Hi,

How can I realise scope with eXpress++ and SQL Express++ ?

Now I have two DBF files opened with ODBC VFP driver.

From old system with only DBF / CDX system I have code block for Scope :

bOLPD:={||OLPD->(DC_SetScope(0,OLP->C_PROC)), ;
OLPD->(DC_SetScope(1,OLP->C_PROC)), ;
OLPD->(DC_DbGoTop()), ;
oBrowsed:refreshAll()}

How modify it to use SQL express++ ? In eXpress manual I found only info AX_SetScope for Advantage, but nothing about SQL Express.
I do not know, if to bOLPD need use something like this

oBrowsed:refreshAll change to oCursord:refresh()
and what with field names C_PROC for example, because in browse I show it with this :
DATA SQLFieldBlock(oCursord,oCursord:FieldPos("C_PROC"))

Here is part of browsing two databases:

SQLexpress does not support any kind of filter or scope methods. I don't know why. Maybe nobody ever asked Boris for it.
Typically, scoping and filtering are done in the SQL statement with WHERE and ORDER BY clauses.

It is also possible to handle this in the browser for a better user experience but would require writing your own methods and overloading the default :skip(), :gotop(), :gobottom(), :seek() methods that are included in SQLexpress.

Thank's for info,

Ok, now I am trying create statement with WHERE clausule, but this need everytime close and reopen new cursor. At this moment I have some problem with refresh browser after create new cursor... but hope I fix it.

Victorio

but this need everytime close and reopen new cursor.

Yes. This is why dynamic scoping of the current cursor would be a desirable feature.

I do not know how tell to work this :

I want use code block in DCBROWSE :

ITEMMARKED {||Eval(bOLPD), ;
DC_GetRefresh(GetList,, ;
DCGETREFRESH_TYPE_EXCLUDE,(GETLIST_BROWSE)) ;

where bOLPD is some like this :
bOLPD:={||;
oCursord:Close(),;
oCursord := CreateSQLCursor( oConnection, 3, cStatementd ),;
oCursord:GoTop(), ;
oCursord:refresh()}

and statement for create cursor :
cStatementd := 'SELECT RAUKN_OLP_D.C_PROC,RAUKN_OLP_D.DAVKA,RAUKN_OLP_D.DAT_ZAD,RAUKN_OLP_D.CAS_ZAD,RAUKN_OLP_D.STAV,RAUKN_OLP_D.NAZPTK FROM RAUKN_OLP_D.DBF,RAUKN_OLP WHERE RAUKN_OLP_D.C_PROC=RAUKN_OLP.C_PROC AND RAUKN_OLP_D.C_PROC='+{str(oCursor:fieldget(1))}+' ORDER BY RAUKN_OLP_D.C_PROC '

this not work , because problem with this statement :
RAUKN_OLP_D.C_PROC='+{str(oCursor:fieldget(1))}

here I want tell browsers two tables to filter records in second table to show only records with C_PROC number from first table - oCursor:fieldget(1) is field C_PROC.

Second table not refresh, but when I manually set number, and then go to record with seek, works good:
DCADDBUTTON PARENT oToolbarplb ;
CAPTION 'OLP skok OLPD';
ACTION {|| dc_msgbox({oCursor:fieldget(1)}), ;
x:=oCursor:fieldget(1), ;
oCursord:Seek(x),; // triedenie podľa C_PROC
DC_GETREFRESH(GETLIST),tone(200,1) } // refresh prostredia



To ODBC driver Visual Foxpro I go because long delays when user connect to database via VPN and slow LAN.

You need to assign the new cursor to the DC_XbpBrowse() object:

oBrowse:dataSource := oCursord
oBrowse:refreshAll()

Roger,

thanks but I absolutely do not know why this not work for me.

Where can put oBrowse:dataSource:=oCursord
and oBrowse:refreshAll ?

oBrowse is main table with alias OLP , and SQL cursor oCursor
oBrowse is table in relation, his records must be "filtered" by field C_PROC in oBrowse with alias OLPD and SQL cursor oCursord

Now I play with cstatement, because values for this was not accepted, now i use code block

Here is part of test source.

At this moment is relations disabled, I want only after click on button REFRESH-OLPD3 show in secondary table OLPD (oCursorolpd) only records with number C_PROC in main table.

But in second table always after refresh(), refreshall() is default data, interesting is that pointer is on good positon only view is not good.

Please if no lot of time need to look to my source. I mean, there are many strange combinations, so I am still beginner

edit : now I modify source where main table is with SQLselect - as cursor, and second table with dataset - offline
with this combination relation works.

BUT now I do not know why dataset in second table browser show only one record. I must study how dataset work, maybe I need use some array to read dataset items and then show with browser...
