[libreoffice-users] Re: Base created from xlsx file - move to proper DB

I would only recommend using embedded Firebird if you're comfortable
with all of its still numerous bugs, and are happy to get your hands
dirty correcting data types, lengths, etc and possibly corrupted data.

Also, it is my understanding that there is currently still a limitation
of 64Kb for the total insert length of any transaction, meaning that you
have to be especially wary of the number, and length of any VARCHAR data
that you have in your spreadsheet.

If you have Unicode characters in any cell, you might also get an import
failure because these are coded over 4 bits per character, which can
rapidly cause the automatically created insert statement to exceed the
64KB limit, and again, fail.


My advice would be to stick to embedded HSQLDB until, or unless, you are
comfortable with such limitations.
