hi!
I wrote sql server stored procedure since 2002,as a matter of experience,the best way to reduce bugs and errors is keep good habit for coding.
for example,code with EditPlus text-editor rather than sql server query analyzer,and use the syntax file & auto-completion for *.sql file type.
of course,one important factor is has clear structure of application,and then,produce high-quality code.
there is some code of mine:
/*

-- Remove the existing Stored Procedure --
if (exists (select * from sysobjects where name = 'usp_m_getcPresentDetailData' and type = 'P'))
drop proc usp_m_getcPresentDetailData
go

Good style:
SELECT
@availableQty = (
SELECT COUNT(*) As AvailableQty
FROM vu_unsoldproducts
GROUP BY
serial,
prodlineid,
manid,
modelid
HAVING
prodlineid = @prodLineID
AND
manid = @manid
AND
modelid = @modelID
AND
UPPER(serial) = UPPER(@Serial)
)
Bad style:
Select @availableQty = (select count(*) AvailableQty FROM vu_unsoldproducts
Group by serial, prodlineid, manid, modelid
HAVING
prodlineid = @prodLineID
AND
manid = @manid
AND
modelid = @modelID
AND
UPPER(serial) = UPPER(@Serial))

hi
well I just need to build a stored proc to make a lot of insertions at one place for the user, the thing is that user can give the required quantity and the data would get inserting by matching the number of rows equal to taht of this quantity (it ould already be chked that the number is less or equal to existing Quantity or not). so the data gets inserted into this other table.
I think may be I'd need to have cursors here coz I need to access each row of the extracted data indivually. But I'm not too fond of using them though.
but even if I have to use them can u plz give me a sample code for that in TSQL
the tables are as follows
BranchBillDetail(purchID, billid) <--insertion in this
vu_unsoldproducts(purchID, modelid, prodlineid,manid, etc...) searching done on this
thanks in advance

--This should solve your problems if I understand your request.
--How to do it w/o a cursor
DECLARE @RowCount INT
DECLARE @DataTable TABLE(

SELECT @RowCount = Count(*) FROM [Data Source]
WHILE @RowCount > 0
BEGIN
INSERT YADAYADA
WHERE RowNum = @RowCount
SET @RowCount = @RowCount - 1
END

yea it has given me some idea to move on u know. I'm a bit out of touch with that project for a few days now and I'll certainly look into it again to get the job done..

Is it possible to write an INSERT statement to add a row to a table with just a single column which is an identity column ?
e.g
Create Table Amit (Id int Identity(1,1))
Then what would be my insert statement.
Note:
Please note i don't want to use set auto_identity amit On 
Plase reply....

INSERT INTO Amit DEFAULT VALUES

Some problems are so complex that you have to be highly intelligent and well informed just to be undecided about them.

i have table contain tow date getdate and expiredDate how can i get the deferent between thes dates
|
|
|
|
|
well if u r using Oracle 9i u can simply subtract the two dates to get the number of days b/w them.
and in SQL Server I think there are some functions like DateDiff()
go chk it out urself... u can use the books online given in the sql server menu. and search over these type of contents or use index or whatever u know what I mean!
Hope it helps...

Hi friends,

I am analyzing some access database queries and came across this...
UPDATE BCQOH <br />
LEFT JOIN BCQOH_w_Cost ON BCQOH.[2ndItemNumber] = BCQOH_w_Cost.[2ndItemNumber] <br />
SET BCQOH.Cost = [BCQOH_w_Cost]![Cost];
Is the exclamation mean not equal? If so is this just an easier way to write it than a WHERE table1.field NOT EQUAL to table2.field?
|
|
|
|
|
Unless BCQOH.Cost is a boolean field, I would think that its just another form of the '.' operator. In Access the notation used is [table]![field].
Just guessing...

I was playing with SQL the other day and ran across a way to automatically create XML Documents with just T-SQL and Built in funtionality of SQL Server 2005. It goes like this;
SELECT * FROM [Table]
FOR XML AUTO, ELEMENTS
Then you click on the results. A new window opens with your Schema / Data in place.
I thought it was cool, and I hope it helps someone.

Hi,
I have posted a couple of questions on the forum this week, and no one has been able to help me the way I need help.
I have a database on my local machine, I need to take that exact database and upload it to the hosting server, without loosing any data or PK and FK relations, and I need the Identity Specification to remain the way that I set it.
If I import it to the hosting server then all the Identity Specifications are set to No again. I get huge errors when trying to import the data from my local ASP Membership tables to the hosting servers tables. Because of all the PK and FK constraints.
Please can some one help. I am really frustrated.
I am using SQL Server 2005.
Regards
ma se

Use Backup & Restore. You will have to establish security since you are changing domain/workstation. See BOL.

Hello c'pians,
I have got two SQL databases on seperate machines (master/slave). I am able to connect to both the databases using Enterprise Manager. Both databases
have identical tables. What i would like to do is write a trigger which fires when a new row is inserted into the master db and inserts the same data into the slave database.
What i would like to know is, is it possible to write a trigger which can insert data into a completly seperate database?
|
|
|
|
|
It is possible and fairly straight forward. I am doing this from memory as I only have SQL Server 2005 in front of me (so forgive if directions are slightly off). Open Enterprise Manager, create a linked server on the master DB to the slave DB. Then you will be able to access the slave DB in your trigger basically as if you were acessig another (local) DB. I hope this helps.
|
|
|
|
|
Yes, use linked server. Steps would be
a) Create Linked server for your slave on master server by using enterprise mgr or sp_addlinkedserver.
b) Write Trigger on master table...and do somothing like as below
Insert into Slave.Table values(..............)
where slave is linked server name.....
Simple........

well no buddy's gonna tell u the whole story abt database programming out here... but I suggest u should visit www.msdn.com or use msdn at home and check out the articles on ADO or may be ADO .NET and stuff like that.
there are things like datasets, dataadapters, odbc, etc to watch out for
wish u best of luck...

The stored procedure gives me what I want, which is a ranking with points for each store in the company based on certain fields, but I also want to compare this week's vs. the same week last year transactions. I thought I could just do another select command, but it's not working. The same I did use, worked fine on it's own - but when I insert it into the already existing code, it dies... any suggestions would be greatly appreciated.
Signed - newbie 
=====SAMPLE STORED PROCEDURE====
SELECT TransID, StoreNo, StoreName, TotalPoints, TotalTransactions,
RANK() OVER (ORDER BY TotalPoints DESC) AS Ranking
FROM (
-- SubQuery Starts here
select WeeklyReports.TransID, WeeklyReports.StoreNo, Stores.StoreName,
-- Calculate TotalPoints first
rank() over (order by abs(WeeklyReports.ActualVsTheoFoodCost) desc)+
rank() over (order by abs(WeeklyReports.Cash) desc)+
rank() over (order by WeeklyReports.SalesVsBudgetPercent)+
rank() over (order by WeeklyReports.Overtime desc)+
rank() over (order by WeeklyReports.Deletes desc)+
rank() over (order by WeeklyReports.Puw112 desc)+
rank() over (order by WeeklyReports.Puw58 desc)+
rank() over (order by WeeklyReports.PuwDay desc)+

rank() over (order by ROUND((WeeklyReports.AllVoids/WeeklyReports.NetSales)*100,2) desc) as TotalPoints,
WeeklyReports.TotalTransactions,
This is where I run into problems. If I delete this section, the stored procedure works find, but I would really like it to work.
<br />
--SELECT DISTINCT WeeklyReports.TransID, WeeklyReports.StoreNo, WeeklyReports.WeekEndDate, WeeklyReports.TotalTransactions, <br />

--FROM WeeklyReports INNER JOIN<br />
-- WeeklyReports AS WeeklyReportsLY ON DATEADD(week, - 52, WeeklyReports.WeekEndDate) = WeeklyReportsLY.WeekEndDate<br />
--WHERE (WeeklyReports.TotalTransactions is not null and WeeklyReports.TotalTransactions <> 0 and<br />
-- WeeklyReportsLY.TotalTransactions is not null and WeeklyReportsLY.TotalTransactions <> 0)<br />
And this is the continued part of the good procedure.
abs(WeeklyReports.ActualVsTheoFoodCost) as FoodCostVariance,
rank() over (order by abs(WeeklyReports.ActualVsTheoFoodCost) desc) as ptsFoodCostVariance,
abs(WeeklyReports.Cash) as Cash,

rank() over (order by WeeklyReports.Puw112 desc) as ptsPuw112,
WeeklyReports.Puw58,
rank() over (order by WeeklyReports.Puw58 desc) as ptsPuw58,
