Hi,

I was trying to get the records of select statement inside the procedure of Oracle (not sql server), the image is attached and then get the data in say Data Reader like

DataReader dr=ObjOracleHelper.ExecuteNonQuery("procedureName", oPara, CommandType.StoredProcedure);

but the procedure return error and don't allow me this. I don't want to use the query in the Data Access Layer.

The select statement return around 100 records.

Can anyone help!

Thanks

Oracle does not support that, you got to use INTO or use a variable:
oracle-select-statement-in-if-condition

BUT I have to return 100 records having 10 columns from Oracle Proecedure. There must be some way out!

By using INTO variable I can not select/retrieve say 100 records from the table.

you can declare new type which consists of the fields in your select statement.
for instance,
the following won't work as explained:
if(lastid != 0 then
select a,b,c,d from table
end if;

Open in new window

so what you wanna do is to declare new type:
DECLARE
  TYPE SomeNewType IS RECORD (
    tmp_a table.a%TYPE,
    tmp_b table.b%TYPE,
    tmp_c table.b%TYPE
  );
  recNewType SomeNewType;

Open in new window

and use it in your if expression:
if(lastid != 0 then
SELECT a, b,c  INTO recNewType 
  FROM table
end if;

Open in new window

check here for example:
SELECT INTO Assigns Values to Record Variable

must it be a stored procedure? why not use a table function?

but: perhaps I'm missing the point

You can declare a record and use an associative array but I would suggest you return a ref cursor.

There are a ton of examples out there if you look around:

Also, if you aren't using ODP.Net, I strongly encourage you to start.
