两查询结果相加后没有数据了。
------解决方案--------------------
- SQL code
SELECT TOP 1 SUM(QTY) FROM MRT WHERE JOBNO=RESVT.JOBNO AND MRT.CODE=RESVT.CODE AND P_CODE=RESVT.P_CODE
- SQL code
SELECT TOP 1 SUM(KT.QTY)
FROM KT INNER JOIN KTUDF ON(KT.ITEMNO=KTUDF.ITEMNO AND KT.KINNO=KTUDF.KINNO)
WHERE KT.KTYPE='02' AND KTUDF.GDH=(CASE WHEN MASTERJOB = '' THEN JOBNO ELSE MASTERJOB END) AND KT.CODE=RESVT.CODE
- SQL code
select sum(n.col1+m.col1) col
from
(
SELECT TOP 1 SUM(QTY)col1 FROM MRT WHERE JOBNO=RESVT.JOBNO AND MRT.CODE=RESVT.CODE AND P_CODE=RESVT.P_CODE
)m,
(
SELECT TOP 1 SUM(KT.QTY)col1
FROM KT INNER JOIN KTUDF ON(KT.ITEMNO=KTUDF.ITEMNO AND KT.KINNO=KTUDF.KINNO)
WHERE KT.KTYPE='02' AND KTUDF.GDH=(CASE WHEN MASTERJOB = '' THEN JOBNO ELSE MASTERJOB END) AND KT.CODE=RESVT.CODE
)n
