SQL SELECT语句中的带状字段

Question

我有一个查询，提供4列

EXPR1，EXPR2，MOVE5和数量

qty是所有（6360）的相同值

我希望能够调整查询，以便为每行生成一个新的计算字段，即qty + EXPR2，但每行使用的数量将是前一次计算的结果，但是从初始数量开始

e.g. 
row 1 (1,400,6360,6360)
row2 (-10,401,6360,6350)
row3 (-1,402,6360,6349)  etc


SELECT
    movement_reference AS EXPR1,
    movement_quantity AS EXPR2,
    CAST (CAST(movement_date AS INT) AS VARCHAR(5)) + RIGHT('00000' + CAST(CAST(sequence_no AS INT) AS VARCHAR(6)), 6) AS MOVE5,
    (SELECT physical_qty FROM  stocktable WHERE (product = 'B') AND (warehouse = 'FH')) AS qty
FROM
    stockhistory
WHERE
    (warehouse = 'FH') 
AND
    (product = 'B')
ORDER BY
    dated DESC
