Data Conversion Issues With MySQL Driver 5.0.8

The MySQL JDBC driver version 5.0.8 may cause data conversion errors in the BA Server. For example, SQL statements that convert a numeric field to a string are returned as a string with version 5.0.7, but return as a byte array in 5.0.8. To solve this problem, you must replace the mysql-connector-java-5.0.8.jar with the mysql-connector-java-5.0.7.jar in your client tool or application server's lib directory.
