Is there a fast way of getting all column names from all tables in MySQL  without having to list all the tables

I wrote this silly thing a long time ago and still actually use it now and then:

https://gist.github.com/kphretiq/e2f924416a326895233d

Basically, it does a "SHOW TABLES", then a "DESCRIBE " on each table, then spits it out as markdown.

Just edit below the "if name" and go. You'll need to have pymysql installed.

On the offchance that it s useful to anyone else  this will give you a comma-delimited list of the columns in each table   SELECT table name GROUP CONCAT column name ORDER BY ordinal position  FROM information schema columns WHERE table schema   DATABASE   GROUP BY table name ORDER BY table name   Note   When using tables with a high number of columns and or with long field names  be aware of the group concat max len limit  which can cause the data to get truncated

Similar to the answer posted by  suganya this doesn t directly answer the question but is a quicker alternative for a single table   DESCRIBE column name
