什么是SQL Server中的'describe table'？

标签： sql sql-server

我有一个SQL Server数据库，我想知道它有哪些列和类型。我更喜欢通过查询而不是使用像企业管理器这样的GUI来实现这一点。有没有办法做到这一点？

答案 0 :(得分：293)

您可以使用sp_columns存储过程：

exec sp_columns MyTable

答案 1 :(得分：95)

有几种方法可以获取有关表的元数据：

EXEC sp_help tablename

将返回几个结果集，描述表，它的列和约束。

INFORMATION_SCHEMA视图会为您提供所需的信息，但不幸的是，您必须查询视图并手动加入。

答案 2 :(得分：45)

如果你不想使用存储过程，这里是一个简单的查询版本

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

答案 3 :(得分：29)

使用此查询

Select * From INFORMATION_SCHEMA.COLUMNS Where TABLE_NAME = 'TABLENAME'

答案 4 :(得分：29)

您可以使用以下

sp_help tablename

实施例： sp_help客户

OR 使用快捷方式

  • 选择表按Alt + F1

示例：客户按Alt + F1

答案 5 :(得分：15)

只需选择表并按 Alt + F1 ，

它将显示有关表的所有信息，如列名，数据类型，键等。

答案 6 :(得分：14)

除了其他答案中显示的方式外，您还可以使用

SELECT TOP 0 * FROM table_name

这将为您提供每列的名称，但不会产生结果，并且几乎可以立即完成，且开销最小。

答案 7 :(得分：13)

请使用以下sql查询;这适用于我的情况。

select * FROM   INFORMATION_SCHEMA.Columns where table_name = 'tablename';

答案 8 :(得分：7)

我在t-sql中编写了一个sql * plus DESC（RIBE），如select（也显示列注释）：

USE YourDB
GO

DECLARE @objectName NVARCHAR(128) = 'YourTable';

SELECT
  a.[NAME]
 ,a.[TYPE]
 ,a.[CHARSET]
 ,a.[COLLATION]
 ,a.[NULLABLE]
 ,a.[DEFAULT]
 ,b.[COMMENTS]
-- ,a.[ORDINAL_POSITION]
FROM
  (
    SELECT
      COLUMN_NAME                                     AS [NAME]
     ,CASE DATA_TYPE
        WHEN 'char'       THEN DATA_TYPE  + '(' + CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR) + ')'
        WHEN 'numeric'    THEN DATA_TYPE  + '(' + CAST(NUMERIC_PRECISION AS VARCHAR) + ', ' + CAST(NUMERIC_SCALE AS VARCHAR) + ')'
        WHEN 'nvarchar'   THEN DATA_TYPE  + '(' + CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR) + ')'
        WHEN 'varbinary'  THEN DATA_TYPE + '(' + CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR) + ')'
        WHEN 'varchar'    THEN DATA_TYPE   + '(' + CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR) + ')'
        ELSE DATA_TYPE
      END                                             AS [TYPE]
     ,CHARACTER_SET_NAME                              AS [CHARSET]
     ,COLLATION_NAME                                  AS [COLLATION]
     ,IS_NULLABLE                                     AS [NULLABLE]
     ,COLUMN_DEFAULT                                  AS [DEFAULT]
     ,ORDINAL_POSITION
    FROM   
      INFORMATION_SCHEMA.COLUMNS
    WHERE
      TABLE_NAME = @objectName
  ) a
  FULL JOIN
  (
   SELECT
     CAST(value AS NVARCHAR)                        AS [COMMENTS]
    ,CAST(objname AS NVARCHAR)                      AS [NAME]
   FROM
     ::fn_listextendedproperty ('MS_Description', 'user', 'dbo', 'table', @objectName, 'column', default)
  ) b
  ON a.NAME COLLATE YourCollation = b.NAME COLLATE YourCollation
ORDER BY
  a.[ORDINAL_POSITION];

上面提到的select可以在系统标记的存储过程中使用，并且可以通过简单的方式从您的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;
    END;

  SELECT @objectID = OBJECT_ID(@dbName + '.' + @schemaName + '.' + @objectName);
  IF @objectID IS NULL
    BEGIN
      PRINT 'Object [' + @dbName + '].[' + @schemaName + '].[' + @objectName + '] does not exist!';
      RETURN;
    END;

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

         ,ORDINAL_POSITION
        FROM   
          INFORMATION_SCHEMA.COLUMNS
        WHERE   
          TABLE_NAME = ''' + @objectName + '''
      ) a
      FULL JOIN
      (
         SELECT
           CAST(value AS NVARCHAR)                        AS [COMMENTS]
          ,CAST(objname AS NVARCHAR)                      AS [NAME]

    SELECT * FROM ' + @tmpTableName + ';'

    --PRINT @sqlCmd;

    EXEC sp_executesql @sqlCmd;
    RETURN;
END;
GO

EXEC sys.sp_MS_marksystemobject sp_desc
GO

执行程序类型：

EXEC sp_desc 'YourDB.YourSchema.YourTable';

如果要获取描述当前数据库（和模式）的对象简单类型：

EXEC sp_desc 'YourTable';

由于sp_desc是一个系统标记过程，你甚至可以保留exec命令（不推荐不推荐）：

sp_desc 'YourTable';

试试看：

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

并且可以得到一些表结构信息，例如：

TABLE_QUALIFIER、TABLE_OWNER、TABLE_NAME、COLUMN_NAME、DATA_TYPE、TYPE_NAME...

答案 11 :(得分：2)

除了上述问题外，如果我们在数据库中有db_name.dbo.table_name之类的表，则可以使用以下步骤

  1. 与数据库连接

    USE db_name;

  2. 使用EXEC sp_help，如果您有'dbo.tablename'作为架构，请不要忘记将表名设置为dbo。

    exec sp_help 'dbo.table_name'

这应该有效！

答案 12 :(得分：2)

您可以使用sp_help＆＃39; TableName＆＃39;

答案 13 :(得分：1)

这些答案的问题在于您错过了关键信息。 虽然这有点乱，但这是我提出的一个快速版本，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'
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')

与Oracle describe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”中的架构“ myschema”中描述表“ mytable”，则可以执行以下操作：

USE mydb;
exec sp_help 'myschema.mytable';

如果您使用的是来自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：

  • 索引及其使用情况统计信息（读，写，锁等），空间 二手和其他
  • 缺少索引
  • 列
  • 外键
  • 统计内容 sp_BlitzIndex sample

当然这不是一个系统，也不是像 sp_help 或 sp_columns 这样的通用stp，但是它会返回有关表的所有可能信息，我认为值得在您的环境并在此处提及。

下面的查询将提供与python Pandas库中的info()函数类似的输出。

USE [Database_Name]

IF OBJECT_ID('tempdo.dob.#primary_key', 'U') IS NOT NULL DROP TABLE #primary_key

SELECT

FROM
INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS CONS_T 
JOIN INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE AS CONS_C ON CONS_C.CONSTRAINT_NAME= CONS_T.CONSTRAINT_NAME


SELECT
