There should be a note of caution though if you are planning to use the result of your shell commands back into the second part of the SQL, similar to this:-
Code:
column="COL1"
sqlplus <<-EOSQL
$username/$password
select $column from my_table;
!column="COL2"
select $column from my_table;
EOSQL
I think that the variables in the section before the EOSQL label (called a Here document) will be evaluated by the shell before the sqlplus command is called, so you will actually still select COL1 for the second line.
I hope that this gives you something to consider. It may be that there is still a need to execute as separate queries if this is the case. The alternate would be to have a reference table in your database and then when you ! out to the shell, call another SQL to update this table before returning to the main execution. It's not pretty, but it might work.
Many things are achievable from within SQL already. What are you trying to do in the shell? It might be that we can capture it into the SQL.
