REAL approximate numerical, mantissa precision 7 DECIMAL(P,S) Exact numerical, 'P' is precision value and 'S' is scale Precision 10 NUMERIC(P,S) Exact numerical (Same as DECIMAL) Precision P and scale value Precision P INTEGER Integer numerical (no decimal). Precision 5 INTEGER(P) or INT(P) Integer numerical (no decimal). Media Types General Data Types in SQL Data type Description SMALLINT Integer numerical (no decimal).The Oracle-supplied types, along withĬross-references to the documentation of their implementation Services needed for input-output, varied client-side access for newĭata types, and optimizations for data transferring between theĪpplication and the database. Oracle Database repeatedly allows the low-level infrastructure Working for these types can be implemented in C/C++, Java, or PL/
Interfaces for defining new types when the built-in orĪNSI-supported types are not satisfactory. Oracle-Supplied Types: Oracle offers SQL-based Types as the construction blocks for object types, which models theĬonfiguration and actions of data in applications. User-Defined Types: User-defined data typesĮmploy Oracle's built-in data types and few other user-defined data Scalar value of binary or character data. Unusual form of scalar data type which represents a considerable Holds an atomic value, whereas a non-scalar, which is also called a A data type is either scalar or non-scalar. Several categories for user-defined types that can be used as data Oracle Database provides many built-in data types as well as Values that each column can hold, or each argument can Procedure or stored function, you need to state a data type forĮach of its arguments. State a data type for each of its columns. When you create a table or a cluster, you must have to You can add values of NUMBER data type, but not values of a RAWĭata type. These properties treat values of one data typeĭifferently from values of another. The data type of value links a fixed set of properties with So basically, you have to beįamiliarizing yourself with the basic concepts covered in thisĮvery value controlled by Oracle Database has a specific data These elements are the simplestīuilding blocks of SQL statements.
In this chapter, you will get reference information on theįundamental elements of Oracle SQL.
