Cannot find either column “dbo” or the user-defined function or aggregate “dbo.Splitfn”, or the name is ambiguous

Question

Hai guys,

I ve used the following split function,

CREATE FUNCTION dbo.Splitfn(@String varchar(8000), @Delimiter char(1))       
returns @temptable TA         


        

Answer 1

It's a table-valued function, but you're using it as a scalar function.

Try:

where Emp_Id IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)

But... also consider changing your function into an inline TVF, as it'll perform better.

Answer 2

You need to treat a table valued udf like a table, eg JOIN it

select Emp_Id 
from Employee E JOIN dbo.Splitfn(@Id,',') CSV ON E.Emp_Id = CSV.items 

Answer 3

A general answer

select * from [dbo].[SplitString]('1,2',',') -- Will work 

but

select [dbo].[SplitString]('1,2',',')  -- will not work and throws this error

Answer 4

Since people will be coming from Google, make sure you're in the right database.

Running SQL in the 'master' database will often return this error.
