Hi,
I have table with columns like CustomerName, CustomerAddress, CreatedDate, ImplementationDate, Revenue1, Revenue2, .............................Revenue15.
Here CustomerName, CustomerAddress - varchar(2000)
CreateDate, ImplementationDate -DateTime
All Revenue1... 15 columns are Numeric(38,2)
In a procedure, I am using Order by clause with case statement for all these columns
Like
Select * from Customer_Repo
Order By Case @OrderColumn
When 'CustomerName' Then CustomerName
When 'CustomerAddress' Then CustomerAddress
When 'CreatedDate' Then CreatedDate
When 'ImplementationDate' Then ImplementationDate
When 'Revenue1' Then Revenue1
When 'Revenue15' Then Revenue15
END
But the order by clause different datatypes, I am getting some error.
Can anyone help me on this to resolve ?
Thanks,
Peer Md.

Go with the followinf case statement...

Select * from Customer_Repo

Order By

Case When @OrderColumn='CustomerName' Then CustomerName End,

Case When @OrderColumn='CustomerAddress' Then CustomerAddress End,

Case When @OrderColumn='CreatedDate' Then CreatedDate End,

Case When @OrderColumn='ImplementationDate' Then ImplementationDate End,

Case When @OrderColumn='Revenue1' Then Revenue1 End,

Case When @OrderColumn='Revenue15' Then Revenue15 End

Did Atif's solution work?

What is the error?

You could do an explicit convert to character(varchar) on the numeric columns.

Just tossing this out there, no idea if it's related. Does SQL treat large varchars as text? If so, I wouldn't think you could 'order by' because SQL won't compare 'text' types.

P.S. That is a question. When, if at all, does SQL treat char/varchar as a text type.

No SQL Server does not treat large varchars as text.
