通过GROUP_CONCAT加入表行,失败了!它不工作？

Question

我不知道为什么它不起作用.

"SELECT id GROUP_CONCAT(skill SEPARATOR ', ') FROM resume_skills GROUP BY id";

我有一个表resume_skills,然后有两个字段id和技能.它返回一个像这样的错误:

ERROR: 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 'GROUP_CONCAT(skill SEPARATOR ', ') FROM resume_skills GROUP BY id' at line 1

我还没搞清楚.救命？

Answer 1

你错过了id和group之间的逗号(,).

正确的查询:

SELECT id, GROUP_CONCAT(skill SEPARATOR ', ') FROM resume_skills GROUP BY id
