AFAIK decimal(4,2) can hold the range (-99.99,+99.99), and not 123.4

I am getting an error when I run the following query:
"SELECT TICKET-STORE, TICKET-ACCT-MANAGER, TICKET-TYPE, TICKET-CONTRACT-DATE, TICKET-NEXT-DUE-DATE, TICKET-LAST-PAID-DATE, DateDiff('d',2009-11-08,[TICKET-NEXT-DUE-DATE]) AS Expr1, TICKET-TICKET-NBR FROM TICKET WHERE (TICKET-TYPE ='O')"
The error is "Invalid argument to Function. Function name is DateDiff"
The 'd' is a standard argument, The date is standard, and so is the data field [TICKET-NEXT-DUE-DATE].
Here is how I have it in the code:
SELECT TICKET-STORE, TICKET-ACCT-MANAGER, TICKET-TYPE, TICKET-CONTRACT-DATE, TICKET-NEXT-DUE-DATE, TICKET-LAST-PAID-DATE, " +
"DateDiff('d'," + strDate + ",[TICKET-NEXT-DUE-DATE]) AS Expr1, TICKET-TICKET-NBR FROM TICKET WHERE (TICKET-TYPE ='O')
This statement I took straight out of MS Access.
Any help would be appreciated!

within SQL statements literal dates need delimiters, either ' or # or [] depending on DB.

Thanx Luc! That brought me to another error of Invalid Function Name. Function name is DATEDIFF??? Isn't datediff() a standard function?
As I said before, the same string works in Access....
Here's what the string looks like now:
"SELECT TICKET-STORE, TICKET-ACCT-MANAGER, TICKET-TYPE, TICKET-CONTRACT-DATE, TICKET-NEXT-DUE-DATE, TICKET-LAST-PAID-DATE, DATEDIFF('d','2009-11-08','2009-11-08') AS Expr1, TICKET-TICKET-NBR FROM TICKET WHERE (TICKET-TYPE ='O')"
Thanx!

You now have to many quotes. It should be one of the following:
DATEDIFF(d,'2009-11-08','2009-11-08')
Or
DATEDIFF(dd,'2009-11-08','2009-11-08')
Or
DATEDIFF(day,'2009-11-08','2009-11-08')
Of course this is a poor example as datediff of the same dates is always 0.
If you have knowledge, let others light their candles at it.

True, bad example..I was just trying to troubleshoot, so I just pasted in the same date. I saw the bad quotes and changed that:
"SELECT TICKET-STORE, TICKET-ACCT-MANAGER, TICKET-TYPE, TICKET-CONTRACT-DATE, TICKET-NEXT-DUE-DATE, TICKET-LAST-PAID-DATE, DATEDIFF(d,'2009-11-08','2009-11-08') AS Expr1, TICKET-TICKET-NBR FROM TICKET WHERE (TICKET-TYPE ='O')"
But I am still getting an error stating:Build Error : Invalid Function Name, Function name is 'DATEDIFF'.
??

DateDiff is an SQL function, how can a C#, C++, or VB compiler complain about it?
FWIW: If your SQL statement spans more than a single line of source code, you should take appropriate measures, which depend on your programming language.
Please show actual code and error message. And check the line numbers as to where the error occurs.

I shortened up the SQL a bit, but I am getting the same error The error is on DbReader = DbCommand.ExecuteReader():
OdbcConnection DbConnection = new OdbcConnection("DSN=rsss");
OdbcCommand DbCommand = DbConnection.CreateCommand();
DbCommand.CommandText = "SELECT TICKET-STORE, DATEDIFF(day,'" + strDate + "','" + strDate + "') AS EXP FROM TICKET";
DbConnection.Open();
try
{
DbReader = DbCommand.ExecuteReader();
while(DbReader.Read())
{
intStore = Int32.Parse(DbReader["TICKET-STORE"].ToString());
}
}
catch(OdbcException caught)
{
Console.WriteLine(caught.ToString());
Console.Read();
DbConnection.Close();
}
Here is the error:
System.Data.Odbc.OdbcException: ERROR [HY000] Build Error: Invalid Function Name. Function name is 'DATEDIFF'.

I don't see anything wrong, but then I'm not a DB expert at all.
However, from earlier messages, I think you target SQL Server 2000, and this[^] seems to suggest you use SqlConnection instead of OdbcConnection. Which would mean a different connection string, some C# code changes, and probably some SQL changes too.

I figured it out. The contacted the company who produced the connector. It does not support a DateDiff() function :-/
I also contacted the third party vender and they stated that they have a built in function for it. Hopefully that works.
Thanks a lot for your time and help!

Good Day All
am restoring a Database Programatically in Sql. Now if the backup is located in the remote machine i use a Share
\\Vuyiswa\MyShare\
but i will get the Following Error
Exception caught in: ExecuteStoredProc: The file "\\Vuyiswa\Databases\\REmoteTest33.mdf" is on a network path that is not supported for database files. File 'TNGoedit_Data' cannot be restored to '\\Vuyiswa\Databases\\REmoteTest33.mdf'. Use WITH MOVE to identify a valid location for the file. The file "\\Vuyiswa\Databases\\REmoteTest33_log.ldf" is on a network path that is not supported for database files. File 'TNGoedit_Log' cannot be restored to '\\Vuyiswa\Databases\\REmoteTest33_log.ldf'. Use WITH MOVE to identify a valid location for the file. Problems were identified while planning for the RESTORE statement. Previous messages provide details. RESTORE DATABASE is terminating abnormally. Database 'REmoteTest33' does not exist. Make sure that the name is entered correctly.

That part of the error says that you cannot restore a backup that's sitting on a network drive. I suggest you copy the file locally, and restore from there

i know that
but i needed a Solution for this. This means that every time i do a restore i need to copy the filer over and if the Servers are not in the same place and the backup is big this can be a lengthy process.

That's probably also the reason why you cannot restore from a network-drive. It would be slow, since every read would be reading from a remote drive over TCP/IP. I guess that it's faster to download the really big file and restore from a local drive, then try to restore from a network path (which may temporarily loose connectivity!)
The software refuses to use a network path. Solutions mean either changing the software, or the network path. Out of those two options, the path is probably the easier on to change.

Hi All,
I am trying to find a solution on gettting records from One database in to another one.So that i can only rely on one database for any information instead of having to login in to two databases.
Any idea will be much appreciated.
Many thanks

You can write a program to do the job, then schedule it using the scheduler (get access to it from Control Panel) to make it run every day at midnight.

Thanks so Much for your reply.Its much apprecaited.
Let me expalin clearly what i need. I have two mirrored databases exactly the same to each other.There is few table that contains different records.I want to copy the data from Database A to Database B
How can i do that?I would appreciate if you can give me a detailed step.
Many thanks for your help.

Currently I don't have much time to do this. I used the code (that I pointed out in my previous message) in my projects. I only needed to modify a little to solve some Microsoft Access problems. It worked very well.
What you need to do is to build a standlone program to conduct the copy operation, then schedule it using the Windows Scheduler. I can only guarantee that the code to copy tables across databases works well, whether they are of the same type (e.g. both of them are MS Access) or different (can be Oracle, MS SQL Server, MySQL Server, etc).
The hard part, though, is the creation of the table if it does not exist in the target database before the copy operation starts. This, of course, is assuming that you don't plan to create the table(s) by hand. You have to write that part of the program. However, from your description of your project, this problem does not exist. You already have all the tables ready.
I would suggest using C# and ADO.NET to write this program, since it will save you lots of time.

Thanks so much it really works for me.What i want to find out now is How can i make sure that the copy process doesnt copy data already copied when doing it on another session.
If the copy is done onece during the second operation will it know what records to add?
How do you also solve the problem when the two databases run in Different virtual private networks?
Lastly,when you copy the data it doesnt really check what has been copied before.So all the information will be be copied again every time the code runs.
Many thanks

I am looking for a way to derive a weighted average from two rows of data with the same number of columns, where the average is as follows (borrowing Excel notation):
(A1*B1)+(A2*B2)+...+(An*Bn)/SUM(A1:An)
The bold part reflects the same functionality as Excel's SUMPRODUCT() function.
My catch is that I need to dynamically specify which row gets averaged with weights, and which row the weights come from, and a date range.
|
|
|
|
|
Do the whole thing in a stored proc.
Create a temp table to hold the interim calculations and then do your processing on the temp table (table var in SQL Server). Your design seems a little odd if you hold both the values to be averaged and the weighting factor in the same table.
Row_number() is very useful in this type of processing.
|
|
|
|
|
If I have understand your requirement, then try this
SET DATEFORMAT dmy
declare @tbl table(A int, B int,recorddate datetime,KPI varchar(50))
insert into @tbl
select 1,10 ,'21/01/2009', 'Weighty'union all
select 2,20,'10/01/2009', 'Tons Milled' union all
select 3,30 ,'03/02/2009', 'xyz'union all
select 4,40 ,'10/01/2009', 'Weighty'union all
select 5,50 ,'05/01/2009', 'Tons Milled'union all
select 6,60,'04/01/2009', 'abc' union all
select 7,70 ,'05/01/2009', 'Weighty'union all
select 8,80,'09/01/2009', 'xyz' union all
select 9,90 ,'05/01/2009', 'kws' union all
select 10,100,'05/01/2009', 'Tons Milled'
select SUM(t1.A*t2.A)/SUM(t2.A)Result from
(select RecordDate,A,B,KPI from @tbl)t1
inner join(select RecordDate,A,B,KPI from @tbl t)t2
on t1.RecordDate = t2.RecordDate
and t1.KPI = t2.KPI
Hope this helps
