合并一些列

Question

我正在尝试从包含多个列的表（称为地址）返回信息。物理地址分为line1，line2，city，state等。我想显示表中的所有列，但希望将line1和line2列合并为一个名为street的列。

有没有办法在不列出表格中的每一列的情况下执行此操作？

SELECT Line1 + ',' + Line2, city, state From Address

<强>（OR）

SELECT concat(line1, ' , ', line2) , city, state From Address

Answer 2

SELECT line1 + line2 AS street, city, state FROM addresses

Answer 3

试试这个..

SELECT Line1 + ',' + Line2 as Street, city, state From [TableName]
