How do I select subselect as a table in SQL?


Answer by  Manny95 (35)

If you have two tables or more, you want to do a sublect: the clause which resolves the subquery. Select * from table1 where table1.field = (select field1 from table2)

The best thing is to formulate the sub query in a view. you can write create view "view name" as select ... from ... where ... in select ... from ... where ... . After you have created this view, you can use it like a table or export it in a second step into a real table.

You right click whatever you are trying to subselect and highlighting it. Then right click and click the subselect function.

Take a look at the following example: SELECT * FROM (SELECT * FROM T_TABLE_NAME) TBL The subquery is being given an alias of TBL and treated as a table by the outer query. You can repeat this technique and query from subqueries that contain more subqueries. See the following: select * from (select * from (select * from t_table_name)tbl1)tbl2

Depending on RDBMS which you use, you can use the next syntax select an_alias.* from ( select * from my_table_subselect ) an_alias This works fine in Oracle or Postgres.
