Hi Christian,

The problem, I believe, is with the number of parameters (parameter
markers) that crosses a certain boundary. We ran into an upper limit of
2000 (or something like that) on MSSQL server. That is a problem for us
because we sometimes generate queries that have more parameters (yes...
really), and then MSSQL server throws an exception.

So, I am very interested in your solution. It could help solve our
problem as well.

a prepared statement?

Hi Roger,

OJB uses alsways prepared statements as armin said before, but do you
have problems with the prepared statements or with the count of
parameter markers (? in the where clause)?

I am asking because we did a lot of experiments with different
implementations (or specialisations) of SqlGeneratorDefaultImpl. The
first implementation was not using parameter markers at all.
So we used prepared statements without any parameter markers, which
comes close to dynamic statements (at least in my understanding and I
think this is what you need).

I would like to post what we did to discuss it here on the mailing list
(we are using db2 and could increase the performance 40% in online acces
and 50% in batch access).
