Обсуждение: Multiple COPYs

Hello,

Having a great time with PG - ported an erp from oracle and db2. First
I tried MySql but choked somewhere in the 900 table region. I have a
python script to translate the syntax and it loads about 2000 tables.

Now I want to COPY my dumps - I have 1 data dump for each table. Any
tips on what to use so that I can read the file name into a variable
and pass it as the file name in the COPY command and have one script
load all my tables?

Thanks for any help.

Why not use Python or a simple shell script to generate a file like:

\copy table1 from 'table1.txt'
\copy table2 from 'table2.txt'
....

And then do psql -f filename

Should be pretty easy from the shell, something like (untested):

for f in *.sql; do
  tablename=`basename $f .sql`
  psql -c "\\copy $tablename from $f" mydatabase
done
