|
|
{ This test opens the employee example databases with the supplied user name/password |
9 |
|
|
and runs several queries: |
10 |
|
|
|
11 |
|
|
1. Update an employee record and report affected rows. |
12 |
|
|
|
13 |
|
|
2. Show Changed Record |
14 |
|
|
|
15 |
|
|
3. Insert new employee record and report affected rows Repeat with a duplicated |
16 |
|
|
parameter name. |
17 |
|
|
|
18 |
|
|
4. Show inserted record and then delete it and report affected rows |
19 |
|
|
|
20 |
|
|
5. Repeat insert with a null PHONE_EXT. |
21 |
|
|
|
22 |
|
|
6. Show inserted record and total records |
23 |
|
|
|
24 |
|
|
7. Prepare query again and report results |
25 |
|
|
|
26 |
|
|
8. Prepare query with a different transaction and report results. |
27 |
|
|
|
28 |
|
|
9. Open Cursor with a different transaction and report results. |
29 |
|
|
|
30 |
|
|
10. Implicit Rollback and disconnect. |
