Indexable predicates are the one which match with index
entries. It depends on the indexes that are available and
the access path chosen at bind time.
For example,if the employee table has an index on the
column LASTNAME,
the following predicate can be a matching predicate:
SELECT * FROM emp WHERE LASTNAME = 'SMITH';
Stage 1 predicates are the predicates which are processed
by Data
manager component of DB2 as soon as it recieves data from
the buffer manager.
Some examples are:
COL BETWEEN value1 AND value2
COL IN (list)
COL LIKE host variable
