注意sql update的语法啊 Truncated incorrect DOUBLE value

注意 sql update的语法啊 已经被这个问题纠结过N次了， 每次都搞得头晕眼花

update sex_person set sex = '男' and keywords = '刚' where name like '%刚'  AND LENGTH(NAME) < 10;  // error

 不能用and啊

update sex_person set sex = '男' ,  keywords = '刚' where name like '%刚'  AND LENGTH(NAME) < 10; 

Truncated incorrect DOUBLE value: '男'
