Do you want to select all tables that have rows? See
How Many Records Are There in your Database?[
^].
That would be:
SELECT SYS_OBJ.NAME AS "TABLE NAME"
, SYS_INDX.ROWCNT AS "ROW COUNT"
FROM SYSOBJECTS SYS_OBJ, SYSINDEXES SYS_INDX
WHERE SYS_INDX.ID = SYS_OBJ.ID
AND INDID IN(0,1)
AND XTYPE = 'U'
AND SYS_OBJ.NAME <> 'SYSDIAGRAMS'
AND SYS_INDX.ROWCNT > 0
