insert large amount of records into access database

[ireallyneedtoknow2007]

hello i am using c# in visual studio 2005 and need to insert a large
number of records contained in a dataset into an access database. the
following is too slow. how can i update my DataAdapter with all the
rows(150000) at one time? thanks

foreach (DataRow row in ds.Tables[0].Rows)
{
DataRow dr = ds1.Tables["testtest"].NewRow();
dr = ds1.Tables["testtest"].NewRow();
dr["field1"] = row["field1"];
dr["field2"] = row["field2"];
ds.Tables[0].Rows.Add(dr);
ad.Update(ds1, "test");
}

With Access?

I don't think so.

At some point, you'll be running a 1 row by 1 row operation. Whether you do
it manually, or allow the dataadapter to do it for you.

You might write a Updateable Query, and call it, but it's still a "per row"
method.

If it were me, I wouldn't rely on the dataaadapter, ... at least right your
own code for the inserts.

.........

Switch to Sql Express 2005 and you'll have more options.
I have no idea what this is:

but maybe you can look into it.

I'm not really up to speed on Access, but try doing the ad.Update just one
time outstide the foreach. It should improve the speed.

foreach (DataRow row in ds.Tables[0].Rows)
{

}
ad.Update(ds1, "test");

Thank you, moving the update did the trick.
