G-2330: Never use zero-length strings to substitute NULL.
Blocker
Portability, Reliability
Reason
Today zero-length strings and null
are currently handled identical by the Oracle Database. There is no guarantee that this will still be the case in future releases, therefore if you mean null
use null
.
Example (bad)
1 2 3 4 5 6 7 8 9 10 11 |

Example (good)
1 2 3 4 5 6 7 8 9 |
