<select id="keyEquipmentShiftAutomatedModelData" parameterType="java.util.Map" resultType="java.util.Map"> SELECT ID, SUM(VALUE1 + VALUE2) Total FROM tableName GROUP BY ID </select>
Returns below result in sql
ID, Total
1 (null)
But when returned in Map result in myBatis returns {ID=1} where as Total is missing. How to get the column with null into the result set as well something like this {ID=1,Total=null} or something like this {ID=1,Total=""}
