Handle DBlib error

[tcheungcm]

I used Sybase DBlib to connect to a sybase erver and then use dbuse to change database. However, it displayed STDERR on the command prompt. Instead, I would like to capture the error and suppress them. Could you advise how to do?

sub generate_syboutput{
   my $curr_dbserver=$_[0];
   my $curr_db=$_[1];
   $curr_db=~ s/\s//g;
   my $dbuser=$_[2];
   my $dbpasswd=$_[3];
   my $sp_name=$_[4];
   my $fh=$_[5];
   my $sqlcmd;
   my $dbh1=Sybase::DBlib->new($dbuser, $dbpasswd, $curr_dbserver);
   if (!$dbh1) {
      print "Connection Failed\n";
      exit(0);
   }
   print "Debug Before dbuse\n";
   if (!$dbh1->dbuse($curr_db)) {
      print "Debug this db cannot use\n";
   }
}

Output

Debug Before dbuse

Msg 10351, Level 14, State 1

Server 'MUTRDP3', Line 1

Server user id 2038 is not a valid user in database 'TestDB1'

DB-Library error: General SQL Server error: Check messages from the SQL Server.

Debug this db cannot use

I noticed there is dberrhandle or dbmsghandle that can be used for error handle but i don't know how to use it. please advice. do you have any example?

It seems that the question you have has already been asked before. Look at this thread: Error Handeling in Sybase::Dblib. Especially this excellent reply by mpeppler, where he explains how to create a message handler subroutinne and then install it using:

dbmsghandle(\&message_handler);

Which should be exactly what you are looking for. Good luck!
