how best to remove fields from a table to several terabytes using mysql. alter table will not cope ...
- It is better not to delete, all for a long time. But if it is rested - it is better to copy what should be left in the new table. - Akina
- No, I’ll have to delete, I can’t use alter table to delete the fields I don’t need ... - simpleA
- Well then CREATE - INSERT .. SELECT - DROP - RENAME. - Akina
- this is not an option ... my goal is neither to create, nor to insert, nor to delete completely, nor to rename ... but to remove some of the fields, to save disk space - simpleA
- I can not do as I want, and I do not want as I can ... well, then sit down and look. - Akina
