sql joins [message #400]

When trying to display field from related table I found the sql LEFT JOIN very useful at picking description field in a LIST2 screens.
But when I try to access a related row using a part of a primary key (a relation table LIST1, used for search purpose), the LEFT JOIN statement is not working.
Any idea ? Do you have an extended set of sql statements ?

The Radicore framework can only automatically construct sql queries containing JOINs when the relevant relationship details have been entered into the data dictionary AND all the foreign key fields are present. For any other situation you will have to construct the sql query manually in your code. An example is given in http://www.tonymarston.net/php-mysql/infrastructure-faq.html #faq08
