Problembeschreibung: | |
A query containing a predicate of the form "<CONCAT expression> = G'constant'" may return wrong results. The CONCAT expression must be a concatenation of one or more GRAPHIC columns or GRAPHIC constants and the result size of each side of the predicate must be the same. Here are some examples of problematic queries: CREATE TABLE T1 ( G1 GRAPHIC(4), G2 GRAPHIC(3)) ); SELECT * FROM T1 WHERE ( G1|| G2 ) = G'ABCDXYZ'; SELECT * FROM T1 WHERE G'ABCDXYZ' = ( G'ABCD' || G2 ) | |

Local-Fix: | |
