{Test 5: Update/Insert Returning and Activity Check} |
| 12 |
|
| 13 |
{ This test opens the employee example databases with the supplied user name/password, |
| 14 |
reconnects, and runs several queries: |
| 15 |
|
| 16 |
1. Update an employee record, return LAST_NAME,and report affected rows. |
| 17 |
|
| 18 |
2. Show Changed Record |
| 19 |
|
| 20 |
3. Insert new employee record, return FULL_NAME and report affected rows. |
| 21 |
|
| 22 |
4. Show inserted record |
| 23 |
|
| 24 |
5. Check attachment and transaction activity and ensure reset. |
| 25 |
|
| 26 |
6. Show total records and confirm attachment and transaction activity |
| 27 |
|
| 28 |
7. Implicit Rollback and disconnect. |
