Enable/Disable column editing in datawindow in rowfocuschanged script

//in rowfocuschanged event in datawindow, write this

long ll_budget

if currentrow > 0 then

ll_budget = this.getitemnumber(currentrow, 'expense')
  
    if ll_budget > 0 then
        this.object.kod_vot.protect = 1   //kod_vot is your column_name
        this.object.dasar.protect = 1       //dasar is your column_name
    else
        this.object.kod_vot.protect = 0
        this.object.dasar.protect = 0
    end if
end if

//this will disable editing if ll_budget is greater than 0 and enable editing if it is zeroin other way you can always do this in datawindow expression.
go to protect expression for the particular column then code this :-

if (budget > 0, 1, 0)

//means when budget value greater than 0, 1 = to protect (disable column edit) else 0 = enabled column edit.

To Enable/disable Editing on new/existing row in datawindow

 //In your datawindow write this code in your column property, in ->General->protect

if (isRowNew(), 0, 1)

//this will enable editing on newrow and disable editing on existing row

//write code in each column to enable/disable editing for a row...

//you can put other conditions like calculation such as

if (columnname = 'Admin', 0, 1)

Having in Select Statement

 // working sample from one of my project that using HAVING select statement...

SUBSTR in Oracle

Let say we have a data like below in a table :-

ABC12345

We can abstract data using

SUBSTR([column],[position from left],[length]) such as below :-

SELECT SUBSTR(a.mycolumn, 4, 5) FROM mytable a;

will result an output :- 12345

Dynamic runtime modifying SQL in datawindow

//let say we have these codes in open window event

string ls_code, ls_SQL, ls_newSQL

ls_code = message.stringparm
dw_1.settransobject(sqlca)

//get existing SQL from dw_1
ls_SQL = dw_1.getsqlselect( )

//dynamicly modify SQL in datawindow by adding where statement...
if ls_code = '-' then
    ls_newSQL = ls_SQL + " where b.KOD_JENIS IS NULL order by b.KOD_PEKA"
else
    ls_newSQL = ls_SQL + " where b.KOD_JENIS = '"+ls_code+"' order by b.KOD_PEKA"
end if

//sets new SQL to dw_1
dw_1.setsqlselect(ls_newSQL)
dw_1.retrieve()

/* example that you have this SQL in dw_1

select b.KOD, b.KOD_JENIS,
       (select c.PIHAK from ppihak c where c.KOD_PIHAK = b.KOD_PIHAK) as pihak,
       b.KOD_PTJ, b.TKH_TTGN, b.TKH_TAMAT, b.TKH_UPDATE, b.ID_UPDATE

Starteam problem starting in PB10

Once i have problem loading starteam when i started my PB10, when select to 'starteam source control' and try to connect, PB10 crashed. After adding some command in pb.ini, problem solved. Didnt remember where got this solution, but it is either from Borland or Sybase forum.

Add below command  into your pb.ini :-

[JavaVM]
CreateJavaVM=0

----------------------------------------------------------------------
(usually pb.ini found in path like this C:\Program Files\Sybase\PowerBuilder 10.0)

i'am using Borland Starteam 2008 released 2 with PB10.2

Using UNION in Oracle

Union will combine two sets of data, see example below :)

select a.KOD_JENIS, a.NAMA_JENIS, count(b.KOD_JENIS)
from ptype a, pmain b
where a.KOD_JENIS = b.KOD_JENIS
group by a.KOD_JENIS, a.NAMA_JENIS
union
select '-', 'No Data', count(*)
from pmain b
where b.kod_jenis is null

CONCAT in Oracle

SELECT CONCAT('Name : ', Upper(a.NAME))
FROM BIODATA a
WHERE a.MATRIK = :matrik;

/*Result Sample :-
Name : HARIMADA SABALKUNAN
*/

ISNUMBER in Oracle

Until Oracle 10g doesnt have ISNUMBER function , this is another way to check either the data is a number or not...(until this written, oracle version used is 10g)

SELECT length(translate(trim(column_name),' +-.0123456789',' ')) FROM DUAL;

Will return you NULL if it is a number, Greater than zero if not number
(Actually returns the count of non numeric characters)

In Real Case will compute as :
SELECT A.KODMP,
   B.SETMP,
   decode(length(translate(substr(B.PENSY, 3, 8), ' +-.0123456789', ' ')), null, substr(B.PENSY, 3, 8), B.PENSY) as IS_STAFNO,
   C.0NMSKGR,
   B.SMGRED,
   DECODE((SELECT D.NAMA FROM FASAS D WHERE D.STAFNO = B.PENSY), NULL, 'Tiada',(SELECT D.NAMA FROM FASAS D WHERE D.STAFNO = B.PENSY )) AS NAMA
FROM FMAKK A, FKURPSY B, 0STSMSKGR C
WHERE B.KODMP = A.KODMP
AND B.SMGRED = C.0KMSKGR
AND A.KODFAK like :kodfak
AND B.SESI = :sesi
AND B.SEMESTER = :semester;
