Where to store SQL commands for execution

Question

We face code quality issues because of inline mysql queries. Having self-written mysql queries really clutters the code and also increases code base etc.

I'm late to the party, but if you want to store related queries in a single file, YAML is a good fit because it handles arbitrary whitespace better than pretty much any other data serialization format, and it has some other nice features like comments:

someQuery: |-
  SELECT *
   ,DATE_ADD(sc.created_at,INTERVAL 14 DAY) AS duedate
   ,distance_mail(?,?,lat,lon) as distance,count(pks.skill_id) c1
   ,count(ps.profile_id) c2
    FROM TABLE sc
    -- ...

# Here's a comment explaining the following query
someOtherQuery: |-
  SELECT 1;

This way, using a module like js-yaml you can easily load all of the queries into an object at startup and access each by a sensible name:

const fs = require('fs');
const jsyaml = require('js-yaml');
export default jsyaml.load(fs.readFileSync('queries.yml'));

Here's a snippet of it in action (using a template string instead of a file):

const yml =
`someQuery: |-
  SELECT *
    FROM TABLE sc;
someOtherQuery: |-
  SELECT 1;`;

const queries = jsyaml.load(yml);
console.dir(queries);
console.log(queries.someQuery);
