1、table-valued function can join table, but Scalar-valued functions can not join table. SELECT*FROMTestCount(5) A,TestCount_1 BWHEREA.ID=B.ID 2、table-valued function can not nest in table, but Scalar-valued functions can do it. SELECTDBO.TestCount_SVF(5),*FROMTestCount_1 3、call ...
A scalar-valued function returns a single value. In SQL Server CLR integration, you can write scalar-valued user-defined functions in managed code.

hi, here is a demo version of the function and the sample call to it with output -- function used to get value for a key CREATE FUNCTION [dbo].[fn_ForDemo] (@mSettings NVARCHAR(1000), @mKey NVARCHAR(100)) RETURNS NVARCHAR(100) ...
A. Using an ODBC function in a stored procedure The following example uses an ODBC function in a stored procedure: SQL CREATEPROCEDUREdbo.ODBCprocedure ( @string_expNVARCHAR(4000) )ASSELECT{fnOCTET_LENGTH( @string_exp )}; B. Using an ODBC Function in a user-defined function ...
The function returns a single value each time it is invoked. A package is not created for an inlined SQL scalar function. The function is not invoked as part of a query; instead, the expression in the RETURN statement of the function is copied (inlined) into the query itself. ...
I think that we need a proper scalar function that will return the first column of the first row in the result set returned by the query, just likehttps://learn.microsoft.com/en-us/dotnet/api/system.data.sqlclient.sqlcommand.executescalar?view=dotnet-plat-ext-8.0 ...
