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。

也许你可以试试SQL Server发布向导 http://www.microsoft.com/downloads/details.aspx?FamilyId=56E5B1C5-BF17-42E0-A410-371A838E570A&displaylang=en

它有一个向导,帮助您编写插入语句。

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。

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

它有一个向导,帮助您编写插入语句。

你可以随心所欲地把它变得困难或简单。我更喜欢后者。

如果你已经有一个数据集,你所要做的就是在MS Access中添加一个动作查询:

insert into Table1("column list here")从Table2中选择"column list here"

注意:Table2可以是一个查询表,Table1和Table2可以是一个MS Access表或Sql Server表

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
