I tested it and it doesn't works for me.
This works great now:
@Select({"SELECT * FROM send LIMIT #{offset}, #{limit}"})
List<Send> getAllItems(@Param("offset") int offset, @Param("limit") int
limit);
but this not:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd";>
<mapper namespace="cz.apache.ibatis.SendMapper">
<select id="getAllItemsX" parameterType="map"
resultType="cz.apache.ibatis.Send" >
select * from send LIMIT #{offset}, #{limit}
</select>
</mapper>
I got:
Exception in thread "main" org.apache.ibatis.exceptions.IbatisException:
### Error querying database. Cause: org.apache.ibatis.type.TypeException: JDBC
requires that the JdbcType must be specified for all nullable parameters.
### The error may exist in SendMapper.xml
### The error may involve cz.apache.ibatis.SendMapper.getAllItemsX-Inline
### The error occurred while setting parameters
### SQL: select * from send LIMIT ?, ?
### Cause: org.apache.ibatis.type.TypeException: JDBC requires that the
JdbcType must be specified for all nullable parameters.
at
org.apache.ibatis.exceptions.ExceptionFactory.wrapException(ExceptionFactory.java:8)
How Can I specify parametr types?
