Psycopg2 using wildcard causes TypeError

Question

Currently I am attempting to search a database to grab certain events. My query is as such

SELECT * FROM events WHERE summary ILIKE E\'%test%\' AND start_tim         


        

Answer 1

my guess is something about your "%"'s is confusing python. in psycopg2 i do my wildcard "like" queries like this:

#!/usr/bin/python

import sys,os.path,psycopg2
db=psycopg2.connect("dbname=music")

for line in sys.argv[1::]:
    cursor=db.cursor()
    key="%"+line+"%"
    cursor.execute("select count(*) from pool where path like %s",(key,))
    if cursor.fetchone()[0] != 1:
        sys.stderr.write("ambiguous stem or no such song")
        sys.exit(-1)
    cursor.execute("insert into spool select path from pool where path like %s",(key,))
    cursor.close()
    db.commit()
db.close()

with user-supplied search strings like in this script you would probably want to escape out any "%"'s in them, which i suspect would otherwise be legit wildcards in the query, but i haven't gotten that far yet
