Spark supports <code>SELECT</code> statement that is used to retrieve rows
from one or more tables according to the specified clauses. The full syntax
and brief description of supported clauses are explained in
[SELECT](sql-ref-syntax-qry-select.html) section. The SQL statements related
to SELECT are also included in this section. Spark also provides the
ability to generate logical and physical plan for a given query using
[EXPLAIN](sql-ref-syntax-qry-explain.html) statement.
