MariaDB FWMaria OrdWildSeek (Solved)

[ctoas]

Hello friends

I have 2 functions that I used for incremental letter-by-letter search with DBF that I adapted for MariaDB.
In this case, the first first part where I search letter-by-letter is working perfectly, but when I try to go to the next record using the same search string it doesn't work.

Code: Select all  Expand view  RUN

oRs := oServer:RowSet( "SELECT nome,r_social FROM agenda ORDER BY r_social" )

Code: Select all  Expand view  RUN

       @ 0069,0000 XBROWSE oBrwAGENDA OF oDlgAGENDA SIZE 0520,0230 STYLE FLAT PIXEL NOBORDER DATASOURCE oRS//AUTOSORT   
            
        ADD TO oBrwAGENDA DATA oRs:r_social PICTURE "@!" HEADER "Razão Social" WIDTH 520
        ADD TO oBrwAGENDA DATA oRs:nome     PICTURE "@!" HEADER "Nome"         WIDTH 520                 

        oBrwAGENDA:nColDividerStyle := 0          
        oBrwAGENDA:nRowDividerStyle := 0          
        oBrwAGENDA:nMarqueeStyle    := 5
        oBrwAGENDA:lHScroll         := .F.
        oBrwAGENDA:lVScroll         := .T.
        oBrwAGENDA:lRecordSelector  := .F.
        oBrwAGENDA:bKeyChar         := {|nKey|IIF(nKey==VK_RETURN,((OPERACAO_AGENDA(2))),)}
        oBrwAGENDA:bClrSelFocus      := {||{nRGB(000,000,000),nRGB(150,150,150)}}
        oBrwAGENDA:bClrSel           := {||{nRGB(000,000,000),nRGB(150,150,150)}}
        oBrwAGENDA:bClrStd           := {||{CLR_BLUE,IIF(oRS:KeyNo() %2==0,CLR_WHITE,nRGB(232,232,232))}}
        oBrwAGENDA:nHeaderHeight    := 40
        oBrwAGENDA:bClrHeader       := {||{nRGB(000,000,000),nRGB(150,150,150)}}
        oBrwAGENDA:bSeek            := {|c|.F.}
           
        oBrwAGENDA:aCols[1]:oHeaderFont := ARIAL16B
        oBrwAGENDA:aCols[1]:bLClickHeader := {|r,c,f,o| nil}
        oBrwAGENDA:aCols[2]:oHeaderFont := ARIAL16B  
       
        oBrwAGENDA:CreateFromCode()
 

Here I do the research in a GET

Code: Select all  Expand view  RUN

@ 0045,0560 GET oGetPESQUISA VAR cPESQUISA PICTURE "@!" SIZE 0455,0020 PIXEL FONT ARIAL14B OF oBarAGENDA ON CHANGE(PESQUISA(oGetPESQUISA,oBrwAGENDA,oRS))

Button that sends to the next record

Code: Select all  Expand view  RUN

@ 0045,1018 BTNBMP oBtnPROXIMO RESOURCE "BTN_PROXIMO" OF oBarAGENDA SIZE 0020,0020 PIXEL FLAT NOBORDER ACTION PROXIMO(cPESQUISA,oBrwAGENDA,oRS)

Search and next functions

Code: Select all  Expand view  RUN

********************************************************************************
STATIC FUNCTION PESQUISA(_oGetPesquisa,_oBrwPESQUISA,_oRS)

    LOCAL cCHAVEPESQUISA := ""

    cCHAVEPESQUISA:=(_oGetPesquisa:oGet:Buffer)
   
   _oRS:ORDWILDSEEK("*"+ALLTRIM(cCHAVEPESQUISA)+"*",.F.)

    _oBrwPESQUISA:REFRESH()    

RETURN NIL

    IF _oRS:EOF()
        _oRS:DBGOTOP()
    ENDIF
   
    _oBrwPESQUISA:REFRESH()    
                                                     
RETURN NIL

Seeking for the first occurrence:

Code: Select all  Expand view  RUN

if oRs:OrdWildSeek( cSeek )
   oBrw:Refresh()
else
   MsgInfo( "not found" )
endif

Seeking for the next occurrence:

Code: Select all  Expand view  RUN

nSaveRec := oRs:RecNo()
oRs:Skip( 1 )
if oRs:OrdWildSeek( cSeek, .t. )
   oBrw:Refresh()
else
   oRs:GoTo( nSaveRec )
   MsgInfo( "not found"
endif

if oRs:OrdWildSeek(...) succeeds, it returns .T. and if it failed, it returns .F., but does not move the record pointer.
It does not move to Eof() like DBF. So, please do not check for Eof()

Hi Nages,

Seeking for the next occurrence:

Code: Select all Expand view
nSaveRec := oRs:RecNo()
oRs:Skip( 1 )
if oRs:OrdWildSeek( cSeek, .t. )
oBrw:Refresh()
else
oRs:GoTo( nSaveRec )
MsgInfo( "not found"
endif

Unfortunately it didn't work, the skip runs, but OrdWildSeek doesn't.

Whenever you post in the forums, please indicate the version of FWH you are using. That will make it easier for us to support you better.

Please copy this sample program to your fwh\samples folder and build with buildh.bat or buildx.bat. I understand this is the functionality you are looking for.

Code: Select all  Expand view  RUN

#include "fivewin.ch"


function Main()

   local oCn, oRs
   local oDlg, oFont, oBrw, oGet, oBtn
   local cSeek := Space( 60 )

   oCn   := FW_DemoDB( 6 )
   oRs   := oCn:RowSet( "select first,last,city from customer" )
   oRs:Sort := "first"

   SetGetColorFocus()

   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-16
   DEFINE DIALOG oDlg SIZE 700,600 PIXEL TRUEPIXEL FONT oFont

   @ 20, 20 GET oGet VAR cSeek SIZE 300,26 PIXEL OF oDlg UPDATE
   oGet:bChange := <||
      if oRs:OrdWildSeek( "*" + Trim( oGet:oGet:buffer ) + "*" )
         oBrw:Refresh()
      else
         return .f.
      endif
      return nil

   oBtn:bAction := <||
      local nSaveRec := oRs:RecNo()

      oRs:Skip( 1 )
      if oRs:OrdWildSeek( "*" + Trim( cSeek ) + "*", .t. )
         oBrw:Refresh()
      else
         ? "not found"
         oRs:GoTo( nSaveRec )
      endif
      return nil

Thanks for the help Nages.

Perfect!
