下面的查询动态生成一个SQL语句，该语句由您需要的UNIONED语句组成。然后，您只需在该生成的语句上运行exec sp_executesql，并将结果插入到临时表中。
create table #temp (
ID int identity,
Name varchar(100),
Value decimal(18,6))
declare @sql nvarchar(max)
select
@sql = coalesce(
@sql + '
UNION ALL SELECT ''SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + '))'',
SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + ')) FROM myTable',
'SELECT ''SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + '))'',
SQRT(SUM(' + a.COLUMN_NAME + '*' + b.COLUMN_NAME + ')) FROM myTable')
from
information_schema.COLUMNS a
cross join information_schema.COLUMNS b
where
a.TABLE_NAME = 'myTable'
and b.TABLE_NAME = 'myTable'
and CONVERT(int, substring(a.COLUMN_NAME, 2, len(a.COLUMN_NAME) - 1)) <=
CONVERT(int, substring(b.COLUMN_NAME, 2, len(b.COLUMN_NAME) - 1))
order by
CONVERT(int, substring(a.COLUMN_NAME, 2, len(a.COLUMN_NAME) - 1)),
CONVERT(int, substring(b.COLUMN_NAME, 2, len(b.COLUMN_NAME) - 1))
--print @sql
insert into #temp(Name,Value)
EXEC sp_executesql @sql
--drop table #temp

你可以做Derek建议的，或者（我认为这是一种更好的方法）你可以改变你的数据库设计有2个表：
CREATE TABLE [Keys] (
[Id] int IDENTITY(1,1) NOT NULL,
[Name] varchar(10) NOT NULL,
PRIMARY KEY CLUSTERED (Id)
)
CREATE TABLE [Values] (
[Id] int IDENTITY(1,1) NOT NULL,
[KeyId] int NOT NULL,
[Value] float NOT NULL,
PRIMARY KEY CLUSTERED (Id)
)
在这种情况下，您的查询将类似于
SELECT
V.KeyId AS Id,
'SQRT(SUM(' + K.Name + '*' + K.Name + '))' AS Name,
SQRT(SUM(V.Value * V.Value)) AS Value
FROM Values V INNER JOIN Keys K ON V.KeyId = K.Id
GROUP BY KeyId
编辑：试试这个。
--DROP TABLE [Values]
--DROP TABLE [Keys]
CREATE TABLE [Keys] (
[Id] int IDENTITY(1,1) NOT NULL,
[Name] varchar(100) NOT NULL,
PRIMARY KEY CLUSTERED (Id)
)
CREATE TABLE [Values] (
[Id] int IDENTITY(1,1) NOT NULL,
[KeyId] int NOT NULL,
[Value] float NOT NULL,
PRIMARY KEY CLUSTERED (Id)
)
INSERT INTO Keys (Name)
SELECT SUBSTRING(COLUMN_NAME, 0, 100)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'MyTable'; -- Change this to your current table's name
SELECT * FROM MyTable -- Change this to your current table's name
DECLARE @i int
DECLARE @iMax int
SET @i = 1;
SELECT @iMax = COUNT(*) FROM Keys
WHILE (@i <= @iMax)
BEGIN
DECLARE @column varchar(100)
SELECT @column = Name FROM Keys WHERE Id = @i;
DECLARE @sql nvarchar(max)
SET @sql = 'INSERT INTO [Values] (KeyId, Value)
SELECT ' + CONVERT(nvarchar, @i) + ', A.' + @column + '
FROM MyTable A'; -- Change this to your current table's name
EXEC sp_executesql @sql;
SET @i = @i + 1
END
SELECT * FROM [Keys]
SELECT * FROM [Values]
