RENAME TABLE does not update the SYSCAT.TABLES STATISTICS_PROFILE column with the new renamed table name. The STATISTICS_PROFILE registers the Runstats statement when the SET PROFILE option is specified during Runstats. Here is an example: db2 create table chrisjg.test (c1 int) DB20000I The SQL command completed successfully. db2 runstats on table TABSCHEMA.test with distribution set profile only DB20000I The RUNSTATS command completed successfully. db2 select 'before',char(tabschema,20) as sch, char(tabname,20) as tab, substr(statistics_profile,1,40) as stat_profile from syscat.tables where tabschema='TABSCHEMA' 1 SCH TAB STAT_PROFILE ------ -------------------- -------------------- ---------------------------------------- before TABSCHEMA TEST RUNSTATS ON TABLE "TABSCHEMA"."TEST" ON AL 1 record(s) selected. db2 rename table TABSCHEMA.test to zzz DB20000I The SQL command completed successfully. db2 select 'after rename',char(tabschema,20) as sch, char(tabname,20) as tab, substr(statistics_profile,1,40) as stat_profile from syscat.tables where tabschema='TABSCHEMA' 1 SCH TAB STAT_PROFILE ------------ -------------------- -------------------- ---------------------------------------- after rename TABSCHEMA ZZZ RUNSTATS ON TABLE "TABSCHEMA"."TEST" ON AL 1 record(s) selected. : | |
