How to use an IN clause in iBATIS?

Question

I'm using iBATIS to create select statements. Now I would like to implement the following SQL statement with iBATIS:

SELECT * FROM table WHERE col1 IN ('value1', 'value2');

With the following approach, the statement is not prepared correctly and no result returns:

SELECT * FROM table WHERE col1 IN #listOfValues#;

iBATIS seems to restructure this list and tries to interpret it as a string.

How can I use the IN clause correctly?

Answer 1

Here's a blog post that answers your question:

iBatis: Support for Array or List Parameter with SQL IN Keyword

<select id="select-test" resultMap="MyTableResult" parameterClass="list">
select * from my_table where col_1 in
  <iterate open="(" close=")" conjunction=",">
   #[]#
  </iterate>
</select>

And in Java you should pass in a java.util.List. E.g.

List<String> list = new ArrayList<String>(3);
list.add("1");
list.add("2");
list.add("3");
List objs = sqlMapClient.queryForList("select-test",list);
