Property Value
The string containing list of key field names separated by semicolon.
The following example demonstrates how UPDATE and DELETE statements are generated.
public void UseKeyFields(string connectionString) {
DB2Connection conn = new DB2Connection(connectionString);
conn.Open();
DB2DataAdapter adapter = new DB2DataAdapter("SELECT * FROM Dept", conn);
DB2CommandBuilder commBuilder = new DB2CommandBuilder(adapter);
commBuilder.ConflictOption = ConflictOption.OverwriteChanges;
commBuilder.KeyFields = "DeptNo, DName";
string updateComm = commBuilder.GetUpdateCommand().CommandText;
string deleteComm = commBuilder.GetDeleteCommand().CommandText;
Console.WriteLine(updateComm);
Console.WriteLine(deleteComm);
conn.Close();
}
Public Sub UseKeyFields(ByVal connectionString As String)
Dim conn As DB2Connection = New DB2Connection(connectionString)
conn.Open()
Dim adapter As DB2DataAdapter = New DB2DataAdapter("SELECT * FROM Dept", conn)
Dim commBuilder As DB2CommandBuilder = New DB2CommandBuilder(adapter)
commBuilder.ConflictOption = ConflictOption.OverwriteChanges
commBuilder.KeyFields = "DeptNo, DName"
Dim updateComm As String = commBuilder.GetUpdateCommand().CommandText
Dim deleteComm As String = commBuilder.GetDeleteCommand().CommandText
Console.WriteLine(updateComm)
Console.WriteLine(deleteComm)
conn.Close()
End Sub
