tArrayData

[Marcelo Roggeri]

Buenas noches, estoy necesitando filtrar en un tArrayData por fecha y no logro hacerlo, me da error.
Ejemplo: 1

Code: Select all

          cFilter += [id_cliente=] + FW_ValToSQL(::id_contribuyente) + " "
          cFilter  += " .AND. " + [DTOS(cpte_fecha)>=] + ClipValue2SQL(DTOS(dFecDes))          
          cFilter  += " .AND. " + [DTOS(cpte_fecha)<=] + ClipValue2SQL(DTOS(dFecHas))
 

Time from start: 0 hours 0 mins 14 secs
Error occurred at: 31/08/2020, 19:08:38
Error description: Error BASE/1003 Variable does not exist: CPTE_FECHA

Ejemplo:2

Code: Select all

          cFilter  += " .AND. " + [cpte_fecha>=] + FW_ValToSQL(dFecDes)
          cFilter  += " .AND. " + [cpte_fecha<=] + FW_ValToSQL(dFecHas)

When you use a TArrayData object, use filters with familiar Clipper/Harbour syntax.
Build filter expressions exactly the same way you do for DBF.

Example:

Code: Select all

cState := "NY"
dDate := STOD( "19990101" )

// cFilter := "STATE = '" + cState + "' .AND. HIREDATE >= STOD( '" + DTOS( dDate ) "' )"  // This is difficult to write
// Here is a simple way

cFilter := DBF_ApplyParams( "STATE = ? .AND. HIREDATE >= ?", { cState, dDate } )

oData:SetFilter( cFilter )

Instead of this:

Code: Select all

         cFilter += [id_cliente=] + FW_ValToSQL(::id_contribuyente) + " "
          cFilter  += " .AND. " + [DTOS(cpte_fecha)>=] + ClipValue2SQL(DTOS(dFecDes))          
          cFilter  += " .AND. " + [DTOS(cpte_fecha)<=] + ClipValue2SQL(DTOS(dFecHas))
 

Use this code:

Code: Select all

cFilter := DBF_ApplyParams( "id_cliente = ? .AND. cpte_fecha >= ? .AND. cpte_fecha <= ?", { ::id_contribuyente, dFecDes, dFecHas } )

Easy to write, easy to understand and easy to maintain and most importantly, bug-free.

Note: The function DBF_ApplyParams() was first released in FWH1905.

Buenas tardes Mr Rao
Anduvo perfecto, muy agradecido haces desde el domingo que estoy con esto pero quería agotar todas las posibilidades antes de molestar.
Corrijo el mensaje,
Me da este error usandolo asi tal cual:

cFilter := DBF_ApplyParams( "id_cliente = ? .AND. cpte_fecha >= ? .AND. cpte_fecha <= ?", { ::id_contribuyente, dFecDes, dFecHas } )

Use the field name that exists in your TArrayData object.

[Marcelo Roggeri]

Asi es Mr Rao. utilizo _ que se corresponden.

We will check and come back to you.
Let us also know your FWH version.

[nageswaragunupudi]

Firstly, thank you for bringing this problem to our notice.
There is a bug when the same field name is used twice in the same expression.

This is fixed in the next version to be released.

If you let us know the FWH version you are using, we will also provide you the solution suitable for your version.

This is the fix:

\fwh\source\function\vstrfun1.prg
function FW_ExprnAsBlock(....)

Please locate these lines: (353 to 359)

Code: Select all

   if ValType( cFormat ) == "B"
      AEval( aStruct, { |a,i| FW_At( c := Trim( a[ 1 ] ), @cTran, nil, nil, .t., .t., nil, ;
             Eval( cFormat, i, c ) ) } )
   else
      AEval( aStruct, { |a,i| FW_At( Trim( a[ 1 ] ), @cTran, nil, nil, .t., .t., nil, ;
             Transform( i, cFormat ) ) } )
   endif
 

Substitute with:

Code: Select all

   if ValType( cFormat ) == "B"
      AEval( aStruct, { |a,i| FW_At( c := Trim( a[ 1 ] ), @cTran, nil, nil, .t., .t., nil, ;
             Eval( cFormat, i, c ), .t. ) } )
   else
      AEval( aStruct, { |a,i| FW_At( Trim( a[ 1 ] ), @cTran, nil, nil, .t., .t., nil, ;
             Transform( i, cFormat ), .t. ) } )
   endif

Mr Rao muchas gracias por tomarse el tiempo de solucionarlo.
Mi version de FWH es la July 2020

Is it working for you now with this fix?

Si Mr. Rao funciona a la perfección ahora
