Using a subquery in 'FROM' in gorm

Question

I would like to know how I can use a subquery in FROM clause using gorm. It would look like the following:

SELECT * FROM 
(
  SELECT foo.*
  FROM foo
  WHERE bar         


        

Answer 1

FYI – Jinzhu's method doesn't work

I have subqueries working using this method...

var somevalue = 1
row := db.Select("something").Table("first_table").Where("exists(?)", db.Select("a_relationship_to_something").Model(&SecondTable{}).Where("id = ?", somevalue).QueryExpr()).Row()
var result string
row.Scan(&result)

I've tested this with row(), rows(), first(), and find(). You can also use both .Table() and .Model() interchangeably as shown in the example.
