Oracle PL/SQL Data Types

PL/SQL offers a rich set of built-in datatypes that allow you to store data values of different types. In addition to the basic datatypes, PL/SQL provides support for Oracle-specific types such as BFILEs, REFs, and user-defined types. You can also create your own user-defined types.The following table lists the PL/SQL datatypes and gives a brief description of each:DatatypeDescriptionBOOLEANLogical true or false valueCHARFixed-length character stringCONSTANTValue that cannot be changedDATEDate and time value (year, month, day)DECIMALFloating-point number with exact precision (also called BINARY_FLOAT)EXCEPTIONError condition raised explicitly by programFIXED BINARY_INTEGERNUMBER(n)Number stored as an nPL/SQL has a variety of data types, including the following:-Numbers: INTEGER, NUMBER, BINARY_FLOAT, and BINARY_DOUBLE-Strings: CHAR, VARCHAR2, CLOB,and NCLOBBooleans: BOOLEANDates: DATE and TIMESTAMP-LOBs: BLOB and CLOB-Others: RAW, LONG RAW, ROWID, UROWID, and XMLTypePL/SQL has a variety of data types, which can be broadly classified into the following categories. Character Data Types2. Numeric Data Types3. Date and Time Data Types4. Large Object (LOB) Data Types5. User-Defined Data Types6. Reference Data TypesPL/SQL has a rich set of built-in datatypes that allow you to store a wide variety of data in your database tables. This section describes the most common PL/SQL datatypes, including their properties and how they map to Oracle Database column types.The following table shows the PL/SQL datatypes and their properties.DatatypeDescriptionNumberA number is a numeric value with no fractional component. It can be positive, negative, or zero. A number can have up to 38 digits of precision.StringA string is a sequence of characters with a maximum length of 32767 bytes.DateA date is a three-part value representing a year, month, and day in the range of January 1, 4712 BC to December 31, 9999 AD.TimestampA timestamp is a six-part value representing a year, month, day, hour, minute, and second in the
