Oracle function to PostgreSQL

Question

I'm try to convert my Oracle function which contains SUBSTR() to PostgreSQL. Is there an equivalent function in PSQL? Thanks.

I manage to find a Oracle Instr() conversion to PostgreSQL.

Answer 1

You can use a code from Postgres documentation mentioned by michel-sim. Other possibility is Orafce extension - https://github.com/orafce/orafce or http://postgres.cz/wiki/Oracle_functionality_%28en%29 that is available for RedHat or Debian as binary package too.

Answer 2

There's substring, but you'd have to modify the invocations -- instead of substr(x, i, j) you need substring(x from i to j)
