SQL中的所有表和所有列？

我希望列出数据库中的每个表以及相应的列标题。SQL有没有办法做到这一点，并在这个过程中按字母顺序排列列名

以下格式行中的某些内容：

Table1    Col1name    Col2name    Col3name ...
Table2    Col1name    Col2name    Col3name ...
...

---

谢谢

SQL Server有一个名为的未记录存储过程，您可以使用它迭代数据库中的所有表

知道表名后，可以使用或查看表中的所有列

SELECT 
  [schema] = s.name,
  [table]  = t.name, 
  [column] = c.name
FROM 
  sys.tables AS t
INNER JOIN
  sys.schemas AS s
  ON t.[schema_id] = s.[schema_id]
INNER JOIN 
  sys.columns AS c
  ON t.[object_id] = c.[object_id]
ORDER BY 
  t.name, 
  c.name;

这就是为什么我不会在SQL Server 2005+中对任何内容使用

信息\u模式的原因：



这会让你朝着正确的方向前进。真正取决于您希望输出的方式：

SELECT t.table_name, STUFF((SELECT distinct ',' + c.COLUMN_NAME 
                  FROM DATABASENAME.INFORMATION_SCHEMA.COLUMNS c WHERE c.TABLE_NAME =t.table_name
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'') as Columns
FROM  DATABASENAME.INFORMATION_SCHEMA.TABLES t 
ORDER BY t.TABLE_NAME, Columns

如果像@Aaron指出的那样使用sys.tables和sys.columns，那么这也应该起作用：

SELECT t.name, STUFF((SELECT distinct ', ' + c.name
                  FROM sys.COLUMNS c WHERE t.object_id = c.object_id
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'') as Columns
FROM sys.TABLES t 
ORDER BY t.name, Columns

祝你好运。
试试这个

    declare @xml as xml
    declare @max_cols int
    declare @i int
    declare @query as varchar(max)
    declare @query_OA2 as varchar(max)

    select @max_cols = MAX(n)
    from(   select COUNT(name) as n
            from sys.columns
            group by object_id
    )V


    select @i = 1, @query_OA2 = ''
    while @i <= @max_cols
    begin
        set @query_OA2 = @query_OA2 +', C.elements.value(''./name['+CAST(@i as varchar(max))+']'',''varchar(max)'') as [Column '+CAST(@i as varchar(max))+']'
        set @i = @i+1
    end
    select @query_OA2 = STUFF(@query_OA2,1,1,'')

    select @query = 'select t.name as [table]
                    ,OA2.*
                    from sys.tables t
                    outer apply (select (select (select c.name from sys.columns c
                                         where c.object_id = t.object_id
                                         order by c.column_id
                                         for xml path(''''),type) for xml path(''columns''),type) as cols
                    )OA
                    outer apply (select '+@query_OA2+'
                                 from OA.cols.nodes(''columns'')C(elements)
                    )OA2
                    order by t.name'
    exec (@query)

做旋转动作

    declare @max_cols int
    declare @i int
    declare @query as varchar(max)
    declare @query2 as varchar(max)

    select @max_cols = MAX(n)
    from(   select COUNT(COLUMN_NAME) as n
        from INFORMATION_SCHEMA.COLUMNS
        group by table_name
    )V


    select @i = 1, @query2 = ''
    while @i <= @max_cols
    begin
        set @query2 = @query2 +', Col_'+CAST(@i as varchar(max))
        set @i = @i+1
    end
    select @query2 = STUFF(@query2,1,1,'')

    select @query =
    'select * 
    from (
            select T.TABLE_NAME,T.COLUMN_NAME,''Col_''+cast(T.ORDINAL_POSITION as varchar(max)) as pos
            from INFORMATION_SCHEMA.COLUMNS T
    )V
    PIVOT (max(V.COLUMN_NAME) for pos in ('+@query2+'))U'

    exec(@query)

我肯定有很多类似这样的问题。您需要将每个列名放在单独的列中，而不是行中？为什么？每个表可能有不同数量的列，这使得按照需要生成有点困难。我建议在您的演示层进行转换。该过程没有文档记录，并且由于某种原因不受支持。：-）无论如何，在这种情况下，它没有多大用处，因为您将只是针对sys.columns或任何地方构建一个查询循环-当您可以使用更简单的连接来满足此查询，并且没有巫毒。仅供参考，我们的两个答案实际上都没有为每一列将列名放入一列中。还有一个很快就被弄糊涂的人。你还说了
SCHEMA
，我想你的意思是
INFORMATION\u SCHEMA
。谢谢@AaronBertrand--我更新了使用信息\u SCHEMA:-）输入了我的实际值
