SQL query that change item input

Question

Hi,
I have an application with a region that displays data from a database through a dblink in which the query is dependent on a value input into a couple of items in the application.
Here is the SQL:
SELECT
FROM
rem_rp_tract@DBLINK_WPC29_G6CEFMP1.NWO.USACE.ARMY.MIL "REM_RP_TRACT"
WHERE
"REM_RP_TRACT"."PROJ_ID" = upper(:P2_PROJECT_CODE)
AND "REM_RP_TRACT"."TRACT_NO" = upper(:P2_TRACTNO)
The P2_PROJECT_CODE and P2_TRACTNO values correspond to locations in a map layer in oracle spatial and data in the dblink indicated in the SQL. The problem is that the TRACT is designated with a dash (J-840) in oracle spatial and in the database it is designated without a dash (J840). Therefore, if I input Tract Number J-840 into the item have developed the app and map to zoom to the tract but no data is displayed because the database does not recognize the value. On the other hand, if I input J840 the data from the database will displayed but oracle spatial doesn't recognize it so the map does not zoom to the tract.
What I would like to do is be able to input the value with the dash (J-840) but change the SQL above so that it queries J840, i.e. all values without a dash. Is this possible?
Any help is greatly appreciated,
Kirk

Try This
SELECT *
  FROM rem_rp_tract@DBLINK_WPC29_G6CEFMP1.NWO.USACE.ARMY.MIL "REM_RP_TRACT"
WHERE "REM_RP_TRACT"."PROJ_ID" = upper(:P2_PROJECT_CODE)
   AND "REM_RP_TRACT"."TRACT_NO" = REPLACE(upper(:P2_TRACTNO),'-')
SQL> var myvar varchar2(20);
SQL> exec :myvar:='J-840' ;
PL/SQL procedure successfully completed.
SQL> select :myvar , replace(:myvar,'-') from dual ;
:MYVAR                           REPLACE(:MYVAR,'-')
J-840                            J840Replace the - in the string to null.
