The ALTER TABLE command is not supported on cursors with long field names (longer that 10 characters).

>I am trying to ALTER a cursor that has a logical field to numeric. The cursor is readwrite. When I issue:
>ALTER TABLE cursorname ALTER COLUMN fieldname I
>then I am getting "Invalid operation for the cursor".
>But if I browse that cursor, then go to Properties and manually change one of the fields type, then after this I can run my command with no problem. Why it is working that way?
