我们正在编写一个新的应用程序，在进行测试时，我们将需要一堆虚拟数据。我已经通过使用MS Access将excel文件转储到相关表中添加了这些数据。
每隔一段时间，我们想要“刷新”相关的表，这意味着将它们全部删除，重新创建它们，并运行已保存的MS Access追加查询。
第一部分(删除和重新创建)是一个简单的sql脚本，但最后一部分让我畏缩。我想要一个单独的设置脚本，它有一堆insert来重新生成虚拟数据。
我现在有数据在表格里。从该数据集自动生成一个大的INSERT语句列表的最佳方法是什么?
我能想到的唯一方法是将表保存到excel表格中，然后编写excel公式为每一行创建一个INSERT，这肯定不是最好的方法。
我使用2008 Management Studio连接到SQL Server 2005数据库。
当前回答
为了获得带有过滤记录的INSERT语句(WHERE QUERY)，您可以
右击表脚本表>创建到>新的查询 用temp_table重命名 现在运行 选择到temp_table从你的第一个表，现在你的标准在这里
这样你的临时表将只有你想要的记录， 现在通过运行由@Mike Ritacco with DATA ONLY解释的脚本向导，您将得到确切的插入语句。
其他回答
我使用的是SSMS 2008版本10.0.5500.0。在这个版本中，作为生成脚本向导的一部分，下面是一个屏幕，而不是一个高级按钮。在本例中，我只想插入数据而不需要create语句，因此必须更改两个圈起来的属性
我们使用这个存储过程——它允许您针对特定的表，并使用where子句。你可以在这里找到文本。
例如，它可以让你这样做:
EXEC sp_generate_inserts 'titles'

Procedure: sp_generate_inserts (Build 22)
(Copyright © 2002 Narayana Vyas Kondreddi. All rights reserved.)
Purpose: To generate INSERT statements from existing data.
These INSERTS can be executed to regenerate the data at some other location.
This procedure is also useful to create a database setup, where in you can
script your data along with your table definitions.

NOTE: This procedure may not work with tables with too many columns.
Results can be unpredictable with huge text columns or SQL Server 2000's sql_variant data types
Whenever possible, Use @include_column_list parameter to ommit column list in the INSERT statement, for better results
IMPORTANT: This procedure is not tested with internation data (Extended characters or Unicode). If needed
you might want to convert the datatypes of character variables in this procedure to their respective unicode counterparts
like nchar and nvarchar
Example 1: To generate INSERT statements for table 'titles':
EXEC sp_generate_inserts 'titles'
Example 2: To ommit the column list in the INSERT statement: (Column list is included by default)
IMPORTANT: If you have too many columns, you are advised to ommit column list, as shown below,
to avoid erroneous results
EXEC sp_generate_inserts 'titles', @include_column_list = 0
Example 3: To generate INSERT statements for 'titlesCopy' table from 'titles' table:
EXEC sp_generate_inserts 'titles', 'titlesCopy'
Example 4: To generate INSERT statements for 'titles' table for only those titles
which contain the word 'Computer' in them:
NOTE: Do not complicate the FROM or WHERE clause here. It's assumed that you are good with T-SQL if you are using this parameter
EXEC sp_generate_inserts 'titles', @from = "from titles where title like '%Computer%'"
Example 5: To specify that you want to include TIMESTAMP column's data as well in the INSERT statement:
(By default TIMESTAMP column's data is not scripted)
EXEC sp_generate_inserts 'titles', @include_timestamp = 1
Example 6: To print the debug information:
EXEC sp_generate_inserts 'titles', @debug_mode = 1
Example 7: If you are not the owner of the table, use @owner parameter to specify the owner name
To use this option, you must have SELECT permissions on that table
EXEC sp_generate_inserts Nickstable, @owner = 'Nick'
Example 8: To generate INSERT statements for the rest of the columns excluding images
When using this otion, DO NOT set @include_column_list parameter to 0.
EXEC sp_generate_inserts imgtable, @ommit_images = 1
Example 9: To generate INSERT statements excluding (ommiting) IDENTITY columns:
(By default IDENTITY columns are included in the INSERT statement)
EXEC sp_generate_inserts mytable, @ommit_identity = 1
Example 10: To generate INSERT statements for the TOP 10 rows in the table:
EXEC sp_generate_inserts mytable, @top = 10
Example 11: To generate INSERT statements with only those columns you want:
EXEC sp_generate_inserts titles, @cols_to_include = "'title','title_id','au_id'"
Example 12: To generate INSERT statements by omitting certain columns:
EXEC sp_generate_inserts titles, @cols_to_exclude = "'title','title_id','au_id'"
Example 13: To avoid checking the foreign key constraints while loading data with INSERT statements:
EXEC sp_generate_inserts titles, @disable_constraints = 1
Example 14: To exclude computed columns from the INSERT statement:
EXEC sp_generate_inserts MyTable, @ommit_computed_cols = 1

上面有许多用于生成插入语句的好脚本，但我尝试了自己的一个脚本，以使其尽可能对用户友好，并能够执行UPDATE语句。+将结果打包为可按日期存储的.sql文件。
它以带有WHERE子句的普通SELECT语句作为输入，然后输出一个Insert语句和update语句列表。它们一起形成了一种IF NOT EXISTS () INSERT ELSE UPDATE当有不可更新的列需要从最后的INSERT/UPDATE语句中排除时，这也很方便。
下面的脚本可以做的另一件事是:它甚至可以处理与其他表的INNER join，作为存储过程的输入语句。它可以作为一个穷人的发布管理工具，在你整天键入sql SELECT语句的时候，它就在你的指尖。

(REMARK about above: the use of # in front of a column name (so #abc) can do an update of that columname (abc) with any column from an inner joined table where you use the alias #abc )
-------------README for the deeper interested person:
Goal of the Stored PROCEDURE is to get updates from simple SQL SELECT statements. It is made ot be simple but fast and powerfull. As always => power is nothing without control, so check before you execute.
Its power sits also in the fact that you can make insert statements, so combined gives you a "IF NOT EXISTS() INSERT " capability.
The scripts work were there are primary keys or identity columns on table you want to update (/ or make inserts for).
It will also works when no primary keys / identity column exist(s) and you define them yourselve. But then be carefull (duplicate hits can occur). When the table has a primary key it will always be used.
The script works with a real temporary table, made on the fly (APPROPRIATE RIGHTS needed), to put the values inside from the script, then add 3 columns for constructing the "insert into tableX (...) values ()" , and the 2 update statement.
We work with temporary structures like "where columnname = {Columnname}" and then later do the update on that temptable for the columns values found on that same line.
example "where columnname = {Columnname}" for birthdate becomes "where birthdate = {birthdate}" an then we find the birthdate value on that line inside the temp table.
So then the statement becomes "where birthdate = {19800417}"

为什么不只是在使用数据之前备份数据，然后在需要刷新数据时进行恢复呢?
如果必须生成插入，请尝试:http://vyaskn.tripod.com/code.htm#inserts
我做了一个简单易用的实用程序，希望你喜欢。
它不需要在数据库上创建任何对象(易于在生产环境中使用)。 你不需要安装任何东西。这只是一个普通的脚本。 您不需要特殊权限。常规的读访问就足够了。 允许您复制表的所有行，或指定WHERE条件，以便只生成您想要的行。 允许您指定要生成的单个或多个表和不同的条件语句。
如果生成的INSERT语句被截断，在Management Studio Options: Tools > Options, Query results > SQL Server > results to Grid，“Non XML data”value下的“Maximum Characters retrieve”中检查结果的限制文本长度。
