It would be nice if we only had to sortīy pointer, but we need to support picking, say, the Now, the first function, which uses STRING_SPLIT, To support longer delimiters without significant refactoring. In a couple of spots, it will be non-trivial My current requirements), and in some cases this also avoids calculations that STRING_SPLIT's limitation (and, conveniently, We're also restricting the delimiter length to 1, both to match.Table-valued function whose only job is to apply the hint). Hint on the outer query that references the function (or create a wrapper multi-statement OPTION (MAXRECURSION) hint so, if we have stringsĬontaining more than 100 elements and decide for some reason to use a recursiveĬTE solution, we will need to apply a MAXRECURSION We can't avoid this inside an inline TVF using an So we don't have to worry about recursion exhaustion in the recursiveĬTE solution. We're only creating strings with a maximum number of 100 elements,.Skew or code changes required due to LOBs if you need to support strings exceedingĤ,000 characters, you'll have to change the functions accordingly We're limiting the input to 4,000 characters to avoid any performance.And let's review some notes about the functions we'll be creating
