Download Now Purchase Now Msg 7105, Level 22, State 6, Line 1 Database ID 11, Page (255:177), slot 1 for LOB data type node doesn't exist. This usually is caused by the transactions that can read uncommitted data on a data page. Run DBCC CHECKTABLE. NOTE: Note that the severity level is clearly mentioned as 22 which results dbcc checkdb repair_rebuild in the termination of connection by the server. Grounds Of Error 7105 In SQL When this error takes place in SQL Server, it happens due to any of the three grounds discussed below: Primary: Issue related to database corruption lies within LOB page structures or a database page. Secondary: The query in which failure is being encountered repeatedly is probably using NOLOCK or READ UNCOMMITTED ISOLATION LEVEL query hint. Other: Probably the error is lying within your SQL Server Engine leading to the failure of query with the discussed error. Some Practicable Workarounds The most possible reason of occurrence for error 7105 in SQL Server is due to the primary issue i.e. database corruption within page structure or database page. The severity level of this error i.e. 22 denotes table consistency suspicion. Hence, the following workarounds are suggested as a solution for the respective error: Run DBCC CHECKDB on the Server having the issues. Or run DBCC CHECKTABLE on the respective database table as stated in the error message detect any issues. If the issue is anyhow related to the Server Engine then update SQL Server with the latest available service pack. TIP: For other complete database / database content consistency issue you can also go for restoration through its most recent backup copy available with you. However, the command DBCC CHECKDB / CHECKTABLE will only report the error and its issue and may not be able to resolve the

The record check (valid UDT column) failed. The values are 3 and 0. Right now I'm just trying to understand what this error means and how serious it is - it seems to be some checksum-related error and probably not that severe. Recent backups seem to have the same problem, but it's not a big deal either way because the data can be recreated from other sources. Anyway, I'm trying to get to the bottom of this, maybe understand which rows are corrupted, if there's any particular pattern to it. When I run DBCC PAGE to see what's in there, such as the following statement: DBCC PAGE('MyDB', 4, 129574, 3) It shows nothing. Nada. Zip. Just the standard: DBCC execution completed. If DBCC printed error messages, contact your system administrator. But no error and no page data. In fact, every single error that's coming out of CHECKTABLE has a file/page number for which I get this output from PAGE. I'm also seeing the following error from the CHECKTABLE output, but only sporadically: Table error: Object ID 2020918271, index ID 1, partition ID 72057594196590592, alloc unit ID 72057594190233600 (type In-row data). Page (4:129575) was not seen in the scan although its parent (4:129977) and previous (4:129574) refer to it. Check any previous errors. It looks like it might be related, but I'm not really sure how. The UDT can be relatively large (about 5 KB), so maybe it's split across pages and one of the pages is missing? That's just a wild guess, though. The number of errors coming out of CHECKTABLE also makes it look as if the entire table is like this, but I know that's not the case, because I can read the data just fine. In fact, there's an automated process that runs every day that will, over time, read just about all of the data in this table, and it hasn't rep
