Devart.Data.MySql Namespace / MySqlDump Class / DisableKeys Property
Example

DisableKeys Property
Determines whether to add ALTER TABLE ... DISABLE KEYS clause before INSERT statements.
Syntax
'Declaration
 
Public Property DisableKeys As Boolean
 

Property Value

true, if ALTER TABLE ... DISABLE KEYS clause should be added before INSERT statements; otherwise, false. The default value is false.
Remarks

When inserting large blocks of data on large tables, setting this property to true makes the script generated much faster.

This feature is affects MySQL servers of version 4.0 and higher.

Example
This sample demonstrates dumping of two tables (Dept and Emp). The script is written to a file after the operation is complete. Performance of the script is improved by disabling the check of constraints.
public void DumpIt(MySqlConnection myConnection)
{
  myConnection.Open();
  MySqlDump mySqlDump = new MySqlDump();
  mySqlDump.Connection = myConnection;
  myConnection.Database = "Test";
  mySqlDump.DisableKeys = true;
  mySqlDump.Tables = "Emp;Dept";
  mySqlDump.Backup();
  StreamWriter stream = new StreamWriter("d:\\tmp\\mysqldump.dmp");
  stream.WriteLine(mySqlDump.DumpText);
  stream.Close();
  Console.WriteLine("Dumped.");
  myConnection.Close();
}
Public Sub DumpIt(ByVal myConnection As MySqlConnection)
  myConnection.Open()
  Dim mySqlDump As MySqlDump = New MySqlDump
  mySqlDump.Connection = myConnection
  mySqlDump.DisableKeys = True
  mySqlDump.Tables = "Emp;Dept"
  mySqlDump.Backup()
  Dim stream As StreamWriter = New StreamWriter("d:\tmp\mysqldump.dmp")
  stream.WriteLine(mySqlDump.DumpText)
  stream.Close()
  Console.WriteLine("Dumped.")
  myConnection.Close()
End Sub
