MS Access link tables returning only first row multiple times -


i'm using ms access 2013, database linked tables attaching oracle 11 database. have 14 linked tables, linked views in oracle. i've created queries each linked table , used create forms. have 1 main form employee search , drives remaining forms , individual queries. @ first queries worked expected , showing appropriate data each employee. i've gone in , made changes , recreated links, data returned not working.

when search employee "bob" , @ "bobs" job history, expect see 24 rows of job history. show first record of job history duplicated 24 times.

when execute views in oracle, see. correct information

access needs primary key in oracle table (or view!) display data properly. problem having indicates access not able recognize usable primary key in table.

for tables, make sure table has primary key , check if datatype usable access. access can use 32bit integers. bigger numbers treated double, bad primary keys due floating point inaccuracies.

while oracle-views not have primary key, still need field (or combination of fields) access can use uniquely identify records. when linkin view, access prompt unique key. choosing non unique field result in problem describing.

open linked oracle-tables/view in access in designview , check, primary keys access using tables.
