%ROWTYPE Attribute

The %ROWTYPE attribute provides a record type that represents a row in a database table. The record can store an entire row of data selected from the table or fetched from a cursor or cursor variable. Variables declared using %ROWTYPE are treated like those declared using a datatype name. You can use the %ROWTYPE attribute in variable declarations as a datatype specifier.

Fields in a record and corresponding columns in a row have the same names and datatypes. However, fields in a %ROWTYPE record do not inherit constraints, such as the NOT NULL column or check constraint, or default values. For more information, see "Using the %ROWTYPE Attribute".

Keyword and Parameter Description


An explicit cursor previously declared within the current scope.


A PL/SQL strongly typed cursor variable, previously declared within the current scope.


A database table or view that must be accessible when the declaration is elaborated.

Usage Notes

Declaring variables as the type table_name%ROWTYPE is a convenient way to transfer data between database tables and PL/SQL. You create a single variable rather than a separate variable for each column. You do not need to know the name of every column. You refer to the columns using their real names instead of made-up variable names. If columns are later added to or dropped from the table, your code can keep working without changes.

To reference a field in the record, use dot notation (record_name.field_name). You can read or write one field at a time this way.

There are two ways to assign values to all fields in a record at once:
