in reply to Perl on Oracle

Here is a sample script I had sitting in my temp directory -- maybe it will help a bit. (Just make sure to enter "real" values for the constants ORAUSER, ORAPASS, and ORATNS.)

#!/usr/bin/perl -w use strict; #-- Use modules use DBD::Oracle; use DBI; #-- Define local constants use constant TRUE => 1; use constant FALSE => 0; use constant ORAUSER => 'my_ora_user'; use constant ORAPASS => 'secret_password'; use constant ORATNS => 'ora_db_tns_name'; #-- Define local variables my $gDBHandle; my $gSQLCmd; my $gSQLHandle; my @gFields; #-- Initialize local variables $gSQLCmd = 'SELECT column_name, ' . ' nullable, ' . ' data_type, ' . ' data_length ' . ' FROM dba_tab_columns ' . ' WHERE owner = ? ' . ' AND table_name = ? ' . ' ORDER BY column_id '; #-- Connect to the database $gDBHandle = DBI->connect ( 'dbi:Oracle:' . ORATNS, ORAUSER, ORAPASS, { AutoCommit => FALSE, PrintError => FALSE, RaiseError => FALSE, } ) || die 'Could not connect to Oracle ['.$DBI::errstr.' - '.$DBI::er +r.']'; #-- Get the data $gSQLHandle = $gDBHandle->prepare($gSQLCmd) || die 'Error with SQL statement ['.$DBI::errstr.' - '.$DBI::err.']' +; $gSQLHandle->execute('SYS','DBA_TABLES') || die 'Error with SQL statement ['.$DBI::errstr.' - '.$DBI::err.']' +; while (@gFields = $gSQLHandle->fetchrow_array) { print $gFields[0],"\t",$gFields[1],"\t",$gFields[2],"\t",$gFields[3] +,"\n"; } #-- Close the database connection $gDBHandle->disconnect(); #-- Exit exit; #-- End of Example

[Corion]: I hope all is well marto! ;) My godson had a surprise visit to the hospital yesterday because he fell and had cut his skin besides his eye, but everything was glued together again and all is well
[marto]: good grief, that's not fun, glad to hear all is as well as could be :)
[Corion]: marto: Yeah - their mother picked all three of them up at the kindergarden to then go to the hospital, and all three of them were well behaved, and all also were quite obedient when they came home, so they recognized the situation
