buildGroupConcatField ( $delim, $table, $field, $conds='', $join_conds=[]) | |

MS SQL requires specifying the escape character used in a LIKE query or using Square brackets to surround characters that are to be escaped http://msdn.microsoft.com/en-us/library/ms179859.aspx Here we take the Specify-Escape-Character approach since it's less invasive, renders a query that is closer to other DB's and better at handling square bracket escaping. | |

$table, | |||

) |
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.
