如何检索我正在执行选择的表的列名?我正在尝试将结果附加到每个字段名称的先前结果。
示例(不起作用):
declare @result as nvarchar(max)
concat(select distinct parse(@result, COLName(field1), N':' from sometable, field1))
id,unit
`---------`
1,quart
2,gallon
3,liter
id:1,2,3 单位:夸脱,加仑,升
我实际上是尝试在我的表中包含text,varchar,char的每个字段上使用以下select语句执行此操作,其中size大小小于4000:
我正在尝试解析的表的实际字段列表(这有效):
select top 1000 SCHEMA_NAME([o].schema_id) as [Schema Name],
[s].name as [Table Name],
[c].name as [Field Name],
[t].name as [Type],
[c].max_length as [Length],
[c].precision,
[c].scale,
[c].is_identity
from sys.sysobjects as [s]
inner join sys.all_columns as [c] on [s].id = [c].object_id
inner join sys.systypes as [t] on [c].system_type_id = [t].xtype
inner join sys.objects as [o] on [s].id = [o].object_id
where [s].xtype like 'U' and [t].name not like 'sysname%' and [s].name=N'TableName'
这样我就能清楚地看到每个具有不同结果集的字段的名称。

如果您事先了解文件列表,则可以使用以下内容:
SELECT
(
SELECT cast(id as varchar(50)) + ','
FROM sometable
ORDER by id
FOR XML PATH('')
) as list1
UNION ALL
SELECT
(
SELECT unit + ','
FROM sometable
ORDER by id
FOR XML PATH('')
) as list2
...
