How To Update a Table Row with a Record?
Answer:
If you have a RECORD variable with data fields matching a table structure, you can update a row in this table with this RECORD variable using the UPDATE ... SET ROW statement as shown in the sample script below:
CREATE TABLE emp_temp AS SELECT * FROM employees;
CREATE OR REPLACE PROCEDURE ggl_CENTER AS
manager employees%ROWTYPE;
BEGIN
SELECT * INTO manager FROM employees
WHERE employee_id = 100;
manager.employee_id := 299;
INSERT INTO emp_temp VALUES manager;
manager.first_name := 'ggl';
manager.last_name := 'Center';
UPDATE emp_temp SET ROW = manager WHERE employee_id = 299;
DBMS_OUTPUT.PUT_LINE('# rows updated = ' || SQL%ROWCOUNT);
END;
/
# rows updated = 1
CREATE TABLE emp_temp AS SELECT * FROM employees;
CREATE OR REPLACE PROCEDURE ggl_CENTER AS
manager employees%ROWTYPE;
BEGIN
SELECT * INTO manager FROM employees
WHERE employee_id = 100;
manager.employee_id := 299;
INSERT INTO emp_temp VALUES manager;
manager.first_name := 'ggl';
manager.last_name := 'Center';
UPDATE emp_temp SET ROW = manager WHERE employee_id = 299;
DBMS_OUTPUT.PUT_LINE('# rows updated = ' || SQL%ROWCOUNT);
END;
/
# rows updated = 1
