error in incremental load

[#1]

Hello,

I'm trying to implement incremental loading of data.  To start, I took a simple table in one of our SQL-databases.I'm getting errors when reloading the data
The Code :

SET 
 ThousandSep  ='.';
SET  DecimalSep  =',';
SET  MoneyThousandSep  ='.';
SET  MoneyDecimalSep  =',';
SET  MoneyFormat  ='€ #.##0,00;€ -#.##0,00';
SET  TimeFormat  ='h:mm:ss';
SET  DateFormat  ='D/MM/YYYY';
SET TimestampFormat='D/MM/YYYY h:mm:ss[.fff]';
SET MonthNames='jan;feb;mrt;apr;mei;jun;jul;aug;sep;okt;nov;dec';
SET DayNames='ma;di;wo;do;vr;za;zo';

SET vDB='Dehaan.dbo.Personel';

SET vQvdFile='VTW.qvd';
SET vTableName='VTW';
SET vPK='PersonelId';

LET vQvdExists = if(FileSize('$(vQvdFile)') > 0, -1, 0);

IF $(vQvdExists) THEN
     maxdateTab:
     LOAD max(VTW.ModifyDate) as maxdate
          FROM $(vQvdFile) (qvd);
     LET vIncrementalExpression = 'WHERE ModifyDate >=' & date(peek('maxdate'),'yyyy-mm-dd');
     DROP table maxdateTab;
ELSE 
     LET vIncrementalExpression = '';
END IF

//==========================================================================================
// Data Load
//==========================================================================================

$(vTableName):
ODBC CONNECT TO BRP (UserId is sa, Password is 9999);
LOAD 
    Email AS VTW.Email,
    FirstName AS VTW.Voornaam,
    ModifyDate AS VTW.ModifyDate,
    Name,
    PersonelId,
    PersonelPicture,
    Picture,
    SearchName,
    if(SearchName='EBA','AAU',
          if((FirstName='Nathalie' OR FirstName='Nele' OR FirstName='Dan'),'SALMA',
          if((SearchName='PVP' OR SearchName='VDP'),'VDP',
          if(SearchName='PHU','PHU',
          if(SearchName='AHE','AHE',
          if(SearchName='AAU','AAU',
          if(SearchName='CVE','CVE',
          if(SearchName='KVE','KVE',
          if(SearchName='LSA','VDP',
          if(SearchName='RVDW','PDE',
          if(SearchName='SALMA','SALMA',
          if(SearchName='Salma','SALMA',
          if(SearchName='salma','SALMA',
          if(SearchName='Marke','MARKE',
          if(SearchName='RRI','RRI',
          if(SearchName='PDE','PDE',
          if(SearchName='WSCHO','WSC'))))))))))))))))) AS VTW;
SQL SELECT * FROM $(vDB) $(vIncrementalExpression);

//==========================================================================================
// Incremental Load
//==========================================================================================

ODBC CONNECT TO BRP (UserId is sa, Password is 9999);
IF $(vQvdExists) THEN
     Concatenate ($(vTableName))     LOAD * FROM $(vQvdFile) (qvd)
     WHERE NOT exists($(vPK));
END IF

INNER JOIN ($(vTableName))
LOAD $(vPK) FROM Dehaan.dbo.Personel;

STORE $(vTableName) INTO $(vQvdFile); 

Yes, password sa is 'changed'.
