The present invention relates to systems and methods to generate stored procedure calling code. The invention includes system and methods that utilize annotation(s) included in a stored procedure. The annotations comprise attributes that indicate the intent to have stored procedure calling code generated. After the annotated stored procedure becomes available, the code is compiled and, optionally, checked for errors, and an intermediate definition with metadata is created. The definition is a stored procedure interface language (SPIL) file. The SPIL definition is then utilized to generate high-level, stored procedure calling code, or class libraries. The high level code can then be employed within an application to invoke the stored procedure.
