Probably not directly, but there is nothing stopping you from creating a Windows DLL that wraps the ADO class heirarchy in a set of public functions. This DLL could then be used in straight C.

This DLL is not only be used by C, but also other client languages like Delphi, Borland C++, VB.NET etc. I am still figuring out how to wrap this ADO in the DLL so that it can be called by all client languages. Do you have any sample code or references that I may refer? Thanks.

DateTime Updating Problem in sql?

below is the query that is a part of a sproc .All table
fields and values are ok. When the mentioned Sproc. is
called in query analyzer it executes well and update all
fields of the table used in UPDATE statement
.
UPDATE Emp_Schedule
SET IOS = 0, HoursWorked = @WorkTime, COA =getdate()
WHERE (Emp_Id = @EmpID) AND (S_Id = @ShiftId) AND (DT =@DayTime)

PROBLEM arises when i call this procedure from C# code all fields are updated Except the COA(DateTime) field.Whats the problem. SProc runs well both in debug mode and normal mode in query analyzer and do updates the values. But when i call in C# only datetime field COA is not Updated? Plz solve this.
THNX IN Advance.

Is it possible that this is a permissions problem? The user that executes the C# code, do they have execute permissions on the function?

Hey everybody,
I know this a pretty silly question but I totally blanked. I'm looking to remove duplicate results from the results set (NOT the table).

Say I have a query like so:
SELECT SomeNumber FROM MyTable ORDER BY SomeNumber ASC
returns the following set:
1
1
1
2
2
3
4

But I want it to return:
1
2
3
4

What extra criteria would I add to the query?

Thanks in advance for your help.

Help Me plz abt this dateTime UDF_Function?

majidbhutta1-Dec-05 15:32

1-Dec-05 15:32

below is the function that compares only time .there are 3 datetime variables.
@StartTime datetime
@EndTime datetime
@DayTime datetime

@StartTime is always less than @EndTime regardless of its
dates.and @DayTime may be any time. We have to calculate
whether @DayTime lies between @StartTime and @EndTime or
not. And on its behalf we return a value.
if @DayTime lies between @StartTime and @EndTime return 1
else return 0.But tested with these values result is not ok.
set @StartTime='12/1/2005 12:30:49 PM'
set @EndTime='12/2/2005 4:30:49 AM'
set @DayTime='2005-12-02 00:56:02.730'
select dbo.udf_IsShiftValid(@StartTime,@EndTime,@DayTime )

it returns 0 where i think it should return 1. plz correct
me where m i wrong.

Actually i have to use this function on CheckInShfit event of the Employee. @StartTime and @EndTime are the time of the shifts that have already been defined in the database very ago. Now whenever Employee ChecksIn we have to confirm wheather he is entering Between his shift timing that have been Defined already in the database, if his CheckInTime (only time not date) @DayTime lies between his @StartTime and @EndTime then he is allowed to enter (i.e 1) else Not(0).
Now keeing in view the baove Scenario, plz guide me
plz modify this function so as it returns 1 if the @DayTime

Lies Between @StartTime And @EndTime else one( BUt keep in

Mind i m required to compare only time not the dates and

@startTime value is always less than @EndTime value)

CREATE FUNCTION dbo.udf_IsShiftValid(@StartTime datetime,

@EndTime datetime,@DayTime datetime)
RETURNS int AS
BEGIN
DECLARE @RtValue AS int

IF
convert(varchar,@DayTime,114)>=
convertvarchar,@StartTime,114) AND

convert(varchar,@DayTime,114)<
(convert(varchar,@EndTime,114)
BEGIN
SET @RtValue=1
END
ELSE
BEGIN
SET @RtValue=0
END

RETURN @RtValue
END

Transfer local sql database to web-server

1-Dec-05 5:46

Once i have created a database in the local sql server, how can i upload it to my website? can I simply copy the two database files to my relevant folder on the web-server (in a manner similar to access database)? Or is there any special method? Is there any detailed article on this?

Secondly, after uploading this database to web-server, how can i update it - locally or online only? can i continue to have a copy in my local sql server, which i can update and again upload the updated version?

thanks in advance

1. Easy method would be to take a backup, upload it and restore.

OR

2. Use database management tools like Red Gate tools www.red-gate.com[^]

OR

3. Generate DDL, DML scripts, upload and run it on destination server.

Thanks for your reply.

But is it possible to restore from a backup when I do not have administrative rights on the web-server? I just have the user-account with dsn information.

Secondly, if I use the DDL / DML scripts, how I can them from my virtual folder on the website?

Thanks again.

You need necessary permission in database. First check if your hosting company lets you connect vi EM. Then FTP your backup file to your folder and use EM to restore it.

Does your host have any web based data management tools? I doubt they'd let you run isql/osql.
