Dataworks-数据服务之API脚本模式(高级SQL)
常用的高级SQL示例:
1、通过判断字段值是否为空来控制where查询条件是否保留
<where> <if test='PUR_ODR_CODE !=null and PUR_ODR_CODE !=""'> AND PUR_ODR_CODE=${PUR_ODR_CODE} </if> <if test='PUR_ODR_ITEM_CODE !=null and PUR_ODR_ITEM_CODE !=""'> AND PUR_ODR_ITEM_CODE=${PUR_ODR_ITEM_CODE} </if> </where>
2、IN 多值遍历
<where> <if test='UTC_NUM!=null'> and UTC_NUM in <foreach collection="UTC_NUM" open="(" close=")" separator="," item="utc_num"> ${utc_num} </foreach> </if> </where>
参数需要选择: STRING_LIST
3、Like模糊匹配
<where> <if test='WBS_CODE !=null and WBS_CODE !=""'> AND WBS_CODE like concat('%',${WBS_CODE},'%') </if> <if test='SUPP_NAME !=null and SUPP_NAME !=""'> AND SUPP_NAME like concat('%',${SUPP_NAME},'%') </if> </where>
4、对日期或者数值进行范围查询
<where> <if test='ACT_DLV_TIME_START !=null and ACT_DLV_TIME_START !=""'> AND ACT_DLV_TIME >= ${ACT_DLV_TIME_START} </if> <if test='ACT_DLV_TIME_END !=null and ACT_DLV_TIME_END !=""'> AND ACT_DLV_TIME <= ${ACT_DLV_TIME_END} </if> </where>
