The SQL Server (2000/2005) function gets the table name and the field name as parameters and returns results from a dynamic query within the function. The results should be assigned to a Table
variable which will be used further in a stored procedure. How to achieve this?
I am getting error: "Only functions and extended stored procedures can be executed from within a function."
Declare @Data as table (FieldValue varchar(100))
insert into @Data select * from MyFunction ('Person.Address','AddressID')
-- Function
Alter function MyFunction (
@TableName varchar(100), @FieldName varchar(100)
) returns @GetData table (
FieldValue varchar(100)
) as
begin
Declare @SQL varchar(250)
Set @SQL = 'Select '+@FieldName+ ' from '+ @TableName
Exec sp_executesql @SQL
return
end
just to close the loop...
here is the syntax for calling the function and putting those results in a table variable
small build on @simons solution
this ran on sql2012 and sql2014.
[ dont forget to close off the table statement. Easy enough to do if you have the table all on a single line. ]
declare @t table(field1 nvarchar(100) )
insert @t select * from dbo.Cool_1Field_Function( 'parm1' ,'parm2')
select * from @t
