Jun 19, 2007
Is me again,and now i facing problem to retrieve a single record from the database.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim user As String
user = TextBox1.Text
Dim varpassword
Dim mydata As SqlDataSource

What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
Hi, I have a SqlDataSource(named SQLDS1) which retrieves 4 value from database(ProductName,ProductCost,ProductID). I Have a DropDownList(DDL1) control and its DataSource SQLDS1.

First I want to say thanks to the folks how have helped me over the past week or two. I'm missing a crucial piece of insight. How do I read a single piece of data from a SqlDataSource which only hold one row of data into a declared variable? string zUserName = SqlDataSource.(get the value in the row that is labeled UserName) It really doesn't matter to me whether it is an SqlDataSource or some other data container that hold the data I've selected. My goal is to be able to read some data from some predefined datasource into a declared variable. If I am approaching this problem in the wrong way any advice or article links you could give me would be grealy appreciate. Thanks, Bill
I I have a GridView with paging enabled which is bound to a SqlDataSource. I'd like to be able to tell the user how many records were returned in total by the SqlDataSource. Is there any way to do this without re-running the query?

Hi,I'm trying to create a registration page that I've divided into multiple pages (first page for basic details, next page for address, etc.). I insert the record in the first page, and update it in the other pages. I pass the newly created ID to the other pages using the Page.PreviousPage property. In the second page, I have the SqlDataSource configured as "SELECT * FROM [Table] WHERE ID = ?", and the UpdateCommand is "UPDATE .... WHERE ID = ?". In Page_Load, I am updating the SelectCommand to "SELECT ... WHERE ID = " & intID, and the UpdateCommand similarly. The I do a dtlsvw.Databind()But when I go to the next page (the newly created ID is being passed properly), the update doesn't do anything. The new record doesn't contain the values in the detailsview. Can somebody help me out? Thanks,Wild Thing
,I am creating a database where each record is required to have a twin record in the database.These is a type a value and a type b value and both must be present for the record to be valid.
Customer_ID, Order_Type, Product_Code 54, a, 00345 54, b, 00356
Is this something that would have to be done programmatically, or is it possible to create a constraint of some sort to ensure this?
This one is driving me nuts. I've issued a very simple statement to delete a single row from a table. It appears that when I execute it in SQL Query Analyzer the CPUTime spikes and holds one of the CPUs on the box pegged at 100%. I've let this thing run for over a day, and it's not deleting the one damn record. Any thoughts? :confused: :confused: Here's the command I'm executing:
DELETE FROM Invoices WHERE InvoiceID = 153345
Running SELECT * FROM Invoices WHERE InvoiceID = 153345 returns only a single record as it should. InvoiceID is the PK in this table. Any and all help is greatly appreciated. I've rebooted the server, but to no avail. Same thing happens after a reboot.
Can you please assist me on how to get the 2nd record in case there are3 or more records of an employee, the query below gets the MAX and MINBasicSalary.

I only need one recordwhich should be the Basic Salary before the 1st record on a DESC order.Please add the solution to my 2nd Select Statement which get theOLDBASIC salary Thanks ...SELECT TOP 100 PERCENT E.EmployeeNo, E.LastName, E.FirstName,E.SectionCode, E.Department, E.DateHired, E.Remarks,(SELECT TOP 1 ([BasicSalary])FROM empsalaries AS T14WHERE T14.employeeno = E.employeeno AND startdate BETWEEN @FromDate AND@ToDateORDER BY startdate DESC) AS NEWBASIC,******************************* BELOW I SHOULD ALWAYS GET THE BASICSALARY PRIOR TO THE 1ST RECORD AND IN A SINGLE ROW ???(SELECT TOP 1 ([BasicSalary]) (FROM empsalaries AS T14WHERE T14.employeeno = E.employeeno AND startdate BETWEEN @FromDate AND@ToDateORDER BY startdate ASC) AS OLDBASICFROM dbo.Employees EWHERE CONVERT(VARCHAR(10),E.DateHired, 101) BETWEEN @FromDate AND@ToDate ORDER BY E.LastName
Can someone please tell me which type of Isolation Levels in the Database Engine to avoid the above side effects respectively.
For Record Locking issue: Example, two editors make an electronic copy of the same document. Each editor changes the copy independently and then saves the changed copy thereby overwriting the original document. The editor who saves the changed copy last overwrites the changes made by the other editor. This problem could be avoided if one editor could not access the file until the other editor had finished and committed the transaction.
For the above example, is it possible to do like this way: Editor 1: SELECT and Lock a record Editor 2: Before SELECT the record, check for the record whether it is locked or not. If it is not lock, then the record can be selected
I am using ASP.NET 3.5 with SQLDataSource, when a record is inserted is there a way to retreive the newly created GUID value in a field? I am currently using SELECT @NewID = SCOPE_IDENTITY() to retreive the newly created record unique ID field, but I need the secondary field GUID field's value instead in this case. Thank you.
I am using a drop down list box to select values from an SQL 2000 DB. I have put a record into the table which says"...Select Item"I used the dots so that It will apear at the top of the list and therefore display at startup. I also have a gridview to allow users to edit and delete from the same table.I am worried that a user may accidently delete the "...Select Item" row from the table.Can anyone think of a way round this? Is it possible with SQL Server 2000 to stop a single record from being deleted?Any help would be most appreciated.ThanksPaul
HiIs it possible to return the results of a query so that instead ofhaving say 10 rows its concatenated, egMy query returns 'M' 10 times, can this be returned as 'M M M M M M MM M M'?ThanksLee
a record value instead of aggregated value with GROUP BY?
Assume that I have a PRODUCT_COMMENT table defined as below. It logs the multiple comments for products. A product may have multiple comments logged at different time.
Code Block
CREATE TABLE [dbo].[PRODUCT_COMMENT]( [COMMENT_ID] [int] IDENTITY(1,1) NOT NULL, [PRODUCT_ID] [int] NOT NULL, [COMMENT] [nvarchar](50) NULL, [UPDATED_ON] [datetime] NOT NULL, CONSTRAINT [PK_PRODUCT_COMMENT] PRIMARY KEY CLUSTERED ( [COMMENT_ID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]
GO ALTER TABLE [dbo].[PRODUCT_COMMENT] WITH CHECK ADD CONSTRAINT [FK_PRODUCT_COMMENT_PRODUCT] FOREIGN KEY([PRODUCT_ID]) REFERENCES [dbo].[PRODUCT] ([PRODUCT_ID]) GO ALTER TABLE [dbo].[PRODUCT_COMMENT] CHECK CONSTRAINT [FK_PRODUCT_COMMENT_PRODUCT]
I would like to use the following SQL statement to get the latest comments for all products.
Code Block
SELECT PRODUCT_ID, COMMENT, UPDATED_ON FROM PRODUCT_COMMENT GROUP BY PRODUCT_ID HAVING UPDATED_ON = MAX(UPDATED_ON)
But this leads to the following error:
Code Block
Column 'PRODUCT_COMMENT.UPDATED_ON' is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause.
I have imported a table into SQL Server from a legacy program. Each record has a repeating sequence of similar fields. (Ex. Accnt1, Assesed1, Paid1, Accnt2, Assesed2, Paid2, etc.) I would like to take a single record and put data from these fields into a table that has the columns Accnt, Assesed, and Paid. I am doing this for easier use in a program I am developing in VB 2005. Can this be done in SQL or do I need to have help from some VB code? If it's possible, what might the SQL look like?
Hi,I have an updatable DataGrid linked to a SQLDataSource in a web site developed using VS2005. Update works fine unless a value in the existing row is Null. Only one column in the database allows nulls.Putting a debug stop in the SqlDataSource1_Updating event, I checked the parameter value in the Immediate window and got the following result:?e.Command.Parameters(16){System.Data.SqlClient.SqlParameter}System.Data.SqlClient.SqlParameter: {System.Data.SqlClient.SqlParameter}DbType: Int32 {11}Direction: Input {1}IsNullable: FalseParameterName: "@original_FiresolveJobNo"Size: 0SourceColumn: ""SourceColumnNullMapping: FalseSourceVersion: Current {512}Value: NothingIs there a property I can set to generate a suitable Null check clause for the Update statement?Many Thanks,Keith.
that above was my solution, get the relatedterms information and comma separate, and then put a # and get all the ids comma separate them and then put the in one field. then I can later parse it in the client
this does not seem like a very good solution ( or is it?) If posible it would be nice to get something like this
TermID, Term, RelatedTermsInformation 1 test RelatedTermsTwoDimentionalArray
but I am not sure how this idea could be implemented using the capabilities of SQL.
my other option is have the client make one call to the database to get the terms and then lots of another calls to get the relatedTerms, but that will mean one trip to the DB for the list term, and one call for every single term found.
I have the following table. There are eight section IDs in all. I want to return a single row for each product with the various section results that I have information on.
Hi, I have a difficult case that I need to solve. I will try to be the very clear explaining my problem:
I have a sql query which brings me many records. This records have a column in common which have the same value (COL1)
There is a second column (COL2) which has different values bewteen these records. I need to concatenate values from the second column in records with same value in COL1. And I need only one record of the ones that have the same values. If two records have the same COL1 value, only one row should be in my result.
Let me give you an example: COL1 COL2 RECORD1 1-A HHH RECORD2 1-A GGG RECORD3 1-B LLL RECORD4 1-B MMM RECORD4 1-B OOO RECORD5 1-C NNN
Me result should be:
COL1 COL2 RECORD 1-A HHHGGG RECORD 1-B LLLMMMOOO RECORD 1-C NNN
It is clear what I need? I dont know if I can solve it through sql or any function inside SSIS. Thanks for any help you can give me.
I'm trying to pull all records from one table and just a single record from another. I have this join, (see below). It works ok, but the problem is if a blog record doesn't have a corresponding image record it doesn't return. The end result should be the blog record and a single corresponding image record. But always a blog record.
SELECT U.UserFamilyName, F.FamilyName FROM Users U LEFT JOIN User_Friends F ON U.UserID = F.UserID WHERE U.UserName = ‘JOHN’
How do I adjust my query to select just the very first record from Users_friends, I want only the top first one.And if there are no friends how can I return an empty string instead of Null.
What is the most efficient standalone .NET class that can hold a single disconnected record? The class must also retain column names, but other schema is not relevant (.NET data type is sufficient).If I understand System.Data.Common.DbDataRecord, it provides an interface on a DbDataReader, and has no storage of its own.I'm familiar with DataSet, is that the only .NET-standard class to do this? Thank you,Shannon

Hello, In SQL Server Management Studio (2005), 'Open table' command or a SELECT query displays table rows in a grid (or text).Please tell how to view a single row at a time i.e. all only ONE row is displayed at a time (evenly arranged to cover the screen). This feature (Single record view) is available in other database client like TOAD. Thank You
I am using DTS and VBScript in DataPump tasks in order to transfer large amounts of data from text files to an SQL database.
As the database uses a normalized schema, there is often the case of inserting multiple records in a destination table from various fields of the same record of the source text file.
For example, if the source record contains information about goods sold like date, customer, item code, item name and total amount, and does so for a maximum of 3 goods per sale (row), therefore has the structure:
I have tried using a datapump task and VBScript, and I guess it has to do with the DTSTransformStat_**** constants, but none of those I used seems to work
