Looks like prepend doesn't work, but that's ok, I can just hard code
"session_id IN" before the iterate tag. This works, if I wrap the
List in a map with "sessionIds" as the key:
<select id="findCountsBySession" parameterClass="map" resultMap="counts">
SELECT
session_id as id, count(*) count
FROM
events
WHERE
session_id IN
<iterate property="sessionIds" open="(" close=")" conjunction=",">
#sessionIds[]#
</iterate>
GROUP BY
session_id
</select>
This gives me the java.lang.StringIndexOutOfBoundsException: String
index out of range: -2 exception:
<select id="findCountsBySession" parameterClass="list" resultMap="counts">
SELECT
session_id as id, count(*) count
FROM
events
WHERE
session_id IN
<iterate property="value" open="(" close=")" conjunction=",">
#value[]#
</iterate>
GROUP BY
session_id
</select>
Seems like a bug, does anyone else have something like this working
with #value[]#?
