Splitting multiple (pl/sql)/sql statements

Question

Hi,
I am trying to build a pl/sql editor on my website. Everything works fine for single commands, but the way it is going to be used the user can enter multiple commands/blocks on the text editor to execute and in which case the OracleCommand throws an error. I know I can wrap the multiple commands in a block but when I do an ExecuteNonQuery it returns -1 instead of how many rows are changed. For example, the following commands could be entered:
INSERT INTO someTable(col1, col2, col3) VALUES (val1, val2, val3);
INSERT INTO someTable(col1, col2, col3) VALUES (val4, val5, val6);
BEGIN
do something;
END;
And when the user clicks run I have two choices that I know of. I could wrap all the text in BEGIN and END; but as stated above it then does not return the correct row count, or I could try and split up the commands/blocks, which looks like thats what I'm going to have to do. So my question is is there an easy way, or hard anyway, to split multiple statements into individual statements? What is really giving me the problems are the annonymous blocks, so if there is an easy what to tell when an annonymous block is complete that would be very helpful.
Thanks in advance

So far everything you have said is correct. Sounds like things are working exactly as they are documented to work.
Per the Oracle Data Provider for .NET Developer's Guide
http://docs.oracle.com/cd/B19306_01/win.102/b14307/OracleCommandClass.htm
>
OracleCommand Class
An OracleCommand object represents a SQL command, a stored procedure, or a table name. The OracleCommand object is responsible for formulating the request and passing it to the database. If results are returned, OracleCommand is responsible for returning results as an OracleDataReader, a .NET XmlReader, a .NET Stream, a scalar value, or as output parameters.

Note the 'a SQL command, a stored procedure, or a table name'. Multiple commands/blocks don't fall into any of those categories so, of course, you get an error.
And in the same document page
>
ExecuteNonQuery returns the number of rows affected, for the following:
•If the command is UPDATE, INSERT, or DELETE and the XmlCommandType property is set to OracleXmlCommandType.None.
•If the XmlCommandType property is set to OracleXmlCommandType.Insert, OracleXmlCommandType.Update, OracleXmlCommandType.Delete.
For all other types of statements, the return value is -1.

Your 'block' is not an UPDATE, INSERT or DELETE, etc so, as the doc says, 'For all other types of statements, the return value is -1.
It is YOUR responsibility to submit the individual statements and capture the results of each one.
