問題文

A weekly report truncates each date to the start of its week and the buckets begin on a different weekday on two servers. The statement is identical on both. Which cause fits and which change makes it stable?

選択肢

  1. The starting day of the week comes from a language setting so setting the date language of the session makes the buckets stable across the two servers.
  2. A character value of zero length is rejected by the column so the load must have failed and those rows never reached the table.
  3. The starting day of the week comes from a territory setting so using the format element that follows the international standard makes the buckets stable.
  4. The starting day of the week comes from the first row that the query reads so ordering the rows before the truncation makes the buckets stable.
