3 PL/SQL Data Types. Every constant, variable, and parameter has a data type (also called a type) that determines its storage format, constraints, valid range of values, and operations that can be performed on it. PL/SQL provides many predefined data types and subtypes, and lets you define your own PL/SQL subtypes.
Oracle Datatypes. 1. Data types for Oracle 7- Oracle 11g + PL/SQL. Datatype. Description. Max. Size: Oracle 7. Max. Size: Oracle 8. Max Size: Oracle. 9i/10g/11g. Max Size: PL/SQL. PL/SQL. Subtypes/. Synonyms. VARCHAR2(size). Variable length character string having maximum length size bytes. You must specify size.
PL/SQL - DATA TYPES. PL/SQL variables, constants and parameters must have a valid data type, which specifies a storage format, constraints, and valid range of values. This tutorial will take you through SCALAR and LOB data types available in PL/SQL and other two data types will be covered in other chapters. Category.
I'd like to create an in-memory array variable that can be used in my PL/SQL code. Discuss each question Meta data describes the database structure, sizes of data types, constraints, applications, authorisation etc., that are used as an integral tool for information resource management.

Tell Me/Show Me. Guidelines for Declaring and Initializing PL/SQL Variables. • Use meaningful names and follow naming conventions. • Declare one identifier per line for better readability, code maintenance, and easier commenting. • Use the NOT NULL constraint when the variable must hold a value. • Avoid using column
PL/SQL provides many predefined datatypes. For instance, you can choose from integer, floating point, character, BOOLEAN , date, collection, reference, and large object (LOB) types.

Composite Data Types. You have learned that variables of scalar data type can hold only one value, whereas a variable of composite data type can hold multiple values of scalar data type or composite data type. There are two types of composite data types: • PL/SQL records: Records are used to treat related but dissimilar
PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. Every PL/SQL constant, variable, parameter, and function return value has a data type that determines its storage format and its valid values and operations. An easy
