解決方案1：github

name和group在MYSQL中是關鍵字，字段名更名便可。web

解決方案2：spring

`（鍵盤數字1左側鍵）是 MySQL 的轉義符，避免和 mysql 的自己的關鍵字衝突，只要你不在列名、表名中使用 mysql 的保留字或中文，就不須要轉義。sql

全部的數據庫都有相似的設置，不過mysql用的是`而已。一般用來講明其中的內容是數據庫名、表名、字段名，不是關鍵字。例如：數據庫

select from from table;
第一個from是字段名，最後的table表名，可是同時也是mysql關鍵字，這樣執行的時候就會報錯，因此應該使用
select `from` from `table`;
固然，爲了便於閱讀，不建議使用關鍵字做爲字段名、表名，同時，應該對數據庫名、表名、字段名用一對兒反引號包含。apache
