在 mysql 数据库上使用 python 插入表时 Sql 语法错误

Question

I'm trying to implement the code on this video to my mysql database. When I enter the values by hand to python code it works. However when i use python dictionaries for getting entries from gui like the video it's says: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ':b_name, :b_category, :b_status, :b_author)' at line 1 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ':b_name, :b_category, :b_status, :b_author)' at line 1

On video he uses SQLite this can be the problem but i'm not sure.

my code is here

# Insert Into Table
c.execute("INSERT INTO `books` (`bookName`, `bookCategory`, `BookCurrentStatus`, `bookAuthor`) VALUES (:b_name, :b_category, :b_status, :b_author)",
        {
            'b_name': b_name.get(),
            'b_category': b_category.get(),
            'b_status': b_status.get(),
            'b_author': b_author.get()
        })

Answer 1

I believe that you are not actually doing string replacement with your current setup, try this:

# Insert Into Table
c.execute("INSERT INTO `books` (`bookName`, `bookCategory`, `BookCurrentStatus`, `bookAuthor`) VALUES ({b_name}, {b_category}, {b_status}, {b_author})",
        {
            'b_name': b_name.get(),
            'b_category': b_category.get(),
            'b_status': b_status.get(),
            'b_author': b_author.get()
        })

MySQLdb only supports the format and pyformat parameter styles . The named parameter style used in the video isn't supported.
