Úteis Métricas/Estatísticas

[hhlp]

Li em algum lugar aqui no Discourse, mas agora não consigo encontrar: um post onde alguém escreveu uma métrica ou estatística útil usando uma consulta SQL… Existem algumas que eu gostaria de usar.

Poderia me indicar?

Atenciosamente.

There are a couple of topics that relate to this:

1. Data explorer queries

(Superseded) What cool data explorer queries have you come up with?

This topic became too long to be easily searched and has been broken down into separate topics. If you have any questions about how to write a Data Explorer query, or have one to share, please start a new topic in the data & reporting category and tag it with the sql-query tag. For an alternative searchable list of queries that were in this topic, see @SidV’s query list on GitHub.

2. Badge queries

[Superseded] What cool badge queries have you come up with?

Enabling Badge SQL entails security and performance risks so it is not available by default. For more information, see: Enable Badge SQL This topic became too long to be easily searched and has been broken down into separate topics. If you have any questions about how to write a badge query, or have one to share, please start a new topic in the data & reporting category and tag it with the sql-triggered-badge tag.

It is possible to enter the ruby console and run ActiveRecord queries, if you feel more comfortable doing that.

But IMHO, the best way is to use the Data Explorer plugin.

• it provides information about tables, fields, and field datatypes
• it does only SELECT queries so it is inherently safer because it can not do anything destructive
• has built in LIMIT so a poorly crafted query will not bog or crash your site

Some knowledge of the database architecture is still needed, especially for complex queries. But many (IMHO, most) times it is intuitive. eg.
it is clear that the posts table’s posts.topic_id field references the topics table’s topics.id field.
