I am trying to pass in startSequenceId, stopSequenceId, orderNumber into the SQL map, however, i don't wish to use a typed object, i.e. parameterType="com.abc.Order", can i do so?
<select id="getSequenceIdByOrderNumber" parameterType="?" resultType="int">
select *
from log
where seq_id
between #{startSequenceId} and #{stopSequenceId}
and order_no = #{orderNumber}
and rownum = 1
</select>
You can use the built in parameterType 'map' eg
Map<String, Object> parms = new HashMap<String, Object>();
parms.put("name", "abc");
parms.put("phone", "123");
parms.put("email", "123@email.com");
List<Contact> list = myBatis.selectList("getContacts",parms);
<!-- in xml mapper -->
<select id="getContacts" parameterType="map" resultMap="Contact">
SELECT * FROM CONTACT
WHERE CONTACT_NAME = ${name}
AND CONTACT_PHONE = ${phone}
AND CONTACT_MAIl = ${email}
</select>
@Chin I'll post what I had typed anyway with a simple example though you found what your looking for. My example using iBatis 2.3.4
<select id="retrieveTestXXX" parameterClass="java.util.Map" resultClass="java.lang.Integer">
SELECT
example_table.id
FROM example_table
WHERE example_table.xx_id = #testId# AND example_table.xx_id = #test2Id#
</select>
Hope this helps.
In MyBatis 3, you can use @Param annotation in your mapper class(interface) method:
public getSequenceIdByOrderNumber(@Param("seqId") int sequenceId,@Param("orderId") int orderNo);
Then you can use #{seqId}, #{orderId} in the SQL without using parameterType attribute.
cant comment,
Found the answer, thanks.

this link is broken, currently correct one is https://github.com/mybatis/mybatis-3/wiki/FAQ#how-do-i-use-multiple-parameters-in-a-mapper
Java reflection does not provide a way to know the name of a method parameter so MyBatis names them by default like: param1, param2... If you want to give them a name use the @param annotation this way:
import org.apache.ibatis.annotations.Param;
public interface UserMapper {
User selectUser(@Param("username") String username, @Param("hashedPassword") String hashedPassword);
}
Now you can use them in your xml like follows:
<select id=”selectUser” resultType=”User”>
select id, username, hashedPassword
from some_table
where username = #{username}
and hashedPassword = #{hashedPassword}
</select>
when you declare method in your interface instead of standard java structure
Type methodName (
ParamType1 paramName1,
ParamType2 paramName2,
… ); (this is interface so no method body)
use (add @Param)
Type methodName (
@Param("name1 available in xml") ParamType1 paramName1,
@Param("name2 available in xml") ParamType2 paramName2,
…); (this is still interface so no method body)
