1. Create an empty database and populate with a single table including an array of integer column.
|
43 |
|
44 |
2. Select all and show metadata including array metadata.
|
45 |
|
46 |
3. Insert a row but leave array null
|
47 |
|
48 |
4. Show result.
|
49 |
|
50 |
5. Update row with a populated array and show results.
|
51 |
|
52 |
7. Reopen cursor but before fetching array, shrink bounds
|
53 |
|
54 |
8. Fetch and print array with reduced bounds.
