Re: How to insert from linux to postgreSQL

Is the log file "ready" for INSERT, line by line? If not, you need to preprocess it. The 2 solutions I would use are psycopg for Python or sed + INSERT depending.

Use case:
I want to read a log file on my linux server and write each line out to a row in a postgreSQL table.

Presumably some manipulations need to be performed so that you can't just do COPY FROM STDIN?

When I do inserts however I want to make sure I am using prepared statements to avoid SQL injections. I know how to do this is Java but I have not found an example using a linux bash scripts.

Does anyone have an example they could point me to?

I think the problem is that you need an open connection to use prepared statements, and you can't do that in bash. What about using Python? (After all, that's a scripting language, too.)
