Thanks for the input doug...but do you think I posted the question without checking/searching this in msdn.microsoft?? 🙂

So if you've checked MSDN, seen the syntax description and looked at the examples at the bottom of the page, what specifically are you stuck with?

What have you got so far (from the documentation) and what isn't it doing that it should be?

your target table needs to have the same number of columns, ideally, for this simple example

CREATE TABLE BULKACT(SomeColumns VARCHAR (30),MoreColumns varchar(30))

BULK INSERT BULKACT FROM 'c:\Export_o.txt'

WITH (

DATAFILETYPE = 'char',

FIELDTERMINATOR = ',',

ROWTERMINATOR = '\n',

FIRSTROW = 1

)

Gail/Doug: As I mentioned, am pretty new to sql scripting....and am not sure what FROM 'data_file' in the statement listed. I don't have a file...I need to import rows from one table to another table on the same server.

That's not what BULK INSERT does.

Bulk insert, specifically and only, loads data from a file (text file usually, or comma-separated value) in the file system into a database table. It's for times when someone sends you a file and tells you to load that data into the database.

If you're copying data from one table to another, you don't want bulk insert.

A simple INSERT INTO ... SELECT ... FROM will do the job.

Have a stab at it (with reference to the docs as needed) and post if you get stuck with exactly what you're stuck with.

Ok Thank you. Thing is, I need to use BULK INSERT for some performance tests...so, am thinking I can create a file (text or csv) with all the records of Table 1 and save it on server and then use Bulk insert to import the data from that file into Table 2...hope I got it right.

Gail Shaw SSC Guru Points: 1004504 More actions · Answer 9

Why?

If you're copying data from one table to another on the same server, you would use INSERT ... SELECT, not bulk insert. Bulk insert is for when you're starting with a file, it's the wrong tool for when you're copying data from one table to another.

Quick thought, use SSIS, you'll have an option for bulk inserting there.

Well, if what you want to test is the performance of a BULK INSERT from a file, then yes, this is what you need to do. 😀

As was previously noted, your Table 2 must be defined with the same number of columns represented in your file and the data types of those columns must be appropriate for the data in the file for a simple BULK INSERT to work. Otherwise, you'll need a format file - see BOL for guidance.

bcp will probably be the way to go to get your 200 million rows into a flat file.

Thank you all for the inputs...I was able to perform the test using BULK Insert
