on_insert

Specifies that the rule fires on the insertion of a row in the specified table.

Syntax:

on_insert(table){ . . . }

table: Specifies the table in the database to watch for insertions.

Remarks:

Unlike the other On prefixes, on_insert takes a single parameter that must be a table name.

Example

    // Rule 1: Whenever a name is inserted,
    // insert a new greeting into the greetings table.
    on_insert(names)
    {
        // Form the greeting using the name.
        string new_greeting = "Hello " + string(names.name) + "!";

        // Insert the greeting.
        gaia::hello::greetings_t::insert_row(new_greeting.c_str());
    }
