Assume that you run a query that uses a LIKE operator (pattern matching) together with "ss" as a wildcard character to find approximate matches. If the wildcard character is at the end of the statement, the result may not contain all the approximate matches.


  • The LIKE operator supports both ASCII and Unicode pattern matching. This issue does not occur if the data is stored in Unicode data types.

  • This issue is known to occur in the German language, where the "ss" characters can be regarded as the same as the "ß" character.
