View 5 RepliesDataSource Controls :: Columns Don't Currently Have Unique Values?
May 3, 2010I 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]...
unable to find a work around for now.
ADO.NET :: Accepting Unique Values Only: I Manage To Do It But Is There A More Elegant Way?
Sep 30, 2010I'll try to make this concise. Anyways, I'm trying to only allow unique data to my database. my database. What I did before adding the entry is to use a Search Query for the value of the txtbox
"SELECT IDnum WHERE IDnum = '" & txtID & "'"
Then compare it with that of the txtbox.
IF objReader("IDNum") <> txtID.textbox then add the entry Else Display a Warning.
in the above code, I can detect the when the user entered an existing value. however, If the user entered a NEW (unique) value an error is Raised "Invalid attempt to read when no data is present" I hit the wall with this.So what I did, Since I can detect Duplicates and have errors when entering unique value, I used the
ON ERROR GOTO statement: I did it like this.
On Error Goto errHandler
If objReader("IDNum") = txtID.textbox then
lbl1.text = "Existing Record"
objReader.close() [code]....
The Code does what I need but its kinda long, I bet there is an elegant way to do this.
Efficiently Finding Unique Values In A Database Table?
Feb 11, 2010I've got a database table with a very large amount of rows. This table represents messages that are logged by a system. Each message has a message type and this is stored it it's own field in the table. I'm writing a website for querying this message log. If I want to search by message type then ideally I would want to have a drop down box listing the message types that have come up in the database. Message types may change over time so I can't hard code the types into the drop down. I'll have to do some sort of lookup. Iterating over the entire table contents to find unique message values is obviously very stupid however being stupid in the database field I'm here asking for a better way. Perhaps a separate lookup table which the database occasionally updates listing just the unique message types that I can populate my drop down from would be a better idea.
The platform I'm using is ASP.NET MVC and SQL Server 2005

WCF Service Return And Array Instead Of A List <T>?
Mar 26, 2010In the web servce I say
public List<Customer> GetCustomers()
{
PR1Entities dc = new PR1Entities();
var q = (from x in dc.Customers
select x).ToList();
return q;
}
(customer is a entity object)
Then I generate the proxy when I add the service.. and in the reference.cd it say
public wcf1.ServiceReference1.Customer[] GetCustomers() {
return base.Channel.GetCustomers();
}
WHY IS IT AN ARRAY? I asked for a List.
