Is SQL case insensitive?
SQL Server is, by default case insensitive; however, it is possible to create a case sensitive SQL Server database and even to make specific table columns case sensitive. The way to determine a database or database object is by checking its “COLLATION” property and look for “CI” or “CS” in the result.
Why is SQL Server case insensitive?
Most SQL Server installations are installed with the default collation which is case insensitive. This means that SQL Server ignores the case of the characters and treats the string '1 Summer Way' equal to the string '1 summer way'.
