+# 10 Ways to Become a Better RedwoodJS Developer
+
+1. How to Ask Questions
+
+1. Postgres and General Data Design
+
+   - [Prisma's Data Guide](https://www.prisma.io/dataguide)
+     Learn how databases work, how to choose the right one, and how to use databases with your applications to their full potential
+   - [About PostgreSQL](https://www.prisma.io/dataguide#postgresql)
+
+1. Postgres CTEs & Window Functions
+
+   ### Window Functions
+
+   - Window functions provide the ability to perform calculations across sets of rows that are related to the current query row
+   - https://www.postgresql.org/docs/15/functions-window.html
+   - `row_number()`
+   - `dense_rank()`
+   - `ntile()`
+   - `lag()`
+   - `lead()`
+   - the `OVER` clause
+   - the `PARTITION BY` [list](https://www.postgresql.org/docs/15/sql-expressions.html#SYNTAX-WINDOW-FUNCTIONS)
+
+   ### Example
+
+   ```ts
+   /**
+    * Calculates the leaders for a leaderboard based on the number of plays,
+    * the total correct, incorrect, and unanswered.
+    *
+    * Uses a CTE and a Postgres DENSE_RANK() window function to ranking each players place
+    *
+    * Dense ranking gives the player with teh same score, the same rank (ie, share place)
+    *
+    * The top player is the one with the most correct plays.
+    *
+    * I *really* wish Prisma supported views.
+    *
+    * @returns an array of <Leaderboard>
+    * @see Postgres Window Functions https://www.postgresql.org/docs/current/functions-window.html
+    */
+   export const leaderboards = async () => {
+     // how can I import the Leaderboard type for the graphql types (not Prisma types)?
+     const leaders = await db.$queryRaw<typeof Leaderboard[]>`
+   WITH correct_counts AS (
+       SELECT
+       p. "playerId",
+       1 AS played,
+       CASE WHEN correctness = TRUE THEN
+           1
+       END AS correct,
+       CASE WHEN correctness = FALSE THEN
+           1
+       END AS incorrect,
+       CASE WHEN correctness IS NULL THEN
+           1
+       END AS unanswered
+       FROM
+       "Play" p
+   ),
+   totals AS (
+       SELECT
+       "playerId",
+       coalesce(sum(played),
+           0) AS "playedTotal",

+           0) AS "correctTotal",
+       coalesce(sum(incorrect),
+           0) AS "incorrectTotal",
+       coalesce(sum(unanswered),
+           0) AS "unansweredTotal"
+       FROM
+       correct_counts
+       GROUP BY
+       "playerId"
+   )
+   SELECT
+       t. "playerId",
+       p.name,
+       p. "gravatarHash",
+       t. "playedTotal",
+       t. "correctTotal",
+       t. "incorrectTotal",
+       t. "unansweredTotal",
+       DENSE_RANK() OVER (ORDER BY t. "correctTotal" DESC) AS place,
+           ROW_NUMBER() OVER () AS "leaderboardRowNumber"
+       FROM
+       totals t
+       JOIN "Player" p ON p.id = t. "playerId"
+       ORDER BY
+       "leaderboardRowNumber" ASC,
+       place DESC,
+       p.name ASC`;
