a loop that increments a value in the selection clause?

[Red_Wizard_Shot_The_Food]

I’m trying to make a loop that will select a count of all entries that have a "TimeIn" value on the date defined by an input parameter with an hour value between x & y. So the first pass through the loop would select a count of all rows with a TimeIn between 00:00:00 and 01:00:00 on the selected day ... The second pass will select a count of all rows with a TimeIn between 01:00:00 and 02:00:00. finally it will return counts for each hour in the day. This is my first attempt at loops in SQL so any push in the right direction would be much appreciated. Thanks.

There is a better way to do this.

SELECT
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '00:00:00' AND '01:00:00') AS 'Time1',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '01:00:00' AND '02:00:00') AS 'Time2',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '02:00:00' AND '03:00:00') AS 'Time3',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '03:00:00' AND '04:00:00') AS 'Time4',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '04:00:00' AND '05:00:00') AS 'Time5',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '05:00:00' AND '06:00:00') AS 'Time6',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '06:00:00' AND '07:00:00') AS 'Time7',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '07:00:00' AND '08:00:00') AS 'Time8',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '08:00:00' AND '09:00:00') AS 'Time9',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '09:00:00' AND '10:00:00') AS 'Time10',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '10:00:00' AND '11:00:00') AS 'Time11',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '11:00:00' AND '12:00:00') AS 'Time12',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '12:00:00' AND '13:00:00') AS 'Time13',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '13:00:00' AND '14:00:00') AS 'Time14',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '14:00:00' AND '15:00:00') AS 'Time15',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '15:00:00' AND '16:00:00') AS 'Time16',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '16:00:00' AND '17:00:00') AS 'Time17',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '17:00:00' AND '18:00:00') AS 'Time18',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '18:00:00' AND '19:00:00') AS 'Time19',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '19:00:00' AND '20:00:00') AS 'Time20',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '20:00:00' AND '21:00:00') AS 'Time21',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '21:00:00' AND '22:00:00') AS 'Time22',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '22:00:00' AND '23:00:00') AS 'Time23',
(SELECT COUNT(TimeIn) FROM TableName WHERE TimeIn BETWEEN '23:00:00' AND '24:00:00') AS 'Time24'
FROM TableName

If you have SQL-Server then

select convert(varchar(13), TimeIn, 120) + ':00', count(*)
from MyTable
where TimeIn between @x and @y
group by convert(varchar(13), TimeIn, 120) + ':00'
order by 1

SQL is best for set operations. You can do loops and cursors but they tend to be slower and are harder to code. Regards Andy

Ohh so that is better than mine? Cool... :cool:
