Problem using SQR 6.0 with oracle 7.3

[Venky Kodunthirapully <r3091c@EMAIL.SPS.MOT.COM>]

hi ,
 when i run my sqr query on oracle i get this error message
(SQR 5528) ODBC SQL dbexec: SQLExecute error 0 in cursor 1:
   [INTERSOLV][ODBC Oracle driver]Data type for parameter 1 has changed
since first SQLExecute call.

Error on line 52:
   (SQR 3723) Problem executing cursor.

SQR: Program Aborting.

Cursor Status:

 Cursor #1:
   SQL = SELECT DISTINCT mfg_area_Cd  from mfg_inventory_sum where
part_id =
         ?
 Compiles = 1
 Executes = 1
 Rows     = 1


is anyone aware of a fix for this ?
thanks
