通常情况下,SQL Server里面的生成SQL脚本,只会包含数据库及表的字段结构,而不会包含表的数据,也就是SQL脚本里面只有Create database,Create table 这样的语句,没有insert into。
因为SQL Server并不包含这个功能,只能靠第三方的代码了。
以下存储过程可以实现:
CREATE PROCEDURE dbo.UspOutputData
@tablename sysname
AS
declare @column varchar ( 1000 )
declare @columndata varchar ( 1000 )
declare @sql varchar ( 4000 )
declare @xtype tinyint
declare @name sysname
declare @objectId int
declare @objectname sysname
declare @ident int
set nocount on
set @objectId = object_id ( @tablename )
if @objectId is null -- 判断对象是否存在
begin
print ' The object not exists '
return
end
set @objectname = rtrim ( object_name ( @objectId ))
if @objectname is null or charindex ( @objectname , @tablename ) = 0 -- 此判断不严密
begin
print ' object not in current database '
return
end
if OBJECTPROPERTY ( @objectId , ' IsTable ' ) < > 1 -- 判断对象是否是table
begin
print ' The object is not table '
return
end
select @ident = status & 0x80 from syscolumns where id = @objectid and status & 0x80 = 0x80
if @ident is not null
print ' SET IDENTITY_INSERT ' + @TableName + ' ON '
declare syscolumns_cursor cursor
for select c.name,c.xtype from syscolumns c where c.id = @objectid order by c.colid
open syscolumns_cursor
set @column = ''
set @columndata = ''
fetch next from syscolumns_cursor into @name , @xtype
while @@fetch_status < >- 1
begin
if @@fetch_status < >- 2
begin
if @xtype not in ( 189 , 34 , 35 , 99 , 98 ) -- timestamp不需处理,image,text,ntext,sql_variant 暂时不处理
begin
set @column = @column + case when len ( @column ) = 0 then '' else ' , ' end + @name
set @columndata = @columndata + case when len ( @columndata ) = 0 then '' else ' , '' , '' , '
end
+ case when @xtype in ( 167 , 175 ) then ''''''''' + ' + @name + ' + ''''''''' -- varchar,char
when @xtype in ( 231 , 239 ) then ''' N '''''' + ' + @name + ' + ''''''''' -- nvarchar,nchar
when @xtype = 61 then ''''''''' +convert(char(23), ' + @name + ' ,121)+ ''''''''' -- datetime
when @xtype = 58 then ''''''''' +convert(char(16), ' + @name + ' ,120)+ ''''''''' -- smalldatetime
when @xtype = 36 then ''''''''' +convert(char(36), ' + @name + ' )+ ''''''''' -- uniqueidentifier
else @name end
end
end
fetch next from syscolumns_cursor into @name , @xtype
end
close syscolumns_cursor
deallocate syscolumns_cursor
set @sql = ' set nocount on select '' insert ' + @tablename + ' ( ' + @column + ' ) values( '' as '' -- '' , ' + @columndata + ' , '' ) '' from ' + @tablename
print ' -- ' + @sql
exec ( @sql )
if @ident is not null
print ' SET IDENTITY_INSERT ' + @TableName + ' OFF '
GO
使用方法:
exec UspOutputData 你的表名
选择【执行模式】为“以文本显示结果”,然后将运行后的结果存成.sql,加上用SQL Server生成的数据库脚本就可以了。
另外可以利用第三方工具,导出数据可以用powerbuilder。在database painter里面,用SQL选出,或者直接打开表,点击生成的list datawindow,然后在菜单file->save rows as->选择SQL,那么生成的SQL语句就包括建表和insert数据的SQL了。
