I'm trying to group almost-duplicate contacts in our database.
ie. ABC Corp, ABC Corp., ABC Corp.
The SOUNDEX function only returns a 4-character result. Many of our names are clearly NOT identical, yet return the same result.
Is there a better function I could use?

This depends what you are trying to achieve with soundex. If I remember correctly, soundex was created for immigration officers to search for potential names that sound the same, so it's not meant to be an exact match. The algorithm is very simple and you can extend it. However then it may not be as efficient anymore if used for original purpose.

Here's a sample output of name with Soundex. The name has spaces stripped out.
There are too many A345.
I looked up the algorithms, and will use D-M I guess.

That sounds fine.
Just a thought: If you're looking for quite exact matches, would it be easiest to create your own function and simply remove (for example using replace) all non-wanted characters like: '[space]%-.: etc. After that convert the string to lower case and using collations strip away accents and so on.

I'm already stripping punctuation and blanks.
Yes I think I have to write my own.
Even D-M only gives 6 digits, so it fails to differentiate my long strings.

Just a thought...
If you can afford to let this run as a batch update, maybe you can implement a Levenshtein distance algorithm and decide which records are dupes based on the distance.

I have created some packages which are using the same sharepoint file. So, when I try to run the jobs (having those packages independently) in parallel, I am not able to execute those. It shows an error stating that failed to acquire connection manager.
What I feel is that as the packages are sharing the same file, those are not able to share the files properly and so the packages are not able to connect to the file.
I just want to know if anyone of you know any changes that I need to make in the sharepoint file properties, in the package properties or in the job properties.
Thank you.

Hey guys
i need to create a new database using embedded fire bird, at the moment ive got this...
private void btnCreateDatabase_Click(object sender, EventArgs e)
{
if (FieldsValidated())
{
try
{
string fbConnectionString = string.Format("ServerType=1; Dialect=3; User={0}; Password={1}; Database={2};",
txtUserName.Text, txtPassword.Text, txtDbName.Text);
FbConnection.CreateDatabase(fbConnectionString);
DatabaseCreated(this, new CreateFirebirdDbEventArgs(fbConnectionString));
}
catch (FbException ex)
{
MessageBox.Show("btnCreateDatabase_Click - FbException" + Environment.NewLine + ex.ToString());
}
catch (Exception ex)
{
MessageBox.Show("btnCreateDatabase_Click - Exception" + Environment.NewLine + ex.ToString());
}
finally
{
this.Dispose();
}
}
}
... this creates the file just fine, but how do i create the tables in that db?
Thanks
<edit>
I came across a FbBatchExecution object which seems to do the trick

how to generate field number by increment (+1) in table mysql using PHP after inserting and deleting data?
ex:
Number
1A (next)
2A
3A

In SQL Server Management Studio (SSMS), in the Object Explorer, connect to your Database Engine, Databases, Expand your Database Name, Expand Tables, Right - click the Table Name in which you wish to have the increment number and select Modify from the context menu.
You will see the column names in that particular table.
Just select the column where you want the increment number and in the bottom in the Column Properties window, Expand Identity Specification. In the (Is Identity) from the drop down list select Yes and you will see the Identity Increment as 1 by default. That is what you need. If you wish you can change it also to 2 or some other number as you wish.
Hope this helps.
I was to descriptive to answer this simple question, but I am not sure how much do you know about it, so I thought of starting from the scratch.
Good Luck.

Are those "A"s part of the "number"?  If so, I don't think the system can do it automatically, you'd have to roll your own.

Hi all, i am building a category tree like structure for my FAQ app. i need to show all active categories. The hitch is that
if a parent category is checked as inactive, then the sub or child categories under it should not be displayed even if they
are marked as active. I need a query which will return me such a resultset which i can display in a table. the columns in my
table are categoryid, category, ParentcategoryID,companyID and active. The ParentcategoryID contains id of another category
or 'No parentcategory' which denotes its the main category. It is easy to get the immediate parentcategory and find out if
its active or not. But to find out if that parent category's parent and so on is active or not is tough. please help.

Dear All
in a multi threaded system, I want to access the sql server 2000 data base in 15 separate threads.
But now, when the connection of data base is lost , threads find it separately and they can not make other threads aware of this situation, also it is not possible to organize and manage the data base systematically.
now I want to manage my data base with better mechanisems.
I'd like to use design patterns for this purpose.
But I didn't find any useful information in this regard yet.
May you please let me know any information in this regard.
Thanks in advance

I'm no stranger to programming, but I am brand new to programming with databases. I use MS Visual C# 2005. I have tried making forms with datasets and table adapters and it looks just fine... that is, until I try to make a change.
I have a simple form with a single datagridview. I edit the records, click the Save button on the binding navigator, the tableadapter.Update() method returns the correct number of updated rows, but when I close the program and re-open it, the changes aren't there.
Am I leaving out something? Is there extra code needed? etc.?
Thanks.

I am able to pull the correct data in SQLDS1 for the dropdownlist. And, it seems as though SQLDS2 is pulling the correct data in the gridview. However, when selecting from the gridview to populate the detailsview, it only uses the rdb1aa field and i need it to be able to match the selected row data from rdb1aa and rdb2aa with two fields I am selecting from the JOIN in SQLDS3.
If anyone can help, I sure would appreciate it. My code is as follows:
