This demonstrates the use of TIBStoredProc with the Firebird 3 packages example |
| 9 |
|
|
provided with the Firebird 3 source code. A database is created in a temporary |
| 10 |
|
|
location when the application is first run. Once this completes, IBStoredProc2 calls |
| 11 |
|
|
the global stored procedure "test", which populates the temporary table FB$OUT. |
| 12 |
|
|
|
| 13 |
|
|
IBStoredProc1 then calls the GET_LINES procedure in the FB$OUT package. It returns |
| 14 |
|
|
a text blob which is then printed out. |
