Venkata,

Yes.
Create a public variable in a PL/SQL package stored in the database. Reference that public variable in the where clause of your view and populate that variable before you select from the view. Since each session gets its own instantiation of the packaged variable, each session uses a "customized" version of the view. It's a handy technique!

BTW, create the variable with a default value (Null or some "real" value) such that the view will work as desired even if the variable is not explicitly assigned a value.

Dear All,
Is it possible to create a view where I will pass the condition to the where clause dynamically.

eg)
Create view v1 as select ename,empno,sal from emp where deptno=:a

The value of 'a' I will pass the value dynamically when I do the select.

eg) select * from v1.
Now I'll pass the value say 20.

Is this possible

Any suggestions or workaround for this.

TIA Regards

Venkata
