Обсуждение: Using Batch Files to Create DB Structure

Greetings,

I'm coming over from MySQL.  I'm running SUSE Linux 9.2, running PGSQL 7.4.8.

In MySQL, I could use a simple batch file to run all my table creation
statements:
mysql -u user -p mydb < /file/path/batchfile.sql

Is this possible with PGSQL?  Can I do this, for instance:
psql -W mydb < /file/path/batchfile.sql

and get all my tables created?

Or is this why there are a dozen languages for server programming?  If
redirecting the input from a batchfile is possible, please point me to
the right documentation..  If not, I'll go back to the languages
section of the manual.  Many thanks in advance.

Don

Yes.

I always have to play with it to get the command line right.  And then
when loading a mysql dump into postgreSQL I have to play with it
some more.

What works best for me is to put drop table statements in at the begining
of the dump, then I keep loading it in over and over, each time
noting the errors and correcting the definitions until I get the table
defined and the data loaded.

The data types are slightly different mostly.

There is a script to go from mysql to postgreSQL somewhere, but I've never
used it.  Always did it by hand.

Yes, PostgreSQL has command line tool like mysql. The manual location
is:
