Hi All,
    I was wondering if batch update is possible in iBatis.

I have a bean TableList which I would like to update
TableList
    private java.lang.String dbName;
    private com.students.vo.Table[] tables;

Table
    private int studentId;
    private int class;
    private java.lang.String studentName;
    private java.lang.String classTeacher;
    private com.students.vo.Subject[] subjects;


My SQLMap file looks like this

<sqlMap namespace="ReplicationData">

    <typeAlias alias="tableList" type="com.students.vo.TableList" />
    <typeAlias alias="table" type="com.students.vo.Table" />
    <typeAlias alias="subject" type="com.students.vo.Subject" />

    <update id="updateTable" parameterClass="tableList">
        update $dbName$..studentInfo set
        <iterate property="tables">
            StudentId=#tables[].studentId# where
            name=#tables[].studentName#
            classInCharge=#tables[].classTeacher#
        </iterate>
    </update>

</sqlMap>

But whenever i execute my query, I get the following error

2006-01-09 19:27:23,210 +0530 ERROR [EDSUtils][http-8080-Processor24] -
