Error description
Comparing a column from a column-organized table with an expression including the SUBSTR function may return wrong results, e.g.: db2 "insert into T(c1) values('201803')" db2 "select C1 from T where substr(C1,1,6) = substr('2018-03',1,4)|| substr('2018-03',6,2)" The problem occurs when the column is defined with string length unit CODEUNITS32 and the SUBSTR expression has constant arguments.
Local fix
Replace the constant SUBSTR expression with a constant, e.g. replace SUBSTR('2018-03',1,4) with '2018' and replace SUBSTR('2018-03',6,2) with '03'.
