It doesn't look to me like you really want 'where status ='. Certainly the
generated SQL doesn't make any sense. Try something like this:
<update id="updateStatus" parameterClass="java.util.Map">
UPDATE OTM_STAGING SET STATUS = #status#
<dynamic prepend="where SEQUENCE in">
<iterate open="(" close=")" property="sequenceList"
conjunction=",">
SEQUENCE = #sequenceList[]#
</iterate>
</dynamic>
</update>
I've got something similar to that which is working fine for me with an
Oracle DB. It should produce a statement like ' UPDATE OTM_STAGING SET
STATUS = ? where SEQUENCE in (1,3)'

because there are yet no chains on our feet.

Please respond to Re: Execute batch process for
[EMAIL PROTECTED] Update statement
apache.org
The execute batch is not working for me.
Here is the sql-map config
<update id="updateStatus" parameterClass="java.util.Map">
UPDATE OTM_STAGING SET STATUS = #status#
<dynamic prepend="where">
<iterate property="sequenceList">
SEQUENCE = #sequenceList[]#
</iterate>
</dynamic>
</update>
Here is the SqlMapClient's code
public static int updateStagingTableStatus(ArrayList sequences, String
newStatus)
throws SQLException
{
int totalUpdatedStatus = 0;
Map parameterMap = new HashMap();
try
{
sqlMapper.startTransaction();
parameterMap.put("sequenceList", sequences);
parameterMap.put("status", newStatus);
sqlMapper.update("updateStatus", parameterMap);
totalUpdatedStatus = sqlMapper.executeBatch();
sqlMapper.commitTransaction();
}
catch(SQLException sqlEx)
{
logger.error("SQLException " +sqlEx);
}
finally
{
try
{
sqlMapper.endTransaction ();
}
catch(SQLException sqlEx)
{
logger.error("SQLException " + sqlEx);
}
}
return totalUpdatedStatus;
}
Here is the method call:
logger.debug("Update staging table");
ArrayList tempSeq = new ArrayList();
tempSeq.add(new Integer(1));
tempSeq.add(new Integer(3));
int updateCount = XmlService.updateStagingTableStatus(tempSeq,
"test_status");
logger.info("updateCount in server "+updateCount);
Here is the debug log:

--- Check the statement (update failed).
--- Cause: java.sql.SQLException: ORA-00933: SQL command not properly ended
===========================================
What should I fix in the code which gives me something like:
PreparedStatement prepStmt = con.prepareStatement( "UPDATE OTM_STAGING SET
STATUS = ? WHERE SEQUENCE = ?");
for (int i = 0; i < sequenceList.size(); i++)
{
prepStmt.setString(1, "updatedStatus");
prepStmt.setInt(2, sequenceList[i]);
prepStmt.addBatch();
}
int [] numUpdates=prepStmt.executeBatch();
Thanks

Please respond to Re: Execute batch process

I think u need to use <iterate> for this query ,take a look at IBATIS
developer guide ,they have examples on this .
Thanks

Jay,
I saw your posting in iBATIS forum with subject line "iBatis batch
executing same performance as Jdbc - Thanks!"
I am using iBATIS 2.3.0 and do not have any DAO (no Spring). My requirement
is to run execute batch update for prepared statement :
update otm_staging set status = 'Processed' where sequence = ?
Where 'sequence' will get values from array of integer like {1, 2, 3, 5, 7,
9, 11, 12, 14 ........ }
How should I configure my sqlMap resource xml file for the query? Can I
still use your method
'private Object batch(SqlMapClient sqlMap, int batchType, String
methodName, Object argument)'
from the posting ?
thanks
jasmin
