Hi,
U can use lexical parameters for the solutions.U must be aware of it, but still i describe how to work it out.
1)In your datamodel in object navigator create a parameter under User parameter node.Name the parameter, for eg. p_clause.
set data type of parameter to character.
2)write a select query eg.
select * from emp &p_clause; --(THIS IS THE PARAMETER WE CREATED ABOVE)
3)Now run your report
Now in your parameter form pass the value for p_clause parameter.
eg: where name='JACK';
or
where city='NEWYORK';
or where deptno=10;
But do it in steps as above mentioned.
Do tell me if it works or not via mail on [email protected]
