Sql 根据输入删除where子句的一部分

在下面的查询中，如果@searchBy的输入为1，我想省略由@searchBy=@searchBy创建的过滤器。我该怎么做

CREATE PROC [dbo].[RptCashCollectionInner]
    @branchId int, 
    @searchBy int, 
    @paidDate datetime 
AS
BEGIN
    SELECT Id
    FROM reading
    WHERE created_by = @searchBy 
      AND branch_id = @branchId
END;

---

您可以使用or运算符短接“按元素搜索”：

CREATE PROC [dbo].[RptCashCollectionInner]
  @branchId int, @searchBy int, @paidDate datetime AS
BEGIN
  select Id, from reading
  where (@searchBy = 1 or created_by=@searchBy) and branch_id=@branchId
END;

CREATE PROC [dbo].[RptCashCollectionInner]
  @branchId int, @searchBy int, @paidDate datetime AS
BEGIN
  select Id, from reading
  where @searchBy in (1, created_by) and branch_id=@branchId
END;

或者更优雅地使用in运算符：

CREATE PROC [dbo].[RptCashCollectionInner]
  @branchId int, @searchBy int, @paidDate datetime AS
BEGIN
  select Id, from reading
  where (@searchBy = 1 or created_by=@searchBy) and branch_id=@branchId
END;

CREATE PROC [dbo].[RptCashCollectionInner]
  @branchId int, @searchBy int, @paidDate datetime AS
BEGIN
  select Id, from reading
  where @searchBy in (1, created_by) and branch_id=@branchId
END;

我真的很喜欢带IN运算符的那个。我真的很喜欢带IN运算符的那个。
