HI,
I spent all this afternoon to solve this problem, so I thought to write
two lines to describe this strange behaviour.....
- I'm using PHP with PEAR:DB package.
- I set autocommit to false
- I prepare a statement
- I execute it
- THE PAGE NEVER COMPLETES

Hi all,
I'm trying to do an insert using MySQL OleDb Provider.
I'd like to use the prepare() method of OleDbCommand class
to precompile the statement.
The problem is that when I issue prepare() I get an error
"OleDbCommand.Prepare requires all parameters to have an explicitly set
type"
I have checked the parameters and it seems to me that I didn't forget
anything....anybody can help me ?

Hello guys
Please have a look on following paragraph from ".NET Data
Access Architecture Guide".

Although you can repeatedly use the same SqlCommand object
to execute the same command multiple times, do not reuse
the same SqlCommand object to execute different commands.
1) You do not need to explicitly open or close the
database connection. The SqlDataAdapter Fill method opens
the database connection and then closes the...

OleDbCommand.Prepare error: Size of parameter (VB.NET 2003)
I need to do a SQL INSERT statement into an Access table, and I’d like to
use the exact technique described in the Help file example for
OleDbCommand.Prepare Method.
When I follow the example exactly I get the unhandled exception error message:
“OleDbCommand.Prepare Method requires all parameters to have an explicitly
set type”.

Dear all,
I have read on article that the same SQL querry is call many time, for
perfomramce reaon it is needed to call the SQLCommand.Prepare method before
executing.
What does that prepare really do ? Is it caching somehow the whole select
statement ?
thanks for your reply

I got a silly question about Sqlcommand . In my form, there are 5 methods
which use the same sqlcommand to execute reader.
I had create and dispose for each sqlcommand in every method. Some said
that I can only delcare one sqlcommand and re-use it in every
method and no need to dispose until form closed. I am wonder which approach
is correct.

Dim cmdSearch As New SqlClient.SqlCommand

I have a c# program that loops through a table on a DB2 database.
On each iteration it assigns data to values in the SqlParameter
collection. The command text is an INSERT statement to a Sql Server
database, run with an .ExecuteQuery I enclosed the loop in a
SqlTransaction and commit it at the end.
I timed the program and it inserts about 70 records a second...which I
think is sort of slow...so I set up some Debug.WriteLines to...

I want to pass a SqlCommand object as a input parameter to a method.
I want to pass the SqlCommand "by value" so that any updates to the
original object are *not* reflected in the object within my method.
How can I do this?

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
