I've an MFC application which uses SQL connection using Namedpipes. I'm getting crash in the application log as follows.
Fault address: 7331293E 01:0000193E C:\bin\DBNMPNTW.DLL
Call stack:
Address Frame
7331293E 013D68DC ConnectionTransact+1AE
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

Hi,
Just use UPPER & LOWER method during insert command in sql...
|
|
|
|
|
that is fine but it will be static in either small or block letters.
I want in, whatever user enter in small or block letter.
should not be changed internally.
thanks to give me response.

Just insert teh values as suppplied, then when you are looking for them use
select *<br />
from table<br />
where convert(varbinary,username) = convert(varbinary,@inputvalue)
Using varbinary effectively makes the select case sensitive

Change collation to something case sensitive if you want to have case sensitivity.

Can I ask if this is correct.
Wince 5.0 has SQL3.0 (or SQL3.1 with the sp1) ?
What do you do for Wince 6.0? while using VS2005?
I had SQL3.0 working after the same old problem that everyone else has had with the P/invoke error. (VS2005 didn't copy the cabs into the correct directory - Deploy error) also sqlceme30.dll wasn't in the windows directory.
Fixed....
No problemss...
Yeah right, I got a new machine with wince6.0 on it.
Back to square one!
Now, it doesn't matter what I do, the same error keeps comming up 'P/invoke cant find sqlceme30.dll'.
I did notice that when you manually install the .cab files (sqlce30.wce5.armv4i.cab and sqlce30.repl.wce.arm4vi.cab)they say that 'this is not the compatable software platform, do you want to continue?'
Is this an incompatability with wince6.0?
Am I meant to use sqlce3.5?
Isn't this only in VS2008?
Is there another way around this or do I have to upgrade to VS2008?
Please help 
Thanks,
Rob.

Hi
how to conver string to date not in date time format.
means
like I want to convert this string(15 may 2008) '15/05/2008' in date format.
thanks

The date is not stored in a specific date format in the database, but to do what you have asked:
select convert(varchar,convert(datetime,'15 may 2008'),103)

not like that
I want finally in date format not in string format.
thanks

Then just use a DateTime with a "00:00:00" for the time representation, because you can then just convert it to a string when you need it as shown by the previous poster.

|

that's fine but what I want see
varDate is "2008-05-09 21:24:58.407" now I want to get record as per date(2008-05-09)without time but not getting.
select *from tblName where varDate='2008-05-09'
not getting any record
I have stored date with time also.
I tried this also
select *from tblName where varDate like '%2008-05-09%'
ans:saying can not be converted string to date
You get the best out of others when you give the best of yourself.

Well try using a little logic then. It is obviously failing because you have the time included on the database.
select * from tblName where convert(datetime,convert(varchar,getdate(),103)) = convert(datetime,'05 may 2008')
