Question

I’m trying to run a query from a .NET page but I seem to having some problems with having multiple queries.

My query is similar to this

SELECT * FROM table1; SELECT * from table2

But i seem to get an invalid character error when executing this from a .Net page. It runs fine in SQL developer but only fails when i put it in my .NET page.

I’ve added the BEGIN and END to the query as some websites suggest you need this to run multiple queries but then I get the following error

ORA-06550: line 1, column 7:
PLS-00428: an INTO clause is expected in this SELECT statement

Can anyone shed any light on this one?

Thanks in advance!

EDIT

Here’s some code

        query = conn.CreateCommand()

        query.CommandText = "SELECT * from table1; SELECT * FROM table2;"

        DataSet = New DataSet()
        DataAdapter = New DataAdapter(query)
        DataAdapter.Fill(DataSet)

        datagrid1.DataSource = DataSet.Tables(0)
        datagrid1.DataBind()

        lbl1.Text = DataSet.Tables(1).Rows(0).Item("column1").ToString()

If you want to pull from 2 tables and get a DataSet that you can fill into a DataAdapter, then you need to use one of the following approaches:

1. join the 2 tables together (may or may not be possible depending on your tables)
2. union the 2 tables (this may or may not be applicable to your scenario)
3. write a stored procedure which creates whatever result you need and returns it in a ref cursor. You can read about how to do that here.

You’re not going to be able to just run 2 SQL statements like that and get any meaningful result into a DataSet.
