SELECT C.COLUMN_NAME, C.IS_NULLABLE, C.DATA_TYPE, TC.CONSTRAINT_TYPE, C.COLUMN_DEFAULT
    FROM INFORMATION_SCHEMA.COLUMNS AS C
    FULL JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE AS CC ON C.COLUMN_NAME = CC.COLUMN_NAME 
    FULL JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS TC ON CC.CONSTRAINT_NAME = TC.CONSTRAINT_NAME
WHERE C.TABLE_NAME = '<Table Name>';

样例输出

首先连接到你的数据库，

使用DB_name

然后

exec sp_help '生产。Et_Issue”

这里的'production'是模式名。如果你没有图式， 您可以简单地写入sp_help table_name

SELECT C.COLUMN_NAME, C.IS_NULLABLE, C.DATA_TYPE, TC.CONSTRAINT_TYPE, C.COLUMN_DEFAULT
    FROM INFORMATION_SCHEMA.COLUMNS AS C
    FULL JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE AS CC ON C.COLUMN_NAME = CC.COLUMN_NAME 
    FULL JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS TC ON CC.CONSTRAINT_NAME = TC.CONSTRAINT_NAME
WHERE C.TABLE_NAME = '<Table Name>';

样例输出

这些答案的问题在于，你忽略了关键信息。 虽然这是有点混乱，这是一个快速的版本，我提出，以确保它包含相同的信息MySQL描述显示。

Select SC.name AS 'Field', ISC.DATA_TYPE AS 'Type', ISC.CHARACTER_MAXIMUM_LENGTH AS 'Length', SC.IS_NULLABLE AS 'Null', I.is_primary_key AS 'Key', SC.is_identity AS 'Identity'
From sys.columns AS SC 
LEFT JOIN sys.index_columns AS IC
ON IC.object_id = OBJECT_ID('dbo.Expenses') AND 
IC.column_id = SC.column_id
LEFT JOIN sys.indexes AS I 
ON I.object_id = OBJECT_ID('dbo.Expenses') AND 
IC.index_id = I.index_id
LEFT JOIN information_schema.columns ISC
ON ISC.TABLE_NAME = 'Expenses'
AND ISC.COLUMN_NAME = SC.name
WHERE SC.object_id = OBJECT_ID('dbo.Expenses')

以防您不想使用stored proc，这里有一个简单的查询版本

select * 
  from information_schema.columns 
 where table_name = 'aspnet_Membership'
 order by ordinal_position

试一试:

EXEC [ServerName].[DatabaseName].dbo.sp_columns 'TableName'

你可以得到一些表结构的信息，比如:

Table_qualifier, table_owner, table_name, column_name, data_type, type_name…
