Can you post the relevant parts as plain text into this question?
Mika Wendelius at 5 days ago View
   
I can't go through all of your code so using debugger, locate the line where the error happens and what is the error message. This way you have information for a new question.
Mika Wendelius at 5 days ago View
   
I'd also suggest on trying to do a minimal test project with your code and see if it can be reproduced and post the test project.

I can't see your entire solution or what happens outside the method I wrote. So if the problem for this method is now solved, you can mark it as solved and open another question if you have problem somewhere else in the code. Just remember to post all relevant code parts with the question.
Mika Wendelius at 5 days ago View
   
I can't see that kind of line in the example I wrote. Are you using some other code?
Mika Wendelius at 5 days ago View
   
As far as I can see, that is the complete solution. Where do you get an error and what is the error you get?
Mika Wendelius at 5 days ago View
   
Sorry, forgot to change the return value type to decimal. The solution is now fixed.

In technical sense that is a valid statement so if adapt can appear in both fields title and author, then the query should be correct.
Mika Wendelius at 23-Feb-15 14:23pm View
   
You can download the VS 2008 SP 1 from here http://www.microsoft.com/en-us/download/details.aspx?id=13276[^]
Mika Wendelius at 23-Feb-15 14:19pm View
   
Not sure if I understood the logic but based on your code in the other question you have an AND in the where clause for both Title conditions. This would mean that the title should be adapt and adaxx at the same time but that's not possible.
 
So you probably should have a query like
SELECT *
FROM Books b
WHERE ( b.Title LIKE '%adapt%' or b.Title LIKE '%adaxx%')
AND Category = 'fiction'.
 
However if you use the full texts for the title you don't need like and you can use IN operator. Like this
SELECT *
FROM Books b
WHERE b.Title IN ('adapt', 'adaxx')
AND Category = 'fiction'.
 
Is this getting towards correct direction?

Thank you !
Mika Wendelius at 23-Feb-15 14:04pm View
   
Can you post a small example, based on the data in the question, what would your conditions be and what would you expect as a result?
Mika Wendelius at 23-Feb-15 13:52pm View
   
Agree, +5
Mika Wendelius at 23-Feb-15 13:34pm View
   
Your CASE statement inspects if the field category on a row contains a value 'fiction'. I wasn't sure what you wanted the result to be so I just added a constant literal 'found'. In other words for each row the select returns you get the text 'found' if the category is fiction. Is this something like you we're after or did you have something else in mind?
Mika Wendelius at 23-Feb-15 1:08am View
   
Why not test? Grab a Visual Studio and have a try. Using the debugger you can easily see what happens in each case.
Mika Wendelius at 23-Feb-15 0:17am View
   
Shape[] shapes = new Shape[3];
shapes[0] = new Shape(100, 100);
shapes[1] = new Square(200, 200);
shapes[2] = new Circle(300, 300);
 
If the array would be defined as Circle you wouldn't be able to add a Square into it.
Mika Wendelius at 22-Feb-15 23:44pm View
   
I agree, especially concerning down casting, however hopefully the OP gets a kick start from this.
Mika Wendelius at 22-Feb-15 23:27pm View
   
If it's not a store application, what is the exact error you're facing?
Mika Wendelius at 22-Feb-15 23:21pm View
   
I take it this is to concatenate all columns for a table and for all rows. Looks interesting.
 
I think you should have a cursor or something similar when looping through the table. Id's and row count do not necessarily match :)
Mika Wendelius at 22-Feb-15 23:15pm View
   
Solution updated for older versions.
Mika Wendelius at 22-Feb-15 14:04pm View
   
Glad it worked out

It seems that the code was just a diversion :)
 
Good links, 5.
Mika Wendelius at 22-Feb-15 11:15am View
   
Good options!
Mika Wendelius at 22-Feb-15 9:52am View
   
In that case have a look at Extending Visual Studio Setup Project[^]
Mika Wendelius at 22-Feb-15 9:42am View
   
What setup mechanism/program you use?
Mika Wendelius at 22-Feb-15 8:45am View
   
You're welcome :)
Mika Wendelius at 22-Feb-15 8:43am View
   
This is a far too big question to be answered in a single solution. Try to break down the problem, post a question concerning only one subject and state what you have already done.
Mika Wendelius at 22-Feb-15 8:40am View
   
Okay, I see. I truly believe that you shouldn't use this kind of design. Adding the columns daily is where your problem starts.
 
Instead of adding new columns, add new rows. So if you change the table to something like:
- roll_no
- attendance_date, date column
- present, 0 or 1
 
Then you can easily insert and query the data with a query like I wrote in the solution.
 
The main thing is that relational databases and SQL are designed to work with static structures. This is one of the reasons database normalization focuses on not repeating data and creating fixed entities.
Mika Wendelius at 22-Feb-15 8:25am View
   
I'm sorry but I don't quite understand. A table cannot have variable number of columns. The columns in a table are fixed.
 
Can you post few rows as an example data so it would be easier to understand the problem.
Mika Wendelius at 22-Feb-15 7:54am View
   
Few questions: What have you tried so far? Also can you post example data and the desired result
Mika Wendelius at 21-Feb-15 6:17am View
   
This really doesn't make any sense. I suggest that you try to eat the elephant in smaller pieces. Try to isolate the questions into single problems and then using google get more information about possible solutions and answers. At the moment it feels like we're just poking around...
Mika Wendelius at 21-Feb-15 6:14am View
   
Having another look, I think you're right.
Mika Wendelius at 21-Feb-15 6:06am View
   
Now this really feels like a homework and we don't do other people's homework. What have you done so far? Are you stuck in a specific question. If so, use the improve widget to add more information to your question and the code you have so far.
Mika Wendelius at 21-Feb-15 6:04am View
   
What is the problem you're facing, not able to do the selection based on another dropdown or what? What have you done so far?
Mika Wendelius at 21-Feb-15 6:02am View
   
That's true. However, since the OP wonders whether to C# or VB.NET I believe that familiarizing with ASP development wouldn't be a waste of time :)
Mika Wendelius at 21-Feb-15 5:53am View
   
Another thing is that you should pass the event as a parameter. So
onkeydown="ESCclose(event)"
 
Also instead of putting it on div, can you put it on body?
Mika Wendelius at 21-Feb-15 5:34am View
   
onkeypress isn't necessarily fired for Esc. Try onkeydown
Mika Wendelius at 21-Feb-15 5:28am View
   
If it throws an error when you put it in Excel, try your local separator. Mine is semicolon (;) but perhaps you have comma (,) or something else. So with comma the formula would be
 
=TRIM(LEFT(A1,FIND("-",A1)-1))
Mika Wendelius at 21-Feb-15 5:22am View
   
You're welcome :)
Mika Wendelius at 21-Feb-15 5:03am View
   
Do you actually call the function somewhere? For example in ONKEYDOWN event?
Mika Wendelius at 21-Feb-15 4:27am View
   
Good point.
Mika Wendelius at 21-Feb-15 4:04am View
   
If you have included the compact database in your Visual Studio project, you most likely write over the database file each time you start the application. Meaning:
- the database is included in your project
- you run the project everything is copied into the bin/debug folder
- you make modifications, they are stored in the db file in bin/debug
- you stop the application
- you start it again and again everything is copied into bin/debug
The solution is to place the database file to a location where you want to keep it and define in the project that it is not copied.
Mika Wendelius at 21-Feb-15 3:58am View
   
That's a lot of time.
I think the easiest way id to go back to the version you had in the beginning (separate statements and temp tables), create the permanent indexes, and the take the execution plan from the first query, post the query and the plan as a new question in Q&A and let's see what we can think of.
Mika Wendelius at 21-Feb-15 3:11am View
   
Exactly!
Mika Wendelius at 21-Feb-15 3:09am View
   
Where do you get the error, where does the debugger stop at?

That's just a code dump. Do yo have any specific problems or questions you can point out?
Mika Wendelius at 20-Feb-15 4:04am View
   
That's a big question. I suggest thta you narrow down the problem to smaller, specific questions you have in mind and open a new question in Q&A

Instead of calculating and storing the total by yourself I suggest using computed columns. See Specify Computed Columns in a Table[^]

This depends highly on the context. A reporting application getting data from a far remote database is quite different from low level I/O driver. What kind of situation you have?
Mika Wendelius at 19-Feb-15 12:45pm View
   
You should create the three first indexes in the database and let them be. Do not include them in your query. The indexes will live by themselves in the database. Typically indexes are created just once and never dropped.
 
An exception is the last index. It should be created after filling the temp table so:
 
...
insert into #ecampMatch(email_source, campaign, date_time, cell_id, filename)
select distinct email_source, campaign, date_time, cell_id, filename
from master
where campaign in (select distinct campaign from ReportingAcxiom);

CREATE INDEX ecampMatch_campaign ON #ecampMatch (campaign, email_source, cell_id);
...

Do you mean a total row or a total column?

Mika Wendelius at 19-Feb-15 10:21am View
   
You can't see the new row in the database? If not, how did you verify it?
Mika Wendelius at 19-Feb-15 9:45am View
   
What do you mean by another process? Consider the following
if (cbProductDescription.SelectedItem.ToString() == "Prepaid - 300")
{
command.Parameters.AddWithValue("@Price", 7);
}
else
{
command.Parameters.AddWithValue("@Price", DBNull.Value);
}
Mika Wendelius at 19-Feb-15 9:36am View
   
Yes, I can see that based on your data. Again what is the actual table structure? Without knowing the table structure it's impossible to help you to write the statement.
Mika Wendelius at 19-Feb-15 9:04am View
   
As PIEBALDConsult pointed out the records are in no actual order. Is this really the structure of the database? can you post the Table definition, what columns it contains, what data types etc.
Mika Wendelius at 19-Feb-15 7:20am View
   
Yes, for example have a look at PHP Connect to MySQL[^]

If it's a DLL you have made, why do you need to make changes into the DLL rather than change the source code?
Mika Wendelius at 19-Feb-15 2:30am View
   
If you don't have a value then I take it that in your scenario you should set the column as NULL in the database. In order to do that, define the value of the parameter to DBNull.Value[^]
Mika Wendelius at 19-Feb-15 2:14am View
   
I don't think that would work correctly. Based on the selection in the combo box you should define a value for both Price and Total in both cases. Otherwise you have a parameter in a query text but you don't provide any value to it.
Mika Wendelius at 19-Feb-15 1:03am View
   
If you want to use the data from another datatable as a filter, concatenate the value to the filter property. Like
 
dv.RowFilter="country_id = " + dr["country_id"].ToString();
 
I didn't quite understand how the stored procedure is related to this...
Mika Wendelius at 19-Feb-15 0:35am View
   
The length of the query is not likely the reason. What is the full error you get?
 
Also using debugger, copy the statement that is going to be executed in your code to the clipboard and try to run that in MySql. Does it run? This way you can ensure that the statement is exactly the same in both cases.
Mika Wendelius at 19-Feb-15 0:33am View
   
Please post the relevant part of the code you have made
Mika Wendelius at 19-Feb-15 0:23am View
   
Pictures method expects to get a number (index). If you pass a string or improper index number, then an error is generated.

You're welcome :)
Mika Wendelius at 18-Feb-15 3:38am View
   
The length of the name of the column doesn't restrict the amount of data that can be stored into the column. It's just a name.
 
Can you post the code you're currently using?
Mika Wendelius at 18-Feb-15 1:09am View
   
So far you have just defined the requirement. What have you done, where are you stuck at?
Mika Wendelius at 18-Feb-15 0:33am View
   
Sorry but I don't quite understand the question. If the statement fails you will get an error message. The data shouldn't be truncated unless you manipulate it in some way.
Mika Wendelius at 17-Feb-15 1:40am View
   
It sounds like auto complete may not be the right solution in this case. If the amount of the data rows is so big that it takes too much time to fetch it, how would a user be able to select from the list?
 
Perhaps you should consider some mechanism to narrow the possibilities, peharps some more input from the user...
Mika Wendelius at 16-Feb-15 23:43pm View
   
That's true that the user needs to know few characters, but why would you fetch the data from the database each time? Just store it on the client side, for example in a datatable and select appropriate portion each time you need one. Having a database call in this kind of situation would be a performance killer.
Mika Wendelius at 16-Feb-15 4:44am View
   
That is why I used the COALESCE. It returns the first non null value :)

Mika Wendelius at 15-Feb-15 5:35am View
   
In that case you need to build a small program. You can use PL/SQL to do it or some other language that can connect to the database.

Nice answer!
Mika Wendelius at 13-Feb-15 13:21pm View
   
You're still doing it wrong. The only correct way is to use parameters. Otherwise you're not able to control what the statement will be. For example if your password is ABC'DEF you will get a syntax error for the statement.
 
Try correcting the code to use the parameters this way we can concentrate on the actual problem if it still exists.
Mika Wendelius at 13-Feb-15 9:46am View
   
No, concatenating strings to SQL statements is evil. And when the data comes from a text box or similar it's even worse. Parameters is the correct way to go.

What normalization do you mean? Quantile normalization, normalizing frequenxy for digital signals, database normalization or something else.
 
Also please explain what exact questions you have in mind? I'm asking these since currently the question is far too vague to be answered with anything more than few links...
Mika Wendelius at 12-Feb-15 15:39pm View
   
It really depends. Service based database must be installed separately and it can be multi user. Embedded database can be entirely embedded into your application but it's single user only.

One thing you could check is that does the program have both read and write access to the folder where the accdb file is and make sure that the file isn't read only.

Are you sure that you don't have a foreign key from Category to Skill? The error message implies that the foreign key is referencing to the Skill -table?

You can reply directly to the answer. I'll update it shortly.

What error do you get?
Mika Wendelius at 23-Jan-15 10:04am View
   
Good catch thanks :) Fixed now.

As far as I can see this is a portable solution as long as you also send the rdp file. The rdp file is actually a simple text file. You can use notepad to open it and see the content.

Can you give an example source data

Please don't repost. You already asked this question here: How to move the data from one ndf to another ndf file . . . . . .[^]

If updating statistics fixed the situation and it occurred again you may be facing a plan stability problem. This means that the database engine cannot decide a good plan and and it changes. Usually these kinds of problems can be solved by changing indexes, simplifying statement or using hints.
 
However, have you made sure that it's not a workload problem. Meaning that when this happens, the server is under heavy stress? Use Windows performance monitor to see the CPU load and if the server is swapping

I see, if you have Visual Studio, perhaps you could use https://msdn.microsoft.com/en-us/library/dd172133(v=vs.100).aspx[^]
 
Then there aro a lot of 3rd party tools like http://www.ubitsoft.com/products/sqlenlight/[^] or http://www.devart.com/dbforge/sql/studio/sql-analyzer.html[^]

Without going through all your code it's quite impossible to say if that code excerpt fine or not. I suggest going thruogh the code using debugger and to see what are the values you're trying to add to the tables and in which order.
Mika Wendelius at 22-Jan-15 3:49am View
   
It looks like you're trying to use Named pipes protocol from the client side. By default that protocol isn't enabled. I suggest that you use TCP/IP but if you want, you can enable Named Pipes on the server side using Sql Server configuration tool

With default instance you don't specify a name. Did you try copying the connection string from SSMS?
Mika Wendelius at 22-Jan-15 0:56am View
   
NO, you never share the database files or other file resources from the DB server. TP is enough taken that:
- server listens in default port (1433)
- you don't have named instances
 
If you have named instances or another port, those should be defined in the connection string.
 
Try to establish the connection on the server using for example SSMS and when succesfull copy the connection string from SSMS properties window.

From the technical point of view yes, but the correctness of the expression is defined by the need. In other words, it depends on what you need to fetch :)
Mika Wendelius at 21-Jan-15 23:11pm View
   
Have a look at this, it should help you to find the correct window https://msdn.microsoft.com/en-us/library/ms175518.aspx[^]

The problem with your question is that you haven't proven that you have put some effort into it. If you post what you have tried so far and where you got stuck I believe you'll get good answer. However, if you let the question be as-is, people interpret it so that you're trying to get them to do your homework.
 
So the key thing is to show that you have really done something and to clearly point out what is hard to figure out. After all the whole point of your assignment is that you learn how to do such things. In other words learning is an investment to yourself :)
Mika Wendelius at 21-Jan-15 13:21pm View
   
Done, next please :)
Mika Wendelius at 21-Jan-15 8:39am View
   
Why do you say it's not working? Can you post the code you have tried.
 
In overall, I really don't suggest that you use the approach presented in solution 2. In my opinion you should rely on tested mechanisms that are built in in the framework instead of coding an alternative.

Removed username and password from the connection string
Mika Wendelius at 20-Jan-15 0:55am View
   
You're welcome :)
Mika Wendelius at 20-Jan-15 0:25am View
   
Do you get an error message or have some other kind of problem?
Mika Wendelius at 19-Jan-15 3:52am View
   
Of course the client side also affects. Why not test with another client computer. Also double check the connection string and the instance name.
Mika Wendelius at 19-Jan-15 1:17am View
   
Glad it helped :)
Mika Wendelius at 18-Jan-15 9:47am View
   
Yep, indexing. Proper indexing is the key to fast access. Also you have to consider limiting the time frame. Do you always calculate all the starts and stops from all time beginning or for example only for last week or so.
Mika Wendelius at 18-Jan-15 9:45am View
   
In that case I guess the best option is to define what is the maximum amount of columns to be generated (in your example it was 4) and then select the items (Ball, Apple, Dog etc) based on their alphabetical order...

Do you mean you need to store the equation as text in the database but the text must support special characters?

The exception is in the innermost StackFrame. This is where the code stopped. You can easily verify this with the debugger. Just place a breakpoint to the exceptioin handler and see what each frame actually contains.
Mika Wendelius at 17-Jan-15 10:11am View
   
The frames describe the part of the program which is executed at the moment. Each call to another method adds a new frame to the stack. For example
- Your main loop is calling Method1 => new StackFrame added
- Method 1 is calling Method2 => new StackFrame added
At this point you would have two frames describing the point where the program is executing for each method.

That doesn't sound legitimate and is against the terms of use. I see no reason why you should try that.

ddl_value2 is not an input parameter for the procedure. Have a look at your declaration:
 
ALTER proc sp_insert@test1
(
@Value2 varchar(50), ...
 
The names of the variables must match throughout the scope.

The network service may not have access to the specified network share. Instead of using built-in accounts try specifying a domain account which has privileges to connect to the share and also privileges to be run as a service.
 
From MSDN: "NetworkService account has minimum privileges on the local computer and acts as the computer on the network.". See NetworkService Account[^]
