我希望UPDATE列TOF_2的条件可以描述如下：如果同一group_id的任何行显示TRUE，则此行的所有行group_id TRUE FALSE group_id TOF_2 UPDATE table
SET TOF_2 = CASE
WHEN TOF is true THEN TOF_2 = true ELSE TOF_2 = FALSE
GROUP BY group_id
psexec.exe \\$computer -s -u Adminuser -p AdminPassword msiexec /i C:\Avamar\AvamarClient-windows-x86_64-7.0.102-47.msi /qb ADVANCED_OPTIONS=1 CHANNEL=100
{{1}} {{1}}。{/ 1}}
我认为IF或CASE可以解决问题，但我不确定正确的表达方式？
{{1}}
我知道这是错的，但可能是朝着正确的方向发展？以某种方式描述任务并不容易。

您可以使用EXISTS来检查：
UPDATE a SET tof_2=true WHERE
EXISTS (SELECT 1 FROM a a1 WHERE a1.group_id=a.group_id AND tof=true);
