SQL queries that start with the SELECT keyword and are often referred to as "SELECT statements". Teiid 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.
