sql server未关闭的引号,因为插入了带有的字符串

这是我的密码:

for i in dat.columns:
    sql_query = """\
                EXEC sys.sp_addextendedproperty
                     @name = N'Description',
                     @value = N'{}',
                     @level0type = N'Schema', @level0name = '{}',
                     @level1type = N'Table',  @level1name = '{}',
                     @level2type = N'Column', @level2name = '{}'
                """.format(dat[i][0], db, tb, i)

pyodbc.ProgrammingError: ('42000', "[42000] [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Incorrect syntax near 's'. (102) (SQLExecDirectW); [42000] [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Unclosed quotation mark after the character string '\n                    '. (105)")

如何处理这个问题?

谢谢您!
