tag:old.nabble.com,2006:forum-360Nabble - iBATIS2009-11-08T22:43:14ZThe iBATIS Data Mapper framework makes it easier to use a database with Java and .NET applications. iBATIS couples objects with stored procedures or SQL statements using a XML descriptor. iBATIS home is <a href="http://ibatis.apache.org/" target="_top" rel="nofollow">here</a>.tag:old.nabble.com,2006:post-26261898ibator and default column value2009-11-08T22:43:14Z2009-11-08T22:43:14ZTomáš Procházka-2<br>Hi.
<br><br>I tested now new commit of ibator with iBatis support, it works great.
<br><br>I have only question. It's (or will be) possible generate also default value to class fields, according to default value in DB? Some column has NULL, another 0 or true/false. If new instance of domain class will be have default value it's easier to insert it in to table.
<br><br>And it's possible something like incremental update od generated code? If I add some new column to DB table? If I own query or methods to generated code it will be lost during next generate.

I won't do a formal
<br>release for a few days as I need to update the docs, but feel free to
<br>check it out and play with it. Ibator is now built with Maven rather
<br>than Ant, so you'll need to know how to do a Maven build. All the
<br>tests pass, but there might be some situations I've not anticipated.
<br>Let me know if you encounter any difficulties. The SVN link is here:

<br> 3, BTW) there is no class named "POOLED". Comparing the iBatis 3 PDF
<br>to the iBatis 2 sample, configuration of the dataSource appears to be

The Pool.* options are what you need. This is just an example, you should set whatever timeout parameters you need (in ms).
<br><br><transactionManager type="JDBC">
<br> <dataSource type="SIMPLE">
<br> <property name="JDBC.Driver" value="${driver}"/>
<br> <property name="JDBC.ConnectionURL" value="${url}"/>
<br> <property name="JDBC.Username" value="${user}"/>
<br> <property name="JDBC.Password" value="${password}"/>
<br>
<br> <property name="Pool.TimeToWait" value="2000"/>
<br> <property name="Pool.PingQuery" value="SELECT 1"/>
<br> <property name="Pool.PingEnabled" value="true"/>
<br> <property name="Pool.PingConnectionsOlderThan" value="600000"/>
<br> <property name="Pool.PingConnectionsNotUsedFor" value="600000"/>
<br> </dataSource>
<br> </transactionManager>
<br><br>Hopefully this helps you! Take a look at the javadoc for com.ibatis.common.jdbc.SimpleDataSource for the rull list of pool options.

<br>> My comment: I have had a first look at ibatis 3 and I like it a lot. Even though annotations might not have lived up to the expected promise, we certainly have some use cases for which they are going to be very handy. Thanks for the good work guys!

<br>> My question: We have a new project we will be working on for the next 5-7 months and I want to start using ibatis 3 and ibator. Is there any ibator code for ibatis 3 in svn that can be checked out or any binaries for a current version of ibator that supports ibatis 3?

<div class="quote-message shrinkable-quote">Hi All,
<br><br>Please could someone assist, I know this might be a silly question with a simple answer but I have tried all examples I have found, I have read the documentation and I have searched the forums and the internet but to no avail.
<br><br>I am using the latest beta version of iBatis 3 (beta 5) but had the same problem with beta 4. In iBatis v2x these complex key mappings worked fine.
<br><br>The documentation states:
<br><br>"Note: To deal with composite keys, you can specify multiple column names
<br>to pass to the nested select statement by using the syntax column=”{prop1=col1,prop2=col2}”. This
<br>will cause prop1 and prop2 to be set against the parameter object for the target nested select statement."
<br><br>However when I specify this with multiple columns for a collection the nested select is never run and no error is reported. In the referenced "select" I am accessing the parameters by #{param1Name} and #{param2Name} (where param1Name is the name of the first param etc..).
<br><br>If I remove this and only specify one parameter like column="col_1" then the referenced "select" is executed and the same param is used for both parameter mapping in the select. So the collection mapping can access the nested select and return a list of the correct type (albeit with a lot of incorrect rows due to not matching on the full complex key) but not when I have complex keys specified.
<br><br>What is the correct notation for using multiple columns for complex keys from a "collection" mapping. There are no examples in the documentation other than the excerpt above. I have also not found any workable examples on the internet.
<br><br>I have found references on the internet to accesing params with @{param} instead of #{param} which I have also tried with no luck. I have also tried specifying paramaterType="map" on the nested select with no results.
<br><br>ResultMap (XML file 1):
<br><resultMap id="myResultMap" type="ResultClass">
<br> <id property="id" column="id" />
<br> <id property="clientId" column="client_id" />
<br> <result property="someProp" column="some_prop" />
<br> <collection property="myList" column="{id=id,clientId=client_id}" javaType="ArrayList" ofType="MyType" select="other.xml.namespace.MyTypeNS.nestedSelect" />
<br></resultMap>
<br><br>Select (XML file 2):
<br><mapper namespace="other.xml.namespace.MyTypeNS">
<br> <resultMap id="myTypeResultMap" type="MyType">
<br> <!-- mapping of MyType -->
<br> </resultMap>
<br> <select id="nestedSelect" parameterType="map" resultMap="myTypeResultMap">
<br> SELECT *
<br> FROM my_type_table
<br> WHERE other_id = #{id} AND client_id = #{client_id}
<br> </select>
<br></mapper>
<br><br>Thanks for your time.

However, I do see a problem with the license and being able to just drop it in the source for iBatis as its currently licensed. It could be wrapped as a third-party dll and reference that was as we currently do with the Castle dll's. But that would bring the number of DLL's up to 5<br>

<br><br>Please could someone assist, I know this might be a silly question with a simple answer but I have tried all examples I have found, I have read the documentation and I have searched the forums and the internet but to no avail.
<br><br>I am using the latest beta version of iBatis 3 (beta 5) but had the same problem with beta 4. In iBatis v2x these complex key mappings worked fine.
<br><br>The documentation states:
<br><br>"Note: To deal with composite keys, you can specify multiple column names
<br>to pass to the nested select statement by using the syntax column=”{prop1=col1,prop2=col2}”. This
<br>will cause prop1 and prop2 to be set against the parameter object for the target nested select statement."
<br><br>However when I specify this with multiple columns for a collection the nested select is never run and no error is reported. In the referenced "select" I am accessing the parameters by #{param1Name} and #{param2Name} (where param1Name is the name of the first param etc..).
<br><br>If I remove this and only specify one parameter like column="col_1" then the referenced "select" is executed and the same param is used for both parameter mapping in the select. So the collection mapping can access the nested select and return a list of the correct type (albeit with a lot of incorrect rows due to not matching on the full complex key) but not when I have complex keys specified.
<br><br>What is the correct notation for using multiple columns for complex keys from a "collection" mapping. There are no examples in the documentation other than the excerpt above. I have also not found any workable examples on the internet.
<br><br>I have found references on the internet to accesing params with @{param} instead of #{param} which I have also tried with no luck. I have also tried specifying paramaterType="map" on the nested select with no results.
<br><br>ResultMap (XML file 1):
<br><resultMap id="myResultMap" type="ResultClass">
<br> <id property="id" column="id" />
<br> <id property="clientId" column="client_id" />
<br> <result property="someProp" column="some_prop" />
<br> <collection property="myList" column="{id=id,clientId=client_id}" javaType="ArrayList" ofType="MyType" select="other.xml.namespace.MyTypeNS.nestedSelect" />
<br></resultMap>
<br><br>Select (XML file 2):
<br><mapper namespace="other.xml.namespace.MyTypeNS">
<br> <resultMap id="myTypeResultMap" type="MyType">
<br> <!-- mapping of MyType -->
<br> </resultMap>
<br> <select id="nestedSelect" parameterType="map" resultMap="myTypeResultMap">
<br> SELECT *
<br> FROM my_type_table
<br> WHERE other_id = #{id} AND client_id = #{client_id}
<br> </select>
<br></mapper>
<br><br>Thanks for your time.

<br><br>In ADO.NET there is no simple way to do batch statement in a db provider independent manner as in JBDC.
<br><br>For now, I haven't think of a good solution to implement batch support in iBATIS.NET.
<br>Perhaps other people have some ideas ?
<br><br>If you use SQL Server you do that with a store procedure and an XML in parameter.

<br><br>My comment: I have had a first look at ibatis 3 and I like it a lot. Even though annotations might not have lived up to the expected promise, we certainly have some use cases for which they are going to be very handy. Thanks for the good work guys! (I can soon retire my custom auto generated keys hack for ibatis 2)
<br><br>My question: We have a new project we will be working on for the next 5-7 months and I want to start using ibatis 3 and ibator. Is there any ibator code for ibatis 3 in svn that can be checked out or any binaries for a current version of ibator that supports ibatis 3?
<br><br>thanks

<br>Count returns a number. That number might be 0 or any other non-negative integer.
<br>AFAIK java doesn't do the 0 = false, non-zero = true conversion you have in C/C++.
