DataSource Controls :: How To Ensure That Some Records Are Not Picked Using Sql
Apr 23, 2010
I am developing web applications using csharp. How can I ensure that some records are not picked using sql. I have a table with records and its content differ from each other dot ".". Table is as follows
Student1 Details2 Details2
1 Musol School Books
2 Musol School Books.
3 Golpp Temo Books
4 Golpp Temo Books.
How can I select records without dot "."at the end only. For example
1 Musol School Books
3 Golpp Temo Books
I have used sql but I am not getting it. My sql is as follows
When a user enters a value I want to check against the other values in the database before allowing the record to be inserted.
It is a nvarchar type column.
Is it best to use a unique constraint (if so, how) or what would be the way to programatically check to make sure this name does not exist. It is not a username, just a name value that will be used in routing.
When I try to run the simple page I receive the following error
Server Error in '/' Application.the data source for GridView with id 'GridView1' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.
Here is my page code

Suppose we have a website with 10,000 viewers each second. And we want to insert the viewer's information to the SQL database. So we must insert 10,000 records to the SQL each second. And it may take long time to do.
CREATE PROC [dbo].[SP_NEWS_SELECT] ( @NB_NEWS int, @ID_NEWS int, @DT_PUBLICATION datetime ) AS SELECT TOP @NB_NEWS * FROM [REP_CLI].[S_ETATS].[T_NEWS] ORDER BY [DT_PUBLICATION] ASC
im learning t-sql, infact i needed its while-loop to loop through records of a table, i found this code in some book:
[Code]....
i understand here that setting the rowcount variable to 1 will force the select statements to return only one record, do all above select statements return one record only?
if the underlined select statement returns one record everytime it is executed, isn't it supposed to return the same first record of the table everytime? is there a better way to loop through a table's records?
I'm trying to query records from a db using a date. But somehow the db doesn't return records.
The datetime collums have the data stored in this format in the db as datetime :
12-Apr-10 12:45:12 AM The string a have available is in this format : 12-Apr-10
I need to somehow strip the time part of so i can use my date string in the query.
When i use the below method the database converts the datetime to a rounded date (12-Apr-10 12:00:00 AM). But when i query for that date i still get no results.
I tried this:
SELECT ID, PerformedBy, SystemId, ServerId, CAST(FLOOR(CAST(CreateDateTime AS FLOAT)) AS DATETIME) AS Expr1, Reason, Action, Summary, EnteredBy, Collumn1, Collumn2 FROM Changes WHERE ('Expr1 = '12-Apr-10 12:00:00 AM')
What is the best method in T-SQL 2008 for extending a table's records with the criteria of 'repeating' all fields but the Primary KEY e.g. Consecutive Date for the previous n Records.
So you have for example 7 records (Easy...2 Fields. Date and nvarchar) with th Date runing from Jan-01 to Jan-07
We want to extend the table by 21 records...so
Record 1,8,15,22 will look identical apart from the DateField.
Record 2,9,16,23 will look identical apart from the DateField. etc...etc..
I have tried a number of methods ...all coming up short....
New to all this and trying to work out the best of doing what I need to do.
I have a little ddl with a list of 100 or so different items in it. The person clicks the button and it gets logged into a table (ItemLog).
So then where I become unstuck is I want:
A total number of records.A total number of records for each of the items in big long list.Then be able to break the records down by date.... Would I need to write out a lot of count statements in sql?
I have code for inserting a record into the db, it works fine from the admin part of my website but when i put it on the customer side duplicate records are inserted into the db, any ideas? I cant for the life of me see why. I have just also noticed that when i add the claim the first time it adds the duplicate entry, if i press the button again it only adds the entry once, if i refresh the page add the info again, 2 entries, click add again 1 entry?
I want to display all duplicate records in the table.My query has to fetch all the records which are duplicate(First Name or Last Name).Also I want the ability to also pull names where there might be a middle initial placed in the end of the first name field, (i.e., "Maria Z. " vs. "Maria") as well.
Table:
ID FirstName LastName 1 Zach H Hoffman 2 Zach Hoffman 3 Troy Hoffman 4 Shawn Livermore 5 Prem S 6 Jony Hoffman H 7 Zach Modan
I need the query to filter.........
ID FirstName LastName
1 Zach H Hoffman 2 Zach Hoffman 3 Troy Hoffman 6 Jony Hoffman H 7 Zach Modan
I hope this example will give you clear idea..... I need SQL Query to perform this
Given an XML id list pulled out from a User Profile, how can we best program to use that list to retrieve text records from a SQL table and populate a dropdown list which contains ids from the XML list and text values from the SQL table.
My application is written VS 2008 and .net framework 3.5. Sometimes when a user picks a value in the drop-down menu, this action closes the whole window. I cannot repeat this error on my box, but one of my users gets it consistently. Have anyone ever experienced anything like this?
