--当用以下代码创建一个表后，如何根据表名查询出创建该表的代码(也就是以下代码)？
CREATE TABLE [dbo].[a1](
[c2] [decimal](10, 2) NULL,
[c3] [decimal](10, 3) NULL CONSTRAINT [DF_a1_c3] DEFAULT ((0)),
[re] [bigint] IDENTITY(1,1) NOT NULL,
CONSTRAINT [PK_a1] PRIMARY KEY CLUSTERED
(
[re] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
------解决方案--------------------
用这个语句可以：
declare @sql varchar(8000),@tablename varchar(100)
set @tablename ='a1'--这里输入表名
set @sql = 'create table ['+@tablename+']
(
'
select @sql = @sql + b.name + ' '+
c.name+
case when c.collation_name is not null then '('+
case when b.max_length <>-1 then convert(varchar(100),b.max_length)
else 'MAX'
end +') '
else ''
end +
case when b.is_identity = 1 then ' identity('+convert(varchar(100),IDENT_SEED(@tablename))+','+convert(varchar(100),IDENT_INCR(@tablename))+')' else '' end +
case when d.definition is not null then ' default('+d.definition +')' else '' end +
case when b.is_nullable = 0 then ' not null' else ' null' end +
',
'
from sys.objects a join sys.columns b
on a.object_id = b.object_id
join sys.types c
on b.system_type_id = c.system_type_id and b.user_type_id = c.user_type_id
left join sys.default_constraints d
on b.default_object_id = d.object_id
where a.name=@tablename
order by b.column_id
if exists(select * from sys.indexes where object_id =object_id(@tablename) and is_primary_key =1 )
begin
select @sql = @sql + 'CONSTRAINT ['+name+'] PRIMARY KEY '+type_desc+'
(
' from sys.indexes where object_id =object_id(@tablename) and is_primary_key =1
select @sql = @sql + b.name + case when a.is_descending_key =1 then ' DESC' else ' ASC' end +',
' from sys.index_columns a join sys.columns b
on a.object_id= b.object_id and a.column_id = b.column_id
where a.object_id =object_id(@tablename)
select @sql = left(@sql,len(@sql)-3)+'
)'
select @sql = @sql+'
) ON [PRIMARY] '
end
else
begin
select @sql = left(@sql,len(@sql)-1)+'
) ON [PRIMARY] '
end
print @sql
/*
create table [a1]
(
c2 decimal null,
c3 decimal default(((0))) null,
re bigint identity(1,1) not null,
CONSTRAINT [PK_a1] PRIMARY KEY CLUSTERED
(
re ASC
)
) ON [PRIMARY]

用C#http://www.mssqltips.com/sqlservertip/1833/generate-scripts-for-database-objects-with-smo-for-sql-server/

假设条件允许------解决方案--------------------
表的创建语句是通过系统表或视图动态生成的。
这个跟procdure\function之类不一样， 这些可以存在syscomments里。
------解决方案--------------------
用SQL Prompt等工具吧
