即使提供或未提供最后一个字符，如何执行此sql查询

即使提供或未提供最后一个字符，它也应返回同一行

DECLARE @FolderNo VARCHAR(50) = 'T98/11567A'
select * from Cm.Folder WHERE FolderNo LIKE @FolderNo +'_'


DECLARE @FolderNo VARCHAR(50) = 'T98/11567'
select * from Cm.Folder WHERE FolderNo LIKE @FolderNo +'_'

---

如果多个尾随字符都可以

DECLARE @FolderNo VARCHAR(50) = 'T98/11567A'
select * from Cm.Folder WHERE FolderNo LIKE @FolderNo + '%'

或

如果零个或一个尾随字符可以

DECLARE @FolderNo VARCHAR(50) = 'T98/11567A'
select * from Cm.Folder WHERE FolderNo = @FolderNo OR FolderNo LIKE @FolderNo + '_'

DECLARE @FolderNo VARCHAR(50) = 'T98/11567A'
select * from Cm.Folder WHERE FolderNo = @FolderNo OR FolderNo LIKE @FolderNo + '_'
