GOAL:
Is it possible to have a dynamic FIND
GOAL:
Implement dynamic FIND
FACT(s) (Environment):
Progress 9.1D
FIX:
In version 9.1D, new buffer object methods and attribute that would provide stand-alone FIND support for dynamic buffers have been implemented:
Buf-hdl:FIND-UNIQUE
Buf-hdl:AMBIGUOUS
Buf-hdl:FIND-CURRENT
Buf-hdl:FIND-FIRST
Buf-hdl:FIND-LAST
These methods and attribute allow stand-alone finding on a dynamic buffer object. They complement the already existing Buf-hdl:FIND-BY-ROWID.
Example:
=======
DEFINE VARIABLE bh AS HANDLE.
bh = BUFFER customer:HANDLE.
bh:FIND-LAST("where balance > 0 use-index name").
MESSAGE NAME.
bh:FIND-LAST("where cust-num > 5 and address < 'z'").
MESSAGE NAME.
