FIX: Incorrect results when you use a LIKE operator and an "ss" wildcard in SQL Server 2014 or 2016

Applies to: SQL Server 2014 DeveloperSQL Server 2014 DeveloperSQL Server 2014 Enterprise

Symptoms


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.

Notes 
  • 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.
