當MySQL將varchar 使用cast轉換成float的時候報錯處理

使用MySQL將varchar轉換成float是報錯
執行語句：

SELECT CAST(2000 AS FLOAT) as result

錯誤信息：

1064 - 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 'FLOAT) as result' at line 1

處理方式：

SELECT cast('2022' as DECIMAL(10,2)) as result

成功執行且保留兩位小數
