{Test 4: Update, Insert and Delete Queries}
|
40 |
|
41 |
{ This test opens the employee example databases with the supplied user name/password
|
42 |
and runs several queries:
|
43 |
|
44 |
1. Update an employee record and report affected rows.
|
45 |
|
46 |
2. Show Changed Record
|
47 |
|
48 |
3. Insert new employee record and report affected rows Repeat with a duplicated
|
49 |
parameter name.
|
50 |
|
51 |
4. Show inserted record and then delete it and report affected rows
|
52 |
|
53 |
5. Repeat insert with a null PHONE_EXT.
|
54 |
|
55 |
6. Show inserted record and total records
|
56 |
|
57 |
7. Prepare query again and report results
|
58 |
|
59 |
8. Prepare query with a different transaction and report results.
|
60 |
|
61 |
9. Open Cursor with a different transaction and report results.
|
62 |
|
63 |
10. Implicit Rollback and disconnect.
