Hi Guys,

I have a published server.

Where i'm write a function which returns a table using Exec query.

But Unfortunately i'm getting error

Msg 443, Level 16, State 14, Procedure Fn_GetDailyRentalFullDataForView, Line 15
Invalid use of a side-effecting operator 'INSERT EXEC' within a function.

Msg 444, Level 16, State 2, Procedure Fn_GetDailyRentalFullDataForView, Line 18
Select statements included within a function cannot return data to a client.

Msg 455, Level 16, State 2, Procedure Fn_GetDailyRentalFullDataForView, Line 18
The last statement included within a function must be a return statement.

What I have tried:

Create Function Fn_GetDailyRentalFullDataForView()
Returns  @t table(
					[VehicleType] [int] NULL,
					[vt] [nvarchar](50) NULL,
					[TruckTotal] [nvarchar](50) NULL,
					[Description] [nvarchar](max) NULL,
					[Driver] [nvarchar](50) NULL,
					[Location] [nvarchar](250) NULL,
					[Department] [nvarchar](50) NULL,
					[JobDate] [date] NULL
				)

as
begin
insert into @t				
exec Sp_GetDailyRentalFullDataForView

select * from @t
end

This is my Function.

Please let me know, where i'm getting wrong.

Thanks

This code is illegal as you cannot execute stored procedure from a function (read the documentation[^]):

SQL

insert into @t				
exec Sp_GetDailyRentalFullDataForView

You must also return results via return not select:

SQL

Create Function Fn_GetDailyRentalFullDataForView()
Returns  @t table(...)
as
begin
-- populate @t 
return
end
