 A constant, also known as a literal or a scalar value, is a symbol that represents a specific data value. The format of a constant depends on the data type of the value it represents.
 
+> [!NOTE]
+> The term *constant* in application development and the concept of a *constant* in Transact-SQL (T-SQL) are not the same. There is no specific way to set a global static value in T-SQL. Constants in T-SQL are the equivalent of string literal values.

 ## Character string constants
 
 Character string constants are enclosed in single quotation marks and include alphanumeric characters (`a`-`z`, `A`-`Z`, and `0`-`9`) and special characters, such as exclamation point (`!`), at sign (`@`), and number sign (`#`). Character string constants are assigned the default collation of the current database. If the COLLATE clause is used, the conversion to the database default code page still happens before the conversion to the collation specified by the COLLATE clause. Character strings typed by users are evaluated through the code page of the computer and are translated to the database default code page if it is required.
