Problem summary


    

  • ****************************************************************
* USERS AFFECTED: All users of TABSTATS_TABLE, COLSTATS_TABLE, *
*                 and IDXSTATS_TABLE.                          *
****************************************************************
* PROBLEM DESCRIPTION: When the hidden tables (TABSTATS_TABLE, *
*                      COLSTATS_TABLE, and IDXSTATS_TABLE) are *
*                      enabled, SQLCODE -404 is returned for a *
*                      simple Explain on a query.              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When the three hidden tables (TABSTATS_TABLE, COLSTATS_TABLE,
and IDXSTATS_TABLE) are created and enabled, an Explain of a
query would try to populate the hidden tables.  This will cause
an error with SQLCODE -404.  The error message is as follows.
"THE SQL STATEMENT SPECIFIES A STRING THAT IS TOO LONG".

Additional Keywords:
SQLEXPLAIN SQLCODE404

    



Problem conclusion


    

  • When populating the hidden tables, DB2 did not align some of the
fields in the record correctly. These fields are now aligned to
fix the problem.
