Usa la query dinamica Ibatis in modo corretto??
es.:
<select id="mySelect" resultClass="long" >
SELECT COUNT(*)
FROM myTable
<where>
<isNotEmpty prepend="AND" property="myInClauseValues" >
myTable.columnA IN
<iterate property="myInClauseValues" open="(" close=")" conjunction=",">
#myInClauseValues[]#
</iterate>
</isNotEmpty>
</where>
</select>
