• FWMariaRowSet:

• SetGet method PrimaryVal: Fixed bug when record pointer is invalid.

• Method Requery(...) Enhancement: It is now possible to read a totally
  different table/sql.
  Syntax:
  :Requery( cNewSq, aParams ) // same params as for oCn:RowSet() reads
  a new rowset data into the present Rowset, replacing the existing data.
  Other syntax already availabe in previous versions also:
  :Requery() // re-read same sql without changing params if any
  :Requery( aParams ) // re-read same sql with new params
  Example:
  oRs := oCn:RowSet( "select * from states where id > ?", {20} )
  // do something with oRs
  oRs:Requery( "select * from customer where age > ?",{45} )
  // now oRs is a new table
