IMHO, this is perfectly fine. I would have done a few things differently

not source ~/.profile, this script inheirits your enviornment
use variables for the files
not save the results in $scriptdir

I also tend to use YYYYMMDD for dates, so that ls sorting by filename works better.

Code:

#!/bin/ksh
# Unix Shell Script Structure for PL/SQL queries with SQL*Plus

scriptdir=/opt/ora/scripts
queryname=example
savedir=/opt/ora/out
outfile=${savedir}/${queryname}.out
csvfile=${savedir}/${queryname}.csv
sender_mailbox=examplemailbox@example.com

mark=$(date + ' +%Y%m%d')
SQL1 ()
{
sqlplus -S <<EOF / >> ${outfile}

set echo Off
set term On
set pages 0
set head off
set ver off
set feed off
set trims on
set linesize 8000

SELECT SYSDATE FROM DUAL;

exit
EOF
}

rotate_output  ()
{
    cp "${outfile}" "${outfile}.${mark}"
}

gen_header ()
{
    echo "field1;field2;field3;field4" > "${outfile}""
}

mail ()
{
    (
        cat $scriptdir/MSG.txt
        uuencode "${outfile}""${csvfile}"
    ) | mailx -s "" -r "${sender_mailbox}"
}

gen_header && SQL1 && rotate_output && mail
