/**
* 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);
* ```

*
* This method allows the main query to reference a temporary named result set.
*

*
* @param queries The CTEs to incorporate into the main query.

/**
* Creates a select query.
*
* Calling this method with no arguments will select all columns from the table. Pass a selection object to specify the columns you want to select.
*
* Use `.from()` method to specify which table to select from.
*
* See docs: {@link https://orm.drizzle.team/docs/select}
*
* @param fields The selection object.
*
* @example
*
* ```ts
* // Select all columns and all rows from the 'cars' table
* const allCars: Car[] = await db.select().from(cars);
*
* // Select specific columns and all rows from the 'cars' table
* const carsIdsAndBrands: { id: number; brand: string }[] = await db.select({
* id: cars.id,
* brand: cars.brand
* })
* .from(cars);
* ```
*
* Like in SQL, you can use arbitrary expressions as selection fields, not just table columns:
*
* ```ts
* // Select specific columns along with expression and all rows from the 'cars' table
* const carsIdsAndLowerNames: { id: number; lowerBrand: string }[] = await db.select({
* id: cars.id,
* lowerBrand: sql<string>`lower(${cars.brand})`,

*
* See docs: {@link https://orm.drizzle.team/docs/select#distinct}
