Find Record

Languages Focus

Finding a record is about moving a cursor to a specific record within a set of records (documented here). In addition to finding a record, you can sort, filter, and loop a set of records (documented in their topics).

Corel Paradox:   locate, qLocate

ObjectPAL provides a rich set of commands for finding a record with a TCursor or UIObject including:

  • locate() -  Seach for a value based on a criteria. Uses indexes as appropriate.
  • locatePattern() - Search for a pattern within a value.
  • moveToRecord() - Moves to a specific record number.
  • qLocate() - Search using currently set index.

Each of these basic find record commands has supporting commands such as locateNext() and recNo().

Syntax Example:
var
  tc TCursor
endVar
   
tc.open("Customer.db") 
if tc.locate("Name", "Proffessional Divers, Ltd.") then 
  tc.edit()
  tc.Name = "Professional Divers, Ltd."
  msgInfo("Success", "Corrected spelling error.")
endIf
tc.endEdit()
