----------------------------------------

I observe the same troubles with MySql. I test different versions. The last version of the MySql JDBC connector (5.1.12) I found correct a little this kind of errors.

> Approximately 20 queries are producing unexpected results when being pushed down to  MySql.   One example query and resulting error is below.    Per Steve H this is  a defect for MySql 5.0.15 and later.  We need to add compensation logic to deal with non-ASCII range values.
> SELECT intkey, CHR(CONVERT(bigintegervalue, integer)) FROM BQT1.MediumA WHERE (IntKey > 32) AND (IntKey < 127) ORDER BY intkey
> Error occurred on connector MySQL_Push<5> - Invalid conversion from type class com.metamatrix.common.types.BlobType with value 'javax.sql.rowset.serial.SerialBlob at 1b1395dc' to type class java.lang.Character
