{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. |
