我想测试如果我用不同的数据类型替换变量会发生什么:
clear
input id x0
1 1
2 13
3 .
end
list
save tabA, replace
clear
input id str5 x0
1 "1"
2 "23"
3 "33"
end
list
save tabB, replace
use tabA, clear
mmerge id using tabB, type(1:1) update replace
list
结果是:
+--------------------------------------------------+
| id x0 _merge |
|--------------------------------------------------|
1. | 1 1 in both, master agrees with using data |
2. | 2 13 in both, master agrees with using data |
3. | 3 . in both, master agrees with using data |
+--------------------------------------------------+
这对我来说似乎很奇怪。我预计崩溃或分歧。这是一个错误还是我错过了什么?
