SELECT

Synopsis

SELECT [ * | expression [ [ AS ] expression_alias ] [, ...] ]
FROM table_name [ [ AS ] table_alias ]
[WHERE condition]

Description

The SELECT command retrieves rows from a table. A row is a sequence of expressions defined after the SELECT keyword. Expressions may have optional aliases.

table_name refers to a single IMap data structure. A table may have an optional alias.

An optional WHERE clause defines a condition, that is any expression that evaluates to a result of type boolean. Any row that doesn’t satisfy the condition is eliminated from the result.

The following features are not supported and are planned for future releases: ORDER BY, LIMIT/OFFSET, GROUP BY/HAVING, JOIN, set operators (UNION, INTERSECT, MINUS), subqueries.
