[FIXED] What is SQL's Keyword order? (Postgresql)

Issue

Depending on where you put SELECT, FROM, WHERE, etc, I have run into syntax errors. What is the proper order to write queries and code? An example below:

//No error
SELECT count(*)
FROM us_counties_pop_est_2019
WHERE births_2019 - deaths_2019 <=0;

vs

//Syntax error
SELECT count(*) 
WHERE births_2019 - deaths_2019 <=0
FROM us_counties_pop_est_2019;

Solution

The main clauses of a SELECT statement in PostgreSQL are written in the following order:

• [WITH]
• SELECT
• FROM
• JOIN
• WHERE
• GROUP BY
• HAVING
• WINDOW
• ORDER BY
• OFFSET
• LIMIT

If the query includes CTEs, then the WITH clause comes before the other ones.
