Data definition phrases, also referred to as data description phrases, are used in SQL statements to define how to store data in the columns of a table, how to present the data in the results of queries, and whether to apply column-level integrity constraints.

You can also use data definition phrases in expressions to convert data to another type or modify data attributes.
