I need to rename one of my fields in a table via a .install file. How can I to do this ?

Let us consider I have a table called "register" and field name called "fname". Now I need to change the field name "fname" to "name". How can I do this using a .install file?

We can add a field for a table using the below syntax :

db_add_field($ret, 'table_name', 'field_name', array('type' => 'varchar',
             'length' => 255, 'not null' => TRUE,));

What is the syntax for doing a field rename?

Using db_change_field.

Under the parameter section:

$field Name of the field to change.

$field_new New name for the field (set to the same as $field if you don't want to change the name).
