1. check table for sample
SELECT *,@@hostname,@@version FROM teguhth.pembelian
2. Create table for cdc
# create table
CREATE TABLE audit_table (
id INT AUTO_INCREMENT PRIMARY KEY,
table_name VARCHAR(100),
action_type ENUM('INSERT', 'UPDATE', 'DELETE'),
old_data JSON,
new_data JSON,
changed_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
performed_by VARCHAR(100)
);
ALTER TABLE audit_table
ADD COLUMN performed_by VARCHAR(100);
SELECT *,@@hostname,@@version FROM audit_table;
3. create trigger Change Data Capture for insert, update & delete
# cdc insert
DELIMITER //
CREATE TRIGGER cdc_trigger_insert
AFTER INSERT ON teguhth.pembelian
FOR EACH ROW
BEGIN
INSERT INTO audit_table (table_name, action_type, new_data, performed_by)

SELECT *,@@hostname,@@version FROM audit_table;
