Full stack trace of any exception that occurs:
No exception occurs.
Name and version of the database you are using:
MSSQL 2000, and Oracle 9.2 (tested what described next only on mssql)
The database has both objects - that have document and those that have not. So when perfoming such kind of search in first case we receive only those that have a document, in the second type - all.
I wonder - why creating aliases influences the results of search, even when those aliases were not used in any criteria. Should it be so?
You may ask - why i do create alias and don't use it - well there is a situation where i should write 1 time create alias, and then perform 10 checks and create a criteria if any of them is true, or i should write 10 times create alias, 1 in every check.
Any help is welcome.
