Why am I getting an ORA-01722 (invalid number)?

Question

I\'ve been using a parameterized query to insert values into an Oracle table, like so:

var q = \"insert into MyTable(Field1, Field2...) values(:Field1, :Field2..         


        

Answer 1

I have given answer credit already, but I think it's worth mentioning here exactly what the root of my problems was, in case anyone else finds this item while looking for an answer to their own problem.

The problem is that the C# implementation of parameterized queries for Oracle contains a serious and potentially dangerous bug - a real "pit in the public domain":

It doesn't matter what you name your parameters; they have to be added in the order in which they appear in the query.
