Try something like this
SELECT <br />
Tap_IsInPunch<br />
FROM TimeAtendancePunches tp1<br />
WHERE Tap_IsInPunch IS NOT NULL<br />
and Tap_DateAndTime_DT = (<br />
SELECT <br />
MIN(Tap_DateAndTime_DT)<br />
FROM TimeAtendancePunches tp2<br />
WHERE Tap_DateAndTime_DT >= @fromDateTime AND <br />
Tap_DateAndTime_DT <= @toDateTime AND <br />
Tap_IsInPunch IS NOT NULL<br />
and tp2.Tap_IsInPunch = tp1.Tap_IsInPunch )

Thank you Ashfield
That works perfectly. What you did there is called an alias correct? I have added a join to this query
to check a value in a different table. Thanks again Ashfield
|
|
|
|
|
You are welcome. Some would call it an alias, personally I would call it a correlated sub query.
BTW, just be warned if using SQL Server 2000, ther is a bug that means if you nest more than 4 deep with sub queries it doesn't work - and before I get a load of comments to the effect that you should never nest sub queries that deep, it was an experiment to see if you could

Hi.
I'm creating backup files of my database using SMO. The problem is that I can only store those files on the pc running the SQL Server.
Is there a way to get SMO to store the backup file on the pc running my SMO application?
Here is my code:
<br />
Backup backup = new Backup();<br />
backup.Devices.AddDevice("C:\\temp\\myBackup.bak", DeviceType.File);<br />
backup.Database = "MyDatabase";<br />
backup.SqlBackup(server);<br />
Thank you for any help!

You have to consider that running backup is not done by your PC, it is done by the server. So think like a server, you need to have your drive mapped to the server, when it looks at C: it is the SERVERS local drive.

That's Ok... My question was if somebody knows enough SMO to solve what I need...
The user may work on different pc's... I have to give him the possibility to create a backup file and store it on the pc where he is working (CD, USB drive,...) ...
Same way I need to send a backup file to the server from whichever pc in order to execute the backup.
Is it possible? Or is there any other solution?

AFAIK you are going to have to have a mapped drive from the server to the client, if the client changes you have a problem. Sorry, no solution from here.
Ahh
Have SQL create the backup to a shared server folder and then use a UNC path to copy to the local client using your UI.

int r = OracleHelper.ExecuteNonQuery(connection, CommandType.StoredProcedure, SpName, param);
r = int.Parse(param["TEMPID"].Value.ToString());
Error Cannot implicitly convert type 'System.Data.ParameterDirection' to 'System.Data.OracleClient.OracleParameter' (For TempId);

Hi we have been running the DTS package for Direct Deposits, for a while now and suddenly is very slow and data is not updated on applications for users.We get data from ftp files to the tables.
Thank you
|
|
|
|
|
This is more of a comment than a question! Not a lot to go on is there? To help we need to know a bit about the dts package, the tables etc etc.
A guess? Try checking your error messages fromt the dts steps.

Hi,
I have a column that contains varchar values, the structure that the values are built is always the same, first six characters is a string prefix, anything after the prefix must be int or it is invalid.
What I want to do is subtring the column starting at character 7 for the rest of the value, but how do I validate if that value returned by the substring is int.
something like if value is int, is there a way that I can do this?
So lets say the column contains the following values:
abcdef123321
abcdef78998745
abcdef4568547
abcdef123548/
it should only return the first 3 rows because the fourth row is invalid because of the "/" at the end
Thanks in advance

You can use the sql ISNUMERIC
declare @variable varchar(100)<br />
set @variable = 'abcdef78998745'<br />
select isnumeric(substring(@variable,7,datalength(@variable)-6))<br />
--returns 1<br />
<br />
set @variable = 'abcdef4568547'<br />
select isnumeric(substring(@variable,7,datalength(@variable)-6))<br />
--returns 1<br />
set @variable = 'abcdef123548/'<br />
select isnumeric(substring(@variable,7,datalength(@variable)-6))<br />
--returns 0 as not numeric
Hope this helps

I'm not getting any clue of why the crash is happening at this point. After opening for a long time, it just crashes at this point !!!!!
Appreciate if some body can shed a light on the reason, what all could be the reason.

I am trying to understand the impact of network traffic on data performance in my environment.
For example, if I am inserting 2 million rows into a database then how can I determine how much time is spent on network traffic? And how can I determine the savings of performing a batch update?
|
|
|
|
|
I don't know what to tell you about HOW to measure the network overhead as I am not a network professional, I imagine you'd have to inspect the packets going over the wire. But I CAN tell you that batches get exponentially faster than RBAR (row by agonizing row) transfers the more data you're working with. Imagine what the network overhead is for one round trip to your database. When you perform batches that overhead becomes a constant. But when you perform RBAR operations over the network that overhead is added for EVERY row. If you are working with that much data then it shouldn't even be a question of wither or not to batch update. Use BULK INSERT or SSIS/DTS but don't do it RBAR.

I have a stored procedure in oracle that looks like this:
<br />
PROCEDURE validate_master_account_id (v_master_account_id IN NUMBER, v_is_valid OUT NUMBER); <br />
And a procedure that looks like this:
<br />
public static bool TestProcedure()<br />
{<br />
string procedureName = "SMT.CPR_MASTER_ACCOUNT_PKG.validate_master_account_id";<br />
using (OracleConnection connection = new OracleConnection(AppSettings.ConnectionString))<br />
{<br />
connection.Open();<br />
<br />
using (OracleCommand command = new OracleCommand(procedureName, connection))<br />
{<br />
command.Parameters.Add("v_master_account_id", OracleType.Number).Value = 16793;<br />
command.Parameters.Add("v_is_valid", OracleType.Number).Direction = ParameterDirection.Output;<br />
<br />
command.ExecuteNonQuery();<br />
bool result = ((int) command.Parameters["v_is_valid"].Value) == 1;<br />
return result;<br />
}<br />
}<br />
}<br />
I get an error message that says "ORA-01036: illegal variable name/number" and I can't figure out why?
Thanks in advance.

Remember the error is coming from Oracle, not from C#.
Set the commandtype to stored procedure.

Yeah, that did it, thank you.

Hi All,
When I try to enter a command in any of the modules in a MS Access database, the command turns RED. It also constantly moves the cursorn to the left leaving NO spaces.
Trying to enter a command such as DoCmd. will open the popup window and then immediately close, and the DoCmd. turns RED.
Please tell me what is causing this. The database functions properly, but entering new code is a real pain.
Thanks
Gene
