一、获取表的基本信息 

 SELECT [TableName] = [Tables].name ,

        [TableOwner] = [Schemas].name ,

        [TableCreateDate] = [Tables].create_date ,

        [TableModifyDate] = [Tables].modify_date

FROM    sys.tables AS [Tables]

        INNER JOIN sys.schemas AS [Schemas] ON [Tables].schema_id = [Schemas].schema_id

WHERE   [Tables].name = '案卷目录' 

效果如图一所示：

二、根据表名获取字段列表 

SELECT [ColumnName] = [Columns].name ,

        [SystemTypeName] = [Types].name ,

        [Precision] = [Columns].precision ,

        [Scale] = [Columns].scale ,

        [MaxLength] = [Columns].max_length ,

        [IsNullable] = [Columns].is_nullable ,

        [IsRowGUIDCol] = [Columns].is_rowguidcol ,

        [IsIdentity] = [Columns].is_identity ,

        [IsComputed] = [Columns].is_computed ,

        [IsXmlDocument] = [Columns].is_xml_document ,

        [Description] = [Properties].value

FROM    sys.tables AS [Tables]

        INNER JOIN sys.columns AS [Columns] ON [Tables].object_id = [Columns].object_id

        INNER JOIN sys.types AS [Types] ON [Columns].system_type_id = [Types].system_type_id

                                           AND is_user_defined = 0

                                           AND [Types].name <> 'sysname'

        LEFT OUTER JOIN sys.extended_properties AS [Properties] ON [Properties].major_id = [Tables].object_id

                                                              AND [Properties].minor_id = [Columns].column_id

                                                              AND [Properties].name = 'MS_Description'

WHERE   [Tables].name =案卷目录

ORDER BY [Columns].column_id

 

 效果如图二所示：

三、获取指定存储过程参数列表 

SELECT sc.name AS 参数名 ,

        st.name AS 类型 ,

        sc.length AS 长度

FROM    syscolumns sc

        INNER JOIN sysobjects so ON so.id = sc.id

        INNER JOIN systypes st ON sc.xtype = st.xtype

WHERE   so.name = 'SP_Pagination'

 

效果如图三所示：
