Question

我无法在sql中插入一些文本，我想知道如何处理该字符串，以便它被接受。

无法编辑json文件，因为文件太大。

这是我得到的错误：

Traceback (most recent call last):
  File "test.py", line 31, in <module>
    main()
  File "test.py", line 28, in main

    json_data = json.load(open(json_path, 'r'))

    cursor.execute("""create table test_table (id integer AUTO_INCREMENT,PRIMARY KEY (id),
                                               text text);""")
    db_connection.commit()
    text = get_value_from_key(json_data, "text")
    cursor.execute("""insert into test_table (text) values (%s)""", (text,))

if __name__ == "__main__":
    main()

test.json

{
    "text": "+1: Create a 1/1 black Vampire creature token with lifelink.\n−2: You get an emblem with \"Creatures you control get +1/+0.\"\n−6: Destroy up to three target creatures and/or other planeswalkers. Return each card put into a graveyard this way to the battlefield under your control."
}

Answer 1

就是这个

cursor.execute("CREATE DATABASE " + db_name + " DEFAULT CHARACTER SET utf8")

SQL插入中的DataError
