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> ;

在SQL Server 2008中可以使用sp_help。

sp_help <table_name>;

以上命令的键盘快捷键:选择表名(即突出显示它)并按ALT+F1。

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

--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

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

这比从sys。列，因为它直接显示DATA_TYPE。

你可以尝试使用:-

USE db_name;
DESCRIBE table_name;

它会给你带有类型的列名。
