> Key: IBATIS-441
> URL: https://issues.apache.org/jira/browse/IBATIS-441
> Project: iBatis for Java
> Issue Type: Bug
> Components: SQL Maps
> Affects Versions: 2.3.0
> Environment: Mysql Server version: 5.0.32-Debian_7etch1-log
> mysql-connector-java-5.0.6-bin.jar
> ibatis-2.3.0.677.jar
> Reporter: Arnaud Lemaitre
> Assignee: Clinton Begin
> Priority: Blocker
> Fix For: 2.3.1

> the following iBATIS code can not retrieve the 2 expected result sets. plain
> JDBC equivalent is provided and is working properly.
> platform specific note :
> multiple queries (allowMultiQueries=true on JDBC url) is not working for
> Mysql server 4.0.24 (tested). apparently requires higher version > 4.1
> (following tests have been done using Mysql 5.0.32)
> Here is my Code (for test purpose) :
> ...
> List results = null;
> SqlMapClient sqlMap = IbatisUtil.getSqlMapInstance();
> try{
> results = sqlMap.queryForList( "test" );
> }
> catch( SQLException sqle ) {
> throw CoreException.wrap( sqle );
> }
>
> final Logger logger = Logger.getLogger( MyCLass.class );
>
> logger.info ( "results.size() = " + results.size() );
> ...
> mySqlMap.xml :
> <?xml version="1.0" encoding="UTF-8" ?>
