Why Does My Stored Procedure Get a 'Too Many Arguments Specified' Error?

Too Many Arguments Specified in Stored Procedures

Problem:

When executing a stored procedure that calls another stored procedure, you may encounter the error message "Procedure or function has too many arguments specified." This error indicates a mismatch between the number of arguments passed to the called procedure and the number of arguments it is declared to accept.

Identification:

To identify the erroneous arguments, examine the parameters declared in the called procedure's definition. Compare these parameters to the arguments passed from the calling procedure. The mismatch will identify where the excess arguments are.

Analysis of Provided Code:

In the given code snippet, the error occurs because you are calling the stored procedure [etl_M_Update_Promo] with two arguments:

EXEC etl.etl_M_Update_Promo @GenID, @Description

However, the definition of [etl_M_Update_Promo] declares only one argument:

ALTER PROCEDURE [etl].[etl_M_Update_Promo]
    @GenId bigint = 0

Therefore, SQL Server throws the error message, indicating that the called procedure is expecting one argument, while it is being passed two.

Resolution:

To resolve the issue, align the number of arguments passed to the called procedure with the number it expects. In this case, you have two options:

1. Remove the Excess Argument:
   Modify the code in [dbo].[M_UPDATES] to remove the second argument:

   EXEC etl.etl_M_Update_Promo @GenID

2. Add the Missing Parameter:
   Alter the definition of [etl_M_Update_Promo] to include the second parameter:

   ALTER PROCEDURE [etl].[etl_M_Update_Promo]
       @GenId bigint = 0,
       @Description NVARCHAR(50)
   AS 
   
   .... Rest of the code.
