RE: Extending IBATIs
Does iBATIS use Introspector and BeanInfo? If it does (and it should!), then you can create a custom BeanInfo class that defines the getter/setter methods for particular properties.

RE: conditionally add a table to the from clause just once if either or both of two parameters is not empty
Perhaps moving that logic out of your xml file into Java land.
Assuming you have a Map as the parameter.
boolean useSupplierForParts =
Boolean.valueOf(parameters.containsKey(supplierCompanyId) ||
parameters.containsKey(supplierRef));
Parameters.put(supplierTable, useSupplierForParts ? ,
suppliers_for_parts sp : );
Or, if you have a parameter class:
class MyParameter {
// all sorts of goodies in here...
public String supplierTable() {
return (supplierCompanyId != null || supplierRef != null) ? ,
suppliers_for_parts sp : ;
}
}
In your map file:
SELECT whatever FROM whatever w, other_table ot, $supplierTable$

ibatis2.2 java5 and 6 on winXpSp2
I'm using the code below to conditionally add a table to the from clause
of my sql if one or other or both of two parameters is not empty. (The
tricky bit is not to include add the table twice).
The following works, but I wondered if there was a simpler way that
avoids my ugly /*dummy*/ cludge.
(Without the /*dummy*/ nothing is ever generated.)

I have a setter which does no accept null values for a list, ie:

I did not find yet any decent way to map a nullvalue to an empty list, I

For now dumbest thing I could do was to remove the check and do nothing

RE: Getting straight at the ResultSet
iBATIS is used to wrap JDBC, so that you don't have to deal with the low level details. If you want to deal with the low level details, simply don't use iBATIS. You are going to have an overhead if you use wrapper, but the overhead is probably minimal. Do things the normal iBATIS way, and if you find out it is too slow, do some profiling, don't just assume its because of a particular wrappers overhead.

Looks like a problem with the way ibatis handles collections. Is it
possible to iterate over the addresses, rather than manually select [0]

Also, might it be better design (if there is always going to be exactly
two) to have them be individual properties? streetAddress,

RE: Flushing of oscache in a cluster ?
We ran into a similar problem (same situation) Although, we happened to have an RMI connection between the tool and front-end, so we used that to send "flush" commands. I wouldn't recommend that though, trying to keep the two synchronized was a pain. Actually, I don't know much about iBATIS's caching models. Maybe someone can tell us. Is there an easy/efficient way to make iBATIS recognize updates made by a separate process, and recache the new results? My thoughts on it are that any JVM which caches through ibatis should be the only process to update the data. But, this seems too strict for real-world applications.

RE: Update query
I think his parameter class has a property named "track" which is a bean with a property named "id". Anyway, I would probably debug (either set a break point, or just println) the value of track and track.getId() before calling this query.

dynamic script's
Is there a way to run an SQL script from iBATIS? Such as: INSERT INTO foo (#bar#, #baz#); INSERT INTO ho (#hum#); Also, if there is, is it possible to dynamically generate the SQL to do so? Eg: INSERT INTO foo (#bar#, #baz#); iterate property=hosINSERT INTO ho (#bar#, #hos[]#);/iterate Thanks.
RE: dynamic script's
Perhaps. It might be nice to have some sort of scripting support though. Where you can at least chain operations together. Maybe something like: batchTransaction id="deepInsertPost" parameterClass="map" call insert="insertPost"/ iterator property="postData.authors" call insert="insertAuthorMap"/ /iterator /batchTransaction insert id="insertAuthorMap" INSERT INTO authorMap (#post.id#, #authors[].id#) /insert I certainly could write this in java, but it seems generic enough that it might be nice to support it at this level. From: Jeff Butler [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 23, 2006 12:52 PMTo: user-java@ibatis.apache.orgSubject: Re: dynamic script's The answer is yes - if the driver supports it. If your driver supports multiple SQL statements in a single prepared statement, then you can do it. iBATIS doesn't to anything to support or deny this function - it's totally dependant on the driver support. iBATIS will only prepare one statement. In my opinion, this is a bad idea even if the driver supports it. I think it's better to start a transaction and make multiple calls to the different insert statements. More portable, and probably more maintainable.

M:N question
I have something like the following:
class Foo {
Integer fooId;
String name;
MapInteger, ListInteger bar = new HashMapInteger,
ListInteger();
// getters/setters bellow.
}
Table foo has (fooId, name) and table barMap has (fooId, a, b)
select id=getFoo resultMap=fullFoo
SELECT * from foo join barMap using (fooId) WHERE fooId = #fooId#
/select
My question is... What would the resultMap have to look like to handle
bar
Or can it handle it directly?
Map from id-list
I have a table that looks something like this: external_maps Parent externalId type 1 1 1 1 2 1 1 3 1 1 8 2 1 9 2 1 16 6 I want to do a query like SELECT externaId, type FROM external_maps where Parent=%parent% I want to get a result that is a MapInteger, Integer[] (or MapInteger, ListInteger) where the key is type and the Integer[] (or ListInteger)) is the list of externalId values. Will queryForMap do this? If not, is there another (easy) way to get this result? Thanks, Daniel.

RE: One query populating *multiple* lists per object returned
Honestly, the solution I would choose is very different Make a "Pets" table that has both dog and cat :-) Or, if you must use this schema... When you query for people, do one query for "People with Cats", and one for "People with Dogs" and then merge the results. From: Jeff Butler [mailto:[EMAIL PROTECTED] Sent: Thursday, May 11, 2006 2:03 PMTo: user-java@ibatis.apache.orgSubject: Re: One query populating *multiple* lists per object returned It's not really a stupid question. The problem is that adding the Dog table to the join list will, in effect, create a cross join between dog and cat - causing lots of data to be repeated as you've seen. There's nota great solution that I can think of. One solution would be to use the iBATIS group by solution and a join for one of the lists (cats) - as you've already accomplished. For the other list (dogs), you can populate it with a second query sort of like this: resultMap id="personMap" class="foo.bar.Person" groupBy="personID" result property="personID" column="personID"/ result property="personName" column="personName" / result property="cats" resultMap="Persons.catsMap"/ result property="dogs" column="personId" select="getDogsByPersonId"//resultMap I haven't tried this for real, but I think it will work. This is still an N+1 query, but at least it's not 2N+1! Another thought is that you could write your own List implementation that would not allow duplicates. Then it could all be done in one query because you would catch and throw out the duplicates in Java code. As I think about it, I might like this solutionbetter. There's still a bunch of duplicate data coming back from the DB, butthere's only on DB call.

Where I'm running into trouble is I want to have multiple Lists populated per object.

Table alias in results map.
I want to perform a query like: select id=getData resultClass=map parameterClass=string Select * FROM data AS `root:data` JOIN other AS `root:other` JOIN something as `root:other:something` WHERE $where$ /select The tables data, other, and something may or may not have similarly named columns. The aliases correspond to bean's in a map. ---CODE--- Map myQuery = new HashMap(); myQuery.put(root:data = new DataBean()); myQuery.put(root:other = new OtherBean()); myQuery.put(root:other:something = new SomethingBean()); sqlMap.queryForObject(getData, where, myQuery); -- Unfortunately, ibatis seems to look only at the column name, not the table name. I would use result maps, but the query is way to dynamic. My current kludge aliases EVERY column. This works, but is a somewhat painful hack of introspection, and may be a performance bottleneck. Is there any way to tell ibatis to use the table names as part of the result map? Much thanks in advance. Daniel.
HashMap results and column aliased with '.' in the name.
I want to get a result back as a HashMap with all the columns in the result being keys in the map. It makes sense for my application to have '.'s in the column names, but ibatis is trying to map those to properties of Object instances. Is there any way to tell ibatis to ignore '.'s in the column name, or do I have to find a different delineator?
