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
- column_name
- | [DISTINCT] column_name
- | [DISTINCT](column_name)
- ...
where:
- DISTINCT
- Eliminates duplicate rows from the result set.
