Select query with variable no of conditions

Question

Hi,
I want to write a select query such that the conditions mentioned under WHERE clause can be variable .like :
Select * from TABLE where F1 = var1 and F2 = var2 and F3 = var3.
Now on the basis of some conditons the equations in where clause should be used.Say condition is variable value >6.
Now in this case ,if
var1 =7 var2 =3 var3 = 8 then the query shud behave like
select * from TABLE where F1 = var1 and F3 = var3
if :
var1 =3 var2 = 4 var3 =3 the :
select * from TABLE
But only one query is to be wrote that satisfies all of these
thanx

Hi Aachal,
Use Dynamic select statement.
Ex:
data : lv_wherecond type string.
Select * from TABLE where ( lv_wherecond ).
Before Select stmt, code as follows.
if var1 > 6.
       if lv_wherecond is initial.
          F1 = var1.
       else.
          concatenate lv_wherecond ' and F1 = var1'  into lv_wherecond.
       endif.
elseif var 2 > 6.
        if lv_wherecond is initial.
           F2 = var2
        else.
           concatenate lv_wherecond ' and F2 = var2'  into lv_wherecond.
       endif.
elseif var3 > 6.
      same as above ..
endif.
Hope it helps..
