Distinct

Distinction is critical if you want to stand out from the crowd

Description

Select all matching rows from the table references after removing duplicates in results. (Databricks SQL Language Reference SELECT)

DISTINCT eliminates duplicate values from the result set. (Snowflake SQL Language Reference SELECT)

Syntax

SELECT [ DISTINCT ] { named_expression | star_clause } [, ...]
  FROM table_reference
SELECT [ DISTINCT ]
       {
         [{<object_name>|<alias>}.]<col_name>
         | [{<object_name>|<alias>}.]$<col_position>
         | <expr>
       }
       [ [ AS ] <col_alias> ]
       [ , ... ]
[ ... ]

Sample Source Patterns
