我想查询一个表的所有列的名称。我发现如何做到这一点:
甲骨文 MySQL PostgreSQL
但我也需要知道:如何在Microsoft SQL Server(在我的情况下是2008年)中做到这一点?

--This is another variation used to document a large database for conversion (Edited to --remove static columns)
SELECT o.Name as Table_Name
, c.Name as Field_Name
, t.Name as Data_Type
, t.length as Length_Size
, t.prec as Precision_
FROM syscolumns c
INNER JOIN sysobjects o ON o.id = c.id
LEFT JOIN systypes t on t.xtype = c.xtype
WHERE o.type = 'U'
ORDER BY o.Name, c.Name
--In the left join, c.type is replaced by c.xtype to get varchar types
其他回答
通过使用这个查询,您可以得到答案:
select Column_name
from Information_schema.columns
where Table_name like 'table name'
SELECT column_name, data_type, character_maximum_length, table_name,ordinal_position, is_nullable
FROM information_schema.COLUMNS WHERE table_name LIKE 'YOUR_TABLE_NAME'
ORDER BY ordinal_position
你可以试试这个。这将给出所有列名及其各自的数据类型。
desc <TABLE NAME> ;
SELECT c.Name
FROM sys.columns c
JOIN sys.objects o ON o.object_id = c.object_id
WHERE o.object_id = OBJECT_ID('TABLE_NAME')
ORDER BY c.Name
只需运行这个命令
EXEC sp_columns 'Your Table Name'
