PARSENAME Enhancement

By Peter Larsson,

The ParseName function is very useful for getting parts out of a string of characters between delimiters. But a limitiation is that you only can get four parts out, and the function only accepts dots as delimiters.

The function I have written below overcomes that limitations, and add a new feature to enable "from left" and "from right" character extraction.


Example code

declare    @var varchar(200)

select    @var = 'a.ab.abc.abcd.abcde'

select    @var,
    dbo.fnParseString(4, '.', @var),
    dbo.fnParseString(-4, '.', @var)
