Null (SQL)
Null is a special marker used in Structured Query Language (SQL) to indicate that a data value does not exist in the database. Introduced by the creator of the relational database model, E. F. Codd, SQL Null serves to fulfill the requirement that all true relational database management systems (RDBMS) support a representation of ""missing information and inapplicable information"". Codd also introduced the use of the lowercase Greek omega (ω) symbol to represent Null in database theory. NULL is also an SQL reserved keyword used to identify the Null special marker.For people new to the subject, a good way to remember what null means is to remember that in terms of information, ""lack of a value"" is not the same thing as ""a value of zero""; similarly, ""lack of an answer"" is not the same thing as ""an answer of no"". For example, consider the question ""How many books does Juan own?"" The answer may be ""zero"" (we know that he owns none) or ""null"" (we do not know how many he owns, or doesn't own). In a database table, the column reporting this answer would start out with a value of null, and it would not be updated with ""zero"" until we have ascertained that Juan owns no books.SQL null is a state (unknown) and not a value. This usage is quite different from most programming languages, where null means not assigned to a particular instance.
