您可以使用sp_columns存储过程:exec sp_columns MyTable

谢谢-我即将用T-SQL而不是MSSQL发布相同的问题。

即使使用极大的终端宽度,sp_columns的输出在sqlcmd中也无法读取。使用下面找到的select的解决方案更适合sqlcmd用户。

有几种获取有关表的元数据的方法:EXEC sp_help tablename
将返回几个结果集,描述该表,它的列和约束。
INFORMATION_SCHEMA
视图将为您提供所需的信息,尽管很遗憾,您必须查询视图并手动将其加入。评论
对我来说,它没有“ @”字符EXEC sp_help'table_name'

看起来@tablename在示例中是一个变量。 sp通过字符串或'plain'表名(exec sp_help Employees或exec sp_help'Employees')双向工作

以防万一您不想使用存储的proc,这是一个简单的查询版本select *
from information_schema.columns
where table_name = 'aspnet_Membership'
order by ordinal_position

就我而言,如果由于某些原因这些存储的过程不可用,这也适用。

您可以使用以下代码:sp_help tablename
示例:
sp_help Customer
或使用快捷键
Select
所需的表并按ALT + F1。示例:客户按ALT + F1。
评论
请注意,如果该表处于用户定义的架构中,则应将其从查询中排除。包含具有该名称的表的所有模式都将出现在结果集中的“ TABLE_OWNER”列中。
– Buggieboy

请注意,要使用快捷方式,必须完全选择表/视图/过程。 SSMS不会自动扩展选择范围(我原本希望如此)。 Ctrl + W可用于展开选择并选择整个名称。

上面提到的select可以用于一个系统标记的存储过程,可以通过一种简单的方法从您实例的任何数据库中调用它:
USE master;
GO
IF OBJECT_ID('sp_desc', 'P') IS NOT NULL
DROP PROCEDURE sp_desc
GO
CREATE PROCEDURE sp_desc (
@tableName nvarchar(128)
) AS
BEGIN
DECLARE @dbName sysname;
DECLARE @schemaName sysname;
DECLARE @objectName sysname;
DECLARE @objectID int;
DECLARE @tmpTableName varchar(100);
DECLARE @sqlCmd nvarchar(4000);
SELECT @dbName = PARSENAME(@tableName, 3);
IF @dbName IS NULL SELECT @dbName = DB_NAME();
SELECT @schemaName = PARSENAME(@tableName, 2);
IF @schemaName IS NULL SELECT @schemaName = SCHEMA_NAME();
SELECT @objectName = PARSENAME(@tableName, 1);
IF @objectName IS NULL
BEGIN
PRINT 'Object is missing from your function call!';
RETURN;

SELECT @objectID = OBJECT_ID(@dbName + '.' + @schemaName + '.' + @objectName);
IF @objectID IS NULL

RETURN;
END;
SELECT @tmpTableName = '#tmp_DESC_' + CAST(@@SPID AS VARCHAR) + REPLACE(REPLACE(REPLACE(REPLACE(CAST(CONVERT(CHAR, GETDATE(), 121) AS VARCHAR), '-', ''), ' ', ''), ':', ''), '.', '');
--PRINT @tmpTableName;

FROM
::fn_listextendedproperty (''MS_Description'', ''user'', ''' + @schemaName + ''', ''table'', ''' + @objectName + ''', ''column'', default)

SELECT * FROM ' + @tmpTableName + ';'
--PRINT @sqlCmd;
EXEC sp_executesql @sqlCmd;
RETURN;
END;
GO
EXEC sys.sp_MS_marksystemobject sp_desc
GO
要执行该过程,请输入:
EXEC sp_desc 'YourDB.YourSchema.YourTable';
如果要获取描述,请提供当前数据库(和架构)的对象的简单类型:
EXEC sp_desc 'YourTable';
作为sp_desc是一个系统标记的过程,您甚至也可以保留exec命令(无论如何也不建议):
sp_desc 'YourTable';
#10 楼
您可以使用sp_help'TableName'#11 楼
与Oracledescribe
命令等效的SQL Server是存储的proc sp_help
describe
命令为您提供有关列名,类型,长度等的信息。在SQL Server中,假设您要在数据库“ mydb”中的模式“ myschema”中描述表“ mytable”,则可以执行以下操作:
USE mydb;
exec sp_help 'myschema.mytable';
#12 楼
这些答案的问题是您缺少关键信息。虽然有点混乱,但是我想出了一个快速版本,以确保它包含MySQL Describe显示的相同信息。
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'

除了上述问题之外,如果我们在数据库中有类似db_name.dbo.table_name
的表,则可以使用以下步骤与DB连接
USE db_name;
使用
EXEC sp_help
,如果您将'dbo.tablename'
作为架构,请不要忘记将表名放在dbo
。exec sp_help 'dbo.table_name'
这应该可以工作!
#15 楼
使用SELECT COL_LENGTH('tablename', 'colname')

如果您使用的是Brent Ozar团队的FirstResponderKit,则还可以运行此查询:exec sp_blitzindex @tablename='MyTable'
它将返回有关表的所有信息:

和其他

当然,它不是一个系统,也不像sp_help或sp_columns这样通用的stp,但它返回有关表的所有可能信息,我认为值得在此创建它您的环境并在此处提及。
