We have a very old database running on SQL Server 2008 R2. The database is running in 2000 (80) compatibility mode and has oodles of NON-ANSI joins in stored procedures, views and functions.
We need to update this database to at least 2005 compatibility mode to enable the use of CTE SQL,
ROW_NUMBER OVER (PARTITION BY) and so on.
When we first upgraded to SQL Server 2008 R2 we obviously ran Upgrade Advisor 2008 R2 first which highlighted all SQL that had non-ansi joins, at the time we just ignored them and put the database in SQL Server 2000 (80) compatibility mode.
Our problem now is that SQL Server 2008 R2 Upgrade advisor will no longer work for us as the version isn’t supported (as we’re already using that version), and 2000 (80) databases aren’t supported in the 2012 Upgrade advisor either.
My question, short of scripting the whole database and painstakingly going through it checking for
*=* etc, is there a tool we can use to detect all procs, views and functions that contain these joins so we can get them re-written.
This may produce some false positives (e.g. you may have
*= in a comment), but should be a good start:
SELECT obj = QUOTENAME(SCHEMA_NAME(o.[object_id])) + '.' + QUOTENAME(o.name), o.type_desc FROM sys.sql_modules AS m INNER JOIN sys.objects AS o ON m.[object_id] = o.[object_id] WHERE m.definition LIKE '%=*%' OR m.definition LIKE '%*=%';
The syscomments compatibility view contains a copy of the code for all stored procedures, triggers, functions and similar objects. You can easily search it using “LIKE” criteria to find a list of object IDs that need to be updated.
