SQL Server error on update command - "A severe error occurred on the current command"

Question

Running the following query in SQL Server Management Studio gives the error below.

update table_name set is_active = 0 where id  = 3

A severe error occurred on the current command. The results, if any, should be discarded.

• The logs have been truncated
• there is an update trigger but this isnt the issue
• the transaction count is zero (@@trancount)

I have tried the same update statement on a couple of other tables in the database and they work fine.

DBCC CHECKTABLE('table_name');

gives

DBCC results for 'table_name'.
There are 13 rows in 1 pages for object "table_name".
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

Answer 1

I just had the same error, and it was down to a corrupted index. Re-indexing the table fixed the problem.

Answer 2

In my case,I was using SubQuery and had a same problem. I realized that the problem is from memory leakage.

Restarting MSSQL service cause to flush tempDb resource and free huge amount of memory. so this was solve the problem.

Answer 3

Run DBCC CHECKTABLE('table_name');

Check the LOG folder where the isntance is installed (\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG usually) for any file named 'SQLDUMP*'
