2          e

2          f

3               g          h

I tried this:

temp1:

generic load * resident original;

result:

load distinct identificacion resident original;

drop table original;

FOR i = 0 to NoOfTables()

TableList:

LOAD TableName($(i)) as Tablename AUTOGENERATE 1

WHERE WildMatch(TableName($(i)), 'temp1.*');

NEXT i

FOR i = 1 to FieldValueCount('Tablename')

LET vTable = FieldValue('Tablename', $(i));

LEFT JOIN (result) LOAD * RESIDENT $(vTable);

DROP TABLE $(vTable);

NEXT i

drop table TableList;

but it is too slow i have arround 800.000 telephones..

Carlos,

Maybe I don't understand your question correctly.  Do you need a table in the data model with 4 fields called -

id, telefono1, telefono2, and telefono3?  Do you need a straight table or pivot table in the layout with those columns?


If you just need to show those columns in a pivot table, then the NewTable in my example above should work.

If you need a table in the data model, then you could use some more load script like this (please pardon any typos):

// create a new table that has the order of numero for each identificacion

NewTable:

Load

     identificacion,

     numero,

     If( identificacion = Peek( identificacion ), 1, Peek( telefono_seq ) + 1 ) as telefono_seq

Resident original

Order By

   id asc ;

// transpose the rows of NewTable to columns

ResultTable:

Load Distinct

     identificacion

Resident NewTable;

Left Join Load

     identificacion,

     numero as telefono1

Resident NewTable

Where

     telefono_seq = 1;

Left Join Load

     identificacion,

     numero as telefono2

Resident NewTable

Where

     telefono_seq = 2;

Left Join Load

     identificacion,

     numero as telefono3

Resident NewTable

Where

     telefono_seq = 3;


Drop Table NewTable;

You could calculate the values of telefono1, telefono2, telefono3 (another dimension) in the load script with something like this:

NewTable:

Load

     id,

     If( id = Peek( id ), 1, Peek( telefono_seq ) + 1 ) as telefono_seq

     Teléfono

Resident Original

Order By

     id asc ;


I hope that makes sense.

Or maybe something like this :

Temp :

LOAD * INLINE

[

id,Teléfono

1,a

1,b

1,c

2,e

2,f

3,g

3,h

](delimiter is ',');

Data :

Load

id ,

    subfield ( cTeléfono , ',' , 1 )  as [Teléfono 1] ,

    subfield ( cTeléfono , ',' , 2 )  as [Teléfono 2] ,

    subfield ( cTeléfono , ',' , 3 )  as [Teléfono 3]

;

Load

id,

    concat(Teléfono , ',') as cTeléfono

Resident Temp

group by id ;

Drop table Temp ;

I did this, with your advices

LIB CONNECT TO 'CRM PST';

Celulares:

     trim(identificacion)&'-'&trim(numero) as numero;

//      if(identificacion='',null(),identificacion) as identificacion,
