Hi there,
I have dozens of tables where I need to rename one column in each of these. Is there any generic way to do that?
I am not really familiar with the scripting possibilities of Postgres.
Thanks a lot for your help!
Stefan
You can do with script. I made one on fly for this, other's might have more polished version.
-bash-4.1$ more rename.sh
#!/bin/bash
OLDCOLUMN=aa
NEWCOLUMN=a
for i in $(psql -t -c "select table_schema||'.'||table_name from information_schema.tables where table_schema='public';")
do
/opt/PostgreSQL/9.3/bin/psql -p 5432 -U postgres -c "alter table $i rename column $OLDCOLUMN to $NEWCOLUMN;"
done
Replace the port,user,OLDCOLUMN, NEWCOLUMN and SCHEMA according to your requirement.
