Convert Integer to String in SQL Server

A very frequently asked question is how to convert an Integer to String in SQL Server. Here are 3 different ways of doing the same task:

DECLARE @i int
SET @i=98235

--Method 1 : Use CAST function
SELECT CAST(@i as varchar(10))

--Method 2 : Use CONVERT function
SELECT CONVERT(varchar(10),@i)

--Method 3 : Use STR function
SELECT LTRIM(STR(@i,10))

All of them result in the same output
