Informix Error -2034: This feature is not available for IBM Informix SQL. It is available for IBM Informix 4GL by using the "form4gl" form builder.

Cause and resolution

This feature is not available for IBM Informix SQL. It is available for IBM Informix 4GL by using the "form4gl" form builder.

The PERFORM form compiler and the 4GL form compiler accept very similar form specifications, but they differ in some features. This statement uses a 4GL feature, but PERFORM cannot process it.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-2034 fires when a form specification uses a feature the PERFORM (ISQL) form compiler doesn't support, even though the PERFORM and 4GL form compilers otherwise accept similar specifications — per the official guidance, that feature is specifically a 4GL-only capability, available via the form4gl form builder.

  1. A form specification using a 4GL-specific feature, compiled with the PERFORM (ISQL) form compiler instead of form4gl, per the official guidance — the direct, only cause.
Solutions / Resolution
  1. Use the form4gl form builder in IBM Informix 4GL instead, per the official guidance, if the 4GL-specific feature is genuinely needed.
  2. Or modify the form specification to use only features PERFORM supports, per the official guidance, if staying on ISQL/PERFORM is required.
Examples
Compiling with form4gl instead of PERFORM
$ form4gl order_entry
Diagnostic Checks
  1. Identify the specific feature triggering the error, and confirm whether it's genuinely 4GL-specific, per the official guidance's framing.
