Question

有人可以帮我查询列出单个服务器中所有数据库中的所有表吗？

提前致谢。

Answer 1

使用sp_MSforeachdb遍历所有数据库，INFORMATION_SCHEMA.TABLES查询每个数据库中的表：

sp_MSforeachdb 'USE [?]; SELECT * FROM INFORMATION_SCHEMA.TABLES'

尝试动态查询

您需要针对sys.tables针对每个数据库进行查询。

select 'master' as DatabaseName, 
       T.name collate database_default as TableName 
from master.sys.tables as T 
union all 
select 'tempdb' as DatabaseName, 
       T.name collate database_default as TableName 
from tempdb.sys.tables as T 
union all 
select 'model' as DatabaseName, 
       T.name collate database_default as TableName 
from model.sys.tables as T 
union all 
select 'msdb' as DatabaseName, 
       T.name collate database_default as TableName 
from msdb.sys.tables as T

您可以使用sys.databases动态构建和执行查询。

declare @SQL nvarchar(max)

set @SQL = (select 'union all 
select '''+D.name+''' as DatabaseName,
       T.name collate database_default as TableName
from '+quotename(D.name)+'.sys.tables as T
'
from sys.databases as D
for xml path(''), type).value('substring((./text())[1], 13)', 'nvarchar(max)')

--print @SQL
exec (@SQL)

IF OBJECT_ID('tempdb.dbo.#tbl') IS NOT NULL
    DROP TABLE #tbl

CREATE TABLE #tbl (
      database_id SYSNAME
    , tbl_name SYSNAME
    , sch_name SYSNAME
    , [rows] INT
)

DECLARE @SQL NVARCHAR(MAX)

SELECT @SQL = STUFF((
    SELECT '
    USE [' + d.name + ']
    INSERT INTO #tbl
    SELECT DB_NAME(), o.name, s.name, p.[rows]
    FROM sys.objects o
    JOIN sys.schemas s ON o.[schema_id] = s.[schema_id]
    LEFT JOIN (
        SELECT p.[object_id], [rows] = SUM(p.[rows])
        FROM sys.partitions p
        WHERE p.index_id < 2
        GROUP BY p.[object_id]
    ) p ON p.[object_id] = o.[object_id]
    WHERE o.[type] = ''U''
        AND o.is_ms_shipped = 0;'
    FROM sys.databases d
    WHERE d.[state] = 0
    FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 2, '')

EXEC sys.sp_executesql @SQL

SELECT * FROM #tbl
