各単語の "like"クエリーのための単語の使用

Question

私は、単語のセットをループしたり、必要に応じてDOBを検索しながら各単語の特定のフィールドで同様の条件を実行したりするのに、

誰もがWhileループの必要性の中でこれを行う方法を見ることができますか？私はSTRING_SPLITを使ってこれを行う方法を見つけられませんでしたが、これを使ってLIKEを追加することはできません。

SELECT TOP 1 WITH TIES 
    ClientID, 
    FirstName, 
    LastName, 
    VerificationCode, 
    DOB 
FROM 
    (
    SELECT 
     1 RowPriority, 
     ClientID, 
     FirstName, 
     LastName, 
     VerificationCode, 
     DOB 
    FROM Client c 
    WHERE EXISTS(
       SELECT * 
       FROM #SearchWords s 
       WHERE (c.FirstName LIKE CONCAT('%',s.Word,'%')) 
       OR (c.LastName LIKE CONCAT('%',s.Word,'%')) 
       OR (c.VerificationCode LIKE CONCAT('%',s.Word,'%')) 
      ) 
     AND DOB BETWEEN ISNULL(@LowerDate,DOB) AND ISNULL(@UpperDate,DOB) 

    UNION ALL 

    SELECT 
     2 RowPriority, 
     ClientID, 
     FirstName, 
     LastName, 
     VerificationCode, 
     DOB 
    FROM Client c 
    WHERE DOB BETWEEN ISNULL(@LowerDate,DOB) AND ISNULL(@UpperDate,DOB) 
) q 
ORDER BY RowPriority 

つ以上に一時的なテーブルずに次のクエリ

SELECT 
    ClientID, 
    FirstName, 
    LastName, 
    VerificationCode, 
    DOB 
FROM Client c 
WHERE EXISTS(
      SELECT * 
      FROM #SearchWords s 
      WHERE (c.FirstName LIKE CONCAT('%',s.Word,'%')) 
      OR (c.LastName LIKE CONCAT('%',s.Word,'%')) 
      OR (c.VerificationCode LIKE CONCAT('%',s.Word,'%')) 
     ) 
    AND DOB BETWEEN ISNULL(@LowerDate,DOB) AND ISNULL(@UpperDate,DOB)
