Because you're only getting the first row of the query result, even though the cursor that contains the result (should be server side in this case) does have more rows.

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....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()
There's your problem. You'll want to either use fetchall() if you want to get all the rows, see http://initd.org/psycopg/docs/cursor.html#cursor.fetchone
conn.close()
return rows
