Custom query conditions in db adapter

Question

Hello,
How to execute custom query in bpel db adapter?
For example :
1. select * from employee where status = 'N' and address is not null
2. select * from empoyee where substatus = 'Y' and phone is null
after where keyword - query part is dynamic, parameter combinations and count is unlimited ( depends on business logic ). It is not possible to implement each condition parameter as parameter in db adapter configuration.
Db adatper query has to be something like  : select * from employee where #condition# , but #condtion# need to be interpretated as condition not string with quotes..
best Regards,

Say your complete query looks like this -
select SUBJECT_NAME from RELATION
            where PID_GID_SSID IN (select PARTY_KEY from  xref WHERE row_id='123')
1). In assign activity, write out the query part which comes after where clause and assign to variable query
(select PARTY_KEY from  xref WHERE row_id='123') , replace the value of row_id from input value in assign.
2. Now open DB adapter and pass the rest of query as input -
select SUBJECT_NAME from RELATION
            where PID_GID_SSID IN #query
