In the "information_schema" database, which you can use to access schema
information, MySQL differs between "CHARACTER_MAXIMUM_LENGTH" (the
number of characters) and "CHARACTER_OCTET_LENGTH" (number of bytes).
But this need not be the same factor for all columns:
If you specify one with "charset latin1", it is one octet (byte) per
So I don't see any use in such a constant factor.
And sorry, no, off-hand I don't know a way to programmatically ask the
server for this factor.
If you need to know the number of characters specified for some column,
you should access the "information_schema" database and get all those
details, including character set and collation.
