Dear All,

Thank you for reading this...

I have query

SQL

SELECT  CONVERT(DECIMAL(18,3), ISNULL(CAST(60 AS DECIMAL(18,3))/CAST( 30 AS DECIMAL(18,3)),0))* 100 AS Efficiency
 FROM ProductionResultDisplyMst PRDM
 JOIN (SELECT PRDMID, SUM(Actual) Actual, SUM(Plans) Plans FROM ProductionResultDisplyDtls
   WHERE PRDMID IN (SELECT ID FROM ProductionResultDisplyMst WHERE PlantID=2
   AND StageID IN(2 ,3, 4, 5) AND shift=2)
   GROUP BY PRDMID ) PRDD
   ON PRDD.PRDMID = PRDM.ID
 JOIN StageMaster SM ON SM.StageID = PRDM.StageID
 WHERE PRDM.STAGEID IN (2,3, 4, 5)
 AND PRDM.PlantID = 2 AND PRDM.Shift = 2
 AND CONVERT(VARCHAR(10), PRDM.ProductionDate, 120) = CONVERT(VARCHAR(10), GETDATE(), 120)

For this Query I am getting the record as below

Efficiency
80
126
109
91

I want to change the Efficiency value as 100 if Efficiency >100
if Efficiency value less than 100, the same value will display.

ie,
Expected Result

Efficiency
80
100
100
91

How can i reach in this answer?...
Expecting your reply.

Thank you Aragon<code>,
A small difference from the above query
Remove "As E1" and "As E2"
ie,

SQL

SELECT CASE WHEN CONVERT(DECIMAL(18,3), ISNULL(CAST(60 AS DECIMAL(18,3))/CAST( 30 AS DECIMAL(18,3)),0))* 100  > 100 THEN 100 ELSE CONVERT(DECIMAL(18,3), ISNULL(CAST(60 AS DECIMAL(18,3))/CAST( 30 AS DECIMAL(18,3)),0))* 100  END AS Efficiency
 FROM ProductionResultDisplyMst PRDM
 JOIN (SELECT PRDMID, SUM(Actual) Actual, SUM(Plans) Plans FROM ProductionResultDisplyDtls
   WHERE PRDMID IN (SELECT ID FROM ProductionResultDisplyMst WHERE PlantID=2
   AND StageID IN(2 ,3, 4, 5) AND shift=2)
   GROUP BY PRDMID ) PRDD
   ON PRDD.PRDMID = PRDM.ID
 JOIN StageMaster SM ON SM.StageID = PRDM.StageID
 WHERE PRDM.STAGEID IN (2,3, 4, 5)
 AND PRDM.PlantID = 2 AND PRDM.Shift = 2
 AND CONVERT(VARCHAR(10), PRDM.ProductionDate, 120) = CONVERT(VARCHAR(10), GETDATE(), 120)

Thank you guys.........

Try out below solution with CASE statement in SQL.

SQL

SELECT CASE WHEN CONVERT(DECIMAL(18,3), ISNULL(CAST(60 AS DECIMAL(18,3))/CAST( 30 AS DECIMAL(18,3)),0))* 100 AS E1 > 100 THEN 100 ELSE CONVERT(DECIMAL(18,3), ISNULL(CAST(60 AS DECIMAL(18,3))/CAST( 30 AS DECIMAL(18,3)),0))* 100 AS E2 END AS Efficiency
 FROM ProductionResultDisplyMst PRDM
 JOIN (SELECT PRDMID, SUM(Actual) Actual, SUM(Plans) Plans FROM ProductionResultDisplyDtls
   WHERE PRDMID IN (SELECT ID FROM ProductionResultDisplyMst WHERE PlantID=2
   AND StageID IN(2 ,3, 4, 5) AND shift=2)
   GROUP BY PRDMID ) PRDD
   ON PRDD.PRDMID = PRDM.ID
 JOIN StageMaster SM ON SM.StageID = PRDM.StageID
 WHERE PRDM.STAGEID IN (2,3, 4, 5)
 AND PRDM.PlantID = 2 AND PRDM.Shift = 2
 AND CONVERT(VARCHAR(10), PRDM.ProductionDate, 120) = CONVERT(VARCHAR(10), GETDATE(), 120)

Hope it helps.
