Searching A Column For A Value To Avoid Inserting A Duplicate Value
Jul 17, 2007Hi there, newbie here.
I'm building a web application that allows for tagging of items, using ASP.NET 2.0, C# and SQL Server.
I have my USERS, ITEMS and TAGS separated out into three tables, with an intersection table to connect them.
Imagine a user has found an item they are interested in and is about to tag it. They type their tag into a textbox and hit Enter.
Here's what I want to do:
I want to search the TagText column in my TAGS table, to see if the chosen tag is already in the table. If it is, the existing entry will be used in the new relationship the user is creating. Thus I avoid inserting a duplicate value in this column and save space. If the value is not already in the column, a new entry will be created.
Here's where I'm up to:
I can type a tag into a textbox and then feed it to a query, which returns any matches to a GridView control.
Now I'm stuck... I imagine I have to use "if else" scenario, but I'm unsure of the code I'll have to use. I also think that maybe ADO.NET could help me here, but I have not yet delved into this. Can anyone give me a few pointers to help me along?
Cheers!

Need To Avoid Repeated Data In A DataGrid
Apr 15, 2004Hi there :)
I am developing a system for my uni course and I am stuck a little problem...
Basically its all about lecturers, students modules etc - A student has many modules, a module has manu students, a lecturer has many modules and a module has many lecturers.
I am trying to get a list of lecturers that run modules associated with a particular student. I am able to get a list of the appropriate lecturers, but some lecturers are repeated because they teach more than one module that the student is associated with.
How can I stop the repeats?
Heres my sql select code in my cs file:
string sqlDisplayLec = "SELECT * FROM student_module sm, lecturer_module lm, users u WHERE sm.user_id=" + myUserid + "" + " AND lm.module_id = sm.module_id " + " AND u.user_id = lm.user_id ";
SqlCommand sqlc2 = new SqlCommand(sqlDisplayLec,sqlConnection);
sqlConnection.Open();
lecturersDG.DataSource = sqlc2.ExecuteReader(CommandBehavior.CloseConnection);
lecturersDG.DataBind();
And here is a pic of my Data Model:

Any ideas? Many thanks :) !
How Can Avoid Displaying Data Using A Cursor ??
Oct 16, 1998I defined a stored procedure with a cursor inside for updating data.
When I call it from an MSAccess client, it fails.
When I execute it directly in a ISQL/w windows, it doesn`t fail but it displays me the data (wich is the reason for failing from MSAccess).
Do somebody know if I could do it without displaying data in the screen ??
Massive Data Import, How To Avoid Dublicates?
Dec 4, 2006Hello,
I am currently working on a project where I have to import a huge amount of data from CSV files into a database.
I don't want to have dublicate keys in my table, but my CSV file contains them. That means the line more at the end of the file contains the mor up to date information that I have to store.
I try to fix this problem since serveral weeks, but my algorithm is very slow and blocks all other processes on the server. At the moment I am copying all records into a temp table that occure more than once in the CSV file. After that I am running through this table line by line and check if the key already exists in the target table and then either make an insert or an update.
Does somebody know a better process?
I hope somebody can help me... :(
Avoid Cross Database Views In Data Warehouse
May 4, 2007We have a relational database (rd) and a data warehouse (dw). This dw has a table (tw) with all key fields (dimension keys) and metric related (measures) fields. This table is populated with monthly data each month. The tw is joined to various look up views present in the dw to obtain name fields from rd. The DBA wants me to remove the look up views. I now have following 2 options that I can think of –
1)Further de-normalize the tw and store the name fields as well. However, there are two issues with this option –
a.The size of tw will grow tremendously.
b.We are storing monthly data and the values in the name fields may change after some time. Then we will have to put in additional views/objects to obtain the latest name.
2)Using ETL, obtain the copy of rd tables overnight in dw. We will then join tw with these tables and there will no longer be cross database joins. However, this will be a burden on maintenance and support.
As of now these are the possible options I can come up with. Which one would you suggest and why? If you have another option, please let me know.
Thank you all in advance,

How Can We Avoid Somebody To Access The MDF Data By Doing User Instance Connection?
Dec 11, 2006I created a database that will be distributed to my customers. This database is running on an Instance of SQL Server 2005 Express edition. I removed the admin logins from my SQL Server Instance so in theory, only my application connecting itself using the Sql Server autenthication will be able to be access the data (using "sa" having a password that I set at the installation).
For now, all this is working fine and after some tests, I haven't been able to access the data in any ways except by using the "sa" and the password my app is the only one to know.
But the problem is coming from a security leak when using User Instance. Indeed, I've been able to create a program getting the content from my MDF file. If somebody try to get connected using User Instance on his own SQL Server instance, he will be able to reach the data.
How could I prevent this to happend? Is there a property or something that could be set into the database that would prevent the database (mdf file) to be used with User Instance?
Thanks!
DB Engine :: How To Avoid Special Characters While Migrating Data
Jun 23, 2015I have a source sql 2005 with the database collation SQL_Latin1_General_CP1_CI_AS and destination with sql 2012 with the same collation.
But the SQL server llvel collation is different, sql 2005 uses Latin1_General_CI_AI and sql 2012 uses "SQL_Latin1_General_CP1_CI_AS"
Now when i load the data from 2005 for one table to sql 2012 i could see special characters in one column. And i dont see that in the source database. Is there a way to avoid that or is it something we need to manually fix.

Delete Rows With Duplicate Column Data But Unique Row Data
May 25, 2000Hello,
This probably has been addressed before but I was unable to get the search to work properly on this site.
I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example :
Row 1
Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Row 2
Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc.
Row3
Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc.
Row 4
Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Etc. Etc.
I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.
I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,
Kerry

Duplicate Data?
Nov 17, 1998I am new to SQL server 6.5.
I will need to stress test a sql server 6.5 test database by duplicating
data. To do so, I need to know how to modify the primary key(which are
numbers in character data type) to duplicate the data several times over.
The primary key is character data.
What I have done ion the past is use insert statments -let's say 20 -- and then copy them and change the date in a text editor and change the primary key column and the other coluimns with thea replace of different letters and numbers. This is slow and tedious.
Does any one have a script I can run to do so?
Can I do this sql or do I need some sort of stored procedure? Any help
would be appreciated. Thanks.

Duplicate Data
Aug 28, 2007Hello all,
I have recently been working on a project that requires one simple table to insert data into. The problem here is that all the data inserted must only access the database via stored procedure and I want to ensure that no duplicate data is inserted in the database.
I have done quite a bit of research for many ways to perform duplicate data testing from building temp tables and on, but nothing has really stood out to me yet. I would really like to find some information on how to perform duplicate data testing using a stored procedure that allows to test the data being inserted before it is saved to the database; therefore, when the user inserts the fields and clicks the insert button, the fields will be tested against the existing data (via stored procedure) within the database before being added.
Can anyone help?
Thanks

Inner Join Duplicate Data
Jun 13, 2000i have 2 tables not connected in any way
but both have orderid filed (same filed).
In one table this filed (and onther one) are keys,
the second table dose not hace a key at all.
The same order_id CAN repeat itself in each table.
When i try to join the tables (some rows just in one table and some in both):
Select tab1.name, tab1.orderid, tab2.sku
from tab1 inner join tab2 on tab1.orderid=tab2.orderid
The result i get is duplicate.
each row is multiple.
What I'm doing wrong?

Remove Duplicate Data
Dec 16, 2004I have a query that for one reason or another produces duplicate information in the result set. I have tried using DISTINCT and GROUP BY to remove the duplicates but because of the nature of the data I cannot get this to work, here is an example fo the data I am working with
ID Name Add1 Add2
1 Matt 16 Nowhere St Glasgow
1 Matt 16 Nowhere St Glasgow, Scotland
2 Jim 23 Blue St G65 TX
3 Bill 45 Red St
3 Bill 45 red St London
The problem is that a user can have one or more addresses!! I would like to be able to remove the duplicates by keeping the first duplicate ID that appears and getting rid of the second one. Any ideas?
Cheers

Displaying Duplicate Data
Jun 15, 2007Hi. Not sure which section this request needs to be put in, but i'm relatively new to SQL.
I have 1 table which contains an user_id (autonumber), user_name, and user_profile.
I have 2 other tables:
config_version (cv) and config (c)
These two tables both access the user table (us) to view the user_id (which is required).
I want to be able to view the user_names for both "cv" and "c" on a seperate page. Using the code below, i'm lost. I created what i wanted in MS Access with the use of a 2nd table (this might be easier to understand than my rant above). However, I don't want a 2nd table.
Can someone provide me with a function, or the "answer" to my problem?
Highlighted Blue - just there to fill in the front page with data (not wanted)
Highlighted Green - doesn't work, but was my first attempt

Set objConn = Server.CreateObject("ADODB.Connection")
objConn.ConnectionString = strConn
objConn.Open
Set objADORS = CreateObject("ADODB.RecordSet")

Some ofthe existing smaller DBs already have most of the data for theirrespective years. But some of the same data is also on the source DB.If I simply do an insert keying on the year column, and a row beinginserted from the source DB already exists in the target DB, will aduplicate row be created?And if so, how can I avoid that?Thanks,John Steen*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

I have a dataset which I would like to remove data from, but I can't seem to find out how to do this.
The dataset contains the following columns:

I am new to SSIS and can't see how I could do this (although I'm sure it's possible).
If anyone could show me how I would appreciate it.

CREATE TABLE DUPLICATE OBJECT/DUPLICATE FIELD NAME ERROR Msg 2714
Oct 2, 2007Hello Everyone:
I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.
When I try to create the tables, for the query, I am getting the following error:
Msg 2714, Level 16, State 4, Line 12
There is already an object named 'UserID' in the database.
Msg 1750, Level 16, State 0, Line 12
Could not create constraint. See previous errors.
I have duplicated this error with the following script:
USE [testing]
IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users1]
CREATE TABLE [testing].[dbo].[users1] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users2]
CREATE TABLE [testing].[dbo].[users2] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users3]
CREATE TABLE [testing].[dbo].[users3] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.
I think that the schema is only allowing a single UserID primary key.
How do I fix this?

How Can I Prevent From Inserting Duplicate Data?
Dec 31, 2006
I have a table storing only 2 FKs, let's say PID, MID
Is there any way that I can check distinct data before row is added to this table?
For example, current data is
PID MID------------100 2001100 2005101 3002102 1009102 7523102 2449
If my query is about to insert PID 100, MID 2001, since it's existing data, i don't want to add it. Can I use trigger to solve this issue?
Thanks.
