1. Define a TABLE data type
TYPE type_name IS TABLE OF
(column_type | variable%TYPE
| table.column%TYPE | table%ROWTYPE
INDEX BY BINARY_INTEGER);
2 Declare a variable of that type
identifier type_name;
Assume the PLsql table (emp_table_type) has emp's first
name and index columns and you want to display this column
data (Emp's first name)
TYPE type_name IS TABLE OF
employee.firstname%TYPE
INDEX BY BINARY_INTEGER;
emp_table_type type_name;
Load data into emp_table_type table
-- Display emp's first name data
FOR index in EMP_table_type.FIRST..EMP_table_type.LAST
LOOP
DBMS_OUTPUT.PUT_LINE(EMP_table_type(index));
END LOOP;
