SQL Server best approch to append table data into Oracle database table -


i have table bio-metric devices capture data employees punch fingers , uses sql server 2014 standard edition.

however, our legacy devices exporting log files , used vb engine push our oracle table , used generate attendance details.

i managed export data sql server , built first set of records. schedule job sql server condition oracle table should receive rows not inserted sql server table.

i checked append possibilities, dumps entire sql server table data when job executed duplicating rows within oracle target table, forcing me discard job , build new 1 deletes oracle table , recreates when job executed. feel kind of overkill...

any known methods available append rows not existing in oracle target table? unfortunately sql server tables doesn't have unique id column transaction.

please suggest

thanks in advance

i think best way use sal server replication oracle database subscriber. can read solution on msdn site: oracle subscribers

regards giova
