Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4655 fires when a VARCHAR(maximum, reserved) declaration's reserved value isn't between 0 and maximum, inclusive — per the official guidance.

  1. reserved less than 0, per the official guidance — the first named case.
  2. reserved greater than maximum, per the official guidance — the second named case.
Solutions / Resolution
  1. Correct reserved so it falls between 0 and maximum, inclusive, per the official guidance.
Examples
An out-of-range reserved value
DEFINE notes VARCHAR(100, 150)
-- -4655: reserved (150) exceeds maximum (100)
Corrected
DEFINE notes VARCHAR(100, 20)
Diagnostic Checks
  1. Check every VARCHAR(maximum, reserved) declaration, and confirm reserved is between 0 and maximum, inclusive.
