sql server 儲存過程生成insert語句

你肯定有過這樣的煩惱，同樣的表，不同的資料庫，加入你不能執行select  insert

那麼你肯定需要一條這樣的儲存過程，之需要傳入表明，就會給你生成資料的插入語句。

當然資料表數量太大，你將最好用別的方式

create

proc
[dbo
].[spgeninsertsql
] (@tablename
varchar(256
))as
begin
declare
@sql
varchar(8000
)declare
@sqlvalues
varchar(8000
)set
@sql='
('set@sqlvalues='
values (''+
'select
@sqlvalues
=@sqlvalues
+ cols +'+ 
'',''+ 
' ,@sql
=@sql+'
['+ name +'],
'from
(select
case
when xtype in (48,52,56,59,60,62,104,106,108,122,127
) 
then
'case when 
'+ name +
'is null then 
''null
''else '+
'cast(
'+ name +
'as varchar)'+
'end
'when xtype in (58,61
) 
--then '''''''''+convert(char(23),'+name+',121)+''''''''' --datetime 
then
'case when 
'+ name +
'is null then 
''null
''else '+
'''''''''+ '
+'cast(
'+ name +
'as varchar)'+
'+'''''''''+'
end'
when xtype in (167
) 
then
'case when 
'+ name +
'is null then 
''null
''else '+
'''''''''+ '
+'replace(
'+ name+',
''''''''
,'''''''''''')'
+'+'''''''''+'
end'
when xtype in (231
) 
then
'case when 
'+ name +
'is null then 
''null
''else '+
'''n
''''''+ '
+'replace(
'+ name+',
''''''''
,'''''''''''')'
+'+'''''''''+'
end'
when xtype in (175
) 
then
'case when 
'+ name +
'is null then 
''null
''else '+
'''''''''+ '
+'cast(replace(
'+ name+',
''''''''
,''''''''''''
) as char('+
cast(length as
varchar) +
'))+
'''''''''+'
end'
when xtype in (239
) 
then
'case when 
'+ name +
'is null then 
''null
''else '+
'''n
''''''+ '
+'cast(replace(
'+ name+',
''''''''
,''''''''''''
) as char('+
cast(length as
varchar) +
'))+
'''''''''+'
end'
else
'''null
'''end
ascols,name
from
syscolumns 
where id =
object_id(@tablename
) ) t
set@sql='
select 
''insert into ['+
@tablename+'
]'+left(@sql,len(@sql)-
1)+') '
+left(@sqlvalues,len(@sqlvalues)-
4) +')
''from '+
@tablename
print
@sql
exec (@sql
)end

最後的結果：

insert into [syssample] ([id],[name],[age],[bir],[photo],[note],[createtime]) values ('0002ca83-af2f-4d8f-a345-33ca1cc7cf3c','任務排程系統',18,'2013-01-02 21:42:30.013','',null,'2013-01-02 21:42:30.013')
