This is the 3rd question on the same topic. You should stick to 1 thread for 1 topic. Ive also pointed out the forum guidlines which ask you to use descriptive subject lines . "sql function" does not qualify as descriptive in a sql forum. The forum guidlines should also include the request to put code within formatted code blocks for ease of reading (if it doesnt it should).

Furthermore, you have not given any response to the answers youve been given below, so we have no idea if were even on the right track.

Lastly, Ive already answered this question below.

I required only time in select query from datetime field in format like:
2:20:55 AM.

Pls help me

That is presentation logic, use your presentation layer to format a datetime instance appropriately.

This should start you off:

var now = DateTime.Now;
Console.WriteLine(now.ToString("h:mm:ss"));

More info: Date / Time format strings[^]

edit: read the forum guidlines for posting messages; pay specific attention to the subject line requirements.

He may have a specific (and valid) reason for needing times in his sql.

I highly doubt it. See his post below this one.

In addition, I cannot think of a valid reason to format a date, or time, into a string in sql. can you?

I don't have a problem with the splitting of the date/time I can think of a number of valid reasons to do that in SQL. What had I missed was that he had stored the data as text, I assumed it was datetime.

There are a number of ways you can do this.

Here is one:

select convert(nvarchar, getdate(), 8) TheTime

Here is another:

select substring(convert(nvarchar, getdate(), 22), 10, 11) TheTime

FIRSTTIMEIN LASTTIMEOUT
7:10:09:000PM 9:40:45:000PM
10:20:32:000PM 12:15:27:000AM
From this,i will have to get only 7:10:09:000PM as FIRSTTIMEIN and 12:15:27:000AM as LASTTIMEOUT.I used min and max function.but it was not possible.help me

Re: SQL FUNCTION USING DATE TIME

Re: SQL FUNCTION USING DATE TIME

MIN and MAX are indeed the right functions to use, however, for them to work properly the data must be stored in a DATETIME field, because using strings to store those times will obviously yield string-based results for min & max. There is no way to calculate the min and max times from strings representing dates.

Secondly, in order ot know that 12:15am is after 7:10pm you must also store the date date part along with the time part.

Here is a simple test script that shows the process (and returns the results you want). You'll notice ive used yesterdays date for the 3 values before midnight, and today's date for the one after midnight.

WITH data(firstTimeIn,lastTimeOut )
AS
(
	SELECT CAST('4 july 2010 7:10:09:000PM' AS DATETIME),CAST('4 july 2010 9:40:45:000PM' AS DATETIME)
	UNION 
	SELECT CAST('4 july 2010 10:20:32:000PM' AS DATETIME),CAST('5 july 2010 12:15:27:000AM' AS DATETIME)
)
SELECT 
	MIN(firstTimeIn) as firstTimeIn,
	MAX(lastTimeOut) as lastTimeOut 
FROM data

Result:
firstTimeIn: 2010-07-04 19:10:09.000
lastTimeOut: 2010-07-05 00:15:27.000

If at all possible don't use that string format. It will break in other locales.

'2010-07-04 22:20:32:00' is the better format. It is always parsed correctly no matter what the locale.

You don't say! Roll eyes | :rolleyes:

I was providing test data for the OP, which incidentally will parse in all locales as the month names are fully qualified.

Dynamic SQL and the Crystal Report

4-Jul-10 19:09

Use dateparts to remove the time component of the fields with time values.

You can also do a double convert > varchar using a formater convert(varchar(20),date,103), then convert the result back to datetime format and use that in the report

I want to know that which is better to save a graph either XAML or SQL databse.

3-Jul-10 20:38

I think you will find the MS discovery will also not get and fields either. I'm not sure (never read up on it) just what magic they use to get the columns but it cannot work with dynamic sql. This seems perfectly reasonable to me as dynamic sql allows you to change the column names - 1 dead report.

Usually dynamic sql indicates a change of underlying object, database, server, table or column structure. Unless it is columns then just dummy up a proc for design purposes.

Complicated size calculation

2-Jul-10 22:39

The answer to this is, as always, it depends. It depends on the quantity of data, the portability required, the type of data, the type of application and possibly a few others.

As a starter I would consider XML (XAML is for markup) only for minimal data that is only relevant to the current user on the current machine.

All,
I have a slightly complicated issue, I have a Sql 2005 DB which is like 20GB right now, It has different tables related like Projects->Facilities->Locations->Pictures
What I am looking for is the size occupied by an individual project,
Lets say Projects Table has the following
1 Sample Project One
2 Sample Project Two

Facilities has the following
1 1(ProjectId) Facility One
2 1(ProjectId) Facility Two
3 2(ProjectId) Facility Three

and Locations and pictures are related similarly using FacilityId and LocationId

Now I need the data occupied by the entire Project One including the data related to Project One in all other tables.
Hope this is clear,
I welcome any suggestions,
Thanks in advance

Never having addressed this requirement this is a guess only.

I would take a look at the properties in SSMS, I'm sure the tables have size and rowcount in their properties, this means it is stored in a sys table somewhere. It now becomes a search and mathematics problem. Good Luck
