Hi,
I have seen many examples at MSDN library related to SQL Querries in all queries one thing is same the way they use tables in there queries. BUT wht is this really i am not getting this, can anyone tell me.. the code and the problem is as follows:
Code Snippet
FROM Purchasing.ProductVendor JOIN Purchasing.Vendor
ON (ProductVendor.VendorID = Vendor.VendorID)In the above code u see "Purchasing.ProductVendor", I want to ask that wht is this
Purchasing Stands for, If we suppose that purxchasing is the database name then also
normally we use database name as Purchasing.dbo.ProductVendor BUT I am not getting that
what is this,
Please if someone knows then explain it to me,
Thanks.
As a burgeoning SQL developer I have never really understood the need for SQL Server / Enterprise Manager to show us the whole dbo.Table name thing. What is dbo, and why do we need to know deal with it?With that said, in my SQL 2005 Express database all of my project tables for my project management demo were named guard.pgUsers for example and not dbo.pgUsers.How come? Why did they get named different on their own?
SELECT row_number() over (order by MAX(HeadlineDate)) as Number, COUNT(ArticleID) AS [Count], MIN(DATEADD(dd, - (DAY(HeadlineDate) - 1), HeadlineDate)) AS HeadlineDate FROM dbo.ZMArticle WHERE PortalID=0
GROUP BY MONTH(HeadlineDate), Year(HeadlineDate) ORDER BY MAX(HeadlineDate) desC
SELECT row_number() over (order by MAX(HeadlineDate)) as Number, COUNT(ArticleID) AS [Count], MIN(DATEADD(dd, - (DAY(HeadlineDate) - 1), HeadlineDate)) AS HeadlineDate FROM dbo.ZMArticle WHERE PortalID=0 AND Expiredate <> Null GROUP BY MONTH(HeadlineDate), Year(HeadlineDate) ORDER BY MAX(HeadlineDate) desC
it doesn't return anything....
How can I change that

Hi,I have a corporate database with about 60 different tables that spansmanufacturing, accounting, marketing, etc.It is possible, but unwieldy, to establish a relationship for eachtable in the entire database through critical fields like customer_idor product_id.But should I do that?My question is: Is there such a thing as too many relationships? CanI establish referential integrity via relationships with criticaltables like Accounting, but leave the rest unconnected and simply useJOINS in my business code?Thanks,HC
I have been trying to straighten out the select statement(underlined) in the procedure below but no luck. It is at the link below:(User-Specific Paging from ASP.NET)http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag/html/scalenethowto05.aspI think the "author" messed up during the copy and paste.

I have installed the MSDN SQL 7.0 final release on 2 Win NT (1 server and 1 Wkst)
When I launch DTS, I CAN export/import ACCESS <--> SQL and vice versa
I CANNOT export/import SQL7 <--> SQL7
I have this error messsage : "The licence for installation of Microsoft SQL Server on your source and destination connections does not permit the use of DTS to transform data. refer to your licence agreement for more information"
any ideas why ? Is there any limitation with MSDN CD ?
I recently got me a new laptop with Vista preinstalled. All good and well, but when I try to install a program vital for my profession, I get an error (OS not supported for this program). In the install I can configure what components to install, one of them is MSDN 2000. My question is, will SQL Server Express take over what MSDN can't on Vista (and thus running the program needing the MSDN 2000), or will windows XP be the new OS on my brand new laptop in the future. Love Vista, hate the compatibility.
Where is the list for forums, When i started to write for Sqlserver, i never searched or looked for forum. Same did when i was working with the c#. Now I have to find the correct forum. So where is the list of those forums, thanks.
Hey all,I have a datagrid with populated by this query: SELECT TABLE_NAME, TABLE_TYPE FROM INFORMATION_SCHEMA.TABLES WHERE (TABLE_TYPE = 'BASE TABLE')I have paging, sorting and selection enabled.Now I am looking for a way to use a wild card as a placeholder for the table name in my select statements so I can use the valued selected from the datagrid.Example : SELECT * FROM %TABLENAME%TIAWOOHOO! my first post.
i got this stored procedure. i tried to modify it and now its giving me this scaler error.

I'm have a stored procedure that iterates through a list of numbers and adds an item for each number (user id) some of these ids are duplicates which is fine even necessary for the first part of my query but for the last I need to ensure that no duplicates id's are passed to the stored procedure, in this case called 'spInsertForBackupNote'. My thoughts here was to do something like this:
SET @Note_Buffer = @UserID -- @Note_Buffer being some kind of array?
IF @Note_Buffer = @UserID -- If its been added to the buffer we dont execute sp BEGIN Do Nothing here END
ELSE
BEGIN EXECUTE spInsertForBackupNote @FK_UserID, @FK_NoteID END
I know this would never work because it would always be false since I just added the same userid to the buffer that I want to add. But I think you see my problem. I know it should be an easy one but my TSQL is limited. I've posted the whole sp. Hope someone can help.
Hello all, I'm working on an ASP.NET with a SQL server for database. Some of the tables, for example, contain information such as different types of Fabrics (silk, cotton, etc..) . I'd like to have this table localizable (English and French for instance). Is this possible ? Is there an equivalent of resource files in SQL server ? Or do I have to do this manually ? (have 2 separate fields in the table for those 2 locales)
I have a DTS Package that I am running from a command line via .bat file. Does anyone know if there is a command to have the command window minimized or running in the background? I used the /Rep N command but that still leaves the window open until the package has executed.
Are there any examples of using DTS and XML/XLS? specifically, importing data. I have searched through BOL and cant find any, nor is there any reference to XML in the book "Professional SQL 2000 DTS"
I see a lot of example, but where do these example procedures go. Likedeclare (whatever)?below is an example i read. Where do you put this to make it execute, is itthe view screen or the stored procedure screen?I'm using MSDE now to learn, and I can't get nothing working except simpleselect query statements.In the northwind example (northwindcs), how would I do a parameter querylike this:Have a dialog box ask user to enter customerid to bring up. (in a query nownot a form)Also, how would you check if a certain customerid exist? Example, CHOPS isone customerid. If I wanted to use a query to check if it exist, and returnno records, but just do an action (like add a record) if it didn't exist,how?[color=blue]> CPU SQL> (ms)> -- Convert to varchar (implicitly) and compare right two digits> -- (original version -- no I didn't write it)> 4546 select sum(case right(srp,2)> when '99' then 1 when '49' then 1 else 0 end)> from sf>> -- Use LIKE for a single comparison instead of two, much faster> -- Note that the big speedup indicates that> -- CASE expr WHEN y then a WHEN z then b .> -- recalculates expr for each WHEN clause> 2023 select sum(case when srp like '%[49]9' then 1 else 0 end)> from sf[/color]I tried some variations of this, and indeed it seems that there is a costwhen the expression appears with several WITH clauses. I tried a variationof this, where I supplemented the test table with a char(2) column, so Icould factor out that the WITH clauses themselves were not the culprits.CREATE TABLE realthing (realta real NOT NULL,lasttwo char(2) NOT NULL)goINSERT realthing (realta, lasttwo)SELECT r, right(r, 2)FROM (SELECT r = convert(real, checksum(newid()))FROM Northwind..Orders aCROSS JOIN Northwind..Orders b) AS fgoDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE right(realta, 2)WHEN '99' THEN 1WHEN '49' THEN 1WHEN '39' THEN 1ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 20766 ms.goDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE WHEN right(realta, 2) LIKE '[349]9' THEN 1 ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 8406 ms.goDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE lasttwoWHEN '99' THEN 1WHEN '49' THEN 1WHEN '39' THEN 1ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 920 ms.goDBCC DROPCLEANBUFFERSgoDECLARE @start datetimeSELECT @start = getdate()SELECT SUM(CASE WHEN lasttwo LIKE '[349]9' THEN 1 ELSE 0 END)FROM realthingSELECT datediff(ms, @start, getdate()) -- 1466 ms.Thus, when using the char(2) column LIKE is slower despite that thereis only one WHEN condition. So indeed it seems that right(realta, 2)is computed thrice in the first test.Another funny thing is the actual results from the queries - they aredifferent. When I ran:select count(*) from realthing where lasttwo <> right(realta, 2)The result was about half of the size of realthing! I can't see thatthis difference affects the results though.Now, your article had a lot more tests, but I have to confess thatyou lost me quite early, because you never discussed what is theactual problem. Since you are working with floating-poiont numbersthere is a great risk that different methods not only has differentexecution times, but also gives different results.--Erland Sommarskog, SQL Server MVP, Join Bytes!Books Online for SQL Server SP3 athttp://www.microsoft.com/sql/techin.../2000/books.asp
In a previous post, someone helped me with creating stored procedures, and I am grateful because I am transitioning from the Access World. Anyway, I get an error at .ExecuteNonQuery in visual studio 2005 when I run the following code: Dim strsql As String Dim strconn As String strsql = "sp_Roster" strconn = "server=xxxx; user=xxxx; pwd=xxxx; database=xxxx;" With comm .Connection = New SqlConnection(strconn) .CommandText = strsql .CommandType = CommandType.StoredProcedure With .Parameters.Add("TeacherID", SqlDbType.Char) .Value = "DawsMark@aol.com" End With With .Parameters.Add("ClassID", SqlDbType.Int) .Value = classid End With With .Parameters.Add("sID", SqlDbType.Int) .Value = ssID End With With .Parameters.Add("sLastName", SqlDbType.Char) .Value = lastname End With With .Parameters.Add("sFirstName", SqlDbType.Char) .Value = firstname End With With .Parameters.Add("sMiddleName", SqlDbType.Char) .Value = middlename End With With .Parameters.Add("Student", SqlDbType.Char) .Value = fullname End With With .Parameters.Add("Password", SqlDbType.Char) .Value = password End With .Connection.Open() .ExecuteNonQuery() With comm.Connection If .State = ConnectionState.Open Then .Close() End If End With End With The error was: Error converting data type char to int. The stored procedure in sql server was as follows CREATE PROCEDURE sp_Roster -- Add the parameters for the stored procedure here@TeacherID varchar(50),@ClassID int,@sID int,@sLastName varchar(50),@sFirstName varchar(50),@sMiddleName varchar(50),@Student varchar(50),@Password varchar(50)ASBEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.

This is strange because this code worked perfectly when connecting to Access and when I used oledb. So how is it the code's problem? Is the stored procedure causing the error or the code. Can someone please help. thanks. <Edited by Dinakar Nethi> Please mask your useird/pwd info in the connection string when posting to a public forum like this </Edit>
I would like to write a fun or stored procedure to do some operation. It require me to know that what category is currently belong to certain people(people_table: category_table1 to Many)However, when i use the select statement in stored proc, it return a set of result, not a scalar , therefore, i cannot use the variable to hold it. In addition, there are no array in SQL server.Question:1. Is there any way to hold the collection of result(like array)?2. Also, how to determine to use fun or stored procedure?(Since a integer is need to return by them)Thx
Every morning our sql server runs very slowly which means our log on page times out on a simple query. If we stop and start the sql server everything runs fine for the rest of the day until the follwing morning. the server is not used out of business hours excpet for a few very small and simple jobs to delete records, These all run to completion. Any help with this would be much aprreciated! Thanks. Rob
Hi .. i am SqL beginner. i having trouble output what i want from table. table contain 3 columns ________________________________ |(names)|(item)|(location)| 1.| Jimmy | pizza| TX | 2.| Joe | ball | CA | 3.| Joe | ball | WA | 4.| Jim | shoes| AZ | ________________________________
i try to select all records out from this table. but column 2 and 3 contain same information in names and item only different is location. how can distinct one of them?? and display like the below, please advise.

tblDocumentApprovals userID INT documentID INT approvalDate DATETIME
If I want to get a list of documents, and the users who've signed them off (if any), I'd do something like:
SELECT [tblDocuments].[documentName], [tblUsers].[userName ], [tblDocumentApprovals].[approvalDate ] FROM [tblDocuments] LEFT JOIN [tblDocumentApprovals] ON [tblDocumentApprovals].[documentID] = [tblDocuments.id] INNER JOIN [tblUsers] ON [tblUsers].[id] = [tblDocumentApprovals].[userID]
...which is lovely. Except - I don't want a row returned for each user that's signed it off. I want one row for each document, with a field containing a list of the people who've signed it off.
I know that it's bad design. I was reading an article only yesterday on how they're putting this kind of thing into the latest version of Access, and how it's a bit of a kludge. But it'd really, really help me.
the msdn article explains how to input new data to a databse and return the primary key of the inputted row. It works perfectly. However, it explains how to insert a value, but there is a problem. It seems to set the value to be submitted in the VB code, instead of having the value be the user's input in the textbox. Look for the following line in the code below: newRow("ClientFileNumber") = "ClientFileNumber" It inputs "clientfilenumber" instead of what is actually inputted in the texbox. Does anyone know how to bypass this, to not have the words "clientfilenumber" inputted?Dim sqlconn As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Client.mdf;Integrated Security=True;User Instance=True") Dim catDA As SqlDataAdapter = New SqlDataAdapter("SELECT * FROM Orders", sqlconn) catDA.InsertCommand = New SqlCommand("JobInsert", sqlconn) catDA.InsertCommand.CommandType = CommandType.StoredProcedure catDA.InsertCommand.Parameters.Add("@ClientFileNumber", SqlDbType.VarChar, 50, "ClientFileNumber")Dim NewJobNumber As SqlParameter = catDA.InsertCommand.Parameters.Add("@Identity", SqlDbType.Int, 0, "OrdersID") NewJobNumber.Direction = ParameterDirection.Output
sqlconn.Open() Dim catDS As DataSet = New DataSetcatDA.Fill(catDS, "Orders")
Dim newRow As DataRow = catDS.Tables("Orders").NewRow() newRow("ClientFileNumber") = ""catDS.Tables("Orders").Rows.Add(newRow) catDA.Update(catDS, "Orders")

An internal licensing review is being carried out at my site for the first time since I joined. I have been asked to confirm that development SQL Server instances have been installed from MSDN installation disks and production instances from non-MSDN disks. I understand that serverproperty('licensetype') will show me this information in SQL Server 2000, and I am (perhaps incorrectly?) assuming that a result of "DISABLED" means MSDN was used for the installation.
In SQL Server 2005, i believe the installation does not record the necessary information in the registry, meaning serverproperty('licensetype') is of no use.
Is the question i've been asked impossible to answer? Is there any way I can find out if MSDN disks (or network copies of them) were used to install a SQL Server 2005 instance?
We use MSDN SQL 2000 , the enterprise edition for our development servers, which have always had 2GB RAM. Now they are bringing in a Win 2003 Enterprise with > 12GB RAM . They want SQL SERVER 2000 to use AWE memory up to 12GB . Is there any limitation on MSDN Ent. Edition using more memory.?
