/**
* Creates a subquery that defines a temporary named result set as a CTE.
*
* It is useful for breaking down complex queries into simpler parts and for reusing the result set in subsequent parts of the query.
*
* See docs: {@link https://orm.drizzle.team/docs/select#with-clause}
*
* @param alias The alias for the subquery.
*
* Failure to provide an alias will result in a DrizzleTypeError, preventing the subquery from being referenced in other queries.
*
* @example
*
* ```ts
* // Create a subquery with alias 'sq' and use it in the select query
* const sq = db.$with('sq').as(db.select().from(users).where(eq(users.id, 42)));
*
* const result = await db.with(sq).select().from(sq);
* ```
*
* To select arbitrary SQL values as fields in a CTE and reference them in other CTEs or in the main query, you need to add aliases to them:
*
* ```ts
* // Select an arbitrary SQL value as a field in a CTE and reference it in the main query
* const sq = db.$with('sq').as(db.select({
* name: sql<string>`upper(${users.name})`.as('name'),
* })
* .from(users));
*
* const result = await db.with(sq).select({ name: sq.name }).from(sq);
* ```
