Lucas,

Mailed you last version.

cCondicion := "Dtoc( FIELD->FECHA ) >= " + chr( 34 ) + Dtoc( dFecha1 ) + chr( 34 ) + ;
" .AND. Dtoc( FIELD->FECHA ) <= " + chr( 34 ) + Dtoc( dFecha2 ) + chr( 34 )



SET FILTER TO alltrim( AUXILIAR->RELACION ) == alltrim( STR( oData:Codigo ))


cCondicion := "CONTA->CONCEPTO = " + chr( 34 ) + alltrim( cValToChar( cCuentaoConcepto ) ) + chr( 34 )

These should be ok since the are simply cleaned from expression because they are only conversion functions.

But when we use "extraction" functions like month etc I cant see how it can works because they are out of scope in :filter.

[AHF]

Lucas,

No, the replace is as follows:

REPLACE FIELD->FECHA WITH Date().

Here with MySql it works so must be a configuration issue.

Here fielddate is:
FIELDDATE DATE NULL DEFAULT NULL;
All other options empty

[AHF]

Lucas,

Your MySql innoDB ?

Antonio,

With the version you just send me, there are some bugs so far:

At, ADOFINDREC(), oRecordSet:AbsolutePosition := IF( oRS:AbsolutePosition == adPosEOF, oRS:RecordCount() + 1, oRS:AbsolutePosition ) is failing, as IF( oRS:AbsolutePosition == adPosEOF, oRS:RecordCount() + 1, oRS:AbsolutePosition ) its giving -1, which is not possible.

HBRECNO is not created by default. Also, the code at ADO_OPEN is not being proccessed to add it.

I suggested to simple add it to ADOCREATE(), which is the easiest way as explained before.

Also, to help debugging, please at AdoShowError, add procname(2) to 7:

Code: Select all  Expand view  RUN

FUNCTION ADOSHOWERROR( oCn, lSilent )

   LOCAL nErr, oErr, cErr

   DEFAULT oCn TO oConnection
   DEFAULT lSilent TO .F.

   IF ( nErr := oCn:Errors:Count ) > 0
      oErr  := oCn:Errors( nErr - 1 )
      IF ! lSilent
         WITH OBJECT oErr
            cErr     := oErr:Description
            cErr     += CRLF + 'Source       : ' + oErr:Source
            cErr     += CRLF + 'NativeError  : ' + cValToChar( oErr:NativeError )
            cErr     += CRLF + 'Error Source : ' + oErr:Source
            cErr     += CRLF + 'Sql State    : ' + oErr:SQLState
            cErr     += CRLF + REPLICATE( '-', 50 )
            cErr     += CRLF + PROCNAME( 1 ) + "( " + cValToChar( PROCLINE( 1 ) ) + " )"
            cErr     += CRLF + PROCNAME( 2 ) + "( " + cValToChar( PROCLINE( 2 ) ) + " )"
            cErr     += CRLF + PROCNAME( 3 ) + "( " + cValToChar( PROCLINE( 3 ) ) + " )"
            cErr     += CRLF + PROCNAME( 4 ) + "( " + cValToChar( PROCLINE( 4 ) ) + " )"
            cErr     += CRLF + PROCNAME( 5 ) + "( " + cValToChar( PROCLINE( 5 ) ) + " )"
            cErr     += CRLF + PROCNAME( 6 ) + "( " + cValToChar( PROCLINE( 6 ) ) + " )"
            cErr     += CRLF + PROCNAME( 7 ) + "( " + cValToChar( PROCLINE( 7 ) ) + " )"

Fix for HBRECNO creating:

   ADOCONNECT( nWA, aOpenInfo )

   /*

Lucas,

Antonio,

With the version you just send me, there are some bugs so far:

At, ADOFINDREC(), oRecordSet:AbsolutePosition := IF( oRS:AbsolutePosition == adPosEOF, oRS:RecordCount() + 1, oRS:AbsolutePosition ) is failing, as IF( oRS:AbsolutePosition == adPosEOF, oRS:RecordCount() + 1, oRS:AbsolutePosition ) its giving -1, which is not possible.

HBRECNO is not created by default. Also, the code at ADO_OPEN is not being proccessed to add it.

I suggested to simple add it to ADOCREATE(), which is the easiest way as explained before.

Also, to help debugging, please at AdoShowError, add procname(2) to 7:

HBRECNO or equivalent is missing. Im going to take out that code and it simply errors stating missing field...

AbsolutePosition Positionenum

Constant
Value
Description
adPosBOF
-2
Indicates that the current record pointer is at BOF (that is, the BOF property is True).
adPosEOF
-3
Indicates that the current record pointer is at EOF (that is, the EOF property is True).
adPosUnknown
-1
Indicates that the Recordset is empty, the current position is unknown, or the provider does not support the AbsolutePage or AbsolutePosition property.

Please also check your MySql ODBC driver params.

ADD COLUMN I need to have it in ADO_OPEN. Our client upload the tables with copy to and tehn he expects when opening it to have the field created.
Ill put it also in ADO_CREATE

[lucasdebeltran]

Antonio,

With my previous code for HBRECNO, ADOFINDREC() does not fail.


Thank you.

[lucasdebeltran]

Antonio,

DbAppend(, ADO_APPEND(), fails with dates here:

Code: Select all  Expand view  RUN

           AADD( aVals, HB_DECODE( aStruct[ n, 2 ], 'C', Space( aStruct[ n, 3 ] ), 'D', CToD( '' ), 'L', .f., ;
                 'M', "", 'm', "", '+', 0, ;
                 'N', If( aStruct[ n, 3 ] == 0, 0, Val( "0." + Replicate( '0', aStruct[ n, 3 ] ) ) ), ;
                 'T', CTOT( '' ), '' ) )
 

It does not support an empty CTDOD().

[lucasdebeltran]

Antonio,

I asked about empty dates at append blank.

Also, SET FILTER does not suport values, i.e:

Code: Select all  Expand view  RUN

SET FILTER TO LUCAS->NAME == cName
 

Thank you.

Seems less to finish ADORDD.

[AHF]

Lucas,

It does not support an empty CTDOD().

How can it work here like that? adordd its prepared to consider 31/12/1899 as empty date.
We place 31/12/1899?

With my previous code for HBRECNO, ADOFINDREC() does not fail.

Table is the same ? Here that version its working.

There must be something wrong with your config. Here all its working.

ADO_OPEN it inserts field set to be used as recno as first field primary key.

Do you have SET ADO DEFAULT RECNO FIELD TO .. defined?

[AHF]

Lucas,

I asked about empty dates at append blank.

Please explain.

Also, SET FILTER does not suport values, i.e:

Code:

SET FILTER TO LUCAS->NAME == cName

Thats what I was speaking about. All vars must be evaluated before sent to ado filter once they are out of scope there.
In order to be 100 % compatible with standard syntax we must evaluate the filter condition ourselves and build a "faik" recordset.

Again please check your config because here all your mentioned points are working.

[lucasdebeltran]

Antonio,

About filtering, is not possible at SqlTranslate() to evalutate cName, so as to get its value and build the filter?.

[lucasdebeltran]

Antonio,

At ADOAPPEND(), and using Mr. Nages advice, this is the proper fix:

Code: Select all  Expand view  RUN

            AADD( aVals, HB_DECODE( aStruct[ n, 2 ], 'C', Space( aStruct[ n, 3 ] ), 'D', AdoNull(), 'L', .f., ;
                 'M', "", 'm', "", '+', 0, ;
                 'N', If( aStruct[ n, 3 ] == 0, 0, Val( "0." + Replicate( '0', aStruct[ n, 3 ] ) ) ), ;
                 'T', AdoNull(), '' ) )

Antonio,

I get this error:

Error description: (DOS Error -2147352567) WINOLE/1007 No se puede encontrar la fila para su actualización: algunos valores han cambiado desde la última vez que se leyó. (0x80040E38): Microsoft Cursor Engine

This is my code:

REPLACE FACTURAS->NOMBRE WITH CLIENTES->NOMBRE
.... and so one


The real cause:

Field lengh for FACTURAS nombre is 34, but in CLIENTES is 50.

[lucasdebeltran]

But current NAME is LUCAS DE BELTRAN, not 50 or 34 chars.
