I created this form custom method to allow me to only update the field
if the value has changed. This replaces lots of unconditional REPLACEs
in a form.
LPARAMETERS tcTable, tcField, tvValue
LOCAL lvCurrent as Variant
lvCurrent = EVALUATE(tcTable + "." + tcField)
IF lvCurrent <> tvValue THEN
REPLACE (tcField) WITH (tvValue) IN (tcTable)
ENDIF
(This is in theory yet...implementing it soon.)
So instead of
REPLACE order.cost4des WITH 'Fuel Surcharge'
I call
thisform.UpdateTableValue('order','cost4des','Fuel Surcharge')

We've seen this before (and I did it 2 decades ago): REPLACE
MyTable.MyField with SomeOtherTable.SomeField
The implication is that "replace the MyField value in the MyTable
table." But if one doesn't use the IN clause, will there ever be any
chance that the update to MyTable.MyField would fail?
