  How to Detect Similar Strings Where one may contain a spelling error

  Aug 23, 2018 04:48 AM|RobertH3|LINK

  I wish to be able to detect if someone is entering data into a field that may be the same but one may contain a spelling error or be off by one word.

  My table is a list of tasks

  A task in the database may be "Clean Bathroom"

  If an admin wants to enter a new task for selection and enters "Clean Bath Room" or "Clean Bath-Room" or they enter "Clean Baathroom"

  This is for a Stored Procedure

  Hi RobertH3,

  You can try to use Soundex() or Difference() to get the desired result.

  You can refer example below.

  Data in table.

  

  Query:

  SELECT *
  FROM comp_test
  WHERE SOUNDEX('Clean Bathroom') = SOUNDEX(col1)
  
  OR
  
  SELECT *
  FROM comp_test
  WHERE DIFFERENCE(col1, 'Clean Bathroom') >= 3

  Output:

  

  Reference:

  SOUNDEX (Transact-SQL)

  DIFFERENCE (Transact-SQL)

  Regards

  Deepak
