PostgreSQL中ON CONFLICT的使用及一些扩展用法

INSERT INTO samples (sample_id_lims, data_field1, data_field2)
VALUES ('123', 'New Data 1', 'New Data 2')
ON CONFLICT (sample_id_lims) DO UPDATE
SET data_field1 = EXCLUDED.data_field1,

INSERT INTO table_name (column1, column2) VALUES (value1, value2)
ON CONFLICT ON CONSTRAINT constraint_name
DO NOTHING; -- 或者 DO UPDATE ...
