It also takes a look at record types, which enable you to work with records that are not necessarily related to a relational table.
PL/SQL makes it very easy to declare records that have the same structure as a table, a view, or the result set of a cursor by offering the %ROWTYPE attribute.
PL/SQL offers special syntax in both the INSERT and UPDATE statements so that you can easily use records to perform those data manipulation language (DML) operations as well.
The most common form of an INSERT statement is where column_list is the list of columns that will be populated on insert and expression_list is the list of expressions that will be assigned to their respective columns.
I can also use %ROWTYPE to declare a record that has the same structure as a SELECT statement in a cursor.Tables are made up of rows of data, each consisting of one or more columns, so it stands to reason that Oracle Database would make it as easy as possible to work with those rows of data inside a PL/SQL program.And it does precisely that through its implementation of the datatype, such as a number or string.The following block uses a cursor FOR loop to fetch only the last name of each employee, deposit that name into a record, and then display the value of the last_name field of that record: You can define parameters based on record types, and you can therefore pass records as arguments to subprograms.Suppose I need to write a procedure that displays an employee.
