Informix Error -2895

Reasons / Common Causes

-2895 is a compiler warning, not a hard error — per the official guidance, the character field's size (as shown in SCREEN) differs from the size of its associated database column, and it only appears because the -v option was passed to the form compiler to request warnings of this type.

1. A display field's declared size differs from its associated column's actual size, per the official guidance — the direct cause.
2. Only surfaced because the form compiler was invoked with -v, per the official guidance — this is a warning, not a hard error.

Solutions / Resolution

1. Decide whether the mismatch is intentional (e.g. deliberately showing a truncated view of a longer column) or accidental, per the official guidance.
2. If accidental, adjust the display field's width in SCREEN to match the column's actual size, per the official guidance.
3. Omit -v when compiling if these warnings aren't of interest.

Examples

Compiling with warnings enabled

form4gl -v myform.per

Adjusting field width to match the column

SCREEN
{
Description: [descr                              ]
}
END

Diagnostic Checks

1. Check the declared width of the display field in SCREEN against the column's actual size (e.g. via syscolumns), and decide whether the mismatch is intentional.
