How to compare a sql server table field with a csv field and display what is not in the sql table.

[Norris Chappell]

I tried to query it and got an error?

If that is the case why didn't I need to have it when I did the select on the "where not exists" query?

Sorry, I'm tired - now I think I understood what you meant: The DataAdapter on this line: dataAdapter.Fill(dataTable); opens the connection automatically if it isn't already, but cmd.ExecuteNonQuery(); doesn't, so after un-commenting that line it became neccessary to open the connection explicitly.

One more thing My perm table is called TempTable maybe I should create the temp table with a different name?

I think you're tired too ;) Yes, you should have renamed or deleted the perm table. (I actually don't know if it would be a problem, I just told you to do that to avoid a potential error.)

Quote:

Okay didn't get the error. However, I don't see the table in SQL Server?

It's a temporary table. It exists only during the lifetime of the connection and is only visible to that connection.

Always tell the exact error message when you're trying to get help :)

Sorry again. You are right I am tired too. I think I am good for now. I can figure out the hours issue. You have been so helpful and I have learn a lot from you. Thank you for being so patience with me. What time zone are you in? Are you from France?

[Sascha Lefevre]

You're welcome! But if you can't figure out the hours issue, feel free to ask. I'm from Germany, one of my ancestors came from France :) Good luck and good night! cheers, Sascha

I need to replace: using (StreamReader reader = File.OpenText(@"c:\Users\pzd74f\Downloads\TestLabor2015.csv")) with something like this: protected void ImportButton_Click(object sender, EventArgs e) { if (this.FileUpload1.HasFile) { var extension = Path.GetExtension(FileUpload1.FileName); if (extension == ".csv") { StreamReader csvreader = new StreamReader(FileUpload1.FileContent); I need to have the user to be able to import the file instead of the csv be hardcoded.

[Sascha Lefevre]

Just pass FileUpload1.FileContent as an argument to QueryStaff :)

I tried to pass as an argument but getting errors: c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\CONTROLTEMPLATES\StaffingWebParts\VisualWebPart1\VisualWebPart1UserControl.ascx(13): error CS0117: 'ASP._controltemplates_staffingwebparts_visualwebpart1_visualwebpart1usercontrol_ascx' does not contain a definition for 'ImportButton_Click' I need protected void ImportButton_Click(object sender, EventArgs e) somewhere but not sure where? using ( StreamReader reader = new StreamReader(NewResourceFileUpload.FileContent))

I'm sorry, I can't really help there, as I'm unfamiliar with ASP.NET. If I recall correctly, you took over this project from somebody else, right? I imagine there should be some code handling button-clicks in other parts of the application. Maybe you can take that as a kind of template how to do it. Else I would suggest you to open a new question in the ASP.NET forum so someone else can hopefully help you there.

Okay thanks. I going to submit what I have to my Director. They will just need to name the csv what I have in the code. I never got the hours to work.

[Norris Chappell]

Sascha, The Director is happy with code but would like to see the hours. I looped thru the code with debug and see that the #temptable is showing the hours but are not summing then. Would this select statement be where I need to focus? SELECT Tmp.Name, SUM(Tmp.Hours) FROM TempTable AS Tmp WHERE NOT EXISTS (SELECT * FROM StaffTracking AS ST WHERE Tmp.Name = ST.ResourceName) GROUP BY Tmp.Name;"; I have tried several different scenarios but no results. Thanks, Norris

[Sascha Lefevre]

Hi Norris, there's no # in front of "TempTable" there. If it's the same in your code, that might be the problem. If it's not that I have no further ideas because it works for me. I hope you'll be able to fix it - good luck! /Sascha

Ok. Thank you for your help.

[Norris Chappell]

Okay got it figure out for the Hours. I needed to add to sum(Tmp.Hours) as Hours. :) ;)

[Sascha Lefevre]

Cheers! :-D
