Answer 1

1. Get your shebang right
Find where your favoured shell is, using this command:
whereis bash
or
whereis sh
Then, insert a new line at the top of your sql.sh script that says
#!<FULL PATH TO SHELL>
An example of the above would be:
#!/bin/bash
2. Get your PATH right
Find where sqlplus is installed on your system, with
whereis sqlplus
Add a new second line in your script that says
export PATH=${PATH}:<SQLPLUS DIRECTORY ONLY>
An example would be
export PATH=${PATH}:/usr/local/bin # Note the word `sqlplus` is omitted - we only specify the directory where it lives
3. Make your script executable
Make your sql.sh script executable with
chmod +x sql.sh
4. Test your script outside cron
Test your script with
./sql.sh
and make sure it works prior to continuing.
5. Get the path to your script correct in cron
Find your login directory with
cd
pwd
Change your crontab script so it says:
*/1 * * * * <LOGIN DIRECTORY>/sql.sh
