Im looking for a sql solution for counting records in a bridge table. I want to select all in table1 and add a column with count of each author's titles. Ive tried
SELCET Table1(*), COUNT(DISTINCT table.au_id) AS Titles
but keep getting an error.
The tables I have are as follows:
Table1(
au_id
au_fname
au_lname
ect..)
Table2(
au_id
title_id)
Table3(
title_id
title_name)
I tried so much working with this to get distinct Words and their count. I'm using ASP.NET 2.0. And i also googled so much.
1)Ex(String): The DOTNET is Very Cool! The Best.
2) Capture all the sequences like Space, FullStop, Question Mark, Exclamation, Apostrophe, New Line....(May be with RegEx?)
3)Split Words According to the above sequences
4)Get Distinct Words(Occurences) and their count based on the input string in 1st statement.
Desired O/P:
The - 2
DOTNET - 1
Is - 1
Very - 1
Cool - 1
Best - 1

I have a list of ids properly stored in a List<>. I now need to Group list and get a count of the number of occurrences sorted descending.
Example:
List<string> aryIDs = new List<string>;
aryIDs.Add("1234");
aryIDs.Add("4321");
aryIDs.Add("3214");
aryIDs.Add("1234");
aryIDs.Add("4321");
aryIDs.Add("1234");
Would Produce:
"1234", 3
"4321", 2
"3214", 1
This would be easy in TSQL, but I would like to avoid the server roundtrip, unnecessary tables, etc. if possible.

I have a data table called Songs It has SongId as Primary Key of type INT SongName of Type VarChar UserId of Type Int. I simply want to check how many entries are in the Table already by The UserId before they insert more. So If there are already 3 songs by that User, I want to stop the insert process and warn them they have the maxium already. I think i am halfway there already using code below but problem is that UserId is of Type GUID, and not Int so I am missing something. On my Aspx, Page, I have a DetailsView for the Database Insert. I also have the following code using BusLogic Layer and DAL
SongsBLL
public int ScalarQuery(Guid ArtistId)
{
int returnValue = ScalarQuery(ArtistId);
return returnValue;
}
Code Behind ASPX page
This in in DetailsView_ Item Inserting Event
SongsBLL number = new SongsBLL();
currentCount = Convert.ToInt32(number.ScalarQuery(currentCount).ToString());..........
I have 2 table's
Table 1: Daily_item

New table example:
Table 2

I am fairly new to C# programming and I am stuck on my little ASP.NET project.
My website currently examines Twitter statuses for URLs and then adds those URLs to an array, all via a regular expression pattern matching procedure. Clearly more than one person will update a with a specific URL so I do not want to list duplicates, and I want to count the number of times a particular URL is mentioned in, say, 100 tweets.
Now I have a List<String> which I can sort so that all duplicate URLs are next to each other. I was under the impression that I could compare list[i] with list[i+1] and if they match, for a counter to be added to (count++), and if they don't match, then for the URL and the count value to be added to a new array, assuming that this is the end of the duplicates.
This would remove duplicates and give me a count of the number of occurrences for each URL. At the moment, what I have is not working, and I do not know why (like I say, I am not very experienced with it all).
With the code below, assume that a JSON feed has been searched for using a keyword into srchResponse.results. The results with URLs in them get added to sList, a string List type, which contains only the URLs, not the message as a whole.
I want to put one of each URL (no duplicates), a count integer (to string) for the number of occurrences of a URL, and the username, message, and user image URL all into my jagged array called 'urls[100][]'. I have made the array 100 rows long to make sure everything can fit but generally, this is too big. Each 'row' will have 5 elements in them.
The debugger gets stuck on the line: if (sList[i] == sList[i + 1]) which is the crux of my idea, so clearly the logic is not working.
Here is sample code:
var sList = new ArrayList();
string[][] urls = new string[100][];
int ctr = 0;
int j = 1;
foreach (Result res in srchResponse.results)
{
string content = res.text;
string pattern = @"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\))+[wd:#@%/;$()~_?+-=\.&]*)";
MatchCollection matches = Regex.Matches(content, pattern);
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
sList.Add(groups[0].Value.ToString());
}
}
sList.Sort();
foreach (Result res in srchResponse.results)
{
for (int i = 0; i < 100; i++)
{
if (sList[i] == sList[i + 1])
{
j++;
}
else
{
urls[ctr][0] = sList[i].ToString();
urls[ctr][1] = j.ToString();
urls[ctr][2] = res.text;
urls[ctr][3] = res.from_user;
urls[ctr][4] = res.profile_image_url;
ctr++;
j = 1;
}
}
}
The code then goes on to add each result into a StringBuilder method with the HTML.Is now edite

my main intention is that, the exsisting table of sql server database(.dbo) with 1000's of records, that should be import to a new access database table(.mdb).for example if we want to had a new table in db2, of exsisting table in db1 with some conditions by using "select * into New_Tabel from (select * from Exsisting_Table where <Condition>) as objectName". Here the new table is created and records inserted in one execution in db2. The same work should be done for access(sqlserver db --> Access db).Here the new access database table with given name (as string_sysdate) must be created dynamically by clicking a button (multiples time creating new table).Is there any query or c# code for sql server database to access database.
