Re: Problem with Use Declare/Fetch

Hi Hiroshi,

Sorry for delay!

I sent the links to download the logs directly in your e-mail.
I analyzed the logs and I believe that the error was in this cursor:

[1168-47.972]   stmt_with_params = 'declare "P00954" cursor for SELECT
T1.Fn04CodEmp(...)

This query must return about 14k rows. But with use/declare fectch (in
this case, cache size = 10), returns only 10 rows.

I don't search in other areas, but if you need I can do this.

Another doubt: My Rollback on erros is set to Transaction. But I can see
some SAVEPOINT/RELEASE statements. It's normal ?

Best regards,

Alexandre
