Return value from a stored proc on error

Question

I have an sp in SQL Server that when errors returns -4

What does -4 mean? Is there a table somewhere explaining what the possible return values are?

I'm not sure there's a way to know this without asking the SQL Server devs. It's something lower level than your stored proc evaluating what you're sending it and generating that return code. Unless you've specifically got a RETURN -4 in your code, it's coming from the SQL parser probably.
