Example

var
  hConnection : number;
  cCursor     : cursor;

dcltrans
  transaction TMain
  var
    sName    : string;
    fBalance : float;
  begin
    OraLogon(hConnection, "user", "password", "orclnet2");
    OraOpen(cCursor, hConnection);
    OraParse(cCursor, sqlSelect);
    OraBind(cCursor, ":1", SQLT_FLT);
    OraSetFloat(cCursor, ":1", 2000.0);
    OraDefine(cCursor, 1, SQLT_CHR, 32);
    OraDefine(cCursor, 2, SQLT_FLT);
    OraExec(cCursor);
  
    while OraFetch(cCursor) do
      sName := OraGetString(cCursor, "1");
      fBalance := OraGetFloat(cCursor, "2");
      write(sName, 32); write(fBalance); writeln;
    end;

    OraClose(cCursor);
    OraLogoff(hConnection);
  end TMain;

dclsql
  sqlSelect:
    SELECT * FROM accounts WHERE balance > :1;
