为什么我在 SSMS 中不断收到 Incorrect usage of const UDF？

Question

我不断在 SSMS（使用 v17.7）和 RedGate SQL 中收到警告提示：

Incorrect usage of const UDF

下划线SYSUTCDATETIME()

以下两处加下划线SYSUTCDATETIME()

   SELECT 2
     FROM (VALUES (CAST('2020-06-26' AS DATETIME2(7)))) AS s (SampleAt)
    WHERE s.SampleAt BETWEEN SYSUTCDATETIME() AND DATEADD(DAY, 100, SYSUTCDATETIME())

以下完全没有下划线:

    SELECT 2
     WHERE CAST('2020-06-26' AS DATETIME2(7)) BETWEEN SYSUTCDATETIME() AND DATEADD(DAY, 100, SYSUTCDATETIME())

也完全不加下划线:

DECLARE @now AS DATETIME2 = SYSUTCDATETIME()

   SELECT 2
     FROM (VALUES (CAST('2020-06-26' AS DATETIME2(7)))) AS s (SampleAt)
    WHERE s.SampleAt BETWEEN @now AND DATEADD(DAY, 100, @now)

我与开发人员进行了交谈。这是工具中的错误。感谢您识别它。他们正在积极努力进行修复，应该很快就会发布。
