SQL中没有显示列名

Question

在SQL Server 2008中，但不显示列名。我需要输入一个空字符串，因为在报告中手动填充行。

(SELECT '' As 'Total No of people')

它似乎显示为(No column name)

Answer 1

你可以拥有

SELECT ID as 'ID',
(SELECT <....> FROM table WHERE <...> ) AS 'Total No of people'
FROM somewhere

您必须将列名称放在内部选择的)之后

Answer 2

我会说它运作正常！ http://sqlfiddle.com/#!3/d41d8/18149

但也许你的问题是你（技术上使用子查询）

SELECT ID, (SELECT '' As 'Total No of people') FROM SomeWhere

那是错误的......

SELECT ID, '' As 'Total No of people' FROM SomeWhere

或

SELECT ID, (SELECT '') As 'Total No of people' FROM SomeWhere

但内部SELECT

没有理由

Answer 3

确保按顺序排列：SELECT＆＃39;＆＃39;作为＆＃39; Total No of people＆＃39;来自人民
