Обсуждение: INSERT or UPDATE
Hello I have an XML file, which i must import into the database. I transform this XML File with xslt to sql INSERTS. But there is also the possibility, that one row is available. Means that i need an UPDATE instead of the INSERT. Is it in SQL possible to decide if there is an UPDATE or an INSERT or must i program something with PHP for example? Thanks Andreas

You can use a own function for this, see http://www.postgresql.org/docs/current/static/plpgsql-control-structures.html#PLPGSQL-ERROR-TRAPPING Example 38-1.
