Question

我需要你们帮助我完成任务。

1

SELECT * FROM DBMGR.RTREDC00
WHERE EDC_PARM = '9940-RESOE'
AND EDC_LOT = 'H28BRAD'` 

2

SELECT LSPEC.GET_LSPEC_MIN((SELECT RL_PO FROM DBMGR.RTRLOT01 WHERE 
    RL_FACILITY = 'MKLPROD' AND RL_LOT = 'H28BRAD'),'9940-RES','M') MIN_RAS,
    LSPEC.GET_LSPEC_MAX((SELECT RL_PO FROM DBMGR.RTRLOT01 WHERE RL_FACILITY 
    = 'MKLPROD' AND RL_LOT = 'H28BRAD'),'9940-RES','M') MAX_RAS
    FROM DUAL

我需要使用CASE WHEN创建语法，edc_value和MIN_RAS之间的MAX_RAS输出将为空，如果edc_value不在MIN_RAS之间{1}}和MAX_RAS输出将为edc_lot。

我相信这就是你要找的东西。
