Informix Error -29030: Feature feature-name not supported by the Gateway.
Cause and resolution
Feature feature-name not supported by the Gateway.
The Gateway product does not support this feature. (For example, it does not support Informix-specific SQL statements or Informix-specific data types.) The feature that is not supported is returned as a token in SQLERRM.
Correct the application and do not use any feature that the Gateway cannot support on SQL statements that will go through the Gateway during execution.

data type) the Gateway product doesn't support — per the official guidance, the
unsupported feature is returned as a token in SQLERRM.
- An Informix-specific SQL statement or data type used on a statement routed through the Gateway, per the official guidance — the direct, only cause.
Solutions / Resolution

Examples
