Problem with sql statement, help wanted.

[Sophia <jd...@telenet.be>]

Would anyone help me.

When I use this: 

List tmpList = accountList2Dao.selectByAccountList2(account2Example);

And this in my sqlmap:

<select id="selectByAccountList2" parameterClass="model.AccountExample" resultMap="abatorgenerated_AccountResult">
    Select number, etc……… from ${schema1}.account where number in 
    (select number from ${schema1}.account where substr(number,5,4) between ‘2002’ and ‘2006’ and office = ‘L2’)
  </select>

I get al the data that I want, and it works fine.
The problem is that the sql is dynamic, I mean that the data 2002 – 2006 and L2 is inputted by the user thru a webpage.
When I rewrite in the past my application to Ibatis I have no problem with any select, insert, delete statement (Abator)
But when I now want to write my own specific sql, it will not work.

Now, my problem is when I use this :

account2Example.createCriteria().andNumberDateBetween(startdate, enddate).andOfficeEqualTo(office);

and this as sql

<select id="selectByAccountList2" parameterClass="model.AccountExample" resultMap="abatorgenerated_AccountResult">
    Select number, etc……… from ${schema1}.account where number in 
    (select number from ${schema1}.account )
  </select>

I get errors, can anyone tell me a easy way to write your own sql statements in Ibatis?
Help and suggestions are appreciated.

Sophia.

You've got 'dynamic' SQL for the "${schema1}" part, but for changing the
values in the select queries, you just need the normal ibatis usage, i.e.

    ...between #startYear# and #endYear# and office = #office#

Note: This assumes that your parameterClass class (model.AccountExample) has
either bean properties or accessors for the '#' values, e.g. a 'startYear'
field or a 'getStartYear()' method, etc...

See also http://cwiki.apache.org/WICKET/ibatis.html for an example...

You won't be able to use ibator's Example class here - this is a
specialized class and will only work with the ibator generated
*ByExample methods.

So you'll need to write your own parameter class, or use a HashMap.

This is pretty basic iBATIS stuff - I suggest you take a look at an
iBATIS tutorial somewhere.
