units flag kind Money
名称1 标志1 A 10
名称1 标志2 B 23
名称2 标志3 A 4
名称2 标志2 A 6
名称1 标志1 A 77
名称3 标志3 B 6
其中flag中有3种标志,kind有2个类别,现在要求对其查询结果如下:
名称 标志1 标志2 标志3
名称 Asum(money) Bsum(money) Asum(money) Bsum(money) Asum(money)Bsum(money)
查询结果变成7列,第一列为名称,第二列为类别为A的Money求和,第三列为B的求和,这2个都属于标志1的
4,5列也是分别对A,B的Money求和,属于标志2。标志3类似。
请问如何写查询语句,请高手指点,谢谢!
