Answered my own question:
I just discovered that I'd missed the subtle syntax difference between
dynamically provided parameters and actual chunks of sql; I need to use
$value$ instead of #value#.
Sorry 'bout that.

Hello -
I'm trying to run an alter table command to swap partitions in a large
Oracle table. I haven't found any documentation regarding alter table
in iBatis specifically, so I'm using the update mapping. Seems
straightforward enough, but for some reason my inline #value#
parameter is not being substituted into the final statement (I think...).
Here's what I've got:
--------
Container: Tomcat 6.0.16
Database: Oracle 10.2.0.4
Driver: ojdbc6-11.1.0.7.0
iBatis Version: 2.3.4.726
SQL MAP (Point.xml):
<sqlMap namespace="Point">
<sql id="pointTable">TRACKLINE_PT</sql>
<sql id="tempTable">TRACKLINE_PT_SWAP</sql>
<update id="swapTempToPart" parameterClass="java.lang.String">
alter table <include refid="Point.pointTable"/>
exchange partition #value#
with table <include refid="Point.tempTable"/>
without validation
update global indexes
</update>
</sqlMap>
JAVA:
public class PointIbatisWriteDAO extends SqlMapClientDaoSupport {
. . .
public void deletePoints() {
SqlMapClient sqlMap = getSqlMapClient();
sqlMap.update("Point.swapTempToPart", "TRACKLINE_PART_01");
}
}
ERROR:
--- The error occurred in gov/noaa/ngdc/mgg/geodas/Point.xml.
--- The error occurred while applying a parameter map.
--- Check the Point.swapTempToPart-InlineParameterMap.
--- Check the statement (update failed).
--- Cause: java.sql.SQLException: ORA-14006: invalid partition name

--------
If I run the the statement with "TRACKLINE_PART_01" hardcoded into the
mapping it works fine, and the logs resemble those from other sql
mappings which use inline #value# substitution and also work. Why
would that substitution not take place? Do I need to do something
different with statements like 'alter table'? Am I missing something
else?
Thanks for you help.
