Have you ever tried to implicitly cast a larger data type into a smaller type (as far as the number of bits) through a plain old assignment? c# wont let you do it!

Its avoiding possibly dropping some of the 64 bits when assigning the value to 32 bits.

SQL Server allows you to set a case sensitive collation at both the database and column level but often you will need to do a case sensitive search when everything is case insensitive. Not to worry, you can set the collation directly in the query. /* To test string equality including case when the DB is not case sensitive you must include collation as part of the test as follows: */ declare @mystring1 varchar(10) declare @mystring2 varchar(10) set @mystring1 ='abc' set @mystring2 ='ABC' -- by default...
