  I am retrieving the values of some positions of a table dynamically.The
position has null(automatically database insert that null value),1,2
values.I have to retrieve that values to a java prog and to check whether
the retrieved value is 1,2 or null.This I am doing like this.
      I reterieves the value using rs1.getString(usrnameDB).

if(rs1.getString(usrnameDB).equals("1"))
else if(rs1.getString(usrnameDB).equals("null"))
   The II line won't work because here the null parameter(entered
automatically in the database)is something different from that is there in
a JAva prog.
  I just want to know how can I check that a retrieved value in this
manner is 1,2 or null.

TIP 2: you can get off all lists at once with the unregister command
    (send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
