GSList *
gda_entity_get_fields (GdaEntity *iface
);
Get a new list containing all the GdaEntityField objects held within the object implementing the GdaEntity interface.
The returned list nodes are in the order in which the fields are within the entity.
gint
gda_entity_get_n_fields (GdaEntity *iface
);
Get the number of fields in iface
GdaEntityField * gda_entity_get_field_by_name (GdaEntity *iface
,const gchar *name
);
Get a GdaEntityField using its name. The notion of "field name" is the
string returned by gda_entity_field_get_name()
on each of the fields composing iface
.
However, if that definition does not return any field, then each particular
implementation of iface
may try to give an extra definition to the notion of
"field name".
For instance, in the case of the GdaQuery object, the gda_entity_field_get_name()
is used
as a first try to find a field, and if that fails, then the object tries to find
fields from their SQL naming.
In the case where there can be more than one field with the same name (depending on
iface
's implementation), then the returned value is NULL
.
the requested GdaEntityField or NULL
if the field cannot be found, or if
more than one field has been found.

gint gda_entity_get_field_index (GdaEntity *iface
,GdaEntityField *field

Get the position of the field in the given entity. Positions start at 0.
