SELECT STATEMENT

In a select statement, you designate one more columns, separated by commas, and a table to get the data from, plus additional options:

SELECT
column_expr (, column_expr)*
FROM table_reference
[WHERE where_clause]
[GROUP BY group_clause]
[ORDER BY order_clause]
[LIMIT limit_clause]

column_expr

There are several ways to specify columns:

|column_name
| [DISTINCT] column_name
| [DISTINCT](column_name)
...

where:

DISTINCT
Eliminates duplicate rows from the result set.
