Answer 1

当您尝试将字符串或二进制数据插入到没有足够宽度容纳它的列中时，SQL Server 会报告此错误，例如

create table MyTable
(
    Column1 VARCHAR(10)
)

insert into MyTable (Column1) VALUES ('1234567890A')

Msg 8152, Level 16, State 14, Line 1
String or binary data would be truncated

猜测，这是因为你Student_info.StudentMobile是varchar(10)而Student_temp.Mobile is varchar(50)
