Agenda

Knowing me – rumours abound Knowing you – Geeks or Managers? Capabilities by example Some Principles of ProDataset Design Other ProDataSet coding tips


Knowing me – it is all true

Progress survivor Voracious appetite for the new Respect of the old A clinical eye for what works Anything else is just rumours…….


Knowing you

Geek • already using proDataSets?

Manager • are the developers telling the truth?

Lagard • Need to get to proDataSets

Nothing else on Information overload …….

Be honest


{include/ttuploadforms.i}.{include/ttformstatus.i}DEF DATASET dsApplication FOR ttUploadForms, ttUploadDetails,ttUploaderrors,ttProperty,ttApplication,ttApplicationParty,ttParty,ttEventhist Data-Relation dr-Forms-Details for ttUploadForms, ttUploadDetails relation-fields (uploadID, uploadID) .Data-Relation dr-Details-Party for ttUploadDetails, ttParty relation-fields (PartyID, PartyID).

What is a prodataset


DEF TEMP-TABLE ttUploadForms NO-UNDO BEFORE-TABLE ttUploadFormsBefore FIELD uploadID AS INT FIELD loadDate AS DATETIME FIELD originalFilename AS CHARACTER FIELD partyID AS INTEGER FIELD processStatus AS CHARACTER FIELD sentToOCRDate AS DATETIME FIELD storedCopyOfFile AS BLOB {include/extrattfields.i} INDEX PK_uploadID IS PRIMARY UNIQUE uploadID.

Is it just a standard temp-table?


Agenda

Capabilities by example• Share your Transport

• Travel by Public Transport

• Use the most appropriate transport package

• Just give me the Transport Link

• It gets your there fast

• But I like shankes pony


Lets go to the code


Agenda

Some Principles of ProDataset Design• Defining Temp Tables

• Name Variations

• What is Reference Only?

• Index ? What Index?

• ROWID


{include/ttparty.i &ext={&ext}}{include/ttproperty.i &ext={&ext}}DEFINE DATASET dsparty{&ext} {&ReferenceOnly} FOR ttparty{&ext}, ttProperty{&ext}, Data-Relation dr-party-prop{&ext} for ttparty{&ext}, ttproperty{&ext} relation-fields (physpropid, propertyid)./* include/ttparty.i */DEFINE TEMP-TABLE ttparty{&ext} BEFORE-TABLE ttparty{&ext}before FIELD Given-Names AS CHARACTER FIELD Surname AS CHARACTER FIELD PartyID AS INTEGER {include/extrattfields.i} INDEX PartyIdx IS PRIMARY UNIQUE PartyID

Sample: 4GL Code Snippet


Agenda

Other ProDataSet coding tips• Is there a Fill in the House?• Did you say Fill in the where string!• Pesky Housekeeping and performance• Save those changes• But I said output!• Generic or specific?• Useful routines and ideas• Did you say ADM2?


Lets go to the code
