Re: How to get both of return value and return result
It is still not working. I simplify the code to avoid the nested result
map, after that I still can not get the result set back. Here is my latest
code:
1. Parameter Map:
<parameterMap id="globalParameter" class="java.util.HashMap" >
<parameter property="pReturnCode" jdbcType="INTEGER"
javaType="java.lang.Integer" mode="OUT"/>
<parameter property="pUSERID" jdbcType="INTEGER" javaType=
"java.lang.Integer" mode="IN"/>
</parameterMap>
2. Result Map:
<typeAlias type="testComplexCollection.Model.FlatUserProfile"
alias="flatUserProfile"/>
<resultMap class="flatUserProfile" id="flatUserProfileResult">
<result property="userID" column="UserID"/>
<result property="userName" column="UserName"/>
<result property="groupName" column="UserGroupName"/>
</resultMap>
3. Procedure Map:
<procedure id="getFlatUserProfile" parameterMap="globalParameter"
resultMap="flatUserProfileResult">
{? = call HILLXIE.TEST_GETUSERSBYID (?)}
</procedure>
4. DAO Code:
HashMap parameters = new HashMap();
Integer returnCode = new Integer(-1);
parameters.put("pReturnCode", returnCode);
parameters.put("pUserID", new Integer(userID));
FlatUserProfile flatUserProfile =
(FlatUserProfile)getSqlMapClientTemplate().queryForObject(
"getFlatUserProfile", parameters);
5. Stored procedure:
DECLARE DB2_SP_SQL1 CURSOR WITH RETURN FOR
Select UserID, UserName, UserGroupName FROM USERS WHERE
UserID = pUserID;
OPEN DB2_SP_SQL1;
RETURN 100;
6. Model:
package testComplexCollection.Model;
import java.lang.String;
public class FlatUserProfile {
private int userID;
private String userName;
private String groupName;
public String getGroupName() {
return groupName;
}
public void setGroupName(String groupName) {
this.groupName = groupName;
}
public int getUserID() {
return userID;
}
public void setUserID(int userID) {
this.userID = userID;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
It looks like a bug for me, any help would be highly appreciated.

Re: How to get both of return value and return result
Thank you for reply. I am using nested result map. The result map works
well if the return value is not checked. For example if the syntax of the
callable statement is:
{call TEST_GETUSERSBYID (?)}
Then the result set can be mapped to the object without problem. I will
try your scenario (using output parameter instead of return value) to see
if it works for me. Maybe I should also try not to use the nested result
map too.

This should be supported. I just ran a quick test with MySql and
everything was OK (a SP with OUT parameters and a result set). This is
not exactly your scenario, but the idea is the same.
You did not share your result map - so it's hard to tell if there might be
a problem there or not. There is a known bug if you're using only nested
result maps, or in certain circumstances where there are nulls in the
result set.

Hi,
I am very sorry to repost this, because my original thread was occupied.
Here is my problem:
I have a DB2 stored procedure returns a single value and a result set at
the same time, like this:
DECLARE DB2_SP_SQL1 CURSOR WITH RETURN FOR
Select * FROM USERS WHERE UserID = pUserID;
OPEN DB2_SP_SQL1;
RETURN 100;
I tried many times, I can only get the return value (100) back, while the
return result set is always empty. Here is the iBatis configuration and
java code:
1. iBatis Configuration:
<parameterMap id= "parameter" class="java.util.HashMap" >
<parameter property="pReturnCode" jdbcType="INTEGER"
javaType ="java.lang.Integer" mode= "OUT"/>
<parameter property= "pUSERID" jdbcType="INTEGER" javaType=
"java.lang.Integer" mode ="IN"/>
</parameterMap>
<procedure id ="getUserProfile" parameterMap= "parameter"
resultMap="userProfileResult" >
{? = call TEST_GETUSERSBYID (?)}
</procedure>
2. Java Code:
HashMap parameters = new HashMap();
Integer returnCode = new Integer(-1);
parameters.put("ReturnCode", returnCode);
parameters.put("UserID", new Integer(userID));
UserProfile userProfile =
(UserProfile)getSqlMapClientTemplate().queryForObject("getUserProfile",
parameters);
3. Result: userProfile is null, the ReturnCode in the HashMap is 100.
After I debugged into the iBatis code, I found the code does populate some
data (I am not sure what data it is) into the resultset object. But
rs.next()returns false, so the code ignores the resultset and doesn't do
any mapping for the result set.
Is it unsupported by iBatis?
Thanks,
