I have created a function to search a Postgresql database but it only pulls up the first row of the database no matter what value I search for. Why would it only pull up the first row of the database? I am using Psycopg2 2.6 and Python 3.5.
All my other functions to update, add, delete, view all rows are working fine. I am able to run queries on the database and only pull up the rows I need using psql command line no problem.
Here is my function.
from tkinter import *
import psycopg2
import psycopg2
def search(title=None, isbn=None, year=0):
'''Search the database rows'''
conn = psycopg2.connect("dbname='books'")
cur = conn.cursor()
cur.execute("SELECT books.title, books.isbn, books.year FROM books WHERE books.title = title OR books.isbn = books.isbn OR books.year = year")
rows = cur.fetchone()
conn.close()
return rows
'''Search the database rows'''
conn = psycopg2.connect("dbname='books'")
cur = conn.cursor()
cur.execute("SELECT books.title, books.isbn, books.year FROM books WHERE books.title = title OR books.isbn = books.isbn OR books.year = year")
rows = cur.fetchone()
conn.close()
return rows
