The only problem I see here - i don't know how innobase/bdb will
handle tables without primary key... i think perfomance should not be
so good as with myisam. Still there is a possibility to load all data
to myisam and then run
into an
innobase-table (about 27 columns, mostly int's and float's) with about
150.000 rows with primary key and an additional unique key. The mysqldumped
data was generated one insert per row (not dumped with --extended-inserts).

Greg,
I think mysqldump and import work for all table handlers in the same
way in MySQL. But to get the maximum performance, there are some optimizations
available.
Andreas Vierengel measured that using autocommit=0 makes the import
much faster for Innobase. You have to issue a commit after you

Try:

This does basicly what you want.
After that, it's up to Heikki to fix Innobase to do delayed creation

Hi Rick,
In my C code, I use SQL statements, but I use the mySQL C API to pass on the
SQL statements, check for errors, number of rows returned, and access the
results. I would assume that this will still work; they still work with BDB
tables.
ok, it should work like for BDB. There may be
Rick,
Everything you wrote sounds good, except for one thing. I use the result
count from a select or delete for logical branching within my code. I.e. I
perform a select and if rowcount is zero, then I can do an update. That is
a problem.
Any thoughts?

You have to shut down the database, make sure that it shuts down without
errors, and then copy the Innobase data files to a safe place (it

Since Innobase is multiversioned, you will get consistent
