多用户的批准和拒绝

Question

We Have a table of approval like below:

In above table we have ApprovalId and ApprovalLevel like first level approval and second level approval in ApprovalLevel (For Approving Approval by its level). I am trying to fetch record in query if specific user ApprovalLevel >= 1 then check its previous ApprovalStatus if it Approved then show its record too.

I have tried many things but still not getting specify record.

In Simple term select record with User if only if its ApprovalLevel=1 or its previous ApprovalLevel ApprovalStatus=1.

Please help me on this: [IN this table ApprovalStatus: 0 = Pending and 1:Approved]

I believe this is what you are requesting:

SELECT
    ApprovalStatus,
    ApprovalLevel,
    CreatedOn
FROM
    approval
WHERE
    ApprovalLevel = 1
    OR (ApprovalLevel > 1 AND ApprovalStatus = 1)
;
