function dbtng_example_install in Examples for Developers 7

Same name and namespace in other branches

1. 8 dbtng_example/dbtng_example.install \dbtng_example_install()
2. 3.x modules/dbtng_example/dbtng_example.install \dbtng_example_install()

Implements hook_install().

In Drupal 7, there is no need to install schema using this hook, the schema is already installed before this hook is called.

We will create a default entry in the database.

Outside of the .install file we would use drupal_write_record() to populate the database, but it cannot be used here, so we'll use db_insert().
