DB2 FOR LUW / DB2FORLUW / 980 - DB2

A query being compiled that has a local predicate (LOCPRD) with 
an empty string literal, i.e., '', may cause the instance to 
abend if the following conditions are satisfied: 
 
1) The column (COMPCOL) in LOCPRD is equivalent to another 
column (OTHCOL), e.g., via a join 
2) OTHCOL is also involved in a local predicate (OTHLOCPRD) 
3) LOCPRD is either an equi-join or non-equi-join predicate 
4) OTHLOCPRD is an equi-join predicate 
5) OTHCOL and COMPCOL are both string-type columns 
 
The stack trace from such an abend will look something like: 
 
sqlrxcp1 
sqlnr_seldel_test 
sqlnr_upddelpd_cond 
sqlnr_seq 
sqlnr_rcc 
sqlnr_magic_detail_action 
...

Manually rewrite the query by adjusting the empty strings in 
the2 predicates involved to have the same length as the columns 
 they are being compared against using spaces, e.g., 
VARCHAR_4_COL = '' 
can be safely adjusted to: 
VARCHAR_4_COL = '    '
