SDU Tools: List SQL Server user tables that are heaps (have no clustered index)
Most SQL Server tables should have a clustered index. There are some exceptions to this but it’s a pretty general rule, and if in doubt, you should follow it. (Note that this is not the same as having a primary key).
I regularly come across tables without clustered indexes for all the wrong reasons. So, in our free SDU Tools for developers and DBAs, we added a tool that can look for user tables that don’t have a clustered index. No surprise, it’s called ListUserHeapTables because a table without a clustered index is a heap.
It takes three parameters:
@DatabaseName sysname - the database to look into @SchemasToList nvarchar(max) - a comma-delimited list of schemas to check (or ‘ALL’) @TablesToList nvarchar(max) - a comma-delimited list of table s to check (or ‘ALL’)
