Re: The old inability to toggle/change/switch between ALTER PROCEDURE <---> CREATE PROCEDURE bug (or is it a feature?)

It seems you are confusing creating the proc with executing the proc. MV apparently displays (when
you select Edit or something similar), the proc code with an ALTER PROC in the beginning, assuming
that you want to modify the source code for the procedure.

Compare to developing a C app from an IDE. The IDE let you work with the source code. This is the
ALTER PROC part. When you open/edit or whatever the proc in VS, it reads the source code for the
proc from the system tables and replace the initial CREATE to ALTER assuming that you want to modify
the source code.

Executing the C code is different from compiling and linking it.

For the first URL you referred to, we never got a repro of what actually was happening. For the
second, we found a bug where the tool incorrectly not only changed CREATE PROC to ALTER PROC, but
also code *inside the proc* was changed such as CREATE TABLE changed to ALTER TABLE.

Also, I suggest you keep your source code in files, which allow you to version them (Source safe
etc). Or even look at Visual Studio for Database Professionals.
