我有这些 pymmsql 索引错误我在我的代码中创建了 3 个索引，我想删除它们但它们不会删除我收到这些错误代码：

DbConnect = 'Micros'
myDbConn = pymssql.connect(*******,"******", "*******",DbConnect)
cursor = myDbConn.cursor()
cursor.execute("""DROP INDEX [IF EXISTS]
                Micros ON payrolldata;""")
cursor.execute("""DROP INDEX [IF EXISTS]
               MainSort ON s20data,StoreSort ON s20data;""")
myDbConn.commit()

错误：

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "C:\Python37-32\lib\tkinter\__init__.py", line 1705, in __call__
return self.func(*args)

正确的语法应该是。

DROP INDEX IF EXISTS IndexName;
DROP INDEX IndexName;

方括号表示参数或语句的一部分是可选的。请参阅文档
