COUNTing函数输出返回的值不同于直接运行稍微修改的SQL

问题描述 投票：2回答：2

编辑：DB是SQL Server 2008R2

所以，基本上我遇到的问题是行数＃= count（*）。运行此代码：

SELECT *
FROM Fn_ForecastReport_TEST(NULL)

返回519行输出。但是，运行此代码：

SELECT COUNT(*)
FROM Fn_ForecastReport_TEST(NULL)

返回502.这非常令人费解，所以我拿了函数的代码：

CREATE FUNCTION dbo.Fn_ForecastReport_TEST(@Date DATE = NULL)
RETURNS @ForecastReportTable TABLE

SELECT count(*)
FROM FinalOutput;

本质上，唯一的变化是将@Date切换到DECLARE而不是SET，同时删除函数输出的INSERT。是否有一些带有函数的怪癖会导致计数返回一个不同于实际行数的值？

这是JetBrain的DataGrip产品的一个问题。当我在SSMS中运行相同的代码时，它返回了COUNT的适当数量。

SQL Server有时会在sys.sysindexes表/视图中提供不准确的信息...尝试更新索引和统计信息，看看它是否仍然不匹配。

如果它被清除，那么count（*）将其行数从索引而不是表中拉出，而select返回实际的行。

nvm，jetbrain做到了！多么糟糕!!
