This chapter describes the data types and expressions that Dynamic Server and Extended Parallel Server support. These fundamental syntax segments can appear in data definition language (DDL) and data manipulation language (DML) statements, and in other types of SQL statements. Some SPL statements can also specify data types or expressions. You can use these features of a relational or object-relational database in various contexts, such as to define the schema of a table, to specify the signature and arguments of a routine, or to represent or calculate specific data values.
