{ This test opens the employee example databases with the supplied user name/password,
|
| 9 |
reconnects, and runs several queries:
|
| 10 |
|
| 11 |
1. Update an employee record, return LAST_NAME,and report affected rows.
|
| 12 |
|
| 13 |
2. Show Changed Record
|
| 14 |
|
| 15 |
3. Insert new employee record, return FULL_NAME and report affected rows.
|
| 16 |
|
| 17 |
4. Show inserted record
|
| 18 |
|
| 19 |
5. Check attachment and transaction activity and ensure reset.
|
| 20 |
|
| 21 |
6. Show total records and confirm attachment and transaction activity
|
| 22 |
|
| 23 |
7. Implicit Rollback and disconnect.
