    XMLWordPrintable

Details

    Description

      A multiple-table UPDATE first performs join operations, then it updates the matching rows.
      A multiple-table UPDATE returning a result set does the following:

      • first performs join operations
      • for each row of the result of the join it calculates some expressions over the columns of the join and forms from them a row of the returned result set
      • after this it updates the matching rows

      A multiple-table DELETE first performs join operations, then it deletes the matching rows.
