Counting records with a specific date value - sql

Question

I want to get all records entered with specific day, for example today:
ALTER PROCEDURE [dbo].[SP_GET_QUEUESINFO_BY_DATE]
#date nvarchar = '2012-09-21'
AS
BEGIN
declare #dateStart nvarchar(50) = #date + ' 00:00:00.0'
declare #dateEnd nvarchar(50) = #date + ' 23:59:59.437';
declare #returnData table (allQueue int,inQueue int,outQueue int)
SELECT 'table1' as table_name, COUNT(*)
FROM Queue as Counts
UNION ALL
SELECT 'table2' as table_name,COUNT(*) FROM Queue as Counts
WHERE QueueDate BETWEEN #dateStart AND #dateEnd
AND QueueNumIn != 0
END
Edited :
I Edited my code now it works :
ALTER PROCEDURE [dbo].[SP_GET_QUEUESINFO_BY_DATE]
AS
BEGIN
declare #date2 datetime
set #date2= '2012-09-21'
SELECT 'AllQueue' as table_name, COUNT(*)
FROM Queue as sdfds
UNION ALL
SELECT 'InQueue' as table_name,COUNT(*)
FROM Queue as sdfds
WHERE QueueDate >=#date2
AND QueueNumIn != 0
UNION ALL
SELECT 'OutQueue' as table_name, COUNT(*) FROM Queue as sdfds
WHERE QueueDate >=#date2
AND QueueNumOut != 0
END
It returns three records:
One problem is that the second column has no name. Why? Also, I want to return just one record that has three rows, not 3 separate records that have 2 fields.

Answer 1

you need to cast your varchar to datetime. and i think you want to assign Counts alias to Count(*)
ALTER PROCEDURE [dbo].[SP_GET_QUEUESINFO_BY_DATE]
#date nvarchar = '2012-09-21'
AS
BEGIN
declare #dateStart DATETIME = CAST(#date AS DATETIME)
declare #dateEnd DATETIME = DATEADD(hh,24,CAST(#date AS DATETIME))
declare #returnData table (allQueue int,inQueue int,outQueue int)
select 'table1' as table_name,COUNT(*) as Counts from QUEUE AS tb1
union all
select 'table2' as table_name,COUNT(*) as Counts from QUEUE AS tb2 where QueueDate >= #dateStart and QueueDate < #dateEnd and QueueNumIn !=0
END

Answer 2

not sure why returning all if you only want those in the spetial date.
Also, is better not to use between in Dates
ALTER PROCEDURE [dbo].[SP_GET_QUEUESINFO_BY_DATE]
#date datetime = '2012-09-21'
AS
BEGIN
select count(*) as 'AllQueue' ,
sum(case when QueueDate >=#date and QueueNumIn != 0 THEN 1 else 0 end) as 'InQueue',
sum(case when QueueDate >=#date and QueueNumOut != 0 THEN 1 else 0 end) as 'OutQueue'
from Queue
END
this should work.
this will give you something like
Allqueue inqueue, outqueue

11 | 8 | 10

This Code Worked and is edited code from ElVieejo
ALTER PROCEDURE [dbo].[SP_GET_QUEUESINFO_BY_DATE]
AS
BEGIN
declare #date2 datetime
set #date2= '2012-09-21'
select COUNT(QueueID) ,
sum(case when QueueNumIn != 0 THEN 1 else 0 end) as 'InQueue',
sum(case when QueueNumOut != 0 THEN 1 else 0 end) as 'OutQueue'
from Queue where QueueDate >= #date2
END
