Display alert that says "record exists" and commit not allowed.
Hello, my case is the following:
I wrote a code to
protected void doDML (int operation, e TransactionEvent)
{
/ * Some code here * /.
}
if(retvalue == 1)
{
/ * See the alert saying file already exists! »
}
else {}
super.doDML (operation, e);
}
My question is how to implement this alert so that users know that this recording did not commit in the database. Thank you.

Windows Vista security alert sending indicating virus attack and does not allow me to get security alerts. How to bypass or disable? I have another anti-spyware (Kapersky) program that manages all aspects and indicates no virus found.

The 'alert' is not from Vista. Your computer is infected by a rogue security program. It's called "thugs" because he pretended to be a good guy but is really bad. Don't pay them!

UTL_FILE. OPEN_FILE question to check if a file exists and is not empty
Hello
I'm writing a code in 3 separate files are created based on certain conditions of parameter for the call of the extract.
Say that the parameters are NULL, 'A' and 'B '.
When the Null State is passed to the call of the extract then it should create file A and B if the records are found. If this isn't the case, then create empty files.
It is possible that the setting of the extract is just 'A', then it would create a file say no zero and B with file from scratch.
Now when the extract is called with the parameter 'B' and if the file already exists and is not empty then I shouldn't touch/crash with empty folders.
Is there a simple way I can do this to check if a file exists and is not empty?
I use
OPEN_FILE
(gv_utl_file_path
lv_file_name
lv_file_handle
);
Help, please.
Thank you@OP: no need to open
