Build a GROUP_CONCAT or equivalent statement for a query.
MS SQL doesn't have GROUP_CONCAT so we emulate it with other stuff (and boy is it nasty)
This is useful for combining a field for several rows into a single string. NULL values will not appear in the output, duplicated values will appear, and the resulting delimiter-separated values have no defined sort order. Code using the results may need to use the PHP unique() or sort() methods.
