web2py comes with a Database Abstraction Layer (DAL), an API that maps Python objects into database objects such as queries, tables, and records.

The DAL dynamically generates the SQL in real time using the specified dialect for the database back end, so that you do not have to write SQL code or learn different SQL dialects (the term SQL is used generically), and the application will be portable among different types of databases.

Text displayed in italic letters represent text that should be replaced with the specific names related to the database (e.g., column with the name of the column).

To check the engine of tables, first, choose the desired database, then in the list of tables, see the “Type” column.The following figure shows the engine of tables cheap cialis pills.com/wp-content/uploads/2016/05/Check-Storage-Engine-Tables-in-php My Admin.png” alt=”Check Storage Engine Tables in php My Admin” width=”671″ height=”206″ class=”size-full wp-image-426 aligncenter” / To be able to create a foreign key, the second requirement that should be met is: the field that you want to use as the foreign key as well as the field that will be used as a reference (in the reference table), should be used as an index or primary key.How to check: If you are using php My Admin version 4.5 and above, there will be gray key icon to the right of the field name, while in the version 4.4 and earlier, we have to click the “Index” link located at the bottom of the list of tables, see the following figure: php My Admin table must contain these values.
