Well, if you have other varchar fields in your table, then it probably
wouldn't have any impact on performance. But since BLOBS and TEXT are
considered varchar, the table no longer is a fixed width. It is my
understanding that MySQL can locate specific records faster (even with
indexes) in tables with fixed widths (i.e., no variable-length columns).

Subject: generic question re. image blobs in dbs
Hi!
There is a consensus that blobs containing image files like .jpgs, .gifs,
etc. might better be stored just as links in the database, with the
actual
files in a directory pointed to by the database links. Forgive my
ignorance, but can someone explain a few of the more obvious reasons why
this makes a difference? For example, if I avoid SELECT * when referring
to a table with blobs it seems to be pretty fast. . .So I'd only refer
to the heavyweight column when absolutely necessary. Does it take a lot
longer to pull out the blob than it would to load the file contents into a
browser?
Thanks for any information you can impart!
Cheers!
