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...

hotswaprc
HOTSWAPRC(5) File Formats Manual HOTSWAPRC(5)
NAME
hotswaprc - configuration file for hotswap
DESCRIPTION
/etc/hotswaprc is the global configuration file for the hotswap utility.
It allows system administrators to specify arbitrary shell scripts to be run after a device is inserted, as well as before and after it is
removed. Scripts are selected according to the model name retrieved from the device. This is particularly helpful for automatic configura-
tion of CD-RW drives, which require SCSI emulation and bypass normal access via the IDE subsystem.
hotswaprc is implemented as an Extensible Mark-up Language (XML) application. XML documents are structured using elements of the form
<tag-name> content <tag-name>. A Document Type Definition (DTD) describes the possible content of each element.
Please refer to the XML specification for more information. The hotswap distribution also contains an example file, doc/hotswaprc.example,
which includes the DTD for the configuration file format.
ELEMENTS
<hotswap>
This is the root element of the document. Each valid hotswaprc must contain exactly one <hotswap> element. The <hotswap> element may
contain an arbitrary number of <device> elements.
<device>
The configuration file contains one <device> element for every device for which scripts are defined. The <device> element is com-
posed of the following elements in this order: <name>, <post-insert>, <pre-remove>, <post-remove>. All but <name> are optional.
<name> The content of this element is the model identification string of the IDE device the current <device> element refers to.
<post-insert>
Contains the shell script that is to be executed after the device has been inserted and registered with the kernel.
<pre-remove>
Contains the shell script that is to be run before hotswap attempts to unregister the device.
<post-remove>
Contains the shell script that is to be run after the device had been unregistered.
