Unable to Pass in Table Name for Query psycopg2-CodePudding

I am trying to pass in the table name for my queries but it doesn't work when I use the code below.

def retrieve_data_single(table_name, date):
    
    
    conn = psycopg2.connect(host="localhost", port = 5432, database="db", user="user")
    cur = conn.cursor()

    date = date   "%"
    
    cur.execute("""SELECT open, date FROM table_name WHERE date LIKE (%s)""" , [date])

retrieve_data_single(table_1, '2022-12-12'):

CodePudding user response：

According to:

Passing table name as a parameter in psycopg2

You should be using this

template:

from psycopg2 import sql
cur.execute(
    sql.SQL("insert into {table} values (%s, %s)")
        .format(table=sql.Identifier('my_table')), # table name here
    [10, 20]) ## other parameters here
