[NOT] IN and ANY subqueries nested within another expression are not supported if any of the column values are NULL. In the following statement, for example, if column x from either table t1 or t2 contains a NULL value, Vertica returns a run-time error: => SELECT * FROM t1 WHERE (x IN (SELECT x FROM t2)) IS FALSE;
A SELECT statement can appear almost anywhere a table expression can. Such a "nested SELECT" is often called a "derived table". Apart from many convenience methods accepting org.jooq.Select objects directly, a SELECT statement can always be transformed into a org.jooq.Table object using the asTable() method.
In this example, SELECT * FROM t1 is the outer query (or outer statement), and (SELECT column1 FROM t2) is the subquery. We say that the subquery is nested within the outer query, and in fact it is possible to nest subqueries within other subqueries, to a considerable depth. A subquery must always appear within

SQL Subquery. Subquery or Inner query or Nested query is a query in a query. SQL subquery is usually added in the WHERE Clause of the SQL statement. Most of the time, a subquery is used when you know how to search for a value using a SELECT statement, but do not know the exact value in the database. Subqueries
Nested Queries with Correlation. In the example of Nested queries, we saw how you could insert subqueries into FROM,. WHERE, AND HAVING clauses. Correlation allows the ability to allow the inner query to use the row being examined in the outer query. Let's look at the following: mysql> Select * from Class;.
