Stored-procedure is very slow - stored-procedures

I have the following stored-procedure in SQL server.
My code is the following:
CREATE PROCEDURE [dbo].[current_call]
-- Add the parameters for the stored procedure here
#user_id nvarchar(128)
AS
BEGIN
SET FMTONLY OFF
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE #LocUserId nvarchar(128)
SET #LocUserId = #user_id
-- Insert statements for procedure here
SELECT dbo.Call.call_id, dbo.Call.amb_id as ambulanceNum, dbo.Call.patient_number as patientId, dbo.Call.patient_age, dbo.Call.patient_sex as gender, dbo.Call.patient_phone, dbo.Call.caller_name, dbo.Call.call_received, dbo.Call.call_transfer, dbo.Call.call_response, dbo.Priority.name AS priorityName, dbo.Call_Status.name as Call_Status,
dbo.Station.station_name, dbo.City.city_name, dbo.Protocol.name AS protocolName
FROM dbo.City INNER JOIN
dbo.Call INNER JOIN
dbo.Priority ON dbo.Call.priority = dbo.Priority.priority_id ON dbo.City.city_id = dbo.Call.city INNER JOIN
dbo.Protocol ON dbo.Call.protocol_category = dbo.Protocol.id LEFT OUTER JOIN
dbo.Station INNER JOIN
dbo.Ambulance ON dbo.Station.station_id = dbo.Ambulance.ambulance_station ON dbo.Call.amb_id = dbo.Ambulance.ambulance_id
INNER JOIN
dbo.Call_Status ON dbo.Call.call_status = dbo.Call_Status.call_status_id
WHERE dbo.Call.user_id=#LocUserId and dbo.Call.call_status=2
SET FMTONLY ON
END
This is the query plan.
Is there a way to make it to respond faster?

How do I modify a Stored Procedure to Join an additional table?

I have a fairly complex Stored Procedure that is joining several tables together, but I need yet another column called in from a table that is yet to be joined.
Here's the Stored Procedure as it stands:
CREATE PROCEDURE [rpt].[PlannerShipToLocations_ds1]
AS
BEGIN
SET NOCOUNT ON;
DECLARE #sql nvarchar(4000)
,#DateStart nvarchar(10) = '2015-01-01'
DECLARE #t TABLE (
[PCN] int
,[Part_Key] int
,[Customer_Address_No] int
PRIMARY KEY CLUSTERED (
[Part_Key]
,[Customer_Address_No]
,[PCN]
)
)
SET #sql =
'SELECT *

INNER JOIN [Sales_v_Shipper_Status_e] AS ss
ON s.[PCN] = ss.[PCN]
AND s.[Shipper_Status_Key] = ss.[Shipper_Status_Key]
INNER JOIN [Sales_v_Shipper_Line_e] AS sl
ON s.[PCN] = sl.[PCN]
AND s.[Shipper_Key] = sl.[Shipper_Key]
WHERE 1 = 1
AND ss.[Shipped] = 1
AND s.[Ship_Date] >= ''''' + #DateStart + '''''
;'')'
INSERT INTO #t
EXECUTE sp_executesql #sql
;WITH base AS (
SELECT DISTINCT u.[Last_Name] + ', ' + u.[First_Name] AS [Planner]

) a

FROM base t1
GROUP BY t1.[Planner]
,t1.[Customer Code]
,t1.[Customer Name]
ORDER BY [Customer Code]
,[Planner]
,[Customer Address Code(s)]
END
GO
I've bolded the sections that are my best guesses about how to go about joining this additional table, I recognize that I wouldn't use all of them but I wanted to show my thoughts. To break it down:
1.) [plx].[Common_v_Customer_Address_e] a AND [plx].[Common_v_Country] xxx are the two tables I need in order to call [Country] out by name. I essentially need to add this as a column displayed on the report and eventually will need to sort on it as well (I'll probably add it to ORDER BY at the end).
2.) I'm not sure if I need to be joining [plx].[Common_v_Country] xxx within the OUTER APPLY or if it needs its own separate INNER JOIN or what. I've illustrated and commented out both here. So far everything I've tried results in "The multi-part identifier 'xxx.Country' could not be bound."
Thanks for the help.
I've tried modifying the OUTER APPLY to include the new table. I've tried creating my own new INNER JOIN. I've tried creating my own new OUTER APPLY.

select all records from left table that do not exist in right table

I am working on sql server I have two tables and I need to return records from the left table which are not found in the right table for that I am using left join like below query,
select #MID=MID,#MName=Name,#PID=PID,#PName=PName,#DID=DID from #CompanyDataInfo where id=#MCount
insert into #temp SELECT Top(1) f.Name,f.PID,f.PName,v.* FROM #CompanyDataInfo f
left join Employee v on v.Id=f.ID and v.DID=f.DID
where v.Id =#MID and v.DId = #DId and v.PId = #PId and v.CId =#CId and DATE_TIME between DATEADD(minute,-555,GETDATE()) and GETDATE() order by DATE_TIME desc
Result should be all rows from #CompanyDataInfo table while no record found in Employee table for related ID, I googled and use "v.Id is null" but not getting expected result
Is there any solution greatly appriciable
Thanks In advance
Your query is not using left join in correct way. You are using your right table reference in where clause. I try to correct it below but I don't have full information about your table schema. Please try this-
select
#MID = MID,
#MName = Name,
#PID = PID,
#PName = PName,
#DID = DID
from #CompanyDataInfo
where id = #MCount
insert into #temp
select
f.Name,
f.PID,
f.PName,
v.*
from #CompanyDataInfo f
left join Employee v on v.Id=f.ID and v.DID=f.DID
where f.Id = #MID and
f.DId = #DId and
f.PId = #PId and
f.CId = #CId and
f.DATE_TIME between DATEADD(minute,-555,GETDATE()) and GETDATE() and
v.Id is null
order by f.DATE_TIME desc
Add ...and v.Id is null to your where clause.

function or stored procedure for bulk insert in table by sets

how can i convert the following to teradata stored procedure or some function :
WHILE EXISTS (SELECT * FROM #temp_set1)
BEGIN
/*group of statemnts :delete insert etc
like */
INSERT INTO #temp_set
SELECT TOP 200 * FROM #temp_set1;
INSERT INTO Activepull
as select * from #temp_set1
and this should occur for each set of 200 untill all inserts
end;
There are more than 60000 rows in #temp_set1 so want to insert by sets.
Thanks.
Written on my phone, but I would use the over expression. It creates a kind of pseudo Identity column that you can then use to paginate. And you can even choose the order based on an order by clause.
Declare #IntervalSize int = 100
Declare #BeginSet int = 0,
#EndSet int = #IntervalSize
While #Counter < (Select Max(ROW_NUMBER() OVER (ORDER BY someColumn desc) From #temp_set1)
Begin
Insert Into #temp_set
Select *, Row_Number() Over (Order By someColumn desc) As MyIdentity
Where MyIdentity Between #BeginSet And #EndSet
Select #BeginSet = #BeginSet + #IntervalSize,
#EndSet = #EndSet + #IntervalSize
End

How to write procedure with several output parameters?

I have created this procedure but this is throwing error.
CREATE PROCEDURE GetSurrenderPolicyDetails
#policy_Id int,
#name nvarchar(50) output,
#policy_Amount Decimal(10,2) output,
#premiumPaidTillDate Decimal(10,2) output
AS
BEGIN
SET NOCOUNT ON;
SELECT
#name = Policy_Details.Name,
#policy_Amount = Insurance_Policy_Details.Policy_Amount,
#premiumPaidTillDate = SUM(Payment_Premium_Details.Premium_Amount)
FROM
Policy_Details
INNER JOIN
Payment_Premium_Details ON (Policy_Details.Policy_Id = Payment_Premium_Details.Policy_Id)
INNER JOIN
Insurance_Policy_Details ON (Policy_Details.Ins_Id = Insurance_Policy_Details.Ins_Id)
WHERE
Policy_Details.Policy_Id = #policy_Id;
END
GO
The error says
Column 'Policy_Details.Name' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Well, the error is pretty clear: you have a SUM() aggregate in your SELECT, so therefore, you need to use GROUP BY for the other columns in your SELECT statement:
SELECT
#name = Policy_Details.Name,
#policy_Amount = Insurance_Policy_Details.Policy_Amount,
#premiumPaidTillDate = SUM(Payment_Premium_Details.Premium_Amount)
FROM
Policy_Details
INNER JOIN
Payment_Premium_Details ON (Policy_Details.Policy_Id = Payment_Premium_Details.Policy_Id)
INNER JOIN
Insurance_Policy_Details ON (Policy_Details.Ins_Id = Insurance_Policy_Details.Ins_Id)
WHERE
Policy_Details.Policy_Id = #policy_Id;
GROUP BY
Policy_Details.Name,
Insurance_Policy_Details.Policy_Amount,
your problem isn't your output parameters, but your join clauses; Instead, try something like:
INNER JOIN Insurance_Policy_Details
ON Policy_Details.Ins_Id = Insurance_Policy_Amount.Ins_Id
INNER JOIN Payment_Premium_Details
ON Policy_Details.Policy_Id = Payment_Premium_Details.Policy_Id

Sql Server queries optimization techniques

My Stored Procedure takes a very long time to execute.
Can anyone suggest me what I can do to speed up the stored procedure, apart from using some good practices for writing down the queries.
I've heard about creating indices, but I'm not sure what are they.
Please suggest all the best ways to speed up my queries.
Thanks

Here are a few:
You should have indexes for every column in a WHERE clause. See
your SQL language for how to do it.
Learn how to EXPLAIN PLAN and see what's slow.
Stored procedure languages are functional, not set based. Use JOIN and don't fall into the (n+1) query/iteration trap.
Understand how using certain functions force you to TABLE SCAN in a WHERE clause.
