No, you have missed the point a bit.

SELECT Sum(CASE WHEN Sku_Statistics_File.ExcessSA=0 
AND Sku_Statistics_File.ExcessSOH=0
AND Sku_Statistics_File.StockOutFirst6wks=0 
AND Sku_Statistics_File.StockOutNext6wks=0 
AND Sku_Statistics_File.PastDue=0) THEN 1 ELSE 0 END) AS BALANCED
FROM SELECTEDPRODUCTS1
INNER JOIN Sku_Statistics_File ON (SELECTEDPRODUCTS1.LOCATION=Sku_Statistics_File.Location) AND (SELECTEDPRODUCTS1.PRODUCT=Sku_Statistics_File.Product);

the THEN is the first condition of your IIF (true), the ELSE is the second condition (false)

Sql Script to Pull Records Based on Specific Date within A Year

Hello All,
I have a sql script that pulls certain records by my company's fiscal year which ends 8/31/yyyy. As I am trying to pull records based on the year (yyyy) I have written a condition as such a.THRU_DATE = '8/31/' + Year(GetDate()), however I receive the following syntax error Syntax error converting the varchar value '8/31/' to a column of data type int. Of the course the Thru_Date column type is datetime. Can someone please assist with the proper syntax for such a condition. Thanks in advance to all that reply

I found the answer to my own question using the CAST function. FYI, a.THRU_DATE = CAST('8/31/' + @year AS DateTime).

I have to use aggregate function sum() on a table having more than 4 millions of records. It is a history table. Are there any tips to be followed. the queries are a follows

SELECT @TransferIn = isnull(sum(abs(trxqty)),0) 
FROM iv30300 WHERE doctype = 3 and itemnmbr = @itemnmbr 
and trnstloc = @route and docdate between @FromDate and @ToDate
				
SELECT @TransferOut = isnull(sum(abs(trxqty)),0) 
FROM iv30300 WHERE doctype = 3 and itemnmbr = @itemnmbr 
and trxloctn = @route and docdate between @FromDate and @ToDate 
				
SELECT @Sales = isnull(sum(abs(trxqty)),0) 
FROM iv30300 WHERE doctype=6 and itemnmbr = @itemnmbr and 
trxloctn = @route

In the above query @route,@FromDate and @ToDate are user inputs

Then you cant really optimize the table, can you?

Since you don't have any indexes, you cannot create them and you don't have joins, there's not much you can do. The only thing that comes in mind is that yu copy the data to another table (perhapes in another database), index it and execute the query there. However this isn't a good solution if you need the data to be up-to-date.

The need to optimize rises from a bad design.My articles[^]

Simply make a database backup and restore. Cool | :cool:

you can do one way of these:
1-Backup from source database and Restore on destination, for this option your database server must be same
2-using Import/export tool from Integration service of Sqlserver, for this option database server doesn't matter usually.

Detach the Database files (.mdf and .ldf).
Move the files physically.
Attach the files to the database.
If previous log is required attach both .mdf and .ldf or else only .mdf can be attached.

Karthik,

Detaching means, removing database files from the server and files will remain in the same place without connecting to server.

Good Morning Guys

I have the Following statement, that works well when i test it alone

declare @Results int exec [dbo].[sp_RestoreDatabase_O_Booking] 'MasekoTS','MasterDatabase', @Results OUT

But now, i want to include this code in a Stored Procedure and i tried to do it like this

SELECT @sql1 = 'Declare @Results int exec [dbo].[sp_RestoreDatabase_O_Booking] ''' + @DB + ''', ''' + @Filename + '''@Results OUT'''
execute ( @sql1 )

and i get the Following Error

Msg 105, Level 15, State 1, Line 1
Unclosed quotation mark after the character string 'sp_RestoreDatabase_O_Bookin'.
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'sp_RestoreDatabase_O_Bookin'.

Thank you

Instead of doing execute ( @sql1 ) try Print @sql1 to see where its missing a quote - thats my usual method.

Just a pointer to help you out in the future with debugging dynamic SQL. When you have a problem like this, rem out the EXEC(@SQL) and put a select @SQL or PRINT @SQL.

Take the returned value and attempt to exec it in a diff. query window. Compare your orig statement to the dynamic one and find the error.

I think the error in this case is the missing , after the file name.

Any suggestions, ideas, or 'constructive criticism' are always welcome.

Delete instead of Update

Is it sometimes better to just delete and then reinsert some records instead of updating them? I have a complex scenario which is hard to explain but I am thinking that instead of updating, deleting and inserting is a better option. Has anyone come across such a scenario where deletion and reinsertion is better than update?

Re: Delete instead of Update

If you are doing a delete of a set of records, as apposed to a delete of ALL records, then the table is scanned to locate the records to be deleted. The delete action also affects any indexes on the table. Insert also affects the indexes but is less costly.

Update only affects the indexes if the indexed fields are updated.

You can do both in management Studio with the execution plan and costs turned on and compare your specific process.
