CREATE TABLE test( paytype VARCHAR(10),goods VARCHAR(10),money INT) ENGINE=INNODB; 

INSERT INTO test VALUES('微信','商品1',80);  
INSERT INTO test VALUES('支付宝','商品2',120);  
INSERT INTO test VALUES('支付宝','商品1',80);  
INSERT INTO test VALUES('微信','商品1',60);

    SUM(IF(paytype="微信",money,0)) AS "微信",  
    SUM(IF(paytype="支付宝",money,0)) AS "支付宝"
    
FROM test   
GROUP BY goods
