You should use removeFirstPrepend="true" on the dynamic-tag, this causes iBATIS to skip the first prepend encountered.
Hope this helps, Niels ________________________________________ From: John Chien [mailto:[EMAIL PROTECTED] Sent: maandag 14 november 2005 18:30 To: [email protected] Subject: Re: Dynamic statement Nathan: How can I turn on the logging of ibatis ? The statement just does not run. I think the problem is that the three statement in the <dynamic> </dynamic> will produce something like (OR <st1> OR <st2> OR <st3>) Thus the where clause will become like: WHERE p.CORP_ID = c.CORP_ID AND c.CORP_ID = a.CORP_ID AND (OR <st1> OR <st2> OR <st3>) which certainly does not make sense. However, I do not know I can get rid of the first OR because any of three fields might have value or no value. Thanks, John Chien Nathan Maves wrote: First off by "not run well" do you mean that there is an error? if so please post it. Second turn on logging to make sure the sql appears as you would expect it to. Third it appears that you are sending in an array of objects as parameters. I would suggest that you use a java bean with the 3 properties ( year, deposit, corp_id), or a map of these. This will enable you not to hard code the array indices. nathan On Nov 14, 2005, at 9:53 AM, John Chien wrote: Dear Sir: I have a question related to dynamic statement As shown below, I have a select statement for data in three tables The GUI has three input fields.
