Question

这是我的存储过程，我与水晶报告连接，我想返回开始日期和结束日期，这是我从参数，如果日期为空，然后没有显示报告，但如果日期有一些值，那么价值印刷品。

CREATE PROCEDURE [dbo].PatientClaimInfo

@StartDate Date = NULL,
@EndDate Date = NULL

AS
BEGIN
select p.VLNAME + ' ' + p.VFNAME AS Patients_Name, p.IPATID AS Patient_ID, p.DDOB AS dob,
       d.NCOPAY, d.NVTOTPLAN, d.NVWOPLAN, d.NVWOPAT, d.NVADJPLAN, d.NVADJPAT, d.NVPAIDPLAN,
       d.NVPAIDPAT, d.NVBALPLAN, d.NVBALPAT, d.NAPPTBAL, d.VPAYSTAT AS Status
From   pmvixtr d

INNER JOIN  pmptxft p ON p.IPATID = d.IPATID


Where @StartDate <= d.DSDATE AND @EndDate >= d.DSDATE

END

Answer 1

尝试

CREATE PROCEDURE [dbo].PatientClaimInfo

@StartDate Date = NULL,
@EndDate Date = NULL

AS
BEGIN
IF (@StartDate Date IS NOT NULL AND @EndDate Date IS NOT NULL)
THEN

select p.VLNAME + ' ' + p.VFNAME AS Patients_Name, p.IPATID AS Patient_ID, p.DDOB AS dob,
       d.NCOPAY, d.NVTOTPLAN, d.NVWOPLAN, d.NVWOPAT, d.NVADJPLAN, d.NVADJPAT, d.NVPAIDPLAN,
       d.NVPAIDPAT, d.NVBALPLAN, d.NVBALPAT, d.NAPPTBAL, d.VPAYSTAT AS Status
From   pmvixtr d

INNER JOIN  pmptxft p ON p.IPATID = d.IPATID


Where @StartDate <= d.DSDATE AND @EndDate >= d.DSDATE


END
END

Answer 2

在您的select语句中，您可以包含@StartDate，@ EndDate

e.g。

select @StartDate, @EndDate, .... <rest of your select statement>...

我还建议在你的where子句中使用where d.DSDATE BETWEEN（@StartDate，@ EndDate）

如果你不想在@StartDate和@EndDate为NULL时选择任何东西，那么在WHERE Clause中使用它可能非常昂贵...我建议有一个if条件

IF @StartDate IS NOT NULL AND @EndDate IS NOT NULL
select.....

END IF

我在“存储过程”中作为参数获得的返回日期
