ALTER data type for all tables in db MySQL

Question

I want to convert all DATETIME columns in my db to DATETIME(6). Is there one command that I can I use to do this? I have a lot of tables and curious if there is a quick method.

Something that would do this logic

FOR T IN TABLES ALTER TABLE T MODIFY ALL DATETIME TO DATETIME(6)

Answer 1

if u are using my sql server, u can use an undocumented stored procedure to do this

EXEC ms_foreachtable 'ALTER TABLE [?] .....'

Replace table name with ? in statement
