雲數據庫SQL Server實例不支持修改參數，M爸雪ySQL實例支持修改參數，具體參數相媽列表見下文MySQL參數列表。

修改參數

1.登錄控制台->雲數據庫->管理雲數據庫實例。

2. 找到(dào)需要設置參數的目标實例，單擊管理

3. 在雲數據庫詳情頁面(miàn)最右側點擊參數設置

4. 修改參數後(hòu)，點擊地南預覽，預覽修改的參數

5. 點擊保存，保存參數修改

導入參數

1. 在參數設置頁面(miàn)，更多操作->導入參數吧在

2. 在導入參數彈出窗口，單擊确定導章了入參數

• 多參數導入, 請以換行形式進(jìn)行
• 導入參數值為字符時(shí)參數名與參數值那妹之間不能(néng)有空格，如binlog_checksum=CRC32
• 支持導入的參數見下文MySQL參數列表
