| Hi Pavel, Thanks. The situation is, I have the DB class which will return the connection object that is created using the PDO class. And am using that object to perform the db operations. ie: $DB->prepare("") Further I have the data in a CSV file which has to be inserted into the table. Here is the command that I have used to import that data: $DB->exec("\COPY table1 FROM data.csv WITH DELIMITERS ','"); And this dosen't work, it throws an error "error near "\" char 1 along with the command But the same command works fine on the psql prompt. Thanks again, - Babu --- On Fri, 7/2/10, Pavel Stehule <pavel.stehule@gmail.com> wrote:

you cannot use \copy - this command is available only in psql. use just copy ...

As mentioned earlier just use copy, also look into using copy from
stdin and then just feeding the lines to pgsql through php instead of
having pgsql get it from a system file. This way the php script and
the db don't have to be on the same machine.
