Hi all,

DECLARE @batchSize INT
Declare @siteid nchar(3)
DECLARE @Instanceid nchar(3)


set @siteid = '002'
SET @InstanceId = '001'

SELECT @batchSize = CAST(ConfigurationValue AS Int)
from ApplicationConfiguration
where ConfigurationDescription='SyncBatchSize' and InstanceId = @InstanceID and SiteiD = @SIteID

select @batchsize
-- Result NULL

SELECT @batchSize = CAST(ConfigurationValue AS Int)
from ApplicationConfiguration
where ConfigurationDescription='SyncBatchSize' and InstanceId = '001' and SiteiD = '002'

select @batchsize
-- Result 501

While passing variable I am gettign NULL in result while when I pass static value then it gives me result as 501, why this is happening...

Maybe because you switched values in your example.

With DDL for TABLE ApplicationConfiguration, specifically data types for InstanceId and SiteiD, someone might be able to propose a hypothesis.


My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.


Need to UNPIVOT? Why not CROSS APPLY VALUES instead?
