计数不同时出现错误 1064

Question

我的查询语句

SELECT Count(DISTINCT name) 
FROM facebook.users

结果

mysql.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 '\xef\xbb\xbfSELECT Count(DISTINCT name) \r\nFROM facebook.users' at line 1")

我该如何解决这个问题，谢谢

Answer 1

您应该检查您是如何传递查询的。 \xef\xbb\xbf 是 UTF-8 BOM.

The UTF-8 representation of the BOM is the (hexadecimal) byte sequence 0xEF,0xBB,0xBF

SELECT Count(DISTINCT name) FROM facebook.users
-- query is correct

计数不同时出现错误 1064

Error 1064 when COUNTING DISTINCT
