Reg stands for "regarding" Error in the sence ---> I have a function to create a database and so on...... using libpqxx library. And i have a CLInterfacing program through which i can able to select option which i want to do. I am able to get the error messages if anything wrong i give...... But the errors are like below. Say,If i have created a database called "sample" and when i try to give the same database name to create againg it is displaying message like: Database "sample" already exists-->Postgresql format (Here the messages are Specific right) What i want to manipulate is: It should simply display Database already exists --->Format i need (The messages i need to display generally) I am able to get the error code as a return value from the function using, return (PQresultErrorField(res,PG_DIAG_SQLSTATE)); Problem is i don't know how to generalize the messages once i get this....Pls any one help me in this regard Thanks, Sandhya ----- Original Message ----- From: "Michael Fuhr" <mike@fuhr.org> To: "sandhya" <sandhyar@amiindia.co.in> Cc: "postgre" <pgsql-admin@postgresql.org> Sent: Wednesday, October 19, 2005 10:55 PM Subject: Re: [ADMIN] Reg : Error Handling > On Wed, Oct 19, 2005 at 03:56:57PM +0530, sandhya wrote: > > In error handling suppose if the database already exists.. > > > > It is returning : database "sample(say)" doesn't exists. > > What is "it"?
