{Create and Drop a Database}
|
| 7 |
{
|
| 8 |
This test first attempts to create a database without specifying any parameters
|
| 9 |
(should fail). It then goes on to create and drop a database, print out the
|
| 10 |
parameters and then creates it again (will fail if the dropdatabase failed silently.
|
| 11 |
|
| 12 |
Some basic database info is then accessed and printed.
|
| 13 |
|
| 14 |
A basic query is performed and finally the database dropped.
