sql - 字符串或二进制数据在 asp.net 中将被截断

Question

当我尝试执行时，出现字符串或二进制数据将被截断错误

Insert into Student_info (StudentId,FirstName,LastName,DOB,StudentAddress,StudentEmail,StudentMobile) 
                         (Select StudentId,FirstName,LastName,DOB,Address,EmailId,Mobile from Student_temp where StudentId='" & studentid & "')

Student_Temp的表结构

Student_Info的表结构

需要帮助!!

Answer 1

当您尝试将字符串或二进制数据插入到宽度不足以容纳的列中时，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

据猜测，这是因为您的 Student_info.StudentMobile 是 varchar(10) 而 Student_temp.Mobile 是 varchar(50)
