Hello
I'm trying to troubleshoot a query for a developer that is exclusively locking a number of system tables during execution for several minutes:
| sysschobjs |
| sysallocunits |
| syscolpars |
| sysrscols |
| sysidxstats |
The query is a MERGE statement that uses a linked server in the SELECT to join tables from a database on a remote server with a local table. The merge is on a local table. My suggestion has been to redevelop the stored proc and use SSIS to negate the need for a linked server. I would still like to understand this further as I am unable to explain why the system tables are being locked exclusively when only one local user table is being updated?
Thanks
Adam
