遇到一个sqlmap配置的问题,是不是ibatis的#和$不能混用,或者是别的原因.

为了做一个通用的修改方法,当然表结构也是一样的.
写了如下的sqlmap配置,但是在运行时报了一个Invalid column index的错误,log在sqlmap下面,不知道这里是什么原因,希望有人能帮忙解答一下.

<parameterMap id="editI18nInfoParam" class="map"> 
        <parameter property="tName" javaType="string"/> 
		<parameter property="columnName" javaType="string"/> 
		<parameter property="columnValue" javaType="string"/> 
		<parameter property="locale" javaType="string"/>
		<parameter property="keyColumn" javaType="string"/>
		<parameter property="key" javaType="string"/>
		</parameterMap> 
		<update id="editI18nInfo" parameterMap="editI18nInfoParam">
			<![CDATA[
				update $tName$ set $columnName$=#columnValue# where vclocale=#locale# and $keyColumn$=#key#
			]]>
		</update>
