Hi,
I am developing an app that manages race results and I need some advice on the best way to store the race times in sql server. As far as I know, the best datatype would be datetime.
With the data stored, I will need to be able to do things such as:
rank the results based on the race time
I want to be able to read and update a value in the database without entering a race condition.
For example:
User #1 reads a row from the database, changes a value then writes the value back.
User #2 reads the same row AFTER user #1 has read it, but BEFORE user #1 writes it back. User #2 then changes the value and writes it back, overwriting the value that user #1 wrote.
I thought I could do this with transactions, but it just makes user #2 wait until user #1 is done writing before user #2 can write. It doesn't stop user #2 from reading while user #1 has it out.
Does that make sense?
Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?
View 6 Replies View RelatedI have set up an sql server which has a column called times. This column is to hold race times however when i enter times such as 22:20:89 with the 89 being milliseconds i am not bale to input this it will only allow me to put times in where milliseconds are below 60. This is a problem especially for the shorter races where half a second is a big difference.
Thanks Mike
When trying to connect to a server on a slow connection (satelite), Enterprise Manager times out. I am able to connect with Query Analyzer. Tried to change 'remote login timeout', but that did'nt help, EM seems to timeout long before this value is reached. Any ideas ?

SQL Statement.
Adding times together.
I am trying to add a list of times together retrieved from my database.
They are from seperate records in the same table.
They are in a date format e.g. 01-Jan-2006 03:45:00, what I want to do is ignore the 01-Jan-2006 part as well as the :00 AM part and focus on the hours and minutes. I wish to add these up e.g. 03:45 + 04:45 = 08:30. Is there an easy way of doing this?
Below is the SQL statement of getting times from my database if its any help.

Hello everyone,
I have an odd issue and I can't seem to figure it out. I am using SQL Server 2005 and I am using Transactions in combination with Try/Catch blocks. My query (executing the stored procedure) never seems to finish the query in query analyzer. I have removed all statements that exectute or select, etc upon the database except for a simple Select 'test' as test so I would have something in my Begin/End blocks. Below is my stored proc:
ALTER PROCEDURE [dbo].[ar_mainCheckRecon]
@tripID int,
@payment money,
@adjustment money,
@serviceType tinyint,
@checkTpId int,
@checkTlId int,
@checkNbr varchar(20)
AS
BEGINSET NOCOUNT ON;
BEGIN TRY
BEGIN TRAN select 'test' as test
END TRY
BEGIN CATCH
RAISERROR('Error commiting transaction', 16,1)
ROLLBACK TRAN
SELECT '0' as success
END CATCH
COMMIT TRANSELECT '0' as errorCode
END
I call upon the sproc by running this line in query analyzer:
exec ar_mainCheckRecon 433636, 0, 500, 0, 500, 0, 23
Is there something I am overlooking as to why the query keeps running and never stops? My current execution time is at 3 mins accoring to query analyzer!
Thanks,John
When using a SQL Server DateTime column to store just times, e.g. '6:00 PM' I've noticed some weird inconsistency.
If I insert a time in a SQL statement, such as... INSERT INTO myTable (StartTime) VALUES ('6:00 PM')
It winds up going in as '1/1/1900 6:00 PM'. This is okay. This is in fact what I want (unless of course the base day for sql server is in fact 12/30/1899, which is my next question).
If, on the other hand, I insert a time value by hand, using SQL Server Management Studio, then after I insert '6:00 PM' it winds up as '<Today's Date> 6:00 PM', i.e. '1/20/2008 6:00 PM'.
Also, if I insert it using a SQL Parameter, such as...
da.InsertCommand.Parameters.Add("@StartTime", SqlDbType.DateTime, 8, "StartTime")
...Then, if StartTime is 6:00 PM again, it also winds up going in as '<Today's Date> 6:00 PM'.
Is there a way to control this behavior (other than to programmatically append a base date to the time I'm inserting)?
Finally, what is the base day for SQL Server 2005? Is it 1/1/1900 or 12/30/1899? I think I've seen both.
Thanks!

Anyone know of an easy way to work with datetime columns ignoring the time part.
I want to "group by" the date so it is vital that the time part goes.
But I still want to work with the resulting date as a date (i.e. use date functions) so I would prefer to keep the datetime data type.
Hi
I'm new in SQL. I have a big problem
Database: MSSQL 2000
I have two tables: (results) one with numeric results and one with names (importance_scale)
SELECT * FROM results
name i1 i2 i3 i4 i5
---- ---- ---- ---- ----
john 2 1 2 2 2
anna 0 2 2 2 2
phil 2 2 2 2 2
dave 1 0 2 2 2
SELECT * FROM importance_scale
imp_value imp_name
--------- ------------
2 very important
1 important
0 not important
i1,i2 etc. value it is a imp_value from table 'importance_scale'
I would like to make report which will show all results in this format (in example only first record):
name i1 i2 i3 i4 i5 etc.
----- --- --- --- --- ---
john very important important very important very important very important etc.
I was thinking about using CASE I don't want use cursor. What is the best way?

I want to enter times for running event performances (like 10:26.35 for a person's 2-mile time, for instance). I am using sql server 2000. This is an ongoing concern for me since I do a lot of work with running events. Can someone give me some direction as to how I can best deal with this?
The datetime data types do a lot of converting to 'time-of-day' and that is not what I want. For instance, if I enter a 2-mile time of 10:26.35 (a pretty typical 2-mile time) my db converts it to 10:26:35 AM.
If I use varchar data type there is a ton of code to write when I want to sort the data.
Thanks!

I have some code that opens a SqlConnection to a MSSQL 2000 database. The connection opens great everywhere except inside my implementation of IPasswordProvider.GetPassword(). It just hangs there, and then throws a timeout. I have tried using both trusted connections, and userid/password connection strings. I notice that within GetPassword, the authenticated user is COMPUTERNAMEASPNET, whereas in the web method that actually is getting called, the authenticated user is my personal user account. The SqlConnection opens fine in the actual web method.
Can anyone tell me what could stop a SqlConnection from opening while inside GetPassword()? I kinda need to look up passwords in the database.
Hi All...
if i had the following sp...
*******************************************************
create procedure my_insert (param1 int, param2 int, paramx int)
as
...
complicated insert routine
...
return
*******************************************************
and then i wanted to exec this sp in another procedure i would have
exec my_insert( 1_value, 2_value, 3_value )
My question is how could i exec this will the result set of a select.... something like this
exec my_insert (select 1_value, 2_value, 3_value from another_table).
I know i could have this in an insert result type statement ie...
insert into dest_table (select 1_value, 2_value, 3_value from another_table)
but my insert routine is quite complicated and carries out some other functions so I would like to call (exec) a sp rather than repeating the complication in the select statement
Many Thanks

I have an VB.NET web app which performs a fairly complicated SQL query. It seems in the morning, the 1st time the page is loaded (and query executed) it takes up to 10-15 seconds to complete loading. Sometimes it even times out. However anytime after that, the page loads up (even from another computer) in about 4-5 seconds. Can someone explain the reason for this and how I might fix the load times in the morning?
Thanks
The developers of frond end ask to select only one row from one table, but many times, such as 10. That means the output has 10 rows and same.
Any suggestion will be appreciated.

Hello,
I see the following problem regarding a SQL function that returns a value.
We have the following query
SELECT c.Id_Customer, c.Name
FROM t_Customers c
WHERE c.Id_Status = fn_GetParameter('ID_Status.Active')
The idea is not hardcoding the status and other values on each query, and, since SQL Server does not support the definition of constants, we have a table with many parameters and we search them.
We defined the function "WITH SCHEMABINDING" and the SQL Server recognizes it as DETERMINISTIC, so I do not understand why it executes the function as many times as records in the t_Customers table, since every time it is executed it returns the same value.
We could define a variable, assign the value returned by this function to this variable and then use it on the SELECT, but this approach is useless if we use SQL instead of stored procedures (for example, in reports from reporting / BI tools).
Any explanation about why SQL chooses to execute the function many times, and any hint regarding how to make SQL Server execute only once the function will be very appreciated.
Thanks in advance,
Lisandro.
Hey, everyone. I'm new to database programming in SQL Server, and I currently have the 2005 express edition. I was wondering whether it was possible to check whether one time (h:mm AMPM) is less or greater than another (the other in this case being the GETDATE). I already made a user-defined function in order to extract the time from a datetime, since SQL Server doesn't support the time data type. The thing is that the value is returned as a char(8) in the 12-hour style HH:MM AMPM format and I'm sure that's what's screwing up the comparison function. What would I need to do to compare two times (24-hour or 12-hour, whichever is easier)?

Hi there, I'm a little bit stumped on this one.
I have a column in a table that records when the date and time of an event took place.
Table Name: Chronicle
Column Name: Created (of type DateTime)
I would like to select the Chronicle records that are between two dates.
(e.g. 1 May 2001 and 20 May 2001)
And I would like to select those records that are between two times.
(e.g. 6:00am and 1:00pm)
Does anyone know how to do this or have any pointers for me?
I can see it would be easier if I had the date in one column and the time in the other.
Can it be done without doing that?
cheers,
