Dynamic Query to display a page of records at a time

Question

I need some help creating procedure with a dynamic query that will query a table and pass out a certain number of records (like records 101 - 200 of 20,000). This procedure will receive the column names, table name, where clause, page number and number of records per page. It will then pass back the requested records to be displayed on a PHP page.
Pseudo Code:
Select Dynamic_Columns, ROWNUM
Into Dynamic_Pl_Sql_Table
From Dynamic_Table
Where Dynamic_Where_Clause
Total_Records_Out := Dynamic_PL_Sql_Table.Count
Modulus := Mod(Total_Records_Out, Total_Records_Per_Page_In)
Total_Pages_Out := (Total_Records_Out - Modulus) / Total_Records_Per_Page_In
If Modulus > 0 Then
Total_Pages_Out + 1
End If
Row_Start = Page_Number_In * Total_Records_Per_Page_In
Row_End = Row_Start + Total_Records_Per_Page_In
Results_Out = Dynamic_Pl_Sql_Table(Row_Start ... Row_End)
Any help with this will be appreciated!

Answer 1

Maybe this will help you
1) If the Serial is 0 then page break
2) total_rows gives you total number of rows selected.
3) you can apply where clause to this and it will give you appropriate records.
select empno, ename, sal, 
mod(row_number() over (order by null),5) serial,
count(*) over () tot_rows from emp ed
     EMPNO ENAME             SAL     SERIAL   TOT_ROWS
      7369 SMITH             800          1         14
      7499 ALLEN            1600          2         14
      7521 WARD             1250          3         14
      7566 JONES            2975          4         14
      7654 MARTIN           1250          0         14
      7698 BLAKE            2850          1         14
      7934 MILLER           1300          2         14
      7788 SCOTT            3000          3         14
      7839 KING             5000          4         14
      7844 TURNER           1500          0         14
