sql server中查看列詳細(xì)信息的語(yǔ)句
sql server數(shù)據(jù)庫(kù)的列信息查看的方法是最常用的操作方法之一，本文為您詳述了怎么使用T-Sql語(yǔ)句， 在sql server 2005中提取一個(gè)數(shù)據(jù)表的列的詳細(xì)信息的方法，并附sql server的開(kāi)發(fā)實(shí)例，供您參考，希望對(duì)您有所幫助。
下面介紹的是名為sp_GetColumnsInfo的存儲(chǔ)過(guò)程，示例中使用了微軟提供的AdventureWorks數(shù)據(jù)庫(kù)。
USE AdventureWorks;
--Method I: Using System Store Procedure
EXEC SP_COLUMNS @table_name = N'Employee'
GO
--Method II: Using T-Sql Statement
--If existed, delete the store procedure
IF EXISTS (
SELECT *
FROM INFORMATION_SCHEMA.ROUTINES
WHERE SPECIFIC_SCHEMA = N'dbo'
AND SPECIFIC_NAME = N'sp_GetColumnsInfo'
)
DROP PROCEDURE [dbo].sp_GetColumnsInfo
GO
--create store procedure, two parameters schema name and table name
CREATE PROCEDURE sp_GetColumnsInfo
@schema NVARCHAR(100),
@tablename NVARCHAR(100)
AS
BEGIN#p#
SELECT
[columns].NAME AS [Name],
[usertype].NAME AS [DataType],
ISNULL([basetype].NAME, N'') AS [SystemType],
CAST(CASE WHEN [basetype].NAME IN (N'nchar', N'nvarchar') AND [columns].max_length <> -1 THEN
[columns].max_length/2 ELSE [columns].max_length END AS INT) AS [Length],
CAST([columns].PRECISION AS INT) AS [NumericPrecision]
FROM
SYS.TABLES AS [table]
INNER JOIN SYS.ALL_COLUMNS AS [columns] ON [columns].OBJECT_ID=[table].OBJECT_ID
LEFT OUTER JOIN SYS.TYPES AS [usertype] ON [usertype].user_type_id = [columns].user_type_id
LEFT OUTER JOIN SYS.TYPES AS [basetype] ON [basetype].user_type_id = [columns].system_type_id and [basetype].user_type_id = [basetype].system_type_id
WHERE
([table].NAME=@tablename and SCHEMA_NAME([table].schema_id)=@schema)
ORDER BY
[columns].column_id ASC
END
EXEC sp_GetColumnsInfo @schema = N'HumanResources', @tablename = N'Employee'
結(jié)果顯示
(16 row(s) affected)
