palpg 2.3

Postgres Wrapper Class using psycopg2

Wrapper Class around Psycopg2 for PostgreSQL

In psycopg2 after connecting to the database, for every read execute statement the data needs to be fetched and for evey write execute statement the data needs to be committed. But this class eliminates these requirements and make it simple to read and write to the database.

Files:

palpg/__init__.py

Installation:

sudo pip3 install palpg

Usage Examples:

import palpg

db = palpg.db(“host=HOST port=PORT dbname=DBNAME user=USER password=PASSWORD”) ##-connect to the database

db.read(“sql statement”) ##-returns the read data from database with flat=True

db.read(“select item from table”, flat=False) ##-returns the raw read data

db.read(“select item from table where item = %s”, (sub1,)) ##-read with string substitution

db.read1(“sql statement”) ##-returns the first read data similar to fetchone

db.write(“sql statement”) ##-writes the data and commits to the database

db.clear() #-to reconnect if any transaction error

For other psycopg connection commands use the connection class

db.conn….
