做数据纵向合并的时候,发现有同一字段数据格式不同无法合并,该用什么代码修改格式呢?
报错提示如下:
variable birth_date is byte in master but str10 in using data
You could specify append's force option to ignore this numeric/string mismatch. The using variable would then
be treated as if it contained numeric missing value
ps:使用了destring但因为数据中有“-”而无法转化
