Question

如果fromloc = 1，我想从ReceiveNote中选择，然后打印工厂，否则必须打印其他

SELECT PurDate,
case ReceiveNote.FromLOC
when ReceiveNote.FromLOC = '1' THEN 'Factory'
when ReceiveNote.FromLOC = '2' THEN 'Other'
else ''
end as FromLOC FROM tbl1

Answer 1

您已在CASE字后指定了字段。无需再次指定。

SELECT PurDate,
       CASE ReceiveNote.FromLOC
            WHEN '1' THEN 'Factory'
            WHEN '2' THEN 'Other'
            ELSE ''
       END AS FromLOC 
  FROM tbl1

here is documentation on CASE for tsql

Answer 2

SELECT PurDate,
case when ReceiveNote.FromLOC = '1' THEN 'Factory'
when ReceiveNote.FromLOC = '2' THEN 'Other'
else ''
end as FromLOC FROM tbl1
