Looping In Stored Procedures
Apr 20, 2004
Hi
On my site I have a search engine which is used by potential customers to find out what courses we have on offer. Everytime something is written into the search engine the search criteria are logged in a table.
All the courses are held in a different table and I have enabled full text search on this table. Only two cloumns are searched for matches this is the course title and keywords.
What I want to be able to do is write a stored procedure which tells me which search criteria did not match any course titles or keywords. So that I can then assess what word people are using to search for courses and then add any which didn't match any courses to the keywords if they are relevant.
What I have done so far is create a view which contains a distinct list of search criteria. All i need to do now is create a stored procedure which loops through the courses table searching for each distinct search criteria.
I know this is possible to do using asp.net but I would like to do this on the database side to speed the process up a bit.
Any help on this matter would be much appreciated as I seem o be goinbg round and round in circles!!!
Thanking you in advance.
Steve

I have a stored procedure which adds a color + colortype to a table. I then need to select from a separate table all tools that support the colortype. Finally I need to insert into a separate table the tools + colortype. I would like to do this all in one stored procedure.My rough code is:INSERT INTO ColorsTable (color, colortype) VALUES (@color, @colortype);SELECT tools FROM ToolsTable WHERE colortype = @colortype[For Each tool] INSERT INTO MyTable tool, @colortypeMy problem is that I don't understand how to do a For Each Thank-you for any advice.

Hi, I need to code a stored procedure. It will select all the rows from a table. I then need some sort of looping mechanism to filter through all the rows. It is too difficult to handle the filtering with a simple 'WHERE' clause. I will have to do some data manipulation on fields within the rows to determine which ones I could use. I need for the SP to return all the rows which qualify. Could someone provide me with a link and/or some skeleton code to give me somewhere to start on how to code the SP?
Thank you.

Hello,
I am trying to creating a while loop.
I have created a variable called @MyCount
which I initially set to 1.
For each iteration of the loop, I would
like the value of @MyCount to increase by 1.
What am I doing wrong?
WHILE ( @MyCount <= @DaysInMonth )
BEGIN
/* put some code in here *./
@MyCount = @MyCount + 1
END
Thanks

I have an XML object (sent as a string, received as an XML datatype) that's in a Stored Procedure. Each row in the XML file will have 1 value from it inserted into one of three tables. The tables are depended upon the other value from the XML file.The XML File is layed out as:<Values> <value> <value>1</value> <key>My_Field</key> </value> <value>
<value>3523.2</value>
<key>My_other_Field</key>
</value></Values>I basically need to go through it row by row, find out what table I need to insert the value into using the key field.Any help with this would rock. I'm using SQL 2005.

I am writing a bit of code for our intranet using ASP.NET C# and SQL2005. We have a program called Aboutface that is a web based firm directory. We are using the SQL database it has in order to pull data out of it and integrate it into our intranet as we dont really care for its original interface.
I am most interested in setting up relationships.
An attorney only has one secretary that supports them, but a secretary can have many attorneys they support. This is the nature of my problem. The code below is my stored procedure. I am passing in an int which is the ID, and my goal is to generate the ID of and the name of the person who supports/is supported by. With 1 to 1 relationships, it works fine.. With more than that, it blows up because its finding multuple names (of attorneys being supported by a secretary)
I was told I might want to use a FOR EACH loop in the SP. I assume I would want to also generate a COUNT variable (to be used in the procedure and to also build the rows of my table outside of it.) and a NAME variable for each name it finds to populate the table.... but from there I am not sure if I am on the right lines of thinking or where to begin.
Any thoughts/suggestions would be greatly appreciated.
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[GetAttySectyData] (@id as int)
AS
BEGIN
DECLARE @First as varchar(200)
DECLARE @Middle as varchar(50)
DECLARE @Last as varchar(200)
SELECT @First = [value] FROM dbo.[text] WHERE efield_id = 10741 AND employee_id = (SELECT DISTINCT s.code as code from tblSectyData s, text t where t.employee_id = s.SectyCode and t.employee_id = @id )
SELECT @Middle = [value] FROM dbo.[text] WHERE efield_id = 10906 AND employee_id = (SELECT DISTINCT s.code as code from tblSectyData s, text t where t.employee_id = s.SectyCode and t.employee_id = @id ) SELECT @Last = [value] FROM dbo.[text] WHERE efield_id =10740 AND employee_id = (SELECT DISTINCT s.code as code from tblSectyData s, text t where t.employee_id = s.SectyCode and t.employee_id = @id )
Select ISNULL(@First, '') + ' ' + ISNULL(@Middle, '') + ' ' + ISNULL(@Last,'') AS FullName

Hello,I have a stored procedure that processes an individual file from adirectory and archives it in a subdirectory.Now, the problem is, when iexecute it , it will only process one file. What i want to do is to checkto see if there are any files in the folder, and if there are , processthem all, and once done, go to the next part in a DTS package, if there areno files, simply go to the next part in the DTS package. I tried an activexscript that would get the filecount in the folder, and if there were morethan 0 files in the folder, then DTS-sUCCESS and on "success" workflow , itwould run the stored procedure, and thus it woould process one file, then"on completion" the workflow connected it back to the activeX script(thuslooping), which would count the files again. Now if there were 0 files, itwould report DTS_FAILIURE, and I had it set up ,"on failiure" to go to thenext step in the package, but it wouldn't run.Someone mind showing me a ray of light?

I have a stored procedure that I want to basically pull in a code/codes which correspond to people. I then convert the code to the persons actual name that I then want to send back and add to a listbox.
Right now with the code I have, it returns just one name. I know I am doing something wrong, but I am not sure if what I want is possible with a stored procedure or if I am on the right track.
my code is as follows.
The proceedure I am running is as follows...
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[GetAttySectyData] (@id as int)
AS
BEGIN
DECLARE @First as varchar(200)
DECLARE @Middle as varchar(50)
DECLARE @Last as varchar(200)
DECLARE @Code as varchar(200)
Select @Code = [SectyCode] From tblMain2 as M LEFT JOIN tblSectyData as S ON M.Code = S.Code WHERE M.Code = @id
SELECT @First = [value] FROM dbo.[text] WHERE efield_id = 10741 AND employee_id = @Code
SELECT @Middle = [value] FROM dbo.[text] WHERE efield_id = 10906 AND employee_id = @Code
SELECT @Last = [value] FROM dbo.[text] WHERE efield_id =10740 AND employee_id = @Code
Select ISNULL(@First, '') + ' ' + ISNULL(@Middle, '') + ' ' + ISNULL(@Last,'') AS FullName
END
////which is called from SqlCommand ShowTeam = new SqlCommand("Exec dbo.GetAttySectyData '" + selectedEmployee + "' ", IntranetConnection);
To populate the listbox, I was running this. As I mentioned, I get one name.
IntranetConnection.Close();
IntranetConnection.Open();
IntranetReader = ShowTeam.ExecuteReader();
while (IntranetReader.Read())
{
TeamList2.Items.Add(IntranetReader["FullName"].ToString());
}
IntranetConnection.Close();

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

Hi,
I have a package that I need to loop (possibly multiple times) based on a return value from a stored procedure.
I know that in DTS you could use the return value of "execution status" to do this.
Is there a way in SSIS to loop based on a return value?
Thanks much

I am doing some administrative tasks and need to collect some principals information from multiple instances and user databases.
I have table "dbo.instances" with list of instances.
I have databases from "sys.databases".
How can I execute the query to get principals information from "sys.database_principals" on each remote instance and database. I know that can use cursor, but not sure how to do this with multiple servers and databases.

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

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!

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

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

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 used to do this with classic asp but I'm not sure how to do it with .net.Basically I would take a table of Categories, Then I would loop through those. Within each loop I would call another stored procedure to get each item in that Category. I'll try to explain, Lets say category 2 has a player Reggie Bush and a player Drew Brees, and category 5 has Michael Vick, but the other categories have no items.Just for an example.. Category Table: ID Category1 Saints2 Falcons3 Bucaneers4 Chargers5 FalconsPlayer Table:ID CategoryID Player News Player Last Updated1 1 Reggie Bush Poetry in motion 9/21/20062 1 Drew Brees What shoulder injury? 9/18/20063 5 Michael Vick Break a leg, seriously. 9/20/2006 Basically I would need to display on a page:SaintsReggie BushPoetry in MotionFalconsMichael VickBreak a leg, seriously.So that the Drew Brees update doesnt display, only the Reggie Bush one, which is the latest.I have my stored procedures put together to do this. I just don't know how to loop through and display it on a page. Right now I have two datareaders in the code behind but ideally something like this, I would think the code would go on the page itself, around the html.

Hello I have two stored procedures
@ID INT
AS
SELECT (CASE WHEN NUM >= 10 THEN CAST(PAID AS FLOAT) / CAST(NUM AS FLOAT) * 100 WHEN NUM < 10 THEN 0 END) AS PER
FROM (SELECT (SELECT COUNT(*) AS Expr1
FROM Event_data AS D LEFT OUTER JOIN
Events AS E ON E.id = D.Event_id
WHERE (D.Transaction_type = 1) AND (D.Player_id = @ID)) AS NUM,
(SELECT COUNT(*) AS Expr1
FROM Event_data AS D LEFT OUTER JOIN
Events AS E ON E.id = D.Event_id
WHERE (D.Transaction_type = 1) AND (D.Transaction_value > 0) AND (D.Player_id = @ID)) AS PAID) AS X
and
@ID INT
AS
SELECT P.*,'/' + DBO.GETCHIPFOLDER(@ID) + '/' + ISNULL(P.PHOTO,'BLANK.GIF') AS PIC,ISNULL(
(SELECT SUM(TRANSACTION_VALUE)
FROM EVENT_DATA WHERE PLAYER_ID=@ID AND TRANSACTION_TYPE=1
GROUP BY PLAYER_ID),0) AS WINNINGS FROM PLAYERS P
undefined P
The first returns a percentage for player wins, the second gives me a photo and sums the player winnings
I would like to combine the results so I can get the percentage and wininngs in one query, in another matter all together I would like create a procedure like the first but instead of returning only one player, I would like to return the percentage for each player
Thanks in advance for any light you can shine on this.

I have a question about stored procedures, Is it better to use stored procedures even if I only use it once at my site? Or is it better to write the sql-part directly in the sqldatasource?
And am I forced to create two different stored procedures even if they are exactly the same except the "Where-part"?
Now I have around 40 stored procedures, and quite many of them looks the same except the where-part...
