SQL: LEFT JOIN tables

Today, I found a need to show all rows in a table and add associated information from another table. After reading a SQL reference manual on LEFT JOIN, I gave it a try and it met my needs. Here is the general format: SELECT field1, field2 FROM table1 LEFT JOIN table2 ON condition1 WHERE condition2 According to the documentation, the ON condition tells the database how to join the tables while the WHERE condition tells the database to return what row(s) as part of result set.
