Here's a pattern to join two different GA PROPERTIES (i.e. > ANY means greater than at least one value, that is, greater than the minimum. Then the queryusing the EXISTS predicatechecks the addresses in the inner (correlated) subquery. Unless the query optimizer re-writes the correlated subquery with a join, the correlated subquery has to use a nested loop join, which means that the subquery will be executed repeatedly, once for each row that might be selected by the outer query. Items in the JOIN operation can be BigQuery tables, subqueries, WITH statements, or ARRAYs (an ordered list with zero or more values of the same data type). If the subquery returns more than one .

You can find the first part here: Part 1: Setting and Identifying Row Goals; It is relatively well-known that using TOP or a FAST n query hint can set a row goal in an execution plan (see Setting and Identifying Row Goals in Execution Plans if you need a refresher on row goals and their causes). Unsupported subquery with table in join predicate. The inner query is evaluated, producing the ID numbers of the vendors who meet the subquery qualifications. The previous example produces the same results as issuing two separate DML statements: The SELECT statement, to return a temporary table, tmp1, that contains the same rows from .
