1 A16: proDataSets in the Real World aka blood, sweat and tears revisited Miles Klettke Clever Fellow

2 © 2008 Progress Software Corporation 2 Agenda  Knowing me – rumours abound  Knowing you – Geeks or Managers?  Capabilities by example  Some Principles of ProDataset Design  Other ProDataSet coding tips

3 © 2008 Progress Software Corporation 3 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…….

4 © 2008 Progress Software Corporation 4 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

5 © 2008 Progress Software Corporation 5 {include/ttuploadforms.i}. {include/ttformstatus.i} DEF DATASET dsApplication FOR ttUploadForms, ttUploadDetails,ttUploaderrors,ttProperty,ttApplic ation,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

6 © 2008 Progress Software Corporation 6 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?

8 © 2008 Progress Software Corporation 8 Lets go to the code

9 © 2008 Progress Software Corporation 9 Agenda  Some Principles of ProDataset Design Defining Temp Tables Name Variations What is Reference Only? Index ? What Index? ROWID

10 © 2008 Progress Software Corporation 10 {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

11 © 2008 Progress Software Corporation 11 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?
