mybatis return primitive type for procedure call

Question

I want to return primitive type after call oracle procedure, here is my mybatis interface:

public interface ProcedureMapper {
    int getProcedureResult();
}

I want to execute a procedure or function then return status, I tried the config bellow:

<select id="getProcedureResult" statementType="CALLABLE" resultType="int">
        BEGIN   
           EXECUTE IMMEDIATE 'CREATE TABLE temp_tt (id NUMBER(12) )';
           #{status,mode=OUT,jdbcType=INTEGER} := 0;
        EXCEPTION
           WHEN OTHERS THEN 
           #{status,mode=OUT,jdbcType=INTEGER} := -1;
        END;
</select>

doesn't work, will throw the Exception:

Caused by: org.apache.ibatis.reflection.ReflectionException: Could not set property 'status' of 'class java.lang.Class' with value 'null' Cause: org.apache.ibatis.reflection.ReflectionException: There is no setter for property named 'status' in 'class java.lang.Class'

I know I can set resultType to Java Bean with 'status' property inside, but I just want to return primitive type not java bean, any ideas?

Answer 1

write your procedure like this in string -

public String proc = "BEGIN\n"
+"\tEXECUTE IMMEDIATE 'CREATE TABLE temp_tt (id NUMBER(12) )';\n"
+"\tstatus := 0;\n"
+"\tEXCEPTION\n"
+"\t\tWHEN OTHERS THEN\n" 
+"\tstatus := 0;\n"
+"\tEND;\n"

and execute below statement in your java code insted where you are calling that procuder in mybatis

session.getConnection().prepareCall(String.format(proc)).execute();

ANOTHER SOLUTION IS:

another solution is create a your procedure in database and save it. and call it from mybatis

<update id="getProcedureResult" statementType="CALLABLE">
    {call some_procedure(
     #{status, javaType=java.lang.Integer, jdbcType=INTEGER, mode=OUT})
    }
</update>
