Question

我需要建议写一个满足这些条件的查询。

我将三个参数传递给存储过程：

to date
from date
is active

要求是这样的：

页面加载显示谁是今天的regisatar
仅传递to date然后我只需要显示那些注册到日期的人
传递from date时仅显示那个日期之后的人
并且只有那些落在他们之间的人

我尝试了但这完全是浪费。

If (@viewPending = 1 or @viewPending = 0 )
    Begin
        IF @TDate IS NULL AND @FDate IS NOT NULL
            SELECT 
            RegDate,
            CenterName  As [Center Name],
            OwnerName   As [Owner Name],
            MobileNo    As [Mobile],
            MailID      As [EMail ID],
            isVerified  As [Verified]
        FROM  TBL_iREGFORM
        WHERE REGDATE >= @FDate AND isVerified in (Case When  @viewPending =1 Then 0 Else 1 | 0 End) 
      IF @TDate IS NOT NULL AND @FDate IS  NULL
            SELECT 
            RegDate,
            CenterName  As [Center Name],
            OwnerName   As [Owner Name],
            MobileNo    As [Mobile],
            MailID      As [EMail ID],
            isVerified  As [Verified]
        FROM  TBL_iREGFORM
        WHERE REGDATE <= @FDate AND isVerified in (Case When  @viewPending =1 Then 0 Else 1 | 0 End)
       IF @TDate IS NOT NULL AND @FDate IS NOT NULL
            SELECT 
            RegDate,
            CenterName  As [Center Name],
            OwnerName   As [Owner Name],
            MobileNo    As [Mobile],
            MailID      As [EMail ID],
            isVerified  As [Verified]
        FROM  TBL_iREGFORM
        WHERE REGDATE BETWEEN  @FDate AND @TDATE AND isVerified in (Case When  @viewPending =1 Then 0 Else 1 | 0 End)
    ELSE

            SELECT 
            RegDate,
            CenterName  As [Center Name],
            OwnerName   As [Owner Name],
            MobileNo    As [Mobile],
            MailID      As [EMail ID],
            isVerified  As [Verified]
        FROM  TBL_iREGFORM
        WHERE REGDATE =CONVERT(VARCHAR(10),GETDATE(),103) AND isVerified in (Case When  @viewPending =1 Then 0 Else 1 | 0 End)
