SQL402B - Table &1 used in hash join step &2

SQL402B
Message Text: Table &1 used in hash join step &2
Cause Text: This message lists the table number used by the hash join steps. The table number refers to the relative position of this table in the query.

If there are two or more of these messages for the same hash join step, then that step is a nested loop join.

Access plan implementation information for each of the hash join step are not available because access plans are not saved for the individual hash steps. Debug messages detailing the implementation of each hash step can be found in the joblog if the query is run in debug mode using the STRDBG CL command.
