当计数为0时，更新为0不显示空

Question

我正在运行此更新查询，我希望它会更新表以保持值为0而不是在计数为0时显示NULL。如何更新以强制表，因此在显示时显示0返回的计数是0？

set @sql = 
  'UPDATE cra
  SET mastercounts = te.LC
  FROM #tbl_test As cra
  JOIN (
        select 
        ,COUNT(CASE WHEN recordID < 1 THEN 0 ELSE recordID end) As LC
        ,employeename
        from productioninformaiton
        where salestatus = (''Approved'', ''Shipped'')
        Group By employeename
  ) As te 
  ON cra.[StoreName] = te.[StoreName]
  AND cra.[employeename] = te.[employeename]'
Exec (@sql)

Answer 1

也许是字段＆＃34; recordID＆＃34;在某些情况下返回NULL，这使得COUNT（NULL）也返回NULL。尝试替换

COUNT(CASE WHEN recordID < 1 THEN 0 ELSE recordID end) As LC

带

COUNT(CASE WHEN ISNULL(recordID, 0) < 1 THEN 0 ELSE ISNULL(recordID, 0) end) As LC
