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
我使用sqlite来做到这一点。我发现它对于创建scratch/test数据库非常非常有用。
sqlite3 foo。Sqlite .dump > foo_as_a_bunch_of_inserts.sql
其他回答
您可以使用SSMS Tools Pack(适用于SQL Server 2005和2008)。它带有一个生成插入语句的特性。
http://www.ssmstoolspack.com/
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。
在SQL Server中为特定的表生成UPDATE语句
CREATE PROCEDURE [dbo].[sp_generate_updates] (
@fullquery nvarchar(max) = '',
@ignore_field_input nvarchar(MAX) = '',
@PK_COLUMN_NAME nvarchar(MAX) = ''
)
AS
SET NOCOUNT ON
SET QUOTED_IDENTIFIER ON
/*
-- For Standard USAGE: (where clause is mandatory)
EXEC [sp_generate_updates] 'select * from dbo.mytable where mytext=''1'' '
OR
SET QUOTED_IDENTIFIER OFF
EXEC [sp_generate_updates] "select * from dbo.mytable where mytext='1' "
-- For ignoring specific columns (to ignore in the UPDATE and INSERT SQL statement)
EXEC [sp_generate_updates] 'select * from dbo.mytable where 1=1 ' , 'Column01,Column02'
-- For just updates without insert statement (replace the * )
EXEC [sp_generate_updates] 'select Column01, Column02 from dbo.mytable where 1=1 '
-- For tables without a primary key: construct the key in the third variable
EXEC [sp_generate_updates] 'select * from dbo.mytable where 1=1 ' ,'','your_chosen_primary_key_Col1,key_Col2'
-- For complex updates with JOINED tables
EXEC [sp_generate_updates] 'select o1.Name, o1.category, o2.name+ '_hello_world' as #name
from overnightsetting o1
inner join overnightsetting o2 on o1.name=o2.name
where o1.name like '%appserver%'
(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}"

Azure Data Studio -简单的数据脚本扩展。
插入…它生成每一行的UNION ALL SELECT。
Azure Data Studio UI是基于VSCode的，我发现它是直观和快速的，包括这个OSS扩展。
sp_generate_inserts的第一个链接非常酷，这是一个非常简单的版本:
DECLARE @Fields VARCHAR(max); SET @Fields = '[QueueName], [iSort]' -- your fields, keep []
DECLARE @Table VARCHAR(max); SET @Table = 'Queues' -- your table
DECLARE @SQL VARCHAR(max)
SET @SQL = 'DECLARE @S VARCHAR(MAX)
SELECT @S = ISNULL(@S + '' UNION '', ''INSERT INTO ' + @Table + '(' + @Fields + ')'') + CHAR(13) + CHAR(10) +
''SELECT '' + ' + REPLACE(REPLACE(REPLACE(@Fields, ',', ' + '', '' + '), '[', ''''''''' + CAST('),']',' AS VARCHAR(max)) + ''''''''') +' FROM ' + @Table + '
PRINT @S'
EXEC (@SQL)
在我的系统中，我得到了这样的结果:
INSERT INTO Queues([QueueName], [iSort])
SELECT 'WD: Auto Capture', '10' UNION
SELECT 'Car/Lar', '11' UNION
SELECT 'Scan Line', '21' UNION
SELECT 'OCR', '22' UNION
SELECT 'Dynamic Template', '23' UNION
SELECT 'Fix MICR', '41' UNION
SELECT 'Fix MICR (Supervisor)', '42' UNION
SELECT 'Foreign MICR', '43' UNION
...
不确定，如果我没理解错的话。
如果你有数据在MS-Access，你想把它移动到SQL Server -你可以使用DTS。 而且，我猜你可以使用SQL分析器来查看所有的INSERT语句。
