Oracle PL/SQL Records Type - Shikshaglobe

A "record" is a data structure that allows you to store information in a single variable. Records are similar to arrays in that they allow you to store multiple values in a single variable, but they are different in that each value in a record has a specific name and data type.You can define a record type using the "type" keyword, and you can create variables of that type using the "var" keyword. For example:type MyRecordType is recordFirstName varchar2(20);LastName varchar2(20);var MyRecord MyRecordType;PL/SQL Records are a data structure that allows you to store data in a structured format. Records are similar to arrays in other programming languages, but they are more flexible and easier to use. You can use records to store data in a single variable, or you can use them to store data in an array of variables. Records are especially useful for storing data from database queries, because they allow you to access individual fields by name.Records are data structures that can hold heterogeneous data items. A record is a collection of fields, each of which has a name and a value. The value can be either a scalar value or another nested record. You can think of a record as an row in a database table, where each field in the record corresponds to a column in the table.Records are useful for storing data that does not fit well into the standard scalar data types (such as numbers, strings, and Booleans). For example, you might want to store information about an employee in a single record. The employee record could include fields for the employee's name, address, job title, salary, and so on.A record is a user-defined data structure that consists of one or more fields, where each field can store a value of any data type. You can think of a record as a row in a database table, where each column in the table represents a field in the record. For example, you could define a record type that represents an employee, with fields for the employee's name, job title, and salary.Records are useful for storing data that is logically related but physically disparate. For example, you might use a record to store information about a customer and her orders. In this case, the customer's name and address would be logically related to her orders (they describe the customer), but they would be physically disparate (stored in different fields in the record).Oracle provides two ways to define records:· Anonymous blocks· Subtypes
