Does BigQuery support the WITH clause? I don't like formatting too many subqueries.
For example:
WITH alias_1 AS (SELECT foo1 c FROM bar)
, alias_2 AS (SELECT foo2 c FROM bar a, alias_1 b WHERE b.c = a.c)
SELECT * FROM alias_2 a;

The WITH clause contains one or more common table expressions (CTEs). Each CTE binds the results of a subquery to a table name, which can be used elsewhere in the same query expression. The syntax is as follows: WITH cte[, ...] BigQuery does not materialize the results of non-recursive CTEs within the WITH clause.
BigQuery RegExp: How to replace special characters To replace special characters, you can use regular expressions like this [^a-zA-Z0-9]+ and REGEXP_REPLACE function.
BigQuery Between operatorDue to the inclusive nature of this operator, it includes both the beginning and ending values of the range. The values may be of any kind, including text, numeric, date data, etc. This operator can be used in conjunction with the SELECT, WHERE, INSERT, UPDATE, and DELETE statements.
COALESCE. Returns the value of the first non-null expression. The remaining expressions are not evaluated. An input expression can be any type.
