Question

我有2张桌子，即。 Regtbl和Invoicetbl

Regtbl具有regid，createddatetime，isActive（bool），invoicetbl具有regid，invMonth，invYear，invUploadedDateTime。

我想创建一个查询，该查询将向我返回在给定日期范围内未提交发票的所有regid。

假设我想获得那些在一月至五月之间未提交发票的用户的记录。

下面是我尝试过的查询，但似乎无法正常工作。

Declare @MinYear int, @MaxYear int, @Minmonth smallint , @Maxmonth smallint
                        Set @MinYear = '2019'
                        Set @MaxYear = '2019'
                        Set @Minmonth = '01'
                        Set @Maxmonth = '05'
                        CREATE TABLE #TempTable(
                        PrimaryEnterpriseId nvarchar(50),
                        RegistrationNm nvarchar(50),
                        InvoiceMonth char(3),
                        InvoiceYear char(4))
                        While (@MinYear <= @MaxYear)
                        BEGIN
                            While (@Minmonth <= @Maxmonth)
                            BEGIN
                                    INSERT INTO #TempTable Select distinct t1.primaryenterpriseid, t1.RegistrationNm, @Minmonth as InvoiceMonth, @MinYear as InvoiceYear
                                    from regtbl t1
                                    where  NOT EXISTS(
                                    SELECT t2.enterpriseid, t2.InvoiceMonth,t2.InvoiceYear,t2.RegistrationID
                                    FROM invoicetbl t2
                                    WHERE t1.registrationid=t2.registrationid and t2.InvoiceMonth = @Minmonth and t2.ApprovalStatus!='Rejected'  ) 
                                                                            and t1.DeregisteredInd=0 and t1.RegistrationType='Register'  and t1.StatusInd=1 
                                    Set @Minmonth = @Minmonth + 1
                            END
                            SET @MinYear = @MinYear + 1
                        END
                        select * from #TempTable
                        DROP TABLE #TempTable

Answer 1

Select distinct t1.primaryenterpriseid, t1.RegistrationNm
From regtbl t1
Left Outer Join invoicetbl t2 
On t1.registrationid=t2.registration
Where t2.InvoiceMonth = @Minmonth 
And t2.ApprovalStatus!='Rejected'
And t1.DeregisteredInd=0 
And t1.RegistrationType='Register'  
And t1.StatusInd=1
And t2.registration is null
