SQL Stored Procedure to Generate Sequential Number

Microsoft SQL ServerWhile much of the work I do is directly with Microsoft Dynamics GP, I also do work for clients which isn’t directly related. I’ve created code to generate numbers a few times in the past and figured I might as well post the base code I use for this to make it easier to find in future.

I’ve created it in such a way that several unique numbers can be stored and incremented.

The first part of the code creates a table to hold the number type and next number:

-- drop table if it exists
IF OBJECT_ID (N'ut_AZRCRV_NextNumber', N'U') IS NOT NULL
	DROP TABLE ut_AZRCRV_NextNumber
GO
-- create table
CREATE TABLE ut_AZRCRV_NextNumber(
	NMBRTYPE VARCHAR(50)
	,NEXTNMBR INT
)
GO

Next, I create a stored procedure which will increment and return the next number:

-- drop stored proc if it exists
IF OBJECT_ID (N'usp_AZRCRV_GetNextNumber', N'P') IS NOT NULL
    DROP PROCEDURE usp_AZRCRV_GetNextNumber
GO
-- create stored proc
CREATE PROCEDURE [dbo].[usp_AZRCRV_GetNextNumber]
	(
	@NMBRTYPE VARCHAR(50)
	,@NEXTNMBR INT OUTPUT
	)
AS

SET NOCOUNT ON BEGIN TRAN -- if this is the first value generated for this table, start with one IF NOT EXISTS (SELECT * FROM ut_AZRCRV_NextNumber WHERE NMBRTYPE = @NMBRTYPE) INSERT INTO ut_AZRCRV_NextNumber (NMBRTYPE,NEXTNMBR) VALUES (@NMBRTYPE,1) -- select next number from table into variable SELECT @NEXTNMBR = NEXTNMBR FROM ut_AZRCRV_NextNumber WHERE NMBRTYPE = @NMBRTYPE -- increment number by 1 UPDATE ut_AZRCRV_NextNumber SET NEXTNMBR = NEXTNMBR + 1 WHERE NMBRTYPE = @NMBRTYPE COMMIT TRAN -- return variable containing next number RETURN @NEXTNMBR GO

Then, I grant execute permissions to the relevant database role:

-- grant execute permission on stored proc to ur_AZRCRV_InvoiceUser
GRANT EXECUTE ON usp_AZRCRV_GetNextNumber TO ur_AZRCRV_InvoiceUser
GO

And finally, I have the SQL code which will generate the next number:

-- code to get next number
DECLARE @NMBRTYPE VARCHAR(50) = 'Sales Invoice'
DECLARE @NEXTNMBR INT

EXEC [usp_AZRCRV_GetNextNumber] @NMBRTYPE, @NEXTNMBR OUTPUT

SELECT @NEXTNMBR
GO

SQL Stored Procedure to Remove Prior Day Logins

Microsoft Dynamics GPIn the last post, I posted a SQL view which returned a list of users who had logged in before the current date. This post contains a SQL stored procedure which will delete any prior day login; this could be scheduled to run using SQL Server Agent:

CREATE PROCEDURE usp_AZRCRV_RemovePriorDayLogins AS
/*

*/
	DELETE FROM
		ACTIVITY
	WHERE
		['User Activity'].LOGINDAT <= DATEADD(DAY, -1, GETDATE())
GO
GRANT EXECUTE ONusp_AZRCRV_RemovePriorDayLogins TO DYNGRP
GO

Before using this script on a live system, I’d recommend testing it on a standalone test system first.

Stored Procedure To Get Next Purchase Receipt Number

Microsoft Dynamics GPThis stored procedure can be executed to generate the next sequential purchase receipt number which can be used for both receivings transactions (Shipment and Shipment/Invoice) and invoices; the generated invoice was then added to the integration file which was then submitted to eConnect. I’ve written this stored procedure at least three times for different integrations, so thought it best to post it here so I don’t write it again.

-- drop stored proc if it exists
IF OBJECT_ID (N'usp_AZRCRV_GetNextPOPReceiptNumber', N'P') IS NOT NULL
    DROP PROCEDURE usp_AZRCRV_GetNextPOPReceiptNumber
GO
-- create stored proc
CREATE PROCEDURE usp_AZRCRV_GetNextPOPReceiptNumber AS

BEGIN
	DECLARE @return_value INT
	DECLARE @I_vInc_Dec TINYINT = 1
	DECLARE @O_vPOPRCTNM AS VARCHAR(17)
	DECLARE @O_iErrorState INT

	exec @return_value = taGetPurchReceiptNextNumber  @I_vInc_Dec, @O_vPOPRCTNM = @O_vPOPRCTNM OUTPUT,  @O_iErrorState = @O_iErrorState OUTPUT
	SELECT @O_vPOPRCTNM
END
GO

-- grant execute permission on stored proc to DYNGRP
GRANT EXECUTE ON usp_AZRCRV_GetNextPOPReceiptNumber TO DYNGRP
GO

-- execute stored proc
EXEC usp_AZRCRV_GetNextPOPReceiptNumber
GO

The stored proc calls a Microsoft Dynamics GP stored procedure which actually does the work, so we are still getting the receipt number using standard functionality.
