How to pipe multiline string to isql?

Using Bash shell you may use the following construct:

{
echo "DROP VIEW v1;"
echo "CREATE VIEW..."
} | isql -user SYSDBA -pass masterkey srv:db

each echo statement outputs newline at the end.

Because that's a lot of writing, use the so called 'document here' feature of the shell:

cat <<- _END_ | isql user SYSDBA -pass masterkey srv:db
DROP VIEW v1;
CREATE VIEW ...
...
_END_
