Subject RE: IBatis Random ORA-01722: invalid number error
Date Thu, 11 Sep 2008 12:05:16 GMT
For the first two alter session statements, would those occur within a logon trigger for the
account?  I'm wondering what you mean by "after you get the connection".  For the other two,
I can just write two additional statements that are fired before and after this query.

I really appreciate the assistance on this.  It's happening sporadically in 3 different queries.
 They all use HashMaps as parameters and HashMaps as the return results.  I don't know if
that's an issue, but I thought I'd mention it again.

    if you have the iBatis logs and all seems ok I suggest you to enable the oracle trace
with the following instructions these one should be issued after you get the connection alter
session set timed_statistics=true; alter session set max_dump_file_size=unlimited;

these one should be issued before executing the sql
alter session set events '10046 trace name context forever, level 12' ;

these one should be issued after executing the sql
alter session set events '10046 trace name context off';

Oracle should produce a trc file in the $ORACLE_HOME/<some_path>/udump directory of
the server you can analyze the file by yourself (it's not veary understandable at firt sigth)
or with tkprof. in the trc files you can see the value of the bind variable, the type and
the error. with these information it should be easy to diagnose the issue. Giovanni
