Question

我正在尝试将所有数据插入到我创建的表中。这是我的代码的相关部分：

    rows_inserted = 0 
    table_name = "mytable"

    for row in ordered: # ordered is a list of lists. it contains all my data
        sql = ("INSERT IGNORE INTO %s (ID, A, B, C, D, E, F) VALUES (%s, %s, %s, %s, %s, %s, %s)")

        rows_inserted += cursor.execute(sql, (table_name, 1, row[0], row[1], row[2], row[3], row[4], row[5]))

    print(rows_inserted) # to verify that all the records have been inserted to the table

当我在服务器上运行脚本时，出现以下错误：

ProgrammingError: (1064, "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 ''mytable' (ID, A, B, C, D, E, F) VALUES (1, "QP123", ....

我也尝试用反引号包装列名，但它没有帮助。

表名不能参数化。您必须使用字符串格式添加它。

sql = """INSERT IGNORE INTO {t} (ID, A, B, C, D, E, F) 
         VALUES (%s, %s, %s, %s, %s, %s, %s)""".format(t=table_name)
rows_inserted += cursor.execute(sql, (1, row[0], row[1], row[2], row[3], row[4], row[5]))

我不确定这是哪里记录的，但你可以通过尝试来看到这一点：

cursor = connection.cursor()
sql = 'CREATE TABLE %s'
cursor.execute(sql, ['test'])

Python中MySQL语句中的语法错误（1064）
