MYSQL 对表的一列数字进行分组循环累加(当前行的值累加上一行的值)

有这样的原始表: 
X1 X2 
———————– 
2 453 
2 120 
2 101 
2 89 
3 111 
3 421 
3 219 
———————– 

根据 X1 字段进行累加,我要循环累加后变成下面的表 
X1 X2 
———————– 
2 453 
2 573 
2 674 
2 763 
3 111 
3 532 
3 751 
———————– 

CREATE TABLE test
(
    Id INT NOT NULL AUTO_INCREMENT,
    X1 INT NOT NULL,
    X2 INT NOT NULL,
PRIMARY KEY(`Id`)
)
 
INSERT  INTO test(X1,X2) VALUES(2,453),(2,120),(2,101),(2,89),(3,111),(3,421),(3,219)
 
SELECT * FROM test
 
 
SELECT X1,(SELECT SUM(X2) FROM test WHERE X1=A.X1 AND Id<=A.Id)
FROM test A
 
-----------------------
 
X1    (SELECT SUM(X2) from test where X1=A.X1 and Id<=A.Id)
2    453
2    573
2    674
2    763
3    111
3    532
3    751
