如何为包含所有存储行的现有 SQL Server 表生成 INSERT 脚本？

Question

我正在寻找一种使用 SQL Management Studio 2008 R2 生成“创建并插入所有行”脚本的方法。

我知道我可以创建一个“创建表”脚本。

我还可以创建一个“插入”脚本，但这只会生成带有占位符的单行。

有没有办法生成包含所有当前存储的行的插入脚本？

Answer 1

是的，但您需要在数据库级别运行它。

右键单击SSMS中的数据库，选择“任务”、“生成脚本...”。当您完成操作时，您将进入“脚本选项”部分。单击“高级”，在弹出的列表中显示“要编写脚本的数据类型”，您可以选择数据和/或架构。

Answer 2

该脚本生成现有数据的插入语句。这是一个存储过程，您需要运行一次，然后它就是为您量身定制的。

我尝试寻找这类东西一段时间，但对结果不满意，所以我编写了这个存储过程。

示例：

Exec [dbo].[INS]  'Dbo.test where 1=1'

(1) 这里 dbo 是模式，test 是表名，1=1 是条件。

Exec [dbo].[INS]  'Dbo.test where name =''neeraj''' * for string

(2) 这里dbo是模式，test是表名，name='neeraj'是条件。

这是存储过程

/*
Authore : neeraj prasad sharma (please dont remove this :))
Example (1) Exec [dbo].[INS]  'Dbo.test where 1=1'
        (2) Exec [dbo].[INS]  'Dbo.test where name =''neeraj''' * for string

here Dbo is schema and test is tablename and 1=1 is condition

是的，使用商业但便宜的 SSMS Tools Pack 插件，它有一个漂亮的“从结果集、表或生成插入语句”数据库”功能

Answer 4

只是为了分享，我开发了自己的脚本来做到这一点。请随意使用它。它生成“SELECT”语句，然后您可以在表上运行该语句以生成“INSERT”语句。
