BLOB's And Stored PRocedures
Sep 28, 2000
We are currently working on a method to store Visio drawings in a SQL Server database. One approach we looked at was to take and store the coordinates of each individual object in the drawing in a table, and then pull those coordinates back out when we need to render the drawing.
The second approach we are examining is the use of BLOB's; specifically, store the entire Visio drawing as a BLOB in SQL Server 7.
We have only been able to find examples utilizing ADO. Is anyone aware of any method to save BLOB's using stored procedures? We'd like to use this method fore simplicity and maintenance sake.
Any hepl would be appreciated.
Thank You.

Hi,
Can we insert a blob in the database(eg: doc, jpeg, pdf, etc) from the sqlcmd prompt. I want to insert few files into my table having varbinary(max) column and i dont want to use any front end tool for making such insertions. What i am thinking of is providing a file system path for a particular file(eg: doc, jpeg, pdf, etc) to a stored procedure so that it can be inserted into the database, something that we can do via Oracle's sqlldr tool.
Regards
Salil

I want to know the differences between SQL Server 2000 storedprocedures and oracle stored procedures? Do they have differentsyntax? The concept should be the same that the stored proceduresexecute in the database server with better performance?Please advise good references for Oracle stored procedures also.thanks!!

I would like to extract a file from a database. The file is stored in a BLOB format
Can I extract the BLOB file from the database using an SQL code/command or is there another way in which I can extract the file?
The file is stored as a BLOB but is actually a ZIP file (if that makes any difference)
What is the normal method of extracting a BLOB file?

Hi,
I want to load a file into a blob column using a stored proc. The file will be on a UNC path on the network. Is there a system stored proc or any utility that can be fired off from the sp, using xp_cmdshell that will take a file path from the filesystem and load it into a blob column in a database table.
I have worked with blob fields in the past but in those instances I loaded the blobs into the database from front end ADO.net code. This time around I need to pull this off stricktly from a stored proc.
Any help will be appreciated.
thank you.

All,
I work with Microsoft SQL Server 2005 on windows XP professional.
I'd like to create stored procdure to add image to my database (jpg file).
I managed to do it using VARCHAR variable in stored procedure
and then using EXEC, but it don't work directly.
My Table definiton:
CREATE TABLE [dbo].[Users](
[UserID] [int] IDENTITY(1,1) NOT NULL,
[Login] [char](10),
[Password] [char](20),
[Avatar] [image] NULL,
CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED
(
[UserID] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
My working solution using stored procedure:
ALTER PROCEDURE [dbo].[AddUser]
@Login AS VARCHAR(255),
@Password AS VARCHAR(255),
@AvatarFileLocation AS VARCHAR(255),
@UserId AS INT OUTPUT
AS
BEGIN
SET @Query = 'INSERT INTO USERS ' + CHAR(13)
+ 'SELECT '''+ @Login + ''' AS Login, ' + CHAR(13)
+ '''' + @Password + ''' AS Password,' + CHAR(13)
+ '(SELECT * FROM OPENROWSET(BULK ''' + @AvatarFileLocation + ''', SINGLE_BLOB) AS OBRAZEK)'
EXECUTE (@Query)
SET @UserID = @@IDENTITY
END
I'd like to use statement in the stored procdure:
ALTER PROCEDURE [dbo].[AddUser]
@Login AS VARCHAR(255),
@Password AS VARCHAR(255),
@AvatarFileLocation AS VARCHAR(255),
@UserId AS INT OUTPUT
AS
BEGIN
DECLARE
@Query AS VARCHAR(MAX)
SET @AvatarFileLocation = 'C:hitman1.jpg'
INSERT INTO USERS
SELECT @Login AS Login,
@Password AS Password,
(SELECT * FROM OPENROWSET(BULK @AvatarFileLocation, SINGLE_BLOB) AS OBRAZEK)
SET @UserID = @@IDENTITY
END
It generates error:
Incorrect syntax near '@AvatarFileLocation'.
My question is:
Why it does not work and how to write the stored procedure code to run this code without errors.
Thanks for any reply

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

We are debating what is industry “best practice� for serving huge numbers of images in an industrial scale website. More directly, which approach produces the best performance and the best scalability? For example, how do sites like ebay, Amazon, and other large sites handle the millions or billions of images they must deal with?
Store as BLOB in sql server?
Store in /images folder and store url text into sql server?
We always assumed that the second approach is what most sites must do. But do they?
One developer on our team maintains that storing one million or more image files in a directory will most certainly result in poor performance, because the server must scan the directory, searching for the correct file, each time a web request is made. The directory is not indexed (?) so performance must eventually suffer.
Other developer counters that storing millions of images as BLOBs into sql server will result in poor performance and HUGE database. An additional layer of access (webserver to sql server, back to webserver, then to client) causes a delay and performance hit.
Who is right? What do the gurus as the world class sites do?

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
John

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?

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...
(Iam just a beginner with SQL)

I am learning to make a ASP web site and feel that if i can do it the harder way using some stored procedures instead of using multiple datasources on each page requiring that it might be better. So i am wondering what are these used for:DECLARE vs just entering "@param1 varchar(30)"When i use "DECLARE @rc int" i get the error "Incorrect syntax near DECLARE"How to return values to ASP page in Visual Studio 2005 How to use @@rowcount - doesn't seem to work for me?i tried using DECLARE @rc intSET @rc = @@rowcountWhen to use GO, BEGIN etcIf i want to use the variable only in the procedure, and not needed to be inputed, do i need to put it in the CREATE PROCEDURE (section)?Should i use my own stored procedures or VS2005 created ones using datasources? not really procedures but SQL, in SQL can i do like IF ELSE? if i use my own i cant use the Optimistic Concurrency right? and whats that?

Hi,
Can anyone help me. I've created a stored procedure in sql server and I'm trying to run it from my asp.net page. On Database Explorer I can't see it, or any for that matter, however I can see tables in the same schema.
Also I can't see it when I build a table adapter either.
Can anybody help?

Hi,I have a procedure that insert some values into database. The point is, when somebody doesn't fill up a certain field on the form, I don't want the procedure to insert an empty row into database. The procedure looks like this:@tresc text, @id_test int, @odp text, @correct bit, @odp1 text, @correct1 bit, @odp2 text, @correct2 bit, @odp3 text, @correct3 bit, @odp4 text, @correct4 bit, @odp5 text, @correct5 bit, @odp6 text, @correct6 bit, @odp7 text, @correct7 bit ASDeclare @id_utworzonego_pytania intBeginSet nocount on Insert into Pytanie (tresc,id_test) values ( @tresc,@id_test) select @id_utworzonego_pytania=@@IDENTITY if(@odp is not null) BEGIN Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp,@correct,@id_utworzonego_pytania) END Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp1,@correct1,@id_utworzonego_pytania) Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp2,@correct2,@id_utworzonego_pytania) Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp3,@correct3,@id_utworzonego_pytania) Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp4,@correct4,@id_utworzonego_pytania) Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp5,@correct5,@id_utworzonego_pytania) Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp6,@correct6,@id_utworzonego_pytania) Insert into Odpowiedz (odp,correct,id_pytania) Values (@odp7,@correct7,@id_utworzonego_pytania) SET NOCOUNT OFF END And the code:con = new SqlConnection("Data Source=ELF;Initial Catalog=logos;Integrated Security=True"); SqlCommand cmd = new SqlCommand("StoredProcedure2", con); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new SqlParameter("@tresc", TextBox1.Text)); cmd.Parameters.Add(new SqlParameter("@id_test", id)); cmd.Parameters.Add(new SqlParameter("@odp", TextBox10.Text)); cmd.Parameters.Add(new SqlParameter("@correct", RadioButtonList2.SelectedValue)); cmd.Parameters.Add(new SqlParameter("@odp1", TextBox2.Text)); cmd.Parameters.Add(new SqlParameter("@correct1", RadioButtonList1.SelectedValue)); cmd.Parameters.Add(new SqlParameter("@odp2", TextBox3.Text)); cmd.Parameters.Add(new SqlParameter("@correct2", RadioButtonList3.SelectedValue)); cmd.Parameters.Add(new SqlParameter("@odp3", TextBox4.Text)); cmd.Parameters.Add(new SqlParameter("@correct3", RadioButtonList4.SelectedValue)); cmd.Parameters.Add(new SqlParameter("@odp4", TextBox5.Text)); cmd.Parameters.Add(new SqlParameter("@correct4", RadioButtonList5.SelectedValue)); cmd.Parameters.Add(new SqlParameter("@odp5", TextBox6.Text)); cmd.Parameters.Add(new SqlParameter("@correct5", RadioButtonList6.SelectedValue)); cmd.Parameters.Add(new SqlParameter("@odp6", TextBox7.Text)); cmd.Parameters.Add(new SqlParameter("@correct6", RadioButtonList7.SelectedValue)); cmd.Parameters.Add(new SqlParameter("@odp7", TextBox8.Text)); cmd.Parameters.Add(new SqlParameter("@correct7", RadioButtonList8.SelectedValue)); con.Open(); cmd.ExecuteNonQuery(); con.Close();It works perfectly if someone fill all the textboxes; but it is not required. So when you leave an empty textbox, the procedure inserts an empty row into database. Please, help!Regards,N.

Just a question or 2: Would it be faster in your opinion to attempt to insert a user into a database and should a database user already exist and an exception is caught for duplicate key existing... warn the user that it already exists in the database or rather by using a stored procedure to check. ( I'm trying to remove as much redundancy in code as possible)Now for another instance... I need to create either 3 procedures, 1st to check if a user exists with relevant data... the 2nd to update if there is already data, 3rd to insert should it be null. Or should i just use a single procedure that Checks if the user exists, if the @@rowcount = 1 then update else insert. ( all in 1 compact procedure) Id like to hear some peoples opinions in this matter as everyone seems to have different ways of doing things, I would just like to know whats best.
