The default heading for each column is the name given to the query results when it was created. You can rename a column heading for display purposes.
To rename a column heading, use one of these options instead of the column name in a select list:
column_heading = column_name
column_name column_heading
column_name as column_heading
This provides a substitute name for the column. For example, to change pub_name to “Publisher” in the previous query, type any of the following statements:
select Publisher = pub_name, pub_id from publishers
select pub_name Publisher, pub_id from publishers
select pub_name as Publisher, pub_id from publishers
Publisher pub_id ---------------------- ------ New Age Books 0736 Binnet & Hardley 0877 Algodata Infosystems 1389 (3 rows affected)
