/**

* produces an indicator variable, and the result is a relational expression
* which outer joins that indicator to the original query. After performing
* the outer join, the condition will be TRUE if the EXISTS condition holds,
* NULL otherwise.
*
* @param seek A query, for example 'select * from emp' or
* 'values (1,2,3)' or '('Foo', 34)'.
* @param subQueryType Whether sub-query is IN, EXISTS or scalar
* @param logic Whether the answer needs to be in full 3-valued logic (TRUE,
* FALSE, UNKNOWN) will be required, or whether we can accept an
* approximation (say representing UNKNOWN as FALSE)
* @param notIn Whether the operation is NOT IN
* @return join expression
