i have a table where there are two or more field which can be passed as parameters to filter rows or i can select all of the rows, how can i achieve this using where clause.
REATE TABLE OT_JOB_STAT ( JOB_NO VARCHAR2(12),JOB_STATUS VARCHAR2(12),JOB_EQUIP VARCHAR2(12),JOB_TYPE VARCHAR2(12))
insert into ot_job_stat ( JOB_NO ,JOB_STATUS ,JOB_EQUIP ,JOB_TYPE ) values ('0001','Open','CNC1','Prev')
insert into ot_job_stat ( JOB_NO ,JOB_STATUS ,JOB_EQUIP ,JOB_TYPE ) values ('0002','Close','CNC2','Brk')
select * from ot_job_stat where nvl(job_status) in ('Open') or nvl(job_status)='All' --All should bring both the records.
situation becomes more critical when there are more parameters.
select * from ot_job_stat where nvl(job_status,'X') in (:p_status) or nvl(job_status,'X')='All' and
nvl(Job_type,'X') in (:p_type) or Nvl(Job_status,'X')='All'

thanks littlefoot for the prompt response, but the problem is user will be selecting the value from list box , he may select open or close , if he doesnt select anything then all the records should appear.
i mean something like 1=1 logic which should bring all the records if there is no selection.
Somewhat similar to dynamic where clause.
CREATE TABLE OT_JOB_STAT ( JOB_NO VARCHAR2(12),JOB_STATUS VARCHAR2(12),JOB_EQUIP VARCHAR2(12),JOB_TYPE VARCHAR2(12))
insert into ot_job_stat ( JOB_NO ,JOB_STATUS ,JOB_EQUIP ,JOB_TYPE ) values ('0001','Open','CNC1','Prev')
insert into ot_job_stat ( JOB_NO ,JOB_STATUS ,JOB_EQUIP ,JOB_TYPE ) values ('0002','Close','CNC2','Brk')
select * from ot_job_stat where nvl(job_status) in ('Open') or nvl(job_status)='All' --All should bring both the records.

Yes, "all" would evaluate to "where 1 = 1". You just need to program it; default clause might always be "where 1 = 1", and then you'd just - if needed - add additional condition(s).
