SQL Server Data Types Numeric data types: Can be anything from very small to extremely large numbers. Also included are specific formats such as monetary amounts, float point numbers, numbers with a known number of decimal points, whole numbers, and so on. Date and time data types: Allows the direct input of date and time values. This is usually in a default format, such as mm/dd/yyyy hh:mm, or something similar. String data types: Can be fixed length strings, variable length strings, or even very large text objects. Text objects may or may not be stored in binary format. Strings normally accept alphanumeric data. Alphanumeric characters are letters, numbers, and special characters (anything on your keyboard that is not a letter or a number). Binary data types: Typically used to store large objects, including images, sound files, video, even very large textual values like documents. SQL Server 2005 allows storage of similarly related Microsoft product types, such as directl
