Question

我在一个服务器数据库中有表结构，我想将数据复制到另一个服务器数据库表。怎么实现呢？

注意:(失败案例）
尝试1：我尝试了备份和恢复，但因版本问题（10.50.2500与10.00.4064不匹配）而失败。
尝试2：导出和导入，验证错误等...没有从源到目标的副本
尝试3：（由于服务器不同而失败）

INSERT INTO [DB_NAME]..[dbo].[TABLE_NAME] 
     SELECT * FROM [DB_NAME]..[dbo].[TABLE_NAME]

（而不是像我这样使用的语法，它也有解析错误）

INSERT INTO [SERVER_NAME].[DB_NAME]..[dbo].[TABLE_NAME] 
SELECT * FROM [SERVER_NAME].[DB_NAME]..[dbo].[TABLE_NAME]

有很多方法可以做到这一点 -

<强> 1。通过此脚本生成CVS并导出数据（它适用于任何表结构）：

DECLARE 
      @TableName SYSNAME
    , @ObjectID INT

DECLARE [tables] CURSOR READ_ONLY FAST_FORWARD LOCAL FOR 
    SELECT 
          '[' + s.name + '].[' + t.name + ']'
        , t.[object_id]
    FROM (
        SELECT DISTINCT
              t.[schema_id]
            , t.[object_id]
            , t.name
        FROM sys.objects t WITH (NOWAIT)
        JOIN sys.partitions p WITH (NOWAIT) ON p.[object_id] = t.[object_id]
        WHERE p.[rows] > 0
            AND t.[type] = 'U'
    ) t
    JOIN sys.schemas s WITH (NOWAIT) ON t.[schema_id] = s.[schema_id]
    WHERE t.name IN ('<your_table_name>')

OPEN [tables]

FETCH NEXT FROM [tables] INTO 
      @TableName
    , @ObjectID

DECLARE 
      @SQLInsert NVARCHAR(MAX)
    , @SQLColumns NVARCHAR(MAX)
    , @SQLTinyColumns NVARCHAR(MAX)

WHILE @@FETCH_STATUS = 0 BEGIN

    SELECT 
          @SQLInsert = ''
        , @SQLColumns = ''
        , @SQLTinyColumns = ''

    ;WITH cols AS 
    (
        SELECT 
              c.name
            , datetype = t.name
            , c.column_id
        FROM sys.columns c WITH (NOWAIT)
        JOIN sys.types t WITH (NOWAIT) ON c.system_type_id = t.system_type_id AND c.user_type_id = t.user_type_id
        WHERE c.[object_id] = @ObjectID
            AND c.is_computed = 0
            AND t.name NOT IN ('xml', 'geography', 'geometry', 'hierarchyid')
    )
    SELECT 
          @SQLTinyColumns = STUFF((
            SELECT ', [' + c.name + ']'
            FROM cols c
            ORDER BY c.column_id
            FOR XML PATH, TYPE, ROOT).value('.', 'NVARCHAR(MAX)'), 1, 2, '')
        , @SQLColumns = STUFF((SELECT CHAR(13) +
            CASE 
                WHEN c.datetype = 'uniqueidentifier' 
                    THEN ' + '';'' + ISNULL('''' + CAST([' + c.name + '] AS VARCHAR(MAX)) + '''', ''NULL'')' 
                WHEN c.datetype IN ('nvarchar', 'varchar', 'nchar', 'char', 'varbinary', 'binary')

                ELSE 
                ' + '';'' + ISNULL(CAST([' + c.name + '] AS NVARCHAR(MAX)), ''NULL'')'
            END
            FROM cols c
            ORDER BY c.column_id
            FOR XML PATH, TYPE, ROOT).value('.', 'NVARCHAR(MAX)'), 1, 10, 'CHAR(13) + '''' +')

    DECLARE @SQL NVARCHAR(MAX) = '    
    SET NOCOUNT ON;
    DECLARE 
          @SQL NVARCHAR(MAX) = ''''
        , @x INT = 1
        , @count INT = (SELECT COUNT(1) FROM ' + @TableName + ')

    IF EXISTS(
        SELECT 1
        FROM tempdb.dbo.sysobjects
        WHERE ID = OBJECT_ID(''tempdb..#import'')
    )
        DROP TABLE #import;

    SELECT ' + @SQLTinyColumns + ', ''RowNumber'' = ROW_NUMBER() OVER (ORDER BY ' + @SQLTinyColumns + ')
    INTO #import
    FROM ' + @TableName + ' 

    WHILE @x < @count BEGIN

        SELECT @SQL = STUFF((
        SELECT ' + @SQLColumns + ' + ''''' + '
        FROM #import 
        WHERE RowNumber BETWEEN @x AND @x + 9
        FOR XML PATH, TYPE, ROOT).value(''.'', ''NVARCHAR(MAX)''), 1, 1, '''')

        PRINT(@SQL)

        SELECT @x = @x + 10

    END'

    EXEC sys.sp_executesql @SQL

    FETCH NEXT FROM [tables] INTO 
          @TableName
        , @ObjectID

END

CLOSE [tables]
DEALLOCATE [tables]

的输出： 的

第3。使用任何数据比较器，例如： dbForge Data Compare for SQL Server

<强> 4。使用链接的服务器： MSDN

Answer 2

您可以将源数据库设置为目标数据库上的Linked Server

然后只在目标数据库上执行：

SELECT * INTO [TABLE_NAME] FROM [SOURCEDB]..[dbo].[TABLE_NAME]

此命令创建表结构并插入从源到目标的所有行。

如果您需要传输索引，约束，....您可以在MS SQL服务器中使用“生成脚本”企业管理器界面命令。

同样在SQL 2008上，您可以使用包含数据的generate script interface命令。因此，您只需要在源数据库上为您的表生成脚本，并在目标数据库上运行此脚本。以下是一些链接：
