DataSource Controls :: Conditional SQL Command In VB?
Jan 3, 2010
I 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 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)?

I am stuck with conditional multiple eval declaration of navigateurl property of hyperlinkI want to bind the navigate url property depend on user selection and set its visible property based on NULL value in SQL databse at the same timeThe code that i have at the moment :
<asp:Hyperlink ID="Hyperlink1" runat"server" NavigateURL='<%#Eval("link1") %' Visible='<%#ISNull(databinder.eval(container.DataItem, "link1"))%>' </asp:HyperLink>
In the code behind i run function ISNull, which works fine returning either true or false depend on value, however it only works for single EvalI believe that i am looking for function code behind that returns the value of Eval, so if user selects Product1 i want link1 to be bound to navigateurl and set its visible property if link isnot null in database but if user selects Product2 or Product3 then i want the same hyperlink to display link2 or link3, set its visibility again based on null values from ISNull function

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.

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

How 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.
