I have an SQL insert in SQL-Server that looks like this:
  INSERT INTO Configuration.Localization ( languageid, localizationkey, localizationvalue)  VALUES
(lang,'core.common.altered','(altered)'),
(lang,'core.common.cancel','Cancel'),
(lang,'core.common.ordernumber','Order number'),
(lang,'core.common.prefix','Prefix') ...
and so on.
How do I modify this query to use UPDATE instead of insert (similarly to "ON DUPLICATE KEY UPDATE" in MySQL), while keeping the overall structure of the query (I want it still to be one operator, not many).
Preferably I would like to be specific in the query, that UPDATE must happen if lang and localizationkey both match.
