iBatis using a set for a resultMap as well as a pa

问题:

I want to pass a Set of Strings in an iBatis query for the parameter map as well as return a collection of strings for the result set.

Is this possible?

Example queries ...

SELECT * FROM some_table t WHERE t.some_column IN (values);

UPDATE some_table t SET t.some_column = 'some_value' WHERE t.other_column IN (values);

If you want to pass a List of Strings as one parameter, for example for building a IN(val1,val2...) query, then you should read about dynamic queries, in particular the Iterate element. See also.

For the return, In SqlMapClientTemplate there is the queryForList method.

As for the Set of String as parameter, I do not know if iBatis handles that; we built an object for that, and when I faced that problem it was in a sql in clause, so I made a loop with comma separated values.
Or you can convert the Set to an HashMap and pass that.
