When trying to dynamically set the USING
fields of BUFFER-COMPARE, I get the following error.
WARNING: The USING phrase of the BUFFER-COMPARE statement only honors fields in the source buffer. Ignoring 'cFieldsToCompare'. (5379)
Here is a code sample to clarify, I would like to only compare Field1, Field2, Field4 between buf_target
and buf_origin
. However, I can't simply write the fields down because they are provided and won't always be the same.
DEFINE VARIABLE cChangedFields AS CHARACTER NO-UNDO.
DEFINE VARIABLE cFieldsToCompare AS CHARACTER NO-UNDO.
cFieldsToCompare = "Field1,Field2,Field4"
BUFFER-COMPARE buf_target
USING cFieldsToCompare
TO buf_origin
SAVE RESULT IN cChangedFields NO-ERROR.
Is there a syntaxe that allow BUFFER-COMPARE
to receive fields to compare dynamically?
You can use the BUFFER-COMPARE method of the Buffer handle:
BUFFER buf_target:BUFFER-COMPARE (BUFFER bug_origin:HANDLE, ?, cExceptFields, cFieldsToCompare) .
