Question

I want to check in Transact SQL if a specific column in a table has statistics and if so to get them all.

Answer 1

This query should do it.
I use it in a stored proc that browse the DB to find stats.
Works in SQL Server 2005 and probably older version as well.

SELECT S.NAME FROM   SYS.OBJECTS AS O        INNER JOIN SYS.STATS AS S          ON O.OBJECT_ID = S.OBJECT_ID        INNER JOIN SYS.STATS_COLUMNS AS SC          ON SC.OBJECT_ID = S.OBJECT_ID             AND S.STATS_ID = SC.STATS_ID WHERE  (O.OBJECT_ID = OBJECT_ID('MyTable','local'))        AND (O.TYPE IN ('U'))        AND (INDEXPROPERTY(S.OBJECT_ID,S.NAME,'IsStatistics') = 1)  /* only stats */        AND (COL_NAME(SC.OBJECT_ID,SC.COLUMN_ID) = 'MyColumn')
