Merge query in SQL Server stored procedure - sql

Question

I'll admit I don't have a lot of DB experience as my last job had a DBA but this place has none. I have an existing MASSIVE stored procedure that I need to modify (I noticed a lot of duplication and cut that out).
Right now, it pulls so much data they used a cache table or the page crashes. They just want a smaller amount of data now for a separate page. I'm trying to edit this stored procedure and merge in my new query to it.
The existing stored procedure:
ALTER PROCEDURE [dbo].[PurchasingSupplyChainNeeds]
(#maxAgeInHours INT = 24)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #sqlStmt NVARCHAR(max)
DECLARE #myName NVARCHAR(max) = Object_name(##PROCID)
DECLARE #needsRefresh INT
EXEC #needsRefresh = [cache].[NeedsRefresh]
#myName,
#maxAgeInHours
IF #needsRefresh = 1
BEGIN
DECLARE #CurrentMonth INT
DECLARE #DayOfWeek INT
DECLARE #EndOfWeekDate DATETIME
DECLARE #StartOfNextWeek DATETIME
DECLARE #WorkDaysInMonth INT
DECLARE #RunningDate DATE
DECLARE #WorkDaysLeftInMonth INT
DECLARE #DayOffset INT
SELECT #CurrentMonth = DATEPART(MONTH, GETDATE())
SELECT #DayOfWeek = DATEPART(WEEKDAY, GETDATE())
IF (#DayOfWeek = 1)
BEGIN
SET #StartOfNextWeek = GETDATE()
END
ELSE
BEGIN
SET #StartOfNextWeek = DATEADD(day, 8 - #DayOfWeek, GETDATE())
END
SELECT #DayOfWeek = DATEPART(weekday, GETDATE())
IF (#DayOfWeek = 7)
BEGIN
SET #EndOfWeekDate = Getdate()
END
ELSE
BEGIN
SET #EndOfWeekDate = DATEADD(day, -#DayOfWeek, GETDATE())
END
SET #WorkDaysInMonth = 0
SET #RunningDate = CONVERT(DATE, CONVERT(VARCHAR, #CurrentMonth) + '/1/' + CONVERT(VARCHAR, Datepart(year, Getdate())))
WHILE ( Datepart(month, #RunningDate) = #CurrentMonth )
BEGIN
SET #DayOfWeek = Datepart(weekday, #RunningDate)
IF ( #DayOfWeek != 1
AND #DayOfWeek != 7 )
BEGIN
SET #WorkDaysInMonth = #WorkDaysInMonth + 1
END
SET #RunningDate = Dateadd(day, 1, #RunningDate)
END
SET #WorkDaysLeftInMonth = 0
SET #DayOffset = 0
WHILE ( Datepart(month, Dateadd(day, #DayOffset, Getdate())) = #CurrentMonth )
BEGIN
SET #DayOfWeek = Datepart(weekday, Dateadd(day, #DayOffset, Getdate()))
IF ( #DayOfWeek != 1
AND #DayOfWeek != 7 )
BEGIN
SET #WorkDaysLeftInMonth = #WorkDaysLeftInMonth + 1
END
SET #DayOffset = #DayOffset + 1
END;

My query has 2 different tables in 2 different databases.

Answer 1

Currently, the stored procedure is using CTEs to create "temporary tables" based on (ugly and monstruous) queries and then use them to fill a table.
In general terms, a CTE is a table made from the results of a query, that's only usable by the immediate next query (this is: you create a CTE, then use it on a SELECT, INSERT, UPDATE... then the CTE gets destroyed).
What the SP is doing is this:
Creates CTE j using info and calculations from certain tables
Uses info from CTE j to create CTE i
Uses info from CTE i to create a temporary table #outputToCache
Dumps info from #outputToCache into a physical table cache.PurchasingSupplyChainNeeds
SELECTs and returns the info from cache.PurchasingSupplyChainNeeds as the resultset from the stored procedure
The error you're getting is because you're replacing the creation of CTE i with your own query, but i is still used later on to fill the temporary table.
Now, you say that what you are trying to achieve, is to retrieve a smaller amount of data from this last "cache" table for a separate page. IF I UNDERSTAND CORRECTLY (emphasized because I'm not 100% sure I got it already) you shouldn't modify this stored procedure (this is, add your query into it) because that would change the output of it, and would break anything that uses it. Not only that, your query is using info from the cache table, but the part you're trying to replace is what creates the CTE i that ultimately fills such table.
If what you really want to do is to change the resultset returned from this SP, then the query you need to replace with your own is the one that's assigned to the #sqlStmt variable at the end, so instead of
SET #sqlStmt = 'select * from [cache].[' + #myName + ']'
you would have
SET #sqlStmt = 'SELECT tb_1.SubPart AS [Sub Part], SUM(tb_1.FinalItemSubPartQuantity) [Sub Part Quantity Needed], SUM(tb_1.FinalItemSubPartQuantity * tb_2.SalesWeek1) [Total Sales Week 1],...'
*Note the change of quoted aliases to square-bracketed ones
If your query is meant to return information for a separate page, you should create another stored procedure with your query and then call this new SP from this separate page. This is of course if this cache table doesn't get emptied/deleted by a different process later on. If this is the case, then you're into a world of pain, as you would either need to duplicate this existing SP almost in its entirety into your new SP and change the output as stated above; add an optional parameter that determines wich output should this SP return (e.g. if the parameter is 1 the output is the same as now, but if the parameter is 2 the output is your query); or change this existing stored procedure to not return a value and make other(s) to calls this one and return information as needed. Probably the last option is the "least ugly" one.
