EXPORT bug after patch installed

Question

Hi, I have big problem. In SQL Developer 1.5.4 without patch I succesfully exported query results into various formats. But today I installed patch. Export doesn't work, displays error message ORA-00936 - missing expression. I tried uninstall patch (remove these files - "The patch is made up of two parts, the file sqldeveloper.1.5.4.jar will be installed into the \sqldeveloper\ide\lib\patches folder and the file oracle.sqldeveloper.patch.jar into the \sqldeveloper\sqldeveloper\extensions folder. To remove the patch, delete these two files and restart SQL Developer") but export still don't work.
Anybody could help me?

Answer 1

Hi, original query I can't send, but I reproduced this error with these query:
select dbt.* from dba_tables dbt, dba_users dbu
where dbt.owner = dbu.username
and dbu.username = 'SYS'
If I used these query:
select * from dba_tables dbt, dba_users dbu
where dbt.owner = dbu.username
and dbu.username = 'SYS',
export works fine.
And I reproduce error if I used schema name precedes table names in query (i.e. hr.employees) instead only table names (via public synonyms)
