I am comparing data from two tables ,if any difference,display the mismatching records only for auditing purpose.

Example:
Case 1
ACCOUNT_CUST_CD (Not matching from both tables) ,account_contact_person_cd (Matching from both tables)

if account_contact_person_cd matching from both tables ,do not display source and target record.
if ACCOUNT_CUST_CD not matches,displays source and Target values on the same.

1-LPPP( ACCOUNT_CUST_CD --source)
1_1696T( ACCOUNT_CUST_CD --Target)

Case 2

ACCOUNT_CUST_CD , account_contact_person_cd not matches ,returns the source and Target values on the same

1-LPPP 1-411FQ( ACCOUNT_CUST_CD
account_contact_person_cd Source)

1_1696T 1-411FT(ACCOUNT_CUST_CD
account_contact_person_cd Target)

Thanksin advance
