如何在 T-SQL 中为新参数设置特定条件

Question

我有一个现有代码，我必须向其中添加新参数 - @Depreciation“是”或“否”

如果@Depreciation = 1（我认为这对应于“是”） 那么我希望现有代码的特定条件是 FALSE（我用 '-- ***' 标记了该代码部分），

反之亦然 -

如果@Depreciation = 0（'否'） 那么我希望代码中的条件是 是的

条件是

 (NOT (acct.[GLAccountCode] IN (N'9040',N'9047',N'4130')))

位于下面代码中的第一个 WHERE 之后。

请不要过多关注整个代码。 我必须修改的唯一部分是 - 'DECLARE @Depreciation....' 和 在第一个 'WHERE .....' 之后 - 我标记了 -- ***

     DECLARE @FYMonthBOP date = '07-01-2016'
     DECLARE @FYMonthEOP date = '07-01-2018'
     DECLARE @GLProgramGroupsWHID int = -1
     DECLARE @GLProgramsWHID_Groups int = -1
     DECLARE @GLProgramGroupSetsWHID int = -1

     DECLARE @Depreciation bit = 1 -- *** This is my added Parameter

Answer 1

像这样：

(
  (
    @Depreciation = 0 /* FALSE AND EXISTING CONDITION */
    and NOT (acct.[GLAccountCode] IN (N'9040',N'9047',N'4130'))
  )
  or
  (
    @Depreciation = 1 /* OR TRUE AND NOT EXISTING CONDITION */
    and (acct.[GLAccountCode] IN (N'9040',N'9047',N'4130'))
  )
)
