Apology accepted.
First off lets take a trip down the old API.
from http://java.sun.com/j2se/1.5.0/docs/api/java/util/HashMap.html
"This class makes no guarantees as to the order of the map; in particular,
it does not guarantee that the order will remain constant over time."
Second, you can create the order when you pull them out. But I am guessing
that you are using some sort of iterator to loop through the map and print
out the results, since you dont know the column names. I can only suggest
that you try to create some result classes and not use maps. Maps are great
for parameter maps but are generally frowned upon as a result class. As a
last resort you might get away with trying to use LlinkedHashMap from
java.util.

Greetings,
I'm kind of new to Ibatis, so if I'm missing the obvious, let me apologize
right up front.
Nonetheless, here is my problem. I am using a HashMap as the resultClass
to retrieve results from a DB2 database. My problem is the column order
(not row order) returned appears to be almost random. How do I "force"
Ibatis to return the columns in the same order as they appear (returned)
in the SQL query?
For example, here is my query:
SELECT A as COL_A, B as COL_B, C as COL_C from tablexxxx
My results can be COL_B, COL_A, COL_C..........or COL_C, COL_B,
COL_A..........or , etc, etc.
I have logged java.sql and the columns are being returned in the proper
order, but eventually they get "realigned". Can someone explain to me
why? I'd really appreciate it. I know I can use a ResultMap to have the
columns listed in the proper order, but what I'm trying to do is use the
same Ibatis select statement to "service" arbitrary SQL statements. Hope
I'm making sense.
<select id="getReport" parameterClass="com.ibm.bean.ReportDefinition"
resultClass="java.util.HashMap" remapResults="true">
$query$
</select>
