MyBatis calls stored procedure

mybatis call stored procedure

The syntax for calling a stored procedure in JDBC is as follows. Note that square brackets indicate that the content between them is optional; the square brackets themselves are not part of the syntax. 

{call procedure_name[(?, ?, ...)]} 

The syntax for a procedure that returns a result parameter is: 

{? = call procedure_name[(?, ?, ...)]} 

a stored procedure with no parameters The syntax is similar: 

{call procedure name} 

 

XML configuration with return value

<select id="getReturnCount" parameterType="java.util.Map" statementType="CALLABLE">
        <![CDATA[
           {#{cityCount,mode=OUT,jdbcType=INTEGER}=call dbo.p_logic_test_web(
              #{cityId,mode=IN,jdbcType=INTEGER}
           )}    
       ]]>
    </select>

 The returned result is a Map, which takes the value directly from the key= cityCount in the map
