What is this?
_MAIN_UOM_NAME

[shrifw]

Dear Rao Sir ,

It is GET Var as shown below , as TDATAROW added underscore "_" prefix ( _MAIN_UOM_NAME ).

The RowSet Query returns a record.

Code: Select all  Expand view

oItemRs := oApp:oDBConn:RowSet( T_VITEM_REF_COLS_BY_ID( pnItemId ) )  
oItemRec := TDataRow():New( oItemRs )

....

@   nGetRow,  150  SAY ":" GET aoGETRO[ 5 ] VAR oItemRec:main_uom_name SIZE 200, C_GETH PIXEL OF oWnd ;
    WHEN (.F.)  NOBORDER FONT oApp:oFontGet UPDATE

 

Thanks
Shridhar

[nageswaragunupudi]

T_VITEM_REF_COLS_BY_ID( pnItemId )

What does this function Return?

Meanwhile please do this small test:
Immediately after opening the rowset, execute:

Code: Select all  Expand view

oItemRs:Edit()

and let us know what happens.

Dear Rao Sir ,

oItemRs:Edit() is working fine. But after that as usual same error occurs.

I have tested in FWH 23.10 and it is working FINE. But NOT working in FWH 24.04

Code: Select all  Expand view

oItemRs:Edit()

 

Thanks
Shridhar

I have tested in FWH 23.10 and it is working FINE. But NOT working in FWH 24.04

Is oItemRs:Edit() not working in FWH24.04? What is the error you are getting?

[shrifw]

Dear Rao Sir ,

Sorry for the late replying...!!

Is oItemRs:Edit() not working in FWH24.04? What is the error you are getting?

oItemRs:Edit() is working fine in both FWH 23.10 and FWH24.04 version. THE TDATAROW IS NOT WORKING IN VERSION FWH 24.04 BUT IT IS WORKING FINE IN FWH 23.10.

Thanks

oItemRs:Edit() is same as TDataRow():New( oItemRs ):Edit()

Please try

Code: Select all  Expand view

TDataRow():New( oItemRs ):Edit()

and let us know.

[nageswaragunupudi]

In this code

Code: Select all  Expand view

@   nGetRow,  150  SAY ":" GET aoGETRO[ 5 ] VAR oItemRec:main_uom_name SIZE 200, C_GETH PIXEL OF oWnd ;
    WHEN (.F.)  NOBORDER FONT oApp:oFontGet UPDATE

Please do not use WHEN clause. Use READONLY clause
Like this:

Code: Select all  Expand view

@   nGetRow,  150  SAY ":" GET aoGETRO[ 5 ] VAR oItemRec:main_uom_name READONLY ;
SIZE 200, C_GETH PIXEL OF oWnd ;
   NOBORDER FONT oApp:oFontGet UPDATE

[shrifw]

Dear Rao Sir ,

Yes..! , Both Function are working fine. I had overlooked. I tried to change GET with READONLY. But still the error is exists.

oItemRs:Edit() is same as TDataRow():New( oItemRs ):Edit()

TDataRow():New( oItemRs ):Edit()

Error :

Yes..! , Both Function are working fine

TDataRow method Edit() automatically creates Gets for all datas and that is working fine.
Are you able to see the Get for the data itemgrp_name also?

This method automatically recognizes if a data is readonly and then creates the Get suitably.
When these automatically generated Gets are working, the Get you are creating manually is not working.

Please recheck your code.

[shrifw]

Dear Rao Sir ,

I apologize resuming to this topic very late. May I request you to help on this.

Thanks
Shridhar

[nageswaragunupudi]

I will be able to help better if we both work on the same sample, so that I can build and check at my end.

I suggest this:

Code: Select all  Expand view

#include "fivewin.ch"

function Main()

   local oCn, oRs, cSql

   oCn   := maria_Connect( "208.91.198.197:3306,fwhdemo,gnraofwh,Bharat@1950", .t. )
   oCn:lShowErrors := .t.

//
TEXT INTO cSql
SELECT C.ID, C.City, C.State, S.name AS StateName, C.Salary
 FROM customer C LEFT JOIN states S ON C.state = S.code
 WHERE C.ID < 101
ENDTEXT
//
   oRs   := oCn:RowSet( cSql )
   if oRs != nil

// In this Rowset, fields ID and STATEMANE are readonly
// Please build your TDataRow Edit code here
// reproduing the error

      oRs:Close()

   endif
   oCn:Close()
   
return nil

and test it at your end
I will also test at my end.
Then it is easy for me to provide support
