忘備録

Last updated at Posted at 2021-02-19

とりあえずまとめる

  • SQLまわり
    • null同士は比較しない。
      • null = null → false
      • coalesceして比較する
    • utf8をbulk insert したい
      • rowterminator = '0x0a'
    • Accessを使おうとしてちょっと困ったところ
      • with句使えない
      • 3つ以上のテーブルをjoinするときは括弧でくくる
        • from ((a join b) join c)join d
      • case が使えない
        • iif(a=b,真の時,偽の時)
      • 数字、記号の入ったテーブル名はくくる
        • from [a1] join [b+]
