选择stu_name +'---------->' +来自SQL Server中学生的Reg_id [英] select stu_name + '---------->' + Reg_id from student in sql server

问题描述

我想在SQL Server中选择学生ID和他的名字.
就像Anmol Sahrma一样----------> R200911100001.

我试图那样做

从学生中选择stu_name +''---------->''+ Reg_id.

错误是
消息245，第16级，状态1，第1行
将varchar值"Anmol Sahrma ----->"转换为数据类型int时，转换失败.

Error is
Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value ''Anmol Sahrma ----->'' to data type int.

Can any one help me?

推荐答案

尝试

select stu_name + ''---------->'' + CONVERT(varchar, Reg_id) from student

.
Reg_id需要先被转换为字符串，然后才能被连接.

.
Reg_id needs to be converted to string before it is concatenated.

而不是将Varchar转换为int，而是尝试将Int转换为Varchar.

Instead of Convert Varchar to int try Int to Varchar.
