I've got a RedHat 8 box running MySQL 3.23.55. One of my tables has a field with 'varchar(250)' as the data type.

I think you should reconsider this from a design perspective... making a
very long field the primary key is inefficient in space (the primary key
index gets really big) and you have to specify all of those characters
when you want to find a specific record again.

I don't know whether MySQL can index BLOB fields anyway... most
DBMSs won't even allow you to try.
I 100% agree. This is actually a stopgap measure while I implement a completely new design for the database (using PostgreSQL as the RDBMS). In the meantime, though, the customer needs more space in that field; so, I oblige :^)
