MySQL Show Datadictionary of tables

Question

I\'d like to show DataDictionary for entire tables in database.

SHOW COLUMNS
FROM `MyDataBase`.`MyTables` 
WHERE IN ( SELECT TABLE_NAME 
           FROM info         


        

Answer 1

Usually I prefer to take this with multiple DESC. I feel SHOW COLUMNS is bit slower than DESC table_name.

So if want to get all the columns in some databases

1. Loop thru SHOW TABLES FROM DB_NAME
2. Loop thru all tables as DESC table_name

In the same way, SHOW INDEXES is slower when compared to SHOW CREATE TABLE if you just want to see the indexes on a table
