How to search all tables and all fields for a string? - progress-4gl

Question

I want to search all fields in all tables of a database for a user supplied value and display records which contain that input keyword. Something like this:
FOR EACH _file WHERE (NOT _file-name BEGINS "_" AND NOT _file-name BEGINS "sys")
NO-LOCK:
FOR EACH _field OF _file
NO-LOCK:
ASSIGN
ttable = _file._file-name
tfield = _field._field-name .
FOR EACH &ttable WHERE ttable.tfield MATCHES "urpon frisbee "
NO-LOCK :
MESSAGE "hai"
VIEW-AS ALERT-BOX INFO BUTTONS OK.
DISPLAY _file._file-name .
END.
END.
END.

You want to study "dynamic queries".
procedure x:
define input parameter tbl as character no-undo.
define input parameter fld as character no-undo.
define input parameter xyz as character no-undo.
define variable qh as handle no-undo.
define variable bh as handle no-undo.
define variable fh as handle no-undo.
create buffer bh for table tbl.
create query qh.
qh:set-buffers( bh ).
qh:query-prepare( "for each " + tbl ).
qh:query-open.
qh:get-first( no-lock ).
do while qh:query-off-end = no:
fh = bh:buffer-field( fld ).
if fh:buffer-value = xyz then /* needs special handing if there are array fields in the db ... */
do:
display tbl fld bh:recid fh:buffer-value.
pause.
end.
qh:get-next( no-lock ).
end.
delete object bh.
delete object qh.
return.
end.
for each _file no-lock where not _hidden:
for each _field no-lock of _file:
if _data-type <> "character" then next. /* skip non-char fields */
run x ( _file-name, _field-name, "urpon frisbee" ).
end.
end.
