Problem IC97128 | Status: Geschlossen |
DB2LOOK MAY GENERATE THE SAME PREDICATE TO MIMIC STATISTICS FOR UNIQUE INDEXES. | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 | |
Problembeschreibung: | |
The db2look with -m option can generate the same predicates like as below against different indexes on the same table. WHERE COLNAMES = ' ' AND TABNAME = '<tabname>' AND TABSCHEMA = '<schema>'; COLNAMES is valid only if each column name is less than 30 bytes and if there are fewer than 16 columns in the index. Otherwise, the value can be blank. As the db2look uses COLNAMES to mimic index stats against primary key index and indexes for unique constraint. So db2look generates an invalid update statements to mimic index stats if a table has more than one indexes meet above conditions. | |
