我修改了上面的版本以運行所有表並支持新的SQL 2005數據類型。它還保留了主鍵名稱。僅適用於SQL 2005（使用交叉應用）。


select 'create table [' + so.name + '] (' + o.list + ')' + CASE WHEN tc.Constraint_Name IS NULL THEN '' ELSE 'ALTER TABLE ' + so.Name + ' ADD CONSTRAINT ' + tc.Constraint_Name + ' PRIMARY KEY ' + ' (' + LEFT(j.List, Len(j.List)-1) + ')' END 
from sysobjects so 
cross apply 
    (SELECT 
     ' ['+column_name+'] ' + 
     data_type + case data_type 
      when 'sql_variant' then '' 
      when 'text' then '' 
      when 'ntext' then '' 
      when 'xml' then '' 
      when 'decimal' then '(' + cast(numeric_precision as varchar) + ', ' + cast(numeric_scale as varchar) + ')' 
      else coalesce('('+case when character_maximum_length = -1 then 'MAX' else cast(character_maximum_length as varchar) end +')','') end + ' ' + 
     case when exists ( 
     select id from syscolumns 
     where object_name(id)=so.name 
     and name=column_name 
     and columnproperty(id,name,'IsIdentity') = 1 
     ) then 
     'IDENTITY(' + 
     cast(ident_seed(so.name) as varchar) + ',' + 
     cast(ident_incr(so.name) as varchar) + ')' 
     else '' 
     end + ' ' + 
     (case when IS_NULLABLE = 'No' then 'NOT ' else '' end) + 'NULL ' + 
      case when information_schema.columns.COLUMN_DEFAULT IS NOT NULL THEN 'DEFAULT '+ information_schema.columns.COLUMN_DEFAULT ELSE '' END + ', ' 

    from information_schema.columns where table_name = so.name 
    order by ordinal_position 
    FOR XML PATH('')) o (list) 
left join 
    information_schema.table_constraints tc 
on tc.Table_name  = so.Name 
AND tc.Constraint_Type = 'PRIMARY KEY' 
cross apply 
    (select '[' + Column_Name + '], ' 
    FROM information_schema.key_column_usage kcu 
    WHERE kcu.Constraint_Name = tc.Constraint_Name 
    ORDER BY 
     ORDINAL_POSITION 
    FOR XML PATH('')) j (list) 
where xtype = 'U' 
AND name NOT IN ('dtproperties')

更新：對XML數據類型

更新2的添加處理：固定例1）存在具有相同名稱但具有不同的架構的多個表的情況下，2）有多個具有PK約束的表具有相同的名稱

這是我想出的腳本。它處理標識列，默認值和主鍵。它不處理外鍵，索引，觸發器或任何其他聰明的東西。它適用於SQLServer 2000,2005和2008.

declare @table varchar(100) 
set @table = 'MyTable' -- set table name here 
declare @sql table(s varchar(1000), id int identity) 

-- create statement 
insert into @sql(s) values ('create table [' + @table + '] (') 

-- column list 
insert into @sql(s) 
select 
    ' ['+column_name+'] ' + 
    data_type + coalesce('('+cast(character_maximum_length as varchar)+')','') + ' ' + 
    case when exists ( 
     select id from syscolumns 
     where object_name(id)[email protected] 
     and name=column_name 
     and columnproperty(id,name,'IsIdentity') = 1 
    ) then 
     'IDENTITY(' + 
     cast(ident_seed(@table) as varchar) + ',' + 
     cast(ident_incr(@table) as varchar) + ')' 
    else '' 
    end + ' ' + 
    (case when IS_NULLABLE = 'No' then 'NOT ' else '' end) + 'NULL ' + 
    coalesce('DEFAULT '+COLUMN_DEFAULT,'') + ',' 

from INFORMATION_SCHEMA.COLUMNS where table_name = @table 
order by ordinal_position 

-- primary key 
declare @pkname varchar(100) 
select @pkname = constraint_name from INFORMATION_SCHEMA.TABLE_CONSTRAINTS 
where table_name = @table and constraint_type='PRIMARY KEY' 

if (@pkname is not null) begin 
    insert into @sql(s) values(' PRIMARY KEY (') 
    insert into @sql(s) 
     select ' ['+COLUMN_NAME+'],' from INFORMATION_SCHEMA.KEY_COLUMN_USAGE 
     where constraint_name = @pkname 
     order by ordinal_position 
    -- remove trailing comma 
    update @sql set s=left(s,len(s)-1) where [email protected]@identity 
    insert into @sql(s) values (' )') 
end 
else begin 
    -- remove trailing comma 
    update @sql set s=left(s,len(s)-1) where [email protected]@identity 
end 

-- closing bracket 
insert into @sql(s) values(')') 

-- result! 
select s from @sql order by id

大量的系統將不能夠因爲這個運行動態SQL 。在你的本地盒子上可能不是問題，但只是想指出。 – 2008-10-10 01:15:42

什麼是動態sql？這個腳本生成sql - 它不執行它。 – Blorgbeard 2008-10-15 23:57:47

很希望看到這個分解成步驟，因此可以用一系列可以用C++編寫的查詢來執行。 – 2011-04-30 08:58:41

因@Blorgbeard分享他的腳本而致。我一定會收藏它，以防我需要它。

是的，你可以在「右鍵」在桌子上，腳本CREATE TABLE腳本，但：（？感興趣的擴展屬性的人）

  • 該腳本將包含負載克魯夫特的
  • 如果您的架構中有超過200個表格，則需要半天時間手動編寫該表格。

有了這個腳本轉換成一個存儲過程，並用包裝腳本相結合，你將有一個很好的自動化的方式來轉儲你的表設計成源控制等

你的數據庫代碼的其餘部分（SP的，FK索引，觸發器等）無論如何都會受到源代碼控制;）

我注意到的一些東西 - 在INFORMATION_SCHEMA.COLUMNS視圖中，CHARACTER_MAXIMUM_LENGTH給出字段類型的大小2147483647（2^31-1），例如圖像和文字。 ntext是2^30-1（是雙字節unicode和全部）。

該大小包含在此查詢的輸出中，但它對於CREATE語句中的這些數據類型無效（它們不應具有最大大小值）。因此，除非手動更正這些結果，否則CREATE腳本將無法使用這些數據類型。

我想可以修復腳本來解決這個問題，但這超出了我的SQL功能。

如果您正在使用management studio並打開查詢分析器窗口，則可以將表名稱拖動到查詢分析器窗口並... bingo！你得到表格腳本。 我還沒有在SQL2008中試過這個

如果您正在生成腳本的應用程序是.NET應用程序，則可能需要使用SMO（Sql管理對象）進行調查。參考SQL Team link關於如何使用SMO來編寫腳本對象。

Show create table in classic asp（處理約束，主鍵，複製表結構和/或數據...）

不要痛打這一點，但這裏的功能相當的例子輸出進行比較：

-- 1 (scripting version) 
create table [dbo].[ASPStateTempApplications] ( [AppId] int NOT NULL , [AppName] char(280) NOT NULL); ALTER TABLE [dbo].[ASPStateTempApplications] ADD CONSTRAINT PK__ASPState__8E2CF7F908EA5793 PRIMARY KEY ([AppId]); 

-- 2 (SSMS version) 
create table [dbo].[ASPStateTempSessions] (
    [SessionId] nvarchar(88) NOT NULL , 
    [Created] datetime NOT NULL DEFAULT (getutcdate()), 
    [Expires] datetime NOT NULL , 
    [LockDate] datetime NOT NULL , 
    [LockDateLocal] datetime NOT NULL , 
    [LockCookie] int NOT NULL , 
    [Timeout] int NOT NULL , 
    [Locked] bit NOT NULL , 
    [SessionItemShort] varbinary(7000) NULL , 
    [SessionItemLong] image(2147483647) NULL , 
    [Flags] int NOT NULL DEFAULT ((0)) 
); 
ALTER TABLE [dbo].[ASPStateTempSessions] ADD CONSTRAINT PK__ASPState__C9F4929003317E3D PRIMARY KEY ([SessionId]);

..

減損因素：

應當指出的是，我仍然相對不滿意這種由於缺乏比主鍵等的indeces支持。它仍然適合用作簡單數據導出或複製的機制。

我會通過支持分區表，提高了答案：

查找分區方案和分區鍵使用以下scritps：

declare @partition_scheme varchar(100) = (
select distinct ps.Name AS PartitionScheme 
from sys.indexes i 
join sys.partitions p ON i.object_id=p.object_id AND i.index_id=p.index_id 
join sys.partition_schemes ps on ps.data_space_id = i.data_space_id 
where i.object_id = object_id('your table name') 
) 
print @partition_scheme 

declare @partition_column varchar(100) = (
select c.name 
from sys.tables   t 
join sys.indexes   i 
     on(i.object_id = t.object_id 
    and i.index_id < 2) 
join sys.index_columns ic 
    on(ic.partition_ordinal > 0 
    and ic.index_id = i.index_id and ic.object_id = t.object_id) 
join sys.columns   c 
    on(c.object_id = ic.object_id 
    and c.column_id = ic.column_id) 
where t.object_id = object_id('your table name') 
) 
print @partition_column

然後改變一代查詢通過添加以下行在正確的地方：

+ IIF(@partition_scheme is null, '', 'ON [' + @partition_scheme + ']([' + @partition_column + '])')

我意識到這是一個很長的時間，但我想我會加上反正。如果你只是想表，而不是創建表語句，你可以使用

select into x from db.schema.y where 1=0

表複製到新的DB
