employeesROWTYPE

employeesROWTYPE is a user-defined record type in SQL, commonly found in Oracle Database environments. It is used to represent a single row of the EMPLOYEES table. This record type is automatically generated by the database when a table is created.

The structure of employeesROWTYPE mirrors the columns of the EMPLOYEES table. For example, if the EMPLOYEES table has columns such as EMPLOYEE_ID, FIRST_NAME, LAST_NAME, and SALARY, then an employeesROWTYPE variable can hold values for all these columns in a structured manner. This allows developers to treat an entire row as a single variable, simplifying the manipulation and passing of row data.

This type is particularly useful within PL/SQL procedures, functions, and triggers. Instead of declaring individual variables for each column of the EMPLOYEES table, a single variable of type employeesROWTYPE can be declared. This variable can then be populated with data fetched from the table, making code more readable and maintainable. For instance, a SELECT INTO statement can directly fetch a row into an employeesROWTYPE variable.

When working with employeesROWTYPE, individual fields can be accessed using dot notation, such as employees_rec.EMPLOYEE_ID or employees_rec.FIRST_NAME, where employees_rec is a variable declared as employeesROWTYPE. This makes it easy to process or modify specific attributes of the row.

In summary, employeesROWTYPE provides a convenient way to manage and access entire rows from the EMPLOYEES table as a single entity within SQL and PL/SQL, improving code efficiency and clarity.
