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.
