Mastering phpMyAdmin 3.3.x for Effective MySQL Management
When developing an application, requirements about the data structure often change because of new or modified needs. Developers must accommodate these changes through judicious table structure editing. This section explores the subject of changing the structure of tables. Specifically, it shows how to add a column to an existing table and how to edit the attributes of a column. We then build on these notions to introduce more specialized column types, and to explain their handling through phpMyAdmin. Finally, we cover the topic of index management.
Suppose that we need a new field to store a book's language and, by default, the books on which we keep data are written in English. We can call the field language, which will contain code composed of two characters (en by default).
In the Structure subpage of the Table view for the book table, we can find the Add field dialog. Here, we specify how many new fields we want, and where they will go.
