What's the best practice of naming stored procedure for t-sql?

Question

I have worked with several big databases and the names of stored procedures were very different:

SP_PrefixXXX
PrefixYyyXxx
Prefix: Rep, Act

Answer 1

Im not a pro but i like this way

Prefix of application = XY; View = v; Stored Procedure = p; Function = f

Table: XY_Name
View: vXY_Name
Procedure: sXY_Name
Function: fXY_Name

What do you think ? I know some people use the two characters for identifying object type but one character is enough for most cases, right ?
