Thank for your reply Wayne.
You know, I was testing it, but I have other problem the suject is that the field that I`m adding due to this no get all the information that I put it there.
This is the code:

SELECT CTOD(SUBSTR(STR(fechlo,8,0),7,2)+"/"+SUBSTR(STR(fechlo,8,0),5,2)+"/"+SUBSTR(STR(fechlo,8,0),1,4)) AS fecha,;
iif(alltr(proglo)#"BODPJIDH","Pers. Natural","Pers. Juridica") AS tipo,;
"Hist. Conexiones" AS indicador,;
COUNT(Conexiones_historico.fechlo) AS transxdia;
FROM "datos!conexiones historico" Conexiones_historico;
GROUP BY Conexiones_historico.fechlo, Conexiones_historico.proglo;
INTO TABLE dbfstmp\conhist.dbf

When I check out the information in the fields indicador the information appears cut, I mean "Pers. Juridic".
I have change the posicion of the information, put just "Juridica", the logic validation, but any thing of this resolve the problem.
Do you know, where is the mistake.?
TIA
