error: Cursor not returned from query

P: n/a
I'm a really beginner about sql2000.
During my test I have created the following query. It's works ok until I
do't add the code included in section A, when I add it the i obtain the
error: Cursor not returned from query
Anyone can help me?

Thanks Carlo M.

set nocount on

IF OBJECT_ID('storico_big') IS NULL --- section A begin
create table storico_big( data datetime,
bcarrier varchar(20),
bda CHAR(30),
bzone char(50),
bdur int) ;
insert into storico_big --- section A
end

select top 10000
adetdate,bcarrier,bda,bzone,bdur
from pp_cdr (nolock)
where
adetdate < :data_fin and adetdate > :data_in order by adetdate
set nocount off

------ end of query

Apparently you are using some environment unknown to me. At least I
don't recognize the message.
IF OBJECT_ID('storico_big') IS NULL --- section A begin
create table storico_big( data datetime,
bcarrier varchar(20),
bda CHAR(30),
bzone char(50),
bdur int) ;

end


Since there are several apparent syntax errors here, it would have been nice
if you environment had returned the errors from SQL Server, rather than
bitching about the missing cursor.

It can be a good to run the query from Query Analyzer to get better
error diagnostics.

I don't really want to suggest a correction, because I can't understand
what you are trying to do. It appears that in the same batch that you first
want to create a table, insert into it, and then select data from another
table.

Possibly you want to insert the data from the SELECT statement into
storico_big, but in such case you should

1) get rid of that extraneous end
2) add an explicit column list to the INSERT statement.

However, I have a feeling that if you insert data into the table, the
client environment will still complain about a missing cursor...

I would suspect that it's some data layer (such as ADO, ADO.NET, DAO,
etc), which has at least two different methods of performing work in
the database - one for performing data retrieval and another (possibly
on another object, if the layer is object oriented) which allows data
manipulation.

For instance, ADO.NET has ExecuteReader and ExecuteNonQuery methods on
it's command object.

Obviously IWZFIV is not using ADO .Net. ADO .Net does work with cursors
at all, as far as a I know. A more substantial clue is the condition:

adetdate < :data_fin and adetdate > :data_in order by adetdate

Apparently IWZFIV is using some form of embedded SQL.

Anyway, I would not really describe ADO .Net as providing different methods
for different purposes. If all you want is minimalism, you can do every-
thing with ExecuteReader. The other methods, ExecuteNonQuery, ExecuteScalar
and DataAdapter.Fill can be seen as convenience methods implemented on
top of ExecuteReader. (OK, this is not really true. There are some
fine differences when there are multiple error messages and result sets
interleaved.)
