DB2 - Problembeschreibung

Problem IC67843 Status: Geschlossen

AN OR PREDICATE CONTAINING INLIST SUBTERM MAY BE REWRITTEN TO UNION

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
An OR predicate can be rewritten to UNION such that the OR 
subterm predicates can be processed individually at each UNION 
leg. To receive this rewrite transformation, the OR subterm 
predicate must meet certain criterion to ensure the superiority 
of query performance. The case to be handled is OR subterm 
predicate is an IN predicate. This IN predicate should have a 
form such that (i) the operand column is a leading index key or 
a column from the index whose leading columns are bound via 
local equality predicate and (ii) IN list elements are composed 
of only constants, host variables, special registers, arithmetic 
operations, datetime operations, string concat, case expression, 
casting functions, and scalar functions.
