SELECT Clause

SQL queries that start with the SELECT keyword are often referred to as SELECT statements. The CData Virtuality Server supports most of the standard SQL query constructs.

Usage

SELECT [DISTINCT|ALL] ((expression [[AS] name])|(group identifier.STAR))*|STAR ...

Syntax Rules

• Aliased expressions are only used as the output column names and in the ORDER BY clause. They cannot be used in other clauses of the query;
• DISTINCT may only be specified if the SELECT symbols are comparable.
