I am getting the following error when i try to insert the record.
Operation must use an updateable query.
[code]....
I'm trying to do a very simple update in Access:
[Code]....
and am getting this error. Both contact_information and temp_contact_information are tables. The subquery
[Code]....
works fine by itself, and if I replace the subquery with the result of the subquery, for example:
[Code]....
it also works. What the heck?
I executed the following sql command, and got error "Operation must use an updateable query.".

The database is access 2003. The tables are T1 (code (key), n) and T2 (code(key),num). Why do I get this error and how do I solve it? EDIT: Found solution somewhere else.

I'm just stuck as I can't work out the best way to do it,
in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.
View 1 Replieshow can i select a record from A table and insert into B table using linq?
View 2 RepliesI have a LINQ query like this:
var query1 = from x in db.FaqCategories select new { x.CategoryId, x.Category };
What I would like to get is a query with an empty record
var empty = new {CategoryId="", Category=""};
on the very top of query1. I think this can be accomplished by using the union operator, just don't know how.

View 1 RepliesTrying to check if an insert of a new record into an SQL table is happening successfully. I can see that the insert is occuring OK but am not getting the verification to happen.
I'm a little new to C#, I'm thinking it may be in the syntax I'm using in my method in the .cs file line 45. Can't seem to fix it right though.

How I write query for this. When user click submit button record will saved to both tables.
i have a problem executing an insert query. whenever i try to insert i have an exeption telling me it cant execute because a record needed in another table; where i select a value form that other table according a listbox, and then insert it into this table. here is a sample of my code:
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|emp2.mdb");
int a = 0;
conn.Open();
string sqlcmd = "select id from nationality where descreption = '" + DropDownList1.Text + "'";
OleDbCommand readNatCmd = new OleDbCommand(sqlcmd, conn);
OleDbDataReader readerNat = readNatCmd.ExecuteReader();
while (readerNat.Read())
{
a = readerNat.GetInt32(0);
}
readerNat.Close();
conn.Close();
string saveEmpcmd = @"insert into employee " + "(nationality) " + "values (@nationality)";
OleDbCommand objCmd = new OleDbCommand(saveEmpcmd, conn);
objCmd.Parameters.AddWithValue("@nationality", a);
conn.Open();
objCmd.ExecuteNonQuery();
conn.Close();
now, the form executes with no errors, but it catches an exeption caused by the ExecuteNonQuery funtion; here it is in details:
System.Data.OleDb.OleDbException: You cannot add or change a record because a related record is required in table 'nationality'. at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr) at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS

behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteNonQuery() at Default2.Button1_Click(Object sender, EventArgs e) in c:Documents and SettingsAdministratorMy DocumentsVisual Studio 2005WebSitesempDefault2.aspx.cs:line 305
when i remove the relation between the tables, the exeption isnt catched anymore, but the value stored in the employee table is 0 how can i solve this?
