如何使用 Python 从 CSV 文件在 MySQL 中创建列名？

Question

I usually work with large CSV data sets. Opening these files take a hell lot of time. My plan is to directly load the csv files without accessing them but am getting an error while creating the table to load the data.

import string
import csv
import mysql.connector
mydb=mysql.connector.connect(host="localhost",user="root",password="password")
mycursor = mydb.cursor()
with open(r"C:\Users\rcsid\Documents\Office Programs\Working prog\MOCK_DATA.csv") as csvfile:
    csv_reader = csv.DictReader(csvfile)
    line_count = 0
    for row in csv_reader:
        if line_count == 0:
            print(f'create table rd.data ( {" varchar(50), ".join(row)} varchar(50))')
            mycursor.execute(f'create table rd.data ( {" varchar(50), ".join(row)}) varchar(50))')
            line_count += 1
        line_count += 1

The print statement is giving the following results:

create table rd.data ( id varchar(50), first_name varchar(50), last_name varchar(50), email varchar(50), boole varchar(50), coin varchar(50))

The above statement seems correct But the execute statement is throwing an error:

ProgrammingError: 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') varchar(50))' at line 1

This is the starting part. The full program will have many other checks. Wanted to know how to solve this error? PS: New to Python

Answer 1

I was able to resolve this by creating a string statement:

sql_str=f'create table rd.data ( {" varchar(50), ".join(row)} varchar(50))'
mycursor.execute(sql_str)

This resolved the issue.
