Hash Match (Inner Join) cost 50% in my query - sql-server

Question

I have never interacted with Hash Join yet.
According to picture below, do I need an index on table tblFin_Invoices?
Or which table do I need to create index in order to avoid this Hash Join?
Is any chance I can do something to alleviate the query?

Answer 1

All the tables you use in the first query for #ValidInvoicesTable are also in the second query. Instead of using #ValidInvoicesTable, use the WHERE conditions from that SELECT and replace the WHERE condition in the second SELECT statement.
I'd also use BETWEEN instead of two statements for the date comparison, to get the same result you'll need to CAST/CONVERT the EffectiveDate, if the DateTime field actually contains Time.
I'd also make a join out of tblFin_InvoiceDetails.
I assume that you are going to use the #TempData table for something other the just a SELECT statement. If I'm wrong, you should remove the DECLARE and INSERT INTO regarding #TempData table completely.
Below is my suggestion.
declare
#EffDateFrom datetime = '2017-02-01',
#EffDateTo datetime= '2017-12-31'
DECLARE #TempData TABLE(
[QuoteID] int,
[QuoteGUID] [uniqueidentifier] NOT NULL,
[CompanyLocationGuid] [uniqueidentifier] NULL,
[UnderwriterUserGuid] [uniqueidentifier] NULL,
[InsuredGuid] [uniqueidentifier] NULL,

[ProducerContactGuid] [uniqueidentifier] NULL,
[EffectiveDate] datetime NULL,
--[InvoiceDate] datetime NULL,
[AccountingDate] datetime NULL,

[TransactionTypeID] varchar(2) NULL,
[QuoteStatusID] tinyint NOT NULL,
[PolicyNumber] [varchar](150) NULL,
[StateID] [char](2) NULL,
[Premium] [money] NULL,
BondRate decimal (5,4) NULL,
[PenalLiability] [money] NULL,
[CompanyCommission] decimal(3,2) NULL
