I have a database that I need to change all the columns that are in FLOAT AND DOUBLE to DECIMAL, are about 150 tables and I spend a lot of time looking one by one, there is some command that shows me this?

MY SQL Database, use Workbench 6.3

Thank you.

Existed, you will need to do a search for your tables in the database with the name of the tables you will have to take a course to go through all the tables one by one and check if there is the column you want. Look at that answer

Great, I found what I needed :D

Follows the code:

SELECT 
    *
FROM
    information_schema.COLUMNS
WHERE
    1 = 1
        AND TABLE_SCHEMA = 'nome_do_meu_banco_de_dados'
        AND (DATA_TYPE = 'FLOAT'
        OR DATA_TYPE = 'DOUBLE')

Thank you.
