When adding lots of records, do you still use INSERT INTO?

[Mike Hnatt]

My goal is to get data from an XML file into a couple of tables in an Access
database. The XML file is a little complex so I need control over what I do
(I can't just read it into a dataset).

The way I have it now is ennumerating through my XML file and for each
record, running an INSERT INTO SQL statement to put the values in the
database.

Is this going to be okay with 50 or so records (hitting the database with 50
or so INSERT commands for each record) or one of the other methods:

1) continue using an INSERT INTO statement for each record or
2) use an ADO recordset or
3) make a datatable from the XML, (but it is kind of complex though) and
then sync it up with the database.

Thanks for the help!

I'd say the Insert Into statements are a worthy choice.
You might choose to batch them together to reduce network traffic and speed
up the performance.

Thanks Steve,
After reading a bit, I realized that the best strategy was to take the
table(s) from the database and load them into a dataset (but to keep the
dataset small, I used SELECT * FROM MyTable WHERE 1=2 so as to have no
records). I then set the command builder to an insertcommand. Then all I
had to do was load my tables in the dataset with the info, then when all was
ready I could make one update to the dataset. Pretty neat for .NET! (as
opposed to the old recordsets in ADO).

Just a side technical note, as you have already solved the problem
correctly. The only way to do multiple record inserts is to insert each
record individually. When you use a DataSet to do multiple inserts, it does
them individually, but automatically. That makes it, as you've noticed, an
excellent tool for the job.

I have nothing against this dataset method. It certainly does make things
simple.
But in many cases you can get better performance by batching multiple insert
statements together into one long command string. That way only one
statement is sent across your network as opposed to N number of individual
statements.
I guess it depends on your priorities. Simplicity vs. Performance.
Of course both methods get significantly more complex when multiple user
concurrency issues are involved.
