C# parameterized queries for Oracle – serious & dangerous bug!

by

This is not a bug but explicitly mentioned in Oracle ODP.Net documentation. In a OracleCommand class the parameters are bound by position as default. If you want to bind by name then set the property cmd.BindByName = true; explicitly.

Reference to Oracle documentation.
