View 1 RepliesI want to issue an INSERT command for an SQL Server table using DataAdapter without first issuing a SELECT command. Could anybody send me lines of code to handle this? Also how do i manage INSERT into selective table columns (I have 10 columns but i only want to update 2 of them)?
View 2 RepliesI want to know how I could fix the following. I essentially have two almost identical SQL functions and want to combine them into one. The only difference between the two functions is the SQL Command text that is being used. Here is a brief idea of what I have unsuccessfully tried thus far:
[Code]....
I receive no compilation errors, but the exception is thrown and table is not filled. I have a feeling that I am overlooking something obvious.
I want to use parameter in SQL command, Which the following code is better and why?
string id= getId();
SqlCommand cmd1 = cn1.CreateCommand();
cmd1.CommandText = " INSERT INTO std(idStd) VALUES (idStd=id) ";
cmd1.ExecuteNonQuery();
string idF = getId();
SqlCommand cmd1 = cn1.CreateCommand();
cmd1.CommandText = " INSERT INTO std(idStd) VALUES (idStd=@id) ";
cmd1.Parameters.AddWithValue(@id, idF);
cmd1.ExecuteNonQuery();
No matter what I do I keep getting the error that my input string is not valid and that the system cannot convert a string to a double. I have a table with two fields, both are defined as nvarchar(25). My command text is:INSERT INTO OtherProducts VALUES ('Sample','Test') am using Visual Web Developer. This is as simple as it gets. I have tried parameters as well.

I have a detailsview which I am populating using a SQLDATASOURCE, which is bound to a table in a SQL db. Because the number of columns in the table will change, I am using SELECT * from [TABLENAME] to populate the view, this works fine.
My problem is that I need to also be able to update the table and I thought the best way was to generate the updatecommand in the code behind. This is no problem, code is as follows:
[Code]....
But the next stage is to create the relevant parameters for the update command. Does anybody have any thoughts on this? All of the information I have found for the updateParamater reference knowing the final value.
What I really need to do is the code behind equivalent of
<asp:Parameter Name="PARAMETERNAME" Type="Int32" />
Not sure whether this is possible.
see this code.

Is it possible to perform an update command which performs addition using a value from a textbox? For example: User inputs a number into TextBox1 (I use regular expression validation to ensure this is an integer).

Basically if the user inputs 5 into TextBox1, I want the update command to subtract 5 from that user's ballance.

I have a problem and I could not solve it. Hope you can write a sample code for me. I have a Microsoft Access database, and in asp.net website, i draw a grid view on the design page. I also configure the source data access. It works, but display all the data in the database. i want to display all the data which is related to John. sql = "select username, customer_name, phone from db where username = John" how do i configure the data grid view?
View 3 RepliesHow to start at a specific record and returning only the next 5 records with T-SQL command
[Code]....
That is my concatenated SQL statement but it obviously does not work because it only looks at the top 5 records in the entire table instead of what I intended which would be to look at the top 5 records starting with the record where PostNumber equals the value of lastPost. I have been searching for a T-SQL statement that will allow me to do this but I can't find one.
I am using VS 2008.I am building a datatable of records to be inserted into a SQL Server 2005 table.
The program loops through this table and builds a SqlParameter for each DataColumn in the datatable. The SqlParameters are used in the SQL Insert statement.
The field I am having a problem with is of type 'bit' in the database table and has no default value and cannot be nulls. The field is called 'Active' The meaning of this field in the application is Boolean i.e True or False. When inserting the record, I wish to default the field to "False".
When I define the columns in the datatable I am forced to use the following code to build the datatcolumn containing the boolean field i.e. dtcActive.DataType = GetType(Boolean) as there is no GetType(Bit)
Dim dtcActive As New DataColumn("Active")
dtcActive.DataType = GetType(Boolean)
dtcActive.Unique = False
dtcActive.AllowDBNull = False
dtcActive.DefaultValue = False
dtProviderDayDetails.Columns.Add(dtcActive)
However, when I build the SqlParameter I am forced to use this:
If field.ColumnName = "Active" Then
prm.SqlDbType = SqlDbType.Bit
prm.Value = "False"
End If
This is because there is no SqlDbType.Boolean. The problem I have is there is no value I have been able to give the SqlParameter that is accepted by the Insert statement. It complains that the boolean field cannot be null on Insert.

I need to display a single field from an sqlserver table, do I need to use sqlDataSource ect. or is there a simpler way (like msaccess's LookUp) for single values.
I'm using the asp.net membership on my website. On the User Administration page i've got a GridView to show the details of the users on the site. As a datasource rather than just using the Membership.GetAllUsers function i've got a SQLDataSource as i need to display user information from 3 different tables. I'm trying to add a delete button to the GridView. I'm setting the Membership's UserName as a DataKey and then using the RowDeleting event to call Membership.DeleteUser for the appropriate UserName. This works fine and the user is deleted however i then get an error showing up that "Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified."
I don't want to use the SqlDataSource for deleting as i've already done it using the Membership. How can i stop it from trying to do this? Here is the cut-down that i have if you're interested. The selectcommand in the sqldatasource was auto-generated by it.
