How Can I redirect to Error Page

Question

Hi
I have below requirement to insert records into a table based on entered search criteria. And same time don't want to insert the records if there are already records for same search criteria. For this we have done below steps
1) We have a page with two Date fields.
i) Date From
ii) Date To
2) User enters Date From and Date To values and he press "Go" Button.
We have created a Validation at page level of type "Function Returning Boolean".
We are passing two searching Date From and Date To values to function and returning TRUE if there are already records.
Now when condition is TRUE then we want to redirect to a new Page.
How can we do this?
Appreciate if somebody can help me.

Here is the actual situation.
Let us assume I want to populate EMP_TMP table from EMP table.
For this on my first page I have two Fields which are
1) From Date
2) To Date
I am going to give some values to these two fields and I press a button.
Basically what I have to do is
INSERT INTO EMP_TMP
SELECT * FROM EMP
WHERE TRUNC(HIREDATE) BETWEEN TO_DATE(:P_DATE_FROM, 'DD-MON-YYYY') AND TO_DATE(:P_DATE_TO, 'DD-MON-YYYY')
But before doing this I want to validate whether for given date range already data exist in EMP_TMP table or not?
If Already data exist then I have to redirect to User to one page which showing some details.
IF data is not there then I have to insert these records into EMP_TMP table and show those records into another page.
I have given this example on EMP table. But I was having similar example here.
Could you please let me know how can I achieve this.
