A select_item specifies one or more items to be included in the results. A column is generated for every select_item passed. Each select_item consists of an arithmetic_expression. You can also pass the optional AS keyword to specify the optional sql_string or sql_name to be given to the column. (Passing the optional sql_string or sql_name without the AS keyword has the same effect).
Here is an example which creates a column named Movie_Year containing movies released in the year 2000 or more recently:
ARRAY INTEGER(aMovieYear;0)
Begin SQL
SELECT Year_of_Movie AS Movie_Year
FROM MOVIES
WHERE Movie_Year >= 2000
ORDER BY 1
INTO :aMovieYear;
End SQL
