The data type cast is needed only null values are passed to JDBC driver.
Because in the Spring, you got to tell what the driver expect to do if a
null value set to input. And Spring tries to use same code for different
DB drivers, there is no way to use diffrent data type with null values
for all kinds of DB drivers.

Henry,
Yes, they are usually smart enough for casting to the appropriate
type. But it's not good to rely on this every time you need to do
something like Jason is. Type casts can make harder to figure out some
errors.
Jason, let me know if using Oracle's driver worked for you.
Cheers,
Daniel Silva.

This works, but doesn't makes sense why since my column is a NUMBER data type.
Does JDBC-ODBC driver be the problem on Oracle 9i?

Change NUMBER to varchar will take care the business.
<parameterMap id="paramMap" class="ca.cihi.omhrs.Dummy" >
<parameter property="id" jdbcType="VARCHAR" nullValue="-999" />
<parameter property="name" jdbcType="VARCHAR" nullValue="NO_ENTRY" />

Hi Jason,
Looking at the stack trace you posted, it's clear that the error
you're getting comes from your DB.
Look at your table Dummy structure. Does it allow the column id to be null?
Also, what is your DB?
Hope that helped.
Cheers,
Daniel Silva.

Hi,
I'm trying to force a null in a nullable column and i get an error.
Java code:
Dummy d = new Dummy();
d.setId(-999);
sqlMap.insert("Dummy.insertDummy",d);
Sql Map:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-2.dtd";>

<parameterMap id="paramMap" class="ca.cihi.omhrs.Dummy" >
<parameter property="id" jdbcType="NUMBER" nullValue="-999" />
<parameter property="name" jdbcType="VARCHAR" nullValue="NO_ENTRY" />
</parameterMap>
<insert id="insertDummy" parameterMap="paramMap">
insert into Dummy(id,name)
values(?,?)
</insert>
<!--
<insert id="insertDummy" parameterClass="ca.cihi.omhrs.Dummy">
insert into Dummy(id,name)
values(#id:NUMERIC:#,#name:VARCHAR:NO_ENTRY#)
</insert>
-->
</sqlMap>
I get the following error:
