OperationalError：“：1”附近：SQLite中的语法错误

Question

I have this error.

My Table column names are as followed after i performed join and union:

['A','B','C','B:1','D','B:2','E']

In order to drop/rename the Table columns, I executed this query:

query = '''
        CREATE TABLE New_Table
        ['A','B_a','C','B_b','D','B_c','E']
        '''
query1 = '''
        INSERT INTO New_Table
        ('A','B_a','C','B_b','D','B_c','E')
        SELECT A, B, C, B:1, D, B:2, E
        FROM Table
        '''

import sqlite3
conn = sqlite3.connect('dbase_Sqlite')  # create or open db file
curs = conn.cursor()
curs.execute(query)
conn.commit()
curs.execute(query1)
conn.commit()

I got this error:

OperationalError: near ":1": syntax error

Apparently the ":1" and ":2" were added by the sqlite JOIN or UNION earlier. How should i deal with it?

Answer 1

I found an answer here, escaping the column names by giving "" to all column names in the query. It works.

query1 = '''
        INSERT INTO New_Table
            ('A','B_a','C','B_b','D','B_c','E')
        SELECT "A", "B", "C", "B:1", "D", "B:2", "E"
        FROM Table
        '''
