Stored Procedures IF Statement

Sep 12, 2007

I have a webpage with a grid view in it that has sorting and filtering options.  I am trying to take the sql statement and turn them into stored procedures.  The problem I am having is converting this into a stored procedure.

SQL = "Select CustSite.CustSite, FileInfo.FileID, FileInfo.Date, FileInfo.OriginalFileName, ReportType.ReportType, Equip.Equip, Tech.Name From [CustSite], [FileInfo], [ReportType], [Equip], [Tech] Where(FileInfo.CustomerID = '" & Session("CustomerID") & "') AND (CustSite.CustSiteID IN (Select Customer_CustSite.CustSiteID From [Customer_CustSite] Where(CustomerID = '" & Session("CustomerID") & "'))) AND (ReportType.ReportTypeID = FileInfo.ReportTypeID) AND (Tech.TechID = FileInfo.TechID) AND (Equip.EquipID = FileInfo.EquipID) AND (Equip.CustSiteID = CustSite.CustSiteID)"

If Site.SelectedItem.Value <> "" Then

SQL += " AND (CustSite.CustSiteID = '" & Site.SelectedItem.Value & "')"

End If

If Date_Set.SelectedItem.Value = "Single" Then

SQL += " AND (FileInfo.Date = '" & Start_Date.SelectedItem.Value & "')"

ElseIf Date_Set.SelectedItem.Value = "Between" Then

SQL += " AND (FileInfo.Date Between '" & Start_Date.SelectedItem.Value & "' AND '" & End_Date.SelectedItem.Value & "')"

End If

If Report_Name.SelectedItem.Value <> "" Then

SQL += " AND (FileInfo.FileID = '" & Report_Name.SelectedItem.Value & "')"

End If

If Report_Type.SelectedItem.Value <> "" Then

SQL += " AND (FileInfo.ReportTypeID = '" & Report_Type.SelectedItem.Value & "')"

End If

If Equipment.SelectedItem.Value <> "" Then

SQL += " AND (FileInfo.EquipID = '" & Equipment.SelectedItem.Value & "')"

End If

If Tech.SelectedItem.Value <> "" Then

SQL += " AND (FileInfo.TechID = '" & Tech.SelectedItem.Value & "')"

End If

 

 Can someone point me in the right direction?  Thanks in advance for the help.

If Statement In Stored Procedures Help

Jun 23, 2008

Hi all. This has kept me up all night! I'm trying to populate a datgrid with multiple tables with relating keys in each table.

For ease, I've made the databases hopefully understandable.

DoctorsDB - (ID, Name, Phone)
FriendsDB - (ID, Name, Phone)
PetsDB - (ID, Name)
PeopleISawTodayDB - (MyID, MyName, DocID, FriendID, PetsID)

Now I need to generate a datagrid with the following details:
MyID, MyName, Doc's Name, Friend's Name, Pet's Name.

I have some success with the following code:

PROCEDURE dbo.PeopleISawTodayDB
@ID as Int
AS
BEGIN
SELECT
PeopleISawTodayDB.MyID, PeopleISawTodayDB.MyName, PeopleISawTodayDB.DocID, PeopleISawTodayDB.FriendID, PeopleISawTodayDB.PetID, DoctorsDB.ID, DoctorsDB.Name, FriendDB.ID, FriendDB.Name, PetDB.ID, PetDB.Name
FROM
PeopleISawTodayDB INNER JOIN
DoctorDB ON PeopleISawTodayDB.DocID = DoctorDB.ID INNER JOIN
FriendDB ON PeopleISawTodayDB.FriendID = FriendDB.ID INNER JOIN
PetDB ON PeopleISawTodayDB.PetID = Pet.ID
WHERE PeopleISawTodayDB.JobID=@ID
END



BUT it will only make a row appear if there are ID's in each of the PeopleISawTodayDB respective ID fields.

If I want to leave one blank (as in I didn't see that person that day), I would like it to still find the other details and populate the datagrid.

Can anyone lend a coding hand???? Cheers

Stored Procedures IF Statement (SQL2005)

Jan 30, 2006

Hello, I need to use a if statement in stored procedures.

What I need to know is the proper syntax because anything I try does not work.

I need to check if 24 hours passed:
datediff(hh, Users.LastLogin, GetDate())

Should return the number of hours that has passed. I need to use this in the IF statement, and I need to check if it's > 24.

Thanks =)!

USE Statement In Stored Procedures Two Databases, How Please?

May 23, 2008

This works great in a query:


USE KCADOWNLOAD

USE OUTHOUSE

GO

DELETE FROM OUTHOUSE.KCA_BLDGS_ACCES

INSERT INTO OUTHOUSE.OUTHOUSE.KCA_BLDGS_ACCES

(MAJOR, MINOR, ACCYTYPE, ACCYDESCR,

QUANTITY, SIZE, UNIT, GRADE, EFFYR, PCNTNETCONDITION, ACCYVALUE, DATEVALUED, UPDATEDBY,

UPDATEDATE,PID)

SELECT MAJOR, MINOR, ACCYTYPE, ACCYDESCR,

QUANTITY, SIZE, UNIT, GRADE, EFFYR, PCNTNETCONDITION, ACCYVALUE, DATEVALUED, UPDATEDBY,

UPDATEDATE,PID

FROM KCADOWNLOAD.dbo.KCA_BLDGS_ACCES AS KCA_BLDGS_ACCES_1



But the stored procedure only creates ONE Use statement:


USE [KCADOWNLOAD]

...etc.


I assume I can run an SP utilizing two databases...


The SP fails because it hasn't got a clue what OUTHOUSE is...


Thank you!!!

... Executing Stored Procedures In An INSERT Statement ...

Aug 28, 2002

I am trying to simulate the <sequence name>.nextval of oracle in SQL Server 2000.

The situation is that i need to be able to run programmatically INSERT statements. In Oracle I am able to do INSERT INTO TABLE_A (ID, NAME) VALUES (TABLE_A_SEQUENCE.NEXTVAL, 'MIKKO') in a single prepared statement in my code.

I know that to recreate this in SQL Server 2000 I need to create a stored procedure and table to set up a way to generate "the next value" to use in my INSERT. but the schema below forces me to do my insert in 2 steps (first, to get the next value. second, to use that value in the INSERT statement), since I cannot execute the stored procedure inside my INSERT statement.

Is there any way for me to generate values within my INSERT statement that would simulate Oracle's <sequence name>.nextval and allow me to execute my INSERT in 1 line of code?

TABLE
-----
CREATE TABLE sequences (
-- sequence is a reserved word
seq varchar(100) primary key,
sequence_id int
);

MS SQL SERVER STORED PROCEDURE:
-------------------------------
CREATE PROCEDURE nextval
@sequence varchar(100)AS
BEGIN
-- return an error if sequence does not exist
-- so we will know if someone truncates the table
DECLARE @sequence_id int
set @sequence_id = -1

UPDATE sequences
SET @sequence_id = sequence_id = sequence_id + 1
WHERE seq = @sequence

RETURN @sequence_id
END

Stored Procedures - Using Return Value From Dynamically Created SQL Statement

Jul 29, 2007

Hello,

This is my foray into Stored procedures, so I'm hoping this is a fairly basic question.

I'm writing a stored procedure, in which I dynamically create an SQL statement.
At the end of this, the SQL statement reads like:



Code SnippetSELECT COUNT(*) FROM StockLedger WHERE StockCode = 'STOCK1' AND IsOpen = 1 AND SizeCode = 'L' AND ColourCode = 'RED' AND LocationCode IS NULL AND RemainingQty > 0



Now this statement works a charm, and returns a single value. I want to assign this count to a variable, and use it further on in the stored procedure. This is where the problems start - I cant seem to do it.

If I hard code a statement, like



Code SnippetSELECT @LineCount = COUNT(*) FROM StockLedger
that works fine (although it brings back a count of all the lines).

But if I modify the dynamically created SQL Statement from earlier on to:



Code SnippetSELECT @LineCount = COUNT(*) FROM StockLedger WHERE StockCode = 'STOCK1' AND IsOpen = 1 AND SizeCode = 'L' AND ColourCode = 'RED' AND LocationCode IS NULL AND RemainingQty > 0
it doesnt work - it complains: Must declare the scalar variable "@LineCount".

Just to clarify, when I say "dynamically created an SQL statement, I mean that by a bunch of conditional statements I populate a varchar variable with the statement, and then eventually run it exec(@SQLStatementString)

So, my question would be, how do I do this? How do I make a dynamically generated SQL statement return a value to a variable?

Stored Procedures 2005 Vs Stored Procedures 2000

Sep 30, 2006

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

All My Stored Procedures Are Getting Created As System Procedures!

Nov 6, 2007



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

Using A Stored Procedure To Query Other Stored Procedures And Then Return The Results

Jun 13, 2007

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?

How To Save Stored Procedure To NON System Stored Procedures - Or My Database

May 13, 2008

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!

Stored Procedure Being Saved In System Stored Procedures

Apr 7, 2006

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!

SSIS And Stored Procedures Results Stored In #Tables

Mar 26, 2008

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

Calling Stored Procedures From Another Stored Procedure

May 8, 2008

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

John

Calling A Stored Procedure Inside Another Stored Procedure (or Nested Stored Procedures)

Nov 1, 2007

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?

Help With Stored Procedures

Feb 24, 2007

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.
