Implicit aliasing of column not allowed. Use explicit AS clause.
Example
You can set column aliases in SQL typing the identifier right after the column name.
SELECT column_one c1
FROM table;
(or) you can use the keyword AS to indicate the alias.
SELECT column_one AS c1
FROM table;
AS is a more explicit way of mentioning the alias.
