Pete...
The MySQL script that works... but just not on a real device...
  /* get the data from the database */
      get revOpenDatabase("mysql","www.xxxxxx.com","xxxxxxxx","xxxxxxx","xxxxxxx")
      put it into gDatabaseRef
      
      get revDataFromQuery( tab, return, gDatabaseRef, "SELECT Name,GPSPosition FROM towns;")
      revCloseDataBase gDatabaseRef
      put empty into gDatabaseRef
      
      set itemDel to tab
      sort lines of it by item 1 of each
      put it into theData
The sqlLite script... works in the IDE but not in the simulator...
/* get the data from the database */
      set the defaultfolder to specialFolderPath("documents")
      put revOpenDatabase("sqlite","localKnow.db",,,,) into gDataBaseRef
      get revDataFromQuery (tab, return , gDataBaseRef, "SELECT * FROM towns" )
      put it into theData
      
      revCloseDataBase gDatabaseRef
take care,Dixie
