If you want to add rows to a table don't use SAVE TO DATABASE. You can use INSERT INTO or INSERT ALL to add rows to an existing database table. INSERT ALL is useful for inserting large numbers of rows.
Here's a simple insert example:
dbc = create database connection("YOUR-CONNECTION-STRING-GOES-HERE");
one_id = "1121121";
sql = evalinsert(
"INSERT INTO myschema.my_activity_log
(user_created, date_created, my_section, activity)
VALUES ('^one_id^', CURRENT_DATE, 'DASHBOARD', 'REFRESH')");
// Run this SQL. No table is retrieved as it's a simple insert
execute sql(dbc, sql);
// Close the database connection - end of initialization queries
Close Database Connection(dbc);
You can find more information on the INSERT ALL command (for Oracle) here: https://www.techonthenet.com/oracle/questions/insert_rows.php
