"Accessing Isql command via VI editor"

Post #302975340 by RudiC on Saturday 11th of June 2016 08:27:59 AM

Let's get some terms right, as from reading your post I get the feeling not all is crystal clear to you:

df -h does not "load filesystem in OS level", it "... displays the amount of disk space available on the file system ...". A look at man df might help.

vi is one among many text editors. It does not execute scripts nor programs but allows you to create and modify text files. These, if consisting of commands and shell builtins, are known as scripts and, if having the "executable" permission set, can be executed (better: interpreted) by the shell. Just like commands.

Not having the slightest clue about isql I guess it to be an sql interpreter. You can run it interactively to perform ad hoc queries etc., or have it read and interpret sql scripts. One among others is the way you show in post#1 using a "here document".

I'd propose to prepare a shell script very similar to the one in post#1, make it executable, test it interactively, and, when happy with it, run it using su's -c option.


EDIT: Looks like my post crossed your recent update of your post...

Apache::Session::Store::Sybase(3pm)			User Contributed Perl Documentation		       Apache::Session::Store::Sybase(3pm)

NAME
Apache::Session::Store::Sybase - Store persistent data in a Sybase database SYNOPSIS
use Apache::Session::Store::Sybase; my $store = new Apache::Session::Store::MySQL; $store->insert( $ref ); $store->update( $ref ); $store->materialize( $ref ); $store->remove( $ref ); DESCRIPTION
Apache::Session::Store::Sybase fulfills the storage interface of Apache::Session. Session data is stored in a Sybase database. SCHEMA
To use this module, you will need at least these columns in a table called 'sessions': id CHAR(32) # or however long your session IDs are. a_session IMAGE To create this schema, you can execute this command using the isql or sqsh programs: CREATE TABLE sessions ( id CHAR(32) not null primary key, a_session TEXT ) go If you use some other command, ensure that there is a unique index on the id column of the table CONFIGURATION
The module must know what datasource, username, and password to use when connecting to the database. These values can be set using the options hash (see Apache::Session documentation). The options are: DataSource UserName Password Example: tie %hash, 'Apache::Session::Sybase', $id, { DataSource => 'dbi:Sybase:database=db;server=server', UserName => 'database_user', Password => 'K00l', Commit => 1, }; Instead, you may pass in an already-opened DBI handle to your database. tie %hash, 'Apache::Session::Sybase', $id, { Handle => $dbh }; Additional arguments you can pass to the backing store are: Commit - whether we should commit any changes; if you pass in an already-open database handle that has AutoCommit set to a true value, you do not need to set this. If you let Apache::Session::Store::Sybase create your database, handle, you must set this to a true value, otherwise, your changes will not be saved textsize - the value we should pass to the 'set textsize ' command that sets the max size of the IMAGE field. Default is 32K (at least in Sybase ASE 11.9.2). AUTHOR
This module was based on Apache::Session::Store::Oracle which was written by Jeffrey William Baker <jwbaker@acm.org>; it was modified by Chris Winters <chris@cwinters.com> to work with Apache::Session 1.5+ with changes from earlier version of Apache::Session::DBI::Sybase from Mark Landry <mdlandry@lincoln.midcoast.com>.
