Thanks for your assistance, I may not have asked the question quite clear enough : I don't know how many columns are being selected, nor what these columns are, so is there a way to get this information?

e.g. your statement
dbms_sql.define_column(source_cursor, 1, vValue,2000);

is explicitly defining the 1st column of the results of the select statement. I need to repeat this 'n' times (but don't know what value 'n' will be) and identify the column name.

ALTERNATIVELY, i could have completely misunderstood your response :)

Thanks
