我有以下SQL表:
declare @t table(START_DATE datetime,INDEX_ID int, GROSS_SALES_PRICE decimal(10,2));
insert into @t values
('20150619',10000410,38)
,('20170311',10000410,26.49)
,('20170312',10000410,26.49)
,('20170317',10000410,38)
,('20170318',10000410,38)
,('20170321',10000410,38);
我想检查GROSS_SALES_PRICE
例如,在此表格中,我的价格为38
,然后我有两行26.49
,然后再次38
。可以有任意数量的低价行,所以我认为我必须检查多个前一行?
如果发生这种情况,我想制作值为1
的第三列:
答案 0 :(得分:1)
public class PermissionDialogManager extends DialogFragment { public static PermissionDialogManager newInstance(Bundle bundle) { PermissionDialogManager frag = new PermissionDialogManager(); frag.setArguments(bundle); return frag; } @Override public Dialog onCreateDialog(Bundle savedInstanceState) { ... } }
INDEX_ID | GROSS_SALES_PRICE | CHANGED -------: | :---------------- | ------: 10000410 | 38.00 | 0 10000410 | 26.49 | 1 10000410 | 26.49 | 1 10000410 | 38.00 | 0 10000410 | 38.00 | 0 10000410 | 38.00 | 0
