NOy vs NOx vs NOz vs NO2 vs NO

Chemists and their notations. Here's to hoping the definitions I found are used across the board.

NOx - Sum of NO and NO2
NOy - Sum of NOx and other reactive nitrogen compounds
NOz - NOy - NOx

Copy data from 1 table to another

Upon getting rid of the Institution lookup field in favor of a simple text field, I wanted to migrate the existing Institutions to the new field prior to deleting the old. Here is the syntax to update a database table field with values drawn from another field in the same statement:


UPDATE drupal_content_type_housing_application
LEFT JOIN drupal_node
ON drupal_content_type_housing_application.field_housing_inst_affil_nid=drupal_node.nid

SET drupal_content_type_housing_application.field_app_inst_affil_value = drupal_node.title

WHERE drupal_node.nid=drupal_content_type_housing_application.field_housing_inst_affil_nid
