To-number conversion warnings work differenly with CHAR and VARCHAR sp variables. The original revision-IDs are: staale.smedseng@sun.com-20081124095339-2qdvzkp0rn1ljs30 staale.smedseng@sun.com-20081125104611-rtxic5d12e83ag2o The patch provides ER_TRUNCATED_WRONG_VALUE warning messages for conversion of VARCHAR to numberic values, in line with messages provided for CHAR conversions. Conversions are checked for success, and the message is emitted in case failure. The tests are amended to accept the added warning messages, and explicit conversion of ON/OFF values is added for statements checking system variables. In test rpl.rpl_switch_stm_row_mixed checking for warnings is temporarily disabled for one statement, as this generates warning messages for strings that vary between executions.
