Použijte DATENAME a zabalte logiku do funkce, nikoli do uloženého procesu
declare @myTime as DateTime
set @myTime = GETDATE()
select @myTime
select DATENAME(day, @myTime) + SUBSTRING(UPPER(DATENAME(month, @myTime)), 0,4)
Vrátí "14OCT"
Pokud je to možné, při práci s daty nepoužívejte žádné operace založené na znacích / řetězcích. Jsou numerické (plovoucí) a výkon utrpí těmito převody datových typů.

/*Getting Parts of a DateTime*/
--//gets the date only, 20x faster than using Convert/Cast to varchar
--//this has been especially useful for JOINS
SELECT (CAST(FLOOR(CAST(GETDATE() as FLOAT)) AS DateTime))
--//gets the time only (date portion is '1900-01-01' and is considered the "0 time" of dates in MSSQL, even with the datatype min value of 01/01/1753.

/*Current Day*/
--//now
