It focuses on multitable INSERT statements, types of multitable INSERT statements, external tables, and the provision to name the index at the time of creating a primary key constraint. Review of the INSERT Statement Add new rows to a table by using the INSERT statement. Only one row is inserted at a time with this syntax. INSERT INTO table [(column [, column.])] VALUES (value [, value.]); INSERT INTO departments(department_id, department_name, manager_id, location_id) VALUES (70, 'Public Relations', 100, 1700); 1 row created. Review of the INSERT Statement You can add new rows to a table by issuing the INSERT statement. In the syntax: table is the name of the table column is the name of the column in the table to populate value is the corresponding value for the column Note: This statement with the VALUES clause adds only one row at a time to a table. Instructor Note You can skip this slide if the students are already familiar with these concepts. Review of the UPDATE Statement Modify existing rows with the UPDATE statement. Update more than one row at a time, if required. Specific row or rows are modified if you specify the WHERE clause. UPDATE table SET column = value [, column = value, .] [WHERE condition]; UPDATE employees SET department_id = 70 WHERE employee_id = 142; 1 row updated.
