Examples of Derived Column Names
•
These two examples show how to use names for derived columns.
The first example shows (EXPR) as the column heading of the SELECT result table:
SELECT AVG (salary)
FROM persnl.employee;
(EXPR)
----------------
--- 1 row(s) selected.
The second example shows AVERAGE SALARY as the column heading:
SELECT AVG (salary) AS "AVERAGE SALARY"
FROM persnl.employee;
"AVERAGE SALARY"
----------------
--- 1 row(s) selected.
Column Default Settings
You can define specific default settings for columns when the table is created. The CREATE
TABLE statement defines the default settings for columns within tables. The default setting for
a column is the value inserted in a row when an INSERT statement omits a value for a particular
column.
