如何合并两个数字字段？

Question

如何将两个int列合并为一个。

My table1 is as follows:
name   adress1  adress2
hhh    1        2
www    2        3

我想要的结果如下：

name columnz
hhh  12
www  23

Answer 1

在即将发布的SQL服务器中，您可以执行以下操作：

\n

选择名称concat（address1，address2）作为columnz FROM table1

但是，SQL-server尚不允许concat，因此您将使用'+'运算符和强制类型转换。

SELECT 
  name
  ,CAST(address1 AS char)+CAST(address2 AS char) as columnz
FROM table1

SQL对字符串和数字之间的区别并不那么麻烦。

另一个选择是：

SELECT name, (address1*10+address2) as columnz 
FROM table1

Answer 2

尝试这个：

SELECT name, Concat(adress1, adress2) AS columnz FROM table1;

Answer 3

SELECT name, CAST(ADRESS1 AS VARCHAR(20)) + CAST(ADRESS2 AS VARCHAR(20)) AS columnz from table1

Answer 4

select name, convert(varchar, adress1) + convert(varchar, adress2) as columnz from table1;
