MySQL

MySQL can have quite messy output when running queries from the mysql cli. You can terminate a statement with \G instead of ; to format as a list instead of table.

SELECT * FROM users\G

Alternatively, you can set the pager to less which retains the table format and can be scrolled with arrowkeys.

pager less -SFX
SELECT * FROM users;
nopager; -- to turn off

CREATE USER 'kalenpw'@'localhost' IDENTIFIED BY 'p@ssword';

replace *.* with schema.table if needed

GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost';

update

UPDATE employees SET email = 'user@domain.com' WHERE id = 123;

SELECT 
  a.*
FROM 
  map_ads_categories m
  JOIN ads a ON (m.ad_id = a.id)
WHERE
  m.category_id = 28;

SELECT 
  *
FROM 
  map_ads_categories m
  JOIN ads a ON (m.ad_id = a.id)
  JOIN categories c ON (m.category_id = c.id)
WHERE
  c.id = 28;

-- list number of rows in each table
SELECT table_name, TABLE_ROWS FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'TABLE_NAME' ORDER BY TABLE_ROWS DESC;
