>>>Check duplicate while inserting record from Texbox.

  
Hi, On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value. Then if user will provide some other telephone number then he allows to insert record. For insertion of record I used ObjectdataSource. User will enter telephone number in a simple textbox. I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit. Any idea would be appreciated.

Hello, I need some major help. I have a query (see below) that returns survey results... For some reason, some surveys get submitted multiple times.

Formview check for duplicate value before insert

  
I've looked at some posts on here but I keep getting errors.  I am just trying to see if an email address exists already before the insert and if it does, have a label display that message to the user. From what I read so far, it looks like I could do a query in the ItemInserting event.  I just need help on the code.  Thanks in advance for any help..

My student code procedure

Filtering duplicate records - spelling mistakes, order of wordings in phrase

  
Hi friends,

 I have a table with thousands of records which I get from a flat source file.
 I need to filter this data and remove duplicate records. I read about SSIS fuzzy logic and grouping and  all that.
But I need a simpler way as I have only one table without any relation or highly complex structure.

for e.g. two records with city name 'Bunnell' and 'Bunnel' or 'Fernandia beach' and 'Fernandia bch' should be considered as same.

Any help or suggestion is appreciated very much.

Fuzzy lookup problem...same/duplicate records in the buffer,

  

Hi there,

I have a problem with a fuzzy lookup and I've been checking all the forums and not only that I can't find the answer but I can't even find other people having this issue although it seems to me that this would happen quite often to people using fuzzy lookup or even the regular lookup component. Here's the problem:

Lets say I have 10,000 records in the source database and I have 500 records (not really important) in the reference table that I'm using for the fuzzy lookup. Lets also say that the buffer size is 1000 records. Here's what happens, the first buffer will check if any of the first 1000 records (out of 10,000) is the same (or similar) to any of the records in the reference table and then based on the similarity value that I've set up (say .80) it'll either take a route "Existing" (if the same or is similar record exists in the reference table) or take the route "NonExisting" (if the incoming records is different than any of the existing records in the reference table or if the similarity value is below .80). The idea here is that if the records goes to "Existing" this record (which is a person btw) will be assigned the same PersonId as the same/similar person found in the reference table. If on the other hand record (person) ends up going to "NonExisting" it'll be assigne

Need help getting rid of Duplicate Records

  

Hello;

I’m pulling data out of a MySQL Database (Bugzilla data) to be later merged with data that lives in a SQL Server data Mart. The problem I’m having is in the way Bugzilla handles State transitions. It timestamps everything and adds it into an activity table so you get a record of everything that happened to the Problem Report – That kind of makes sense for audit purposes.

The problem I’m having is that I only want to get the last updated value and not the previous ones or else my Pivot Transform will fail with a duplicate entry error.

Does anyone know how I can select only one of the many entries - Either a Transform or changes to my query? Below is an example of my data, the Bolded Underlined rows are the ones I want to keep, the others are to be discarded.

Any help will be extremely appreciated.
