如何从 MYSQL 中的 table 中删除冻结值

Question

嗨，我有一个 TABLE 喜欢

DATE       VALUE            NAME
23MAY       156            CONSUMPTION_1
24MAY       122            CONSUMPTION_1
25MAY       122            COMSUMPTION_1
26MAY       122            CONSUMPTION_1
11APR       177            CONSUMPTION_2
12APR       199            CONSUMPTION_2
13APR       199            CONSUMPTION_2
14APR       199            CONSUMPTION_2
19SEP       318            CONSUMPTION_3
20SEP       282            CONSUMPTION_3
21SEP       183            CONSUMPTION_3

现在如何删除所有行的冻结值 即

DATE       VALUE            NAME
23MAY       156            CONSUMPTION_1
11APR       177            CONSUMPTION_2
19SEP       318            CONSUMPTION_3
20SEP       282            CONSUMPTION_3
21SEP       183            CONSUMPTION_3

提前致谢

试试这个：

DELETE FROM MyTable 
GROUP BY value 
HAVING COUNT(*) > 1;
