delphi - How to remove duplicate records in grid? -

-

Good morning!

What is the best way to remove duplicate records from grid control? I use the Delphi 200 9 and the Dvx Quantum Grid component.

I tried looping through all the records and when a duplicate record was found, add it to the list and apply the filter to the grid. There is also two downsides of this approach that I got as a logic of taking this time.

[1] When duplicate records are high enough, it takes a lot of time to apply filter after 10K record, because many entries to filter.

[2] Looping through all records only takes time to set big results like 1M rows.

SQL queries give me different rows, but when the user hides any of the columns in the grid, it looks as if there are duplicate records (they are internally intact).

Is there any other way to do this?

Any ideas on this are very useful!

Thanks & amp; Regards, Pawan.

With thousands of rows I will add an additional area to DB, which is said to be yoga or hash Or if you can not change a count field to DB, if this client is a data set but it overheads the display time

Calculate the contents of the hash field with any type of fast and simple things. All enemies in the text field are now easily recognizable . Add or filter this field in your unique or specific query parameters.

Just an Idea

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
