As I known sqlind is for know if a column allow null values and not for
know if a column value is null.

With this :

(row[i] == null ? -1 : 0)

if row[i] is not null sqlind will indicate that column don´t allow null
values and this is no true the column can accept null values.

I solved it adding isc_info_sql_null_ind to sql_prepare_info in
isc_dsql_prepare ( and in isc_dsql_describe and in
isc_dsql_describe_bind ), and modifiying ParseTruncSqlInfo for get
isc_info_sql_null_ind value.

This allows to get null indicator without make a fetch.
