DataSource Controls :: Set Up SQL Table Columns To Have Multiple Values?
Mar 9, 2010
Is it possible in to set up an SQL table column to have multiple values? Or would I have to put my values into a new table and link it to the original one?
I've requirement where user can enter multiple columns like first name, lastname, email, age, sex fields and insert them into database.on my frontend aspx page, i'll be showing a single row initially with 5 text boxes(first name, lastname, email, age, sex) and a button to add more columns. when user clicks on add more, another 5 textboxes will be shown and then i'll be taking 5 + 5 (textbox values) and comma seperate them and need to insert into a table with primary auto increment key ID and the remaining 5 columns(firstname, lastname, email, age, sex). I previously worked on the same requirmeent but with only single column. Now i need to insert for 5 columns, How can i do this? Below is my stored proc which i used for single column insertion.
I am creating an online employment application, and instead of creating a table with 20 columns for job duties that may or may not receive values, I simply want to create 3 columns
ApplicantID EmployerName (Name of Work history Employer) JobDuty
I want to create a form on a page with 10 textboxes so the applicant can type in some job duties they had at that job.
Is there a way in C# or SQL to then cycle through and insert the textbox values as separate rows?
I'm just wondering if anyone can assist me with this gridview problem
I have this Sql statement that outputs a gridview like this
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
* These columns are placeholders
I want to include a footer total that looks like
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
Final Total 4
Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.
I am returning a dataset from a method and trying to set one of the columns as Primary Key.
CategoryList.Tables[0].PrimaryKey = new DataColumn[] { CategoryList.Tables[0].Columns["CategoryNodeId"] };
Interestingly it gives me this error at run-time, These columns don't currently have unique values.
Now I perfectly know why this error should error, but there are no duplicate keys in this data column. I broke the code in between and bound the dataset to gridview to check if this column contains any duplicates and this is not the case. Here is the result set underneath. Have a look at the first column 'CategoryNodeId'.
CategoryNodeId CategoryId Name ParentCategoryNodeId [code]...
is there a SQL statment i could write that would sum each column and allow me to then access each sum individually
i.e
Dim objCmd As New OleDb.OleDbCommand("SELECT SUM(expression) FROM orderForm WHERE OrderDate=@OrderDate", objConn)
is there anything i can replace expression with such that all the columns in orderForm could be summed and returned as one record
or is there a way to replace expression with something that would allow me to just keep changing the paramater so i could continuously reexectute the same command w/o having to create a new command for each column
I have created a table in my SQL database that has a primary column (Title) and another column named Callsign. How can I access the table row that has a certain title and Callsign using C# in a web page event handler?

Dim ParentCol As New DataColumn, ChildCol As New DataColumn
how I add multi-column constraint to a table in SQL2005 ?
I want to prevent a user from entering a row in the table where Column_A = 1, Column_B = 2 etc where there is already a row where Column_A = 1, Column_B = 2.
This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords FROM (Merchandise) WHERE Keywords LIKE @term
The only other thing I can think of the gain this level of functionality would be to combine them into a new table.
I have just started using LINQ with VS2008. I have added extra columns to my table, saved the changes, but class ClassName.Designer.CS didn't get updated. What do I have to do to updated the class? Do I have to do it manually, or is there a way to automatically synchronize tables and ClassName.Designer.CS?
I wanted to know if it is possible to dynamically add columns to a table in the Database?I know how to create a table dynamically in the DB the code for it is given below, howver I do not know, how do I add columns to it dynamically.
Dim NewTable As String = "CREATE TABLE Dynamic " + " (" + " job_id smallint" + " IDENTITY(1,1)" +[CODE].....
I have an SQL table called tbl, im trying to add the columns A, B and C to it.
When i execute the command :
addcolumns = "ALTER TABLE SqlCreatedTbl ADD A char(50) ;"; cmd = new SqlCommand(addcolumns, conn); conn.Open(); cmd.ExecuteNonQuery();
The column is added perfectly and i can see it in the table !
However, when i try to add multiple columns, it does NOT work, it gives me an error..
the command im writting for adding multiple columns is the following:
addcolumns = "ALTER TABLE SqlCreatedTbl ADD ( A char(50), B char(50), C char(50) );";
the debugger highlights the line : cmd.ExecuteNonQuery(); and throws the following exception: Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near '('.
I have a gridview that shows, for example, a baseball team's statistics. It's a standard sports stats grid - the rows show statistics for each player and the columns show the specific stat for the each player.
Easy enough so far. But what I would then like to do is style (highlight or bold) the Max or Min (the team leader) of each stat column. For example, Player A may only lead in one or two categories, so we cannot style the entire row. If Player A just leads the team in strikeouts, I just want to style the number of strikeouts he had (THAT cell only).
What's the best way to handle this? Make SQL Server do all the work and in effect, rank EVERY stat of each player, effectively doubling the number of columns (e.g. col: AB, col: ABRank). Or do I let the rowdatabound event of the gridview handle this?
If I chose the latter, I think I would get the Max of every statistical category from the datatable before binding (e.g. store them in a local variable) then on rowdatabound, if they match the value, apply the style.
I have a table with a lot of records - it has a column called CallID I have another table with no records, but one that also has a CallID column I want to insert all the values from the CallID column in the first table into the CallID column of the second table.
I am retrieving a column from a table using an SqlDataSource in ASP.NET/C#, which contains multiple 'values' separated by commas. I'd like to be able to separate this values into multiple columns in my GridView, and also allow them to update them. Is this easy to accomplish?
SELECT ClientMaster.ClientName,* FROM ProjectMaster LEFT JOIN ClientMaster ON ProjectMaster.ClientCode=ClientMaster.ClientCode WHERE ProjectMaster.RefCode IN (@refcode) AND ProjectMaster.ProjectStatus=@status
@refcode should be able to contain multiple values but how should I pass value to the parameterized query?
I have tried many ways such as @refcode = 'VALUE1','VALUE2', @refcode = VALUE1,VALUE2 but to no avail?
