Long sql query

Hi everybody. I need to perform a long sql select command to retrieva some
data from mysql. The code goes like this:

set.size 140 %querySelect "select autoriza,barra from consumos where
nro_socio='" %nro_socio "' and COD_PRESTA='" %cod_presta "' and
FECH_ORDEN<='" %fech_orden "' and FECH_ORDEN >= '2003-04-01'"

The problem is that the sql command gets truncated like this:

select autoriza,barra from consumos where nro_socio='131850330500' and
COD_PRESTA='1420101' and FECH_ORDEN<='20

Does anybody know how to deal with this problem?
Thanks a lot !
