  SQL Query

  Jul 16, 2018 02:29 AM|ThisIsYusuf|LINK

  Hi

  I have two tables: dictionary table that contains word field, 
  and Spell that is an empty table and contain correct and wrong fields
  I want to generate a spelling dictionary for words that start with the letter C 
  
  

  +----+-------------+-----------+
  | id | CorrectWord | WrongWord |
  +----+-------------+-----------+
  | 1  | camera      | kamera    |
  +----+-------------+-----------+
  | 2  | car         | kar       |
  +----+-------------+-----------+
  | 3  | card        | kard      |
  +----+-------------+-----------+

  I'm looking for something similar to this code, in T-sql language.

  Thanks in advance

  
  Sql = "Select word FROM dictionary WHERE word Like ""C%""" 'Words that start with C
  While rdr.Read() 'for each row
    CorrectWord = rdr("word") 'e.g. Cat
    Wrongword = Replace_First_Letter_With_K("word") 'e.g. Kat
      If RowCount("select * from dictionary WHERE word = " & Wrongword) = 0 Then 'If 'Kat' does not exist in the 'Dictionary' table
        InsertCommand = "INSERT INTO spell (correct, wrong) VALUES(""{0}"", ""{1}"")", CorrectWord, WrongWord
        Insert()
    End If
  End While

  Hi ThisIsYusuf ,

  I can see that you are trying to create a dictionary for words and you are trying to storing correct words and wrong words.

  Here, I think that you not need to store wrong words, because combination of wrong words has no any limit and user can input anything.

  Also it is not a good practice to store incorrect words in your dictionary.

  I suggest you to only store the correct words and use 'Soundex' and 'difference' function to find the correct words from your table.

  For Example, I store below data in my table.

  

  Fire some queries to find correct word from table.

  SELECT word
  FROM speliing_data
  WHERE SOUNDEX('card') like SOUNDEX(word)
  
  
  
  SELECT * FROM speliing_data
  WHERE DIFFERENCE(word,'kamera') >= 3
  
  SELECT * FROM speliing_data
  WHERE DIFFERENCE(word,'kar') >= 3
  
  SELECT * FROM speliing_data
  WHERE DIFFERENCE(word,'kard') >= 3

  Output:

  

  Reference:

  SOUNDEX (Transact-SQL)

  DIFFERENCE (Transact-SQL)

  You can find more examples online to get detailed idea, Based on that you can again think about your table design to store only correct words.

  Regards

  Deepak
