Hi,

I'd like to use an SP output to assign it to a variable of another SP Like here, I want to output of the GetLinage SP be assigned to @linage in InsertLog SP, But an error I get is that,

SQL

Procedure or function GetLinage has too many arguments specified.

I Don't know if what I'm mistaking,

SQL

EXEC InsertLog 'MenuItem78', 'thisrout', 'thisbutton', '2000-01-01 00:00:00' , 123

ALTER PROCEDURE 
InsertLog(
	@formName nvarchar,
	@buttonRout nvarchar,
	@buttonName nvarchar,
	@clickDateTime DateTime,
	@userCode bigint
	)

AS
BEGIN

DECLARE
@linage nvarchar
EXEC GetLinage @formName, @linage  OUTPUT



INSERT INTO 
LogTable(
	FormName,
	Linage,
	ButtonRout,
	ButtonName,
	ClickDateTime,
	UserCode
	)
VALUES(
	@formName,
	@linage,
	@buttonRout,
	@buttonName,
	@clickDateTime,
	@userCode
	)

END
GO

The GetLinage SP is as follows:

SQL

CREATE PROCEDURE GetLinage (@formname nvarchar)
AS

SELECT Linage
FROM formslist
WHERE (formslist.Formname = @formname)


GO

What I have tried:

I'm working on it and other different ways for it. but yet know answer.

Hi,

You don't return a value from your 2nd procedure.
Try modifying it to something like:

SQL

ALTER PROCEDURE GetLinage (
    @formname nvarchar,
    @linage  nvarchar OUTPUT
)
AS
 
SELECT @linage = Linage
FROM formslist
WHERE (formslist.Formname = @formname)

GO

... hope it helps.

Check below Solution. So you don't have to change logic in inner SP.

Note: This solution will work only if
1. inner SP not contain below statement
2. It will give value of 1 row only, even SP returns multiple rows.

SQL

Insert Into #Table
EXEC ....

Script:

SQL

Alter PROCEDURE InsertLog
(
	@formName nvarchar,
	@buttonRout nvarchar,
	@buttonName nvarchar,
	@clickDateTime DateTime,
	@userCode bigint
)
 
AS
BEGIN
 
DECLARE @linage nvarchar(30)
Create Table #Result (linage nvarchar(30))

Insert Into #Result
EXEC #GetLinage @formName--, @linage  OUTPUT
 
Select @linage = linage From #Result

INSERT INTO 
LogTable(
	FormName,
	Linage,
	ButtonRout,
	ButtonName,
	ClickDateTime,
	UserCode
	)
Select	@FormName, @Linage, @ButtonRout, @ButtonName, @ClickDateTime, @UserCode
