我试图创建下表:
JpId | JpName | JpValue | JpEndvalue
JpEndValue来自同一个表的JpValue(TimeStamp + 1day),但我得到了这个结果:
表:
JpId JpName JpTimeStamp JpValue
1 MAGIC 2017-06-15 151
2 BASIC 2017-06-15 152
3 MINI 2017-06-15 153
4 SUPER 2017-06-15 154
5 MAGIC 2017-06-16 161
6 BASIC 2017-06-16 162
7 MINI 2017-06-16 163
8 SUPER 2017-06-16 164
查询
SELECT jp1.JpId
,jp1.JpName
,jp1.JpValue
,jp2.JpValue AS 'JpEndValue'
FROM jackpot_web_report jp1
LEFT JOIN jackpot_web_report jp2
ON jp2.JpTimeStamp = '2017-06-16'
WHERE jp1.JpTimeStamp = '2017-06-15';
结果:
1 MAGIC 151 161
1 MAGIC 151 162
1 MAGIC 151 163
1 MAGIC 151 164
2 BASIC 152 161
2 BASIC 152 162
2 BASIC 152 163
2 BASIC 152 164
3 MINI 153 161
3 MINI 153 162
3 MINI 153 163
3 MINI 153 164
4 SUPER 154 161
4 SUPER 154 162
4 SUPER 154 163
4 SUPER 154 164
预期结果:
1 MAGIC 151 161
2 BASIC 152 162
3 MINI 153 163
4 SUPER 154 164
答案 0 :(得分:2)
我似乎错过了@BindingAdapter("layout_marginBottom")
public static void setMarginBottom(View view, int margin) {
ViewGroup.LayoutParams params = view.getLayoutParams();
if (params instanceof ViewGroup.MarginLayoutParams) {
ViewGroup.MarginLayoutParams margins = (ViewGroup.MarginLayoutParams) params;
margins.bottomMargin = margin;
view.requestLayout();
}
}
条件:
jp2.JpName = jp1.JpName
您还可以在加入条件中添加SELECT jp1.JpId
,jp1.JpName
,jp1.JpValue
,jp2.JpValue AS 'JpEndValue'
FROM jackpot_web_report jp1
LEFT JOIN jackpot_web_report jp2
ON jp2.JpTimeStamp = '2017-06-16' AND jp2.JpName = jp1.JpName
WHERE jp1.JpTimeStamp = '2017-06-15';
