# pgsql_templates

[![License][license-pic]][license-url]

A collection of `sql` scripts for `PostgreSQL` database.

Includes migration script which populates db with fake data: 10000 user entities and 100 posts per user.

There is fake person data used only.

During user creation random names are taken from [main.random_name()](./create/function/random_name.sql) function

and user `last_name` is a random string (mixed upper and lower cases) generated by [main.random_chars()](./create/function/random_chars.sql).

All values can be customized by adjusting `sql` scripts.

## Fake db usage

> **Note**

>

> For running migrations [docker-compose](https://docs.docker.com/compose/install/) is required to be installed.

1. Open terminal and run `docker-compose up` to see all outputs or `docker-compose up -d` with daemon mode.

2. Wait for a wile until migration is completed (you can check logs by running `docker logs -f pg_migration`).

3. Connect to `PostgreSQL` ([using default credentials](./docker-compose.yml)) with any client ([cli](https://wiki.postgresql.org/wiki/PostgreSQL_Clients#CLI_Clients), [gui](https://wiki.postgresql.org/wiki/PostgreSQL_Clients#Cross-platform_GUI_Clients), [web](https://wiki.postgresql.org/wiki/PostgreSQL_Clients#Web_Clients)) and try to query for `user` or `post`:

```sql

SELECT u.name, u.last_name FROM main.user AS u LIMIT 10;

SELECT p.user_id, p.title FROM main.post AS p LIMIT 10;

SELECT

  u.id,

  u.name,

  to_jsonb(array_agg(p.title))

FROM

  main.user AS u

  JOIN main.post AS p

    ON p.user_id = u.id

GROUP BY

  u.id

LIMIT

  10;

```
