select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='tableName'

这比从sys。列，因为它直接显示DATA_TYPE。

只需运行这个命令

EXEC sp_columns 'Your 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

另一个更直观的选择是:

SELECT [name] 
FROM sys.columns 
WHERE object_id = OBJECT_ID('[yourSchemaType].[yourTableName]') 

这将在一个列中提供所有列名。 如果您关心其他元数据，可以将SELECT语句编辑为SELECT *。

--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

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> ;
