Error: '1064 (42000): You have an error in your SQL syntax

Question

我在 Python 中使用 MYSQL 编写代码来创建数据库配方。我写了一些变量来创建不同的表。可以创建所有，但导致错误的除外：

create_recipe_ingredient_table = """
CREATE TABLE IF NOT EXISTS recipe_ingredient (
    recipe_ingredient_id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
    amount INT,
    recipe_id INT,
    ingredient_id INT,
    measure_id INT,
    FOREIGN KEY (recipe_id) REFERENCES recipe(recipe_id),
    FOREIGN KEY (ingredient_id) REFERENCES ingredient(ingredient_id),
    FOREIGN KEY (measure_id) REFERENCES measure(measure_id)
    """

我收到此错误消息：Error: '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 '' at line 9'

顺便说一下，我不知道为什么说“第 9 行”，因为这个变量从我程序的第 132 行开始。

我还假设这个变量导致了这个错误，因为当我删除它时，错误消失了，但我可能错了。

感谢您的宝贵时间:)

我想您错过了语句末尾的 )。尝试：

create_recipe_ingredient_table = """
CREATE TABLE IF NOT EXISTS recipe_ingredient (
    recipe_ingredient_id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
    amount INT,
    recipe_id INT,
    ingredient_id INT,
    measure_id INT,
    FOREIGN KEY (recipe_id) REFERENCES recipe(recipe_id),
    FOREIGN KEY (ingredient_id) REFERENCES ingredient(ingredient_id),
    FOREIGN KEY (measure_id) REFERENCES measure(measure_id));
    """
