Stored Procedures And For Loops
Jun 2, 2004
Hi, I'm trying to call a stored procedure in a for loop within an ASPX page. My code runs fine but it seems to skip over the function which uses the stored procedure. The procedure basically copies files from the the client to the server. I have the upload portion working which physically copies the files from the client to server but when it comes to copying the path into a field in a table it totally skips it.
Some one suggested that the for loop is operating too fast for the stored procedure to work.
Any suggestions

Hi,
This Might be a really simple thing, however we have just installed SQL server 2005 on a new server, and are having difficulties with the set up of the Store Procedures. Every time we try to modify an existing stored procedure it attempts to save it as an SQL file, unlike in 2000 where it saved it as part of the database itself.
Thank you in advance for any help on this matter

Using SQL 2005, SP2. All of a sudden, whenever I create any stored procedures in the master database, they get created as system stored procedures. Doesn't matter what I name them, and what they do.
For example, even this simple little guy:
CREATE PROCEDURE BOB
AS
PRINT 'BOB'
GO
Gets created as a system stored procedure.
Any ideas what would cause that and/or how to fix it?
Thanks,
Jason

How do I search for and print all stored procedure names in a particular database? I can use the following query to search and print out all table names in a database. I just need to figure out how to modify the code below to search for stored procedure names. Can anyone help me out?
SELECT TABLE_SCHEMA + '.' + TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'

Seems like I'm stealing all the threads here, : But I need to learn :) I have a StoredProcedure that needs to return values that other StoredProcedures return.Rather than have my DataAccess layer access the DB multiple times, I would like to call One stored Procedure, and have that stored procedure call the others to get the information I need. I think this way would be more efficient than accessing the DB multiple times. One of my SP is:SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, S.Name AS 'StatusName', S.ItemDetailStatusID, S.InProgress as 'StatusInProgress', S.Color AS 'StatusColor',T.[Name] AS 'TypeName', T.Prefix, T.Name AS 'ItemDetailTypeName', T.ItemDetailTypeID FROM [Item].ItemDetails I INNER JOIN Item.ItemDetailStatus S ON I.ItemDetailStatusID = S.ItemDetailStatusID INNER JOIN [Item].ItemDetailTypes T ON I.ItemDetailTypeID = T.ItemDetailTypeID However, I already have StoredProcedures that return the exact same data from the ItemDetailStatus table and ItemDetailTypes table.Would it be better to do it above, and have more code to change when a new column/field is added, or more checks, or do something like:(This is not propper SQL) SELECT I.ItemDetailID, I.ItemDetailStatusID, I.ItemDetailTypeID, I.Archived, I.Expired, I.ExpireDate, I.Deleted, EXEC [Item].ItemDetailStatusInfo I.ItemDetailStatusID, EXEC [Item].ItemDetailTypeInfo I.ItemDetailTypeID FROM [Item].ItemDetails IOr something like that... Any thoughts?

Greetings:
I have MSSQL 2005. On earlier versions of MSSQL saving a stored procedure wasn't a confusing action. However, every time I try to save my completed stored procedure (parsed successfully ) I'm prompted to save it as a query on the hard drive.
How do I cause the 'Save' action to add the new stored procedure to my database's list of stored procedures?
Thanks!

Does anyone know if you can use do while or do until loops in stored procedures? If so what is the syntax?

2)if count=0, then I want to insert into another table 'group' after getting its key.
I am totally lost, can somebody point me in the right direction.
how do I get the individual name so that I can insert into the group table,
I tried 'select @name=name, that gave no results'.
Thanks
while (SELECT name FROM names WHERE name in (select name from Group) and status = 'M' )=0

We recently upgraded to SQL Server 2005. We had several stored procedures in the master database and, rather than completely rewriting a lot of code, we just recreated these stored procedures in the new master database.
For some reason, some of these stored procedures are getting stored as "System Stored Procedures" rather than just as "Stored Procedures". Queries to sys.Objects and sys.Procedures shows that these procs are being saved with the is_ms_shipped field set to 1, even though they obviously were not shipped with the product.
I can't update the sys.Objects or sys.Procedures views in 2005.
What effect will this flag (is_ms_shipped = 1) have on my stored procedures?
Can I move these out of "System Stored Procedures" and into "Stored Procedures"?
Thanks!

Hello
I'm start to work with SSIS.
We have a lot (many hundreds) of old (SQL Server2000) procedures on SQL 2005.
Most of the Stored Procedures ends with the following commands:
SET @SQLSTRING = 'SELECT * INTO ' + @OutputTableName + ' FROM #RESULTTABLE'
EXEC @RETVAL = sp_executeSQL @SQLSTRING
How can I use SSIS to move the complete #RESULTTABLE to Excel or to a Flat File? (e.g. as a *.csv -File)
I found a way but I think i'ts only a workaround:
1. Write the #Resulttable to DB (changed Prozedure)
2. create data flow task (ole DB Source - Data Conversion - Excel Destination)
Does anyone know a better way to transfer the #RESULTTABLE to Excel or Flat file?
Thanks for an early Answer

Hi, I have below psuedo code ... it will display correct result, however, it takes a bit longer time to display all results. I think it's because we have so many loops, and each record from the loop will do a query from database. I need some advice about how to speed up the process time. Thanks in advance.

I have a stored procedure that I am trying to write. I want it to Grab a list of ids from one table, then loop through that list and select a group of records from a second table based on the first list. The 2nd list can have 1 + records per item from the first list. With in that record, I need to check the values in 2 fields, if the values = something I update a third field and move on to the next. So I need to be able to loop thru the second set also. Currently I have a cursor with in a cursor, but was told that was slow and not a good idea, so I am trying to figure out what other options I have.
Thanks in Advance

Hello all.
I'm mostly a VB.Net developer. I've been working on a intranet app that allows poeple in our company to self regisiter for access to Tools/Systems.
The data stucture: 1 Request with many Users requesting access.. Also on the same request, many applications requested for those same people.
After the application routes some 'Manager Reviews' and Updated the tblRequest, approving the request, I combine the Information into a tblRegistrations.
So there is a Matrix created.
The Users requested are (User1, User2, UserX....)
The Apps requested are (App1, App2, Appx....)
I created a Stored Proc that reads the List of USers, and inserts a record into tblRegistered for each App that was requested.
User1, App1
User1, App2
User1, App3
User1, Appx
User2, App1
User2, App2
User2, App3
User2, AppX
UserX, AppX
...., ....
I user 2 cursors, Nested.
The outer Cursor is the List of Users, and the inner Cusros is the list apps.
I appreciate if somone can show me how to do this with some other looping structure, or if not, examine the Decalrative statement of the Cursor, and define the propteries to make it most efficient, ie Static Local Forward Only, ect.
As I said, I don't DB Developer Experience.
Below is the copy of the Working Stored Proc:

I brought my server to it's knees by creating 499.9GB of transaction log on a 500GB drive. Oops.
The db recovery model is SIMPLE.
I want to loop through some code, and minimize the transaction log file size. My second query here has an explicit transaction. Assume this code will loop about....1/2 Billion times. Is one (or both) of these going to record ALL 500,000,000 update statements in the Transaction Log (remember SIMPLE recovery)? Will the second one of these record a single transaction 500,000,000 time but not overwhelm the Log file due to simple recovery?
Any thoughts anyone?

I am writing a set of store procedures (around 30), most of them require the same basic logic to get an ID, I was thinking to add this logic into an stored procedure.
The question is: Would calling an stored procedure from within an stored procedure affect performance? I mean, would it need to create a separate db connection? am I better off copying and pasting the logic into all the store procedures (in terms of performance)?
Thanks in advance

I am trying to figure out an efficient way of comparing two tables of identical structure and primary keys only I want to do a join where one of the tables reveals values for records which have been modified and/or updated.
To illustrate, I have two tables in the generic form:
id-dt-val
For which the 'val' in table 2 could be different from the 'val' in table 1 - for a given id-dt coupling that are identical in both tables.
Does anyone know of an efficient way I could return all id-dt couplings in table 2 which have values that are different from those with the same id-dt couplings in table 1?
NOTE: I am asking this because I am trying to avoid explicit comparisons between the 'val' columns. The tables I am working with in actuality have roughly 900 or so columns, so I don't want this kind of a monster query to do (otherwise, I would simply do something like where a.id = b.id and a.dt = b.dt and a.val <> b.val) - but this won't do in this case.
As a sample query, I have the following script below. When I attempt the where not exists, as you might expect, I only get the one record in which the id-dt coupling is different from those in table 1, but I'm not sure how to return the other records where the id-dt coupling is the same in table 1 but for where modified values exist:
create table #tab1
(
id varchar(3),
dt datetime,
val float
)
go
create table #tab2
(
id varchar(3),
dt datetime,
val float
)
go
insert into #tab1
values
('ABC','01/31/1990',5.436)
go
insert into #tab1
values
('DEF','01/31/1990',4.427)
go
insert into #tab1
values
('GHI','01/31/1990',7.724)
go
insert into #tab2
values
('XYZ','01/31/1990',3.333)
go
insert into #tab2
values
('DEF','01/31/1990',11.111)
go
insert into #tab2
values
('GHI','01/31/1990',12.112)
go
select a.* from #tab2 a --Trouble is, this only returns the XYZ record
where not exists
(select b.* from #tab1 b where a.id = b.id and a.dt = b.dt)
go
drop table #tab1
drop table #tab2
go
I really dont' want to have to code up a loop to do the value by value comparison for inequality, so if anyone knows of an efficient set-based way of doing this, I would really appreciate it.
Any advice appreciated!

I need help creating the following report.
I need to modify the folliwng report to produce a weekly version of it.
To get a weekly version, simply find the first day of the week for the @dtm1 value :
should be something like @firstofweek=dateadd(day,(datepart(dw,@dtm1)*-1)+1,@dtm1) to get the Sunday date
I think i will then then need to loop through from firstofweek to last of week (last of week will be the Saturday)
would suggest having a dayofweek column on your temporary table.

DECLARE @mybit AS INTEGER
SET @mybit=10
SELECT @mybit = CASE datepart(dw,@dtm1)

hi,
My problem is basically i need to call a stored proc for each entry in a table, i.e, basically a for loop calling stored procs with parameter coming from the table. I know two ways of doing this .. using cursor and using while loop with temp table. I dont like both approaches. Is there any good practice for this situation..
declare mycur cursor fast_forward for select ID from sometable
open mycur
FETCH NEXT FROM mycur
INTO @AID
WHILE @@FETCH_STATUS = 0
begin
exec dbo.storedproc @AID
FETCH NEXT FROM mycur INTO @AID
end
CLOSE mycur
DEALLOCATE mycur

Hi all - I'm trying to optimized my stored procedures to be a bit easier to maintain, and am sure this is possible, not am very unclear on the syntax to doing this correctly. For example, I have a simple stored procedure that takes a string as a parameter, and returns its resolved index that corresponds to a record in my database. ie
exec dbo.DeriveStatusID 'Created'
returns an int value as 1
(performed by "SELECT statusID FROM statusList WHERE statusName= 'Created')
but I also have a second stored procedure that needs to make reference to this procedure first, in order to resolve an id - ie:
exec dbo.AddProduct_Insert 'widget1'
which currently performs:SET @statusID = (SELECT statusID FROM statusList WHERE statusName='Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
I want to simply the insert to perform (in one sproc):
SET @statusID = EXEC deriveStatusID ('Created')INSERT INTO Products (productname, statusID) VALUES (''widget1', @statusID)
This works fine if I call this stored procedure in code first, then pass it to the second stored procedure, but NOT if it is reference in the second stored procedure directly (I end up with an empty value for @statusID in this example).
My actual "Insert" stored procedures are far more complicated, but I am working towards lightening the business logic in my application ( it shouldn't have to pre-vet the data prior to executing a valid insert).
Hopefully this makes some sense - it doesn't seem right to me that this is impossible, and am fairly sure I'm just missing some simple syntax - can anyone assist?

I have a problem when using nested loops in my Control Flow. The package contains an outer Foreach Loop using the Foreach File Enumerator which in my test case will loop over two files found in a directory. Inside this loop is another Foreach Loop using the Foreach Nodelist Enumerator. Before entering the inner loop a variable, xpath, is set to a value that depends on the current file, i e /file[name = '@CurrentFileName']/content. The Nodelist Enumerator is set to use this variable as its OuterXPATHString. Now, this is what happens:
First Iteration:
The first file is found and the value of xpath = /file[name = 'test1.txt']/content. When the inner loop is entered it iterates over the content elements under the file with name test1.txt as expected.
Second Iteration:
The second file is found and the value of xpath = /file[name = 'test2.txt']/content. When the inner loop is entered it unexpectedly still iterates over the content elements under the file with name test1.txt.
My question is: Should it not be possible to change the loop condition of an inner loop in an outer loop such that the next time it is entered it will be done based on the new condition? It seems that the xpath variable is read once, the first time, and never again. If that is the case, does anyone know of a workaround?
Regards,
Lars Rönnbäck

It would appear that if a Child package is called more than once from a Parent using the 'Execute Package' task, then after the first execute the Parent Package Variables are not applied to child package. I.E we build dimensions in a master database and these are then loaded to a number of topic specific datamarts. We simply pass Parent variables to the child that hold source & target connection strings, the first time the package is called the correct database is accessed, subsequent Executes ignore the variables and use the original values. Manipulating the (our) event queue to run the package once results in the correct behaviour
Are packages cached when they are called from a Parent? if so is there a flag that I have missed to force a reload each time a child is executed?
This has just become a big problen for us so any guidance would greatly appreciated.

The problem:
I have 2 tables, with a one to many relationship - lets say customers, and order items.
Each order record has a field that is meant to be a comma delimited list (they are reference numbers) that is driven by the quantity field. So, say in the order record, an item has a quantity of 3. The reference number will look like this:
1, 2, 3
And if the next order item for that customer has a quantity of 4, the reference number value is
4, 5, 6, 7
And the final item with quantity of 2:
8, 9
Reference numbers can either be auto assigned (and are in my web application) or manually set. If manually set they will NOT be numeric.
In my web application, it is possible for users to return to a customer's order and edit a line item. My problem is when users changes the quantity of an item, and I have to reset the reference numbers.
If the quantity of line item 2 changes from 4 to 3, I need to reset all the values for that, and any other, order item that comes after it:
4, 5, 6 (2nd)
7,8 (3rd with same quantity of 2).
I felt a cursor would be the best way to handle this. But I am having trouble re-assigning my variable to be the next number in the series when the cursor is running.
This is what I have so far. The print lines and hard coded values are for debugging purposes only.
DECLARE @NumberingType varchar(10)
DECLARE @TotalSum int
DECLARE @DoorLineItemID int
DECLARE @Quantity int
DECLARE @SeedInt int
SET @SeedInt = 1
SELECT @TotalSum = SUM(Quantity) FROM DoorLineItems WHERE UniversalOrderID = 12345
DECLARE UpdateRefCursor CURSOR FOR
SELECT DoorLineItemID, Quantity FROM DoorLineItems WHERE UniversalOrderID = 12345 AND NumberingType = 1
OPEN UpdateRefCursor
FETCH NEXT FROM UpdateRefCursor INTO @DoorLineItemID, @Quantity
DECLARE @RefNumberLine varchar(1024)
SET @RefNumberLine = ''
WHILE @@FETCH_STATUS = 0
BEGIN
WHILE @SeedInt <= @Quantity
BEGIN
SET @RefNumberLine = @RefNumberLine + CONVERT(varchar, @SeedInt, 101) + ', '
SET @SeedInt = @SeedInt + 1
END
PRINT @RefNumberLine
SET @SeedInt = @Quantity + @SeedInt
PRINT 'new seed: ' + CONVERT(varchar, @SeedInt, 101) + 'Quantity ' + CONVERT(varchar, @Quantity + @SeedInt, 101)
FETCH NEXT FROM UpdateRefCursor INTO @DoorLineItemID, @Quantity
END
CLOSE UpdateRefCursor
DEALLOCATE UpdateRefCursor
This returns the same delimited string for X number of items. So I'm getting this:
1,2,3
1,2,3
1,2,3
When I really want the results described above.
What am I doing wrong?
Thanks!

I need a stored proc to kill spids, but the following sproc loops infinitely with the same [correct] spid being printed out. What am I doing wrong?
The select statement, when I execute it via the query grid, returns the correct and finite number of spids.
Any help greatly appreciated.
Judith
CREATE PROCEDURE rasp_KillDBProcess
@dbname varchar(128)
AS
declare @KillSpid smallint
declare @SQL varchar(1000)
--
declare DBCursor cursor Forward_only for SELECT distinct l.spid
FROM master.dbo.syslocks l INNER JOIN
master.dbo.sysdatabases d ON l.dbid = d.dbid
WHERE (d.name = N'coj_pcisdata')
open DBCursor
--
Fetch next from DBCursor into @Killspid
--
While (@@Fetch_status <> -1)
Begin
If (@@Fetch_status <> -2)
begin
print 'spid = ' + cast(@killspid as varchar(12))

end
Fetch next from DBCursor into @Killspid

close dbcursor
deallocate dbcursor
print 'end'
return
