pre query is executed fefore user goes to input.
it execute only one time for any block

in user parameter property we have list of values.can we write select query for binding? for example:: select empno from emp where deptno=:deptnum :deptnum is first parameter it displays distinct dept nos. if i do like this it is giving error:: bind variables are not allowed in the select statement
