Hi,
cQuery := "select name from customer" return an array with only "name" field
cQuery := "select * from customer" return an array with all fields
See here:

With SQL database you must know use command SELECT

SQL is beautifuly language, only four command SELECT, INSERT, UPDATE, DELETE (data manipulation language)
other is DDL (data definition language) like CREATE, INDEX, RENAME,...
