是的，我們可以做到。讓我們首先創建一個表-mysql>?create?table?DemoTable

(

ID?int,

GameScore?int

);

使用插入命令在表中插入一些記錄-mysql>?insert?into?DemoTable?values(15,848747);

mysql>?insert?into?DemoTable?values(13,909049);

mysql>?insert?into?DemoTable?values(34,98474646);

mysql>?insert?into?DemoTable?values(31,948474);

使用select語句顯示表中的所有記錄-mysql>?select?*from?DemoTable;

輸出結果+------+-----------+

|?ID???|?GameScore?|

+------+-----------+

|?15???|?848747????|

|?13???|?909049????|

|?34???|?98474646??|

|?31???|?948474????|

+------+-----------+

4?rows?in?set?(0.00?sec)

以下是在單個查詢中更新具有最高ID的行的查詢-mysql>?update?DemoTable?set?GameScore=GameScore+10?ORDER?BY?ID?DESC?LIMIT?1;

Rows?matched?:?1?Changed?:?1?Warnings?:?0

讓我們再次檢查表記錄-mysql>?select?*from?DemoTable;

輸出結果+------+-----------+

|?ID???|?GameScore?|

+------+-----------+

|?15???|?848747????|

|?13???|?909049????|

|?34???|?98474656??|

|?31???|?948474????|

+------+-----------+
