Oracle SELECT UNIQUE * FROM TABLE

Question

It is acceptable in Oracle databases the command

  "SELECT UNIQUE * FROM table"?

Or do I have to select the column name for that command to work?

Answer 1

您可以使用以下查询

select distinct * from table

Answer 2

Yes, this syntax is acceptable.
See this SQLFiddle example .

Answer 3

You can not use UNIQUE (or DISTINCT) if your table has LOB fields. See example: http://sqlfiddle.com/#!4/97d3e/1
