Niels:
Thank you for the idea.
However, it seems not work.
Everytime, I tried to run. It just throws exception.

===================================================================
I use it as:
<dynamic removeFirstPrepend="true">
<isNotEmpty prepend="OR" property="fields[0].value" >
p.PMT_FISCAL_YR = #fields [0].value#
</isNotEmpty>
<isNotEmpty prepend="or" property="fields[1].value" >
p.PMT_DEPOSIT_DT = TO_DATE(#fields[1].value#, 'MMDDYYYY')
</isNotEmpty>
<isNotEmpty prepend="or" property="fields[2].value" >
c.CORP_ID = #fields[2].value#
</isNotEmpty>
</dynamic>
======================================================================

You should use removeFirstPrepend="true" on the dynamic-tag, this causes iBATIS
to skip the first prepend encountered.
Hope this helps,

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

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.

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. Their value can not be determined before hand.
Besides of doing the join of the tables, I want to have a dynamic where clause so that the where
clause syntax is determined by the value in the fields.
The statement below does not run well.
How can I fix it ?
Thanks,
John Chien
