Thats great. Don't worry about the table names - they were hyperthetical - trust me postng the actual query wouldnt have provoked any response it's huge.

Hi,
I have a problem with a query on a locked table.
The Database I use is mySQL and I want to get a exception when the program try's
to execute a query on a locked table. I tried to set the CommandTimeout in the
OdbcCommand-Object and I also tried to set the "innodb lock wait timeout"-Attribut
from MysQL but it doesn't work.
Has anybody an idea..?

Have you figured out the problem?

Hi,
not realy... I've found an ugly workaround but that was not what
I'm searching for. In other Database Management Systems is something
like LOCK NOWAIT.
Do you have any idea?
Thanks

I have a difficulty in putting the array in to a recordset.
Please suggest.
Thanks in advance

What difficulty are you having? Be a bit more descriptive about your problem...

I am getting the data from database as usual in to a recordset.
I am having some data in array.I want to put the data back in some form in to a recordset so that the existing functionlity does not change.
Remark: The recordset has to be disconnected and database need not be updated.
It is just the calculation that I want to do on the recordset.
Please suggest.
Thanks and regards,
Anil

Just insert the individual elements of the array into the record set. The recordset class should have an Add method to allow you to add the new data into the recordset. I hope this sheds some light for you.

In my case I want to get all rows from a table (however it could be the case I [or someone else] only want to get a specific few). How would I count how many rows have been effected by the SQL query?
Heres a bit of my code:
private const string sqlGetAll =
"SELECT ID , Name , PortalMarkupFile AS Portal " +
"FROM Swin_Devices";
command = new SqlCommand(sqlGetAll, connection);
SqlDataReader reader = command.ExecuteReader();
So I'd like something like reader.getAffectedRows or something similar?
Thanks in advance,
Pete

When you are just selecting data none of the rows get affected. Why don't you use sql Count function?
|
|
|
|
|
Quick bit of research into COUNT and using SELECT COUNT(*) worked a treat.
Thank you!

Hi All,
I need to get rid of paging. In other words, I have a webpage in which the data is now being displayed in 3 pages but I want to bring the data alll in one page. Would really appreciate if someone could give me the idea?
Thanks in advance
|
|

|

How is your paging being accomplished? Is it via a datagrid/repeater or through the database select? If it's via the datagrid, you can switch paging off by setting AllowPaging = false;
|
|
|
|
|
No idea what you are talking about.
Can you clarify please.

I am sorry but now I would try to be more clear.
I have a webpage where the results are shown in more than one page(which is called paging in CF). Now, what I want to do is to put all the results in one page. so, basically no paging.
I hope this helps.
Thanks very much

Hi
Are you using ASP.Net(C#.Net or VB.Net)? Are you using any .Net server control to display data on the webpage?
Paging can be done by setting the attribute AllowPaging to TRUE in your .Net Server control. Check your code / HTML page of your web page and change it to FALSE.
Hope this helps.

Hi All,
I have a single table that contains the following Columns
As you can see i generated the data base on ASc on id's
Select * from Call_register order by id
Table Call_Register
id Call(in Hour) Seconds
76 00:04:23 263
76 00:05:58 358
76 00:06:38 398
77 00:06:22 382
77 00:01:29 89
77 00:10:28 628
77 00:01:18 78
78 00:03:35 215
79 00:07:26 446
I want to regroup them as follows : want to also keep track of number of time id occurs:Like
id occurance call(in Hour) totalSeconds
76 3 times 00:04:23 +00:05:58+00:0638(= 263+358+398=
77 4 times 382+89+628+78=1019seconds
Could you please help in getting me the script that enables me to generate in this format
Id number of times id appeard(frequency) : sum(totalHour) sum(seconds)
76 3 times
77 4 times
78
etc..
Please advice
Thanks

Just in case you are still struggling:
select
id,
cast(count(id) as varchar(10)) + ' times' as 'Frequency',
sum(call) as 'TotalCALL', --this was int in my case
sum(seconds) as 'TotalSeconds' --this was int in my case
from Table
group by id
Cheers

Hi guys, I hope this is the right section, but as it's more of a SQL problem, it most likly is.
Anyway, my problem is that I get this error:
"DEFAULT or NULL are not allowed as explicit identity values."
Everytime I try to run my code, but of all the searhing I've done on Google and Google code search I really can't find anything amiss. I'll post my source (What I think is needed) at the bottem. If there are any important lines of code that I've left out ask and I'll promptly post them.
Dim mySelectQuery As String = "SELECT * FROM tblCallers SET IDENTITY_INSERT tblCallers ON"
Dim myInsertQuery As String = "INSERT INTO tblCallers (CallerID, Name, Address, PostalCode, City, PhoneNumber, EmailAddress) VALUES(DEFAULT, '" & Name & "', '" & Address & "', '" & PostalCode & "', '" & City & "', '" & PhoneNum & "', '" & EmailAddress & "')"
Dim myConnection As New Data.SqlClient.SqlConnection(myConnString)
Dim myCommand As New Data.SqlClient.SqlCommand(mySelectQuery, myConnection)
Dim myCommand2 As New Data.SqlClient.SqlCommand(myInsertQuery, myConnection)
Dim retvalue As Integer
myConnection.Open()
retvalue = myCommand2.ExecuteNonQuery()
Console.WriteLine(retvalue)
Dim myReader As Data.SqlClient.SqlDataReader
myReader = myCommand.ExecuteReader()
myReader.Close()
myConnection.Close()
I know that the code works because I use took it from another program I wrote and added the "SET IDENTITY_INSERT tblCallers ON" line. Also, the CallerID field is an Identity field.
Thanks,

You may wish to read about SQL Injection Attacks and how to prevent them[^] becuase your code is vulnerable right now.
My suggestion, don't include the column that will automatically receive the identity in the list of columns you are inserting.

Thanks a lot for the reply!
I know my code might be a bit shakey, but I only started learning SQL, ASP.NET 2.0, and Visual Basic .NET last week. So sorry for any newbie mistakes, heh.
Thanks for the advice about SQL Injection, I've only ever heard of it. Never read about it myself. This program will only be going up on a in-office intranet though, so I'm not too worried about attackers. But I'll probably fix it up once I read the links you posted. Never too early to start learning good programming habits.
As for not including the column which will recieve the identity, that did the trick! Thanks a lot for your help!

Statistically, most attacks are from people within the organisation.
