VBA - 从电子表格的内容创建 ADODB.Recordset
我正在开发一个查询 SQL 数据库的 Excel 应用程序。查询可能需要很长时间才能运行(20-40 分钟)。如果我错误编码了某些内容,可能需要很长时间才能出错或达到断点。我可以将结果保存到一张纸上,但当我处理记录集时,事情可能会崩溃。
当我调试以跳过查询数据库(第一次之后)时,有没有办法将数据加载到 ADODB.Recordset 中?
我会用这样的东西吗?
I am working on an Excel application that queries a SQL database. The queries can take a long time to run (20-40 min). If I've miss-coded something it can take a long time to error or reach a break point. I can save the results to a sheet fine, it's when I am working with the record sets that things can blow up.
Is there a way to load the data into a ADODB.Recordset when I'm debugging to skip querying the database (after the first time)?
Would I use something like this?
Query Excel worksheet in MS-Access VBA (using ADODB recordset)

我必须安装 MDAC 才能获取 msado15.dll,一旦获得它,我就添加了对它的引用(在 Win7 64 位上):
C:\Program Files (x86)\Common Files\System\ado\msado15.dll
然后我创建了一个函数,通过传入当前活动工作簿中存在的工作表名称来返回 ADODB.Recordset 对象。如果其他人需要的话,这里是代码,包括 Test() Sub 来查看它是否有效:
Sheet1 数据:
字段 1 字段 2 字段 3
红A 1
蓝色B 2
绿色 C 3
应复制到 Sheet2 的内容:
红A 1
蓝色B 2
Green C 3
每次我想要进行更改并测试它时,这都为我节省了大量的 SQL 查询时间...--

I had to install the MDAC to get the msado15.dll and once I had it I added a reference to it from (on Win7 64bit):
C:\Program Files (x86)\Common Files\System\ado\msado15.dll
Then I created a function to return an ADODB.Recordset object by passing in a sheet name that exists in the currently active workbook. Here's the code for any others if they need it, including a Test() Sub to see if it works:
The Sheet1 data:
Field1 Field2 Field3
Red A 1
Blue B 2
Green C 3
What should be copied to Sheet2:
Red A 1
Blue B 2
Green C 3
This is saving me a HUGE amount of time from querying against SQL every time I want to make a change and test it out...

最简单的方法是使用 rs.Save "filename" 和 rs.Open "filename" 将客户端记录集序列化为文件。
Easiest would be to use
rs.Save "filename"
andrs.Open "filename"
to serialize client-side recordsets to files.从
Range
获取Recordset
的另一种方法是从目标Range
创建XMLDocument
并打开使用Range.Value()
属性从该文档获取Recordset
。如果您想使用上面的示例,请确保设置对
Microsoft ActiveX Data Objects 6.1 Library
和Microsoft XML, v6.0
的引用。如果需要,您还可以将此功能更改为后期绑定。调用示例
Another alternative to get a
Recordset
from aRange
would be to create andXMLDocument
from the targetRange
and open theRecordset
from that document using theRange.Value()
property.Make sure to set a reference to both
Microsoft ActiveX Data Objects 6.1 Library
andMicrosoft XML, v6.0
if you want to use the example above. You could also change this function to late binding if so desired.Example call
