[Firebird-net-provider] Bulk copy
Hi Guys,
Does anybody know how to make a bulk copy of a table from one database to
another using Fb Net provider?
I am trying to achieve this goal using something like this:
FbDataAdapter sourceDA = new FbDataAdapter("SELECT * FROM TEST_TABLE",
fbSourceConn);
DataSet ds = new DataSet();
sourceDA.Fill(ds, "TEST_TABLE");
FbDataAdapter targetDA = new FbDataAdapter("SELECT * FROM TEST_TABLE",
fbTargetConn);
FbCommandBuilder fbCb = new FbCommandBuilder(targetDA);
targetDA.InsertCommand = fbCb.GetInsertCommand();
foreach(DataRow dr in ds.Tables["TEST_TABLE"].Rows)
{
/// Change the state of the row
dr.SetAdded();
}
targetDA.Update(ds, "TEST_TABLE");
The problem with this approach is that FbDataAdapter.Update() is too slow.
It takes almost 1 hour to copy aprox 500.000 rows.
Is there a faster way to do this? or am I missing something?
Thanks in advance
Eduardo

Can you try to wrap the inserts inside a single ( or several ones ) transaction ?? - This SF.net email is sponsored by: Microsoft Defy all challenges.

With .net provider? AFAIK QLI (old tool, like isql) can do this as
fast as possible.
BTW I'll try to use DataReader and not filling dataset and pump it
into in one foreach loop.
Using the dataset is some unnecessary overhead.

Carlos, Wrapping the process in a single transaction reduced the time to only 4mins.

Is there a way to use a single transaction with multiple database connection?

In Firebird yes. FB has support for 2PC protocol. But with .net
provider you can't use this.
