sql server 数据库导出表里所有数据成 insert 语句
有时候，我们想把数据库的某张表里的所有数据导入到另外一个数据库或另外一台计算机上的数据库，对于sql server有这样的一种方法
下面我以sql server 2008 R2,数据库是Northwind数据库为例，
目标：把Northwind数据库的Orders表导出成insert语句。
第一步：选择Northwind数据库，右键-任务-生成脚本：
第二步：在弹出的“生成和发布脚本”的简介窗口，按“下一步”按钮：
第三步：在“选择对象”窗口，选中“选择特定数据库对象”，展开表，
勾选要生成insert语句的表，我这里选的是order表，
按“下一步”按钮：
第四步：在弹出的“设置脚本编写选项”窗口，按“高级”按钮，
在弹出的“高级脚本编写选项”中下拉下拉条至底部，
设置“要编写脚本的数据类型”为“仅限数据”(“仅限数据”是只导出数据为insert语句，如果是导出表结构的话选择“仅限架构”，选择“架构和数据”则架构和insert语句都生成)，按“确定”按钮：
第五步：在“设置脚本编写选项”窗口，
“指定如何保存或发布脚本”的“输出类型”选中“将脚本保存到特定位置”,
勾选“保存到文件”，则可以指定一个保存的路径，保存为.sql文件，
勾选“保存到新建查询窗口”，则会新打开一个查询窗口，把所有insert 语句放到新查询窗口：
第六步：在“设置脚本编写选项”窗口，按“下一步”按钮，弹出：
第七步：在“摘要”窗口，按“下一步”按钮：
第八步：在“保存或发布脚本”窗口，按“完成”按钮：
最终会自动新建一个查询窗口，order表里的所有数据都转换成insert语句。

将表里的数据批量生成INSERT语句的存储过程 增强版
有时候，我们需要将某个表里的数据全部或者根据查询条件导出来，迁移到另一个相同结构的库中
目前SQL Server里面是没有相关的工具根据查询条件来生成INSERT语句的，只有借助第三方工具（third party tools）
这种脚本网上也有很多，但是网上的脚本还是欠缺一些规范和功能，例如：我只想导出特定查询条件的数据，网上的脚本都是导出全表数据
如果表很大，对性能会有很大影响
这里有一个存储过程（适用于SQLServer2005 或以上版本）

这里要声明一下，如果你有多个schema，并且每个schema下面都有同一张表，那么脚本只会生成其中一个schema下面的表insert脚本
比如我现在有三个schema，下面都有customer这个表
CREATE TABLE dbo.[customer](city int,region int) CREATE SCHEMA test CREATE TABLE test.[customer](city int,region int) CREATE SCHEMA test1 CREATE TABLE test1.[customer](city int,region int)
在执行脚本的时候他只会生成dbo这个schema下面的表insert脚本
INSERT INTO [dbo].[customer]([city],[region]) VALUES(\'1\',\'2\')
这个脚本有一个缺陷
无论你的表的字段是什麽数据类型，导出来的时候只能是字符
表结构
CREATE TABLE [dbo].[customer](city int,region int)
导出来的insert脚本
INSERT INTO [dbo].[customer]([city],[region]) VALUES(\'1\',\'2\')
我这里演示一下怎麽用
有两种方式
1、导全表数据
InsertGenerator \'customer\', null
或
InsertGenerator \'customer\', \' \'
2、根据查询条件导数据
InsertGenerator \'customer\', \'city=3\'
或者
InsertGenerator \'customer\', \'city=3 and region=8\'
点击一下，选择全部
然后复制
新建一个查询窗口，然后粘贴
其实SQLServer的技巧有很多
最后，大家可以看一下代码，非常简单，如果要支持SQLServer2000，只要改一下代码就可以了
补充：创建一张测试表
CREATE TABLE testinsert (id INT,name VARCHAR(100),cash MONEY,dtime DATETIME) INSERT INTO [dbo].[testinsert] ( [id], [name], [cash], [dtime] ) VALUES ( 1, -- id - int \'nihao\', -- name - varchar(100) 8.8, -- cash - money GETDATE() -- dtime - datetime ) SELECT * FROM [dbo].[testinsert]
测试
InsertGenerator \'testinsert\' ,\'\' InsertGenerator \'testinsert\' ,\'name=\'\'nihao\'\'\' InsertGenerator \'testinsert\' ,\'name=\'\'nihao\'\' and cash=8.8\'
datetime类型会有一些问题
生成的结果会自动帮你转换
INSERT INTO [dbo].[testinsert]([id],[name],[cash],[dtime]) VALUES(\'1\',\'nihao\',convert(money,\'8.80\'),convert(datetime,\'02 8 2015 5:17PM\'))
群里的人共享的另一个脚本
