Hello:

I have a list of School objects which I'm passing to a query. The OpenSchool object has two properties, school and district. I'm sort of new to iBatis so I may be missing something here but I have the following query:

<select id="getSchoolData" parameterClass="list" resultClass="OpenSchool">
SELECT schoolID, districtName FROM organizations
<dynamic prepend=" where school in ">
<iterate open=" (" close=") " conjunction=",">
#school[]#
</iterate>
</dynamic>
AND district= #district#
</select>

The value of district in the entire list is always the same, say 'ABC'. I want the query to just take one of the district values in the list but include an IN clause with all the schools. I'm not telling iBatis the right thing, obviously (see below). I don't see any dynamic SQL technique to solve this. What is the best solution?


com.ibatis.common.jdbc.exception.NestedSQLException:
--- The error occurred in xxx/xxx/xxx/xxx/xxx/xxxx/xxx/District.xml.
--- The error occurred while preparing the mapped statement for execution.

I have the answer . . . use a Map with school having an Arralist and district having a single value.
Thanks.
 
It is sorta covered in the JavaRanch Style Guide.
