Re: how to connect to database in shell script

Hi,
If this is oracle we are talking this would be a way (there's several other ways) :

#!/bin/ksh
sql_logon=$1
sql_script=$2
$ORACLE_HOME/bin/sqlplus << !! 2>&1 >tgd008.log
$sql_logon
@$sql_script;
quit
!!

Hope this helps,
Tom Geudens

Re: how to connect to database in shell script

Hi Fiatu,

Here is what you need :

1. Remote database

#sqlplus userName/passWord@OracleInstance< /tmp/output.log 2>&1
select ....
insert ....
delete ....
update ....

EOD


The name "OracleInstance" is the name of the oracle instance defined in the file tnsnames.ora

2.Local database

#sqlplus userName/passWord< /tmp/output.log 2>&1
select ....
insert ....
delete ....
update ....

EOD

Re: how to connect to database in shell script

It's PERL time:



use strict;
use DBI;

my $dbh = DBI->connect( 'dbi:Oracle:orcl',
'jeffrey',
'jeffspassword',
{
RaiseError => 1,
AutoCommit => 0
}
) || die "Database connection not made: $DBI::errstr";

my $sql = qq{ CREATE TABLE employees ( id INTEGER NOT NULL,
name VARCHAR2(128),
title VARCHAR2(128),
phone CHAR(8)
) };
$dbh->do( $sql );

$dbh->disconnect();
