MSSQL:aktualizujte odpovídající řádky z nahraného souboru

Toto je mnohem snazší přístup k datům odděleným potrubím. Data podobná tabulce najdete v #temp2. Od této chvíle by mělo být snadné UPDATE ,INSERT nebo MERGE vaše data do cíle.

Pozor:Mohl jsem jen odhadnout význam vašich sloupců, takže názvy sloupců mohou být nesmyslné...

CREATE TABLE #temp1(WHOLEROW VARCHAR(8000));
INSERT INTO #temp1 VALUES
