We add an auto_increment BIGINT to every table we create. This gives us the
essence and utility of ROWID (BTW we always name the first column in a new
table 'row_id').
Just my 2 cents

I have a table that gets appended to every night with the LOAD DATA command.
The column 'start' is a unix timestamp. So when the LOAD DATA is done I then

I tried
mysql select * from database where field regexp
(\d{2,5}-\d{2}-d{1}d{1});
others:
*-*-*
??-??-?
???-??-?
(\d{2,5})?- etc, seems not working
because '-' is understood as from - to e.g a-z, 0-9, etc.,
Escape the '-' with a backslash: '\-'

Sounds like there is a misunderstanding about what exactly a data type can
do. What you can't do is change the 'type' of a column with an UPDATE

You should be able to specify 255 as the PRI KEY length... I think.
