| 8 | Latest version is available at http://adodb.sourceforge.net |
---|
| 9 | |
---|
| 10 | Portable version of oci8 driver, to make it more similar to other database drivers. |
---|
| 11 | The main differences are |
---|
| 12 | |
---|
| 13 | 1. that the OCI_ASSOC names are in lowercase instead of uppercase. |
---|
| 14 | 2. bind variables are mapped using ? instead of :<bindvar> |
---|
| 15 | |
---|
| 16 | Should some emulation of RecordCount() be implemented? |
