Check For Duplicate Entries In One Field
Oct 17, 2005Obviously, I'm a complete n00b at SQL.
I have a table in Access 2003 with about 6,000 records and there are about 20 records that have duplicate data in the first field (CompID).
I'm trying to make the first field my primary key, so I need to fix these duplicate entry.
I could export to Excel and fix the problem that way, but in the interest of learning SQL I want to figure out how to do it properly.
Thanks in advance for what is hopefully a simple answer.
No Further Entries Of A Value In Table
Mar 30, 2012I have a table which stores phone numbers of a customer in a table.
Say this table is as below
CustomerName - PhoneNumber
Customer 1 - Phone number 1
Customer 2 - Phone number 2
Customer 2 - Phone number 3
Customer 3 - Phone number 4
What would be the best approach to prevent adding another entry against Customer 2. I should be able to add new customers and add multiple phone number against all other Customers. The restriction should be only against Customer 2.

How To Know The Order Of Entries In A Table
Jul 5, 2007For example some data has entered into a table in a random manner i.e the pk filed value is not in a serial fashion.Is there any table or index that holds the entries of rows into a particular table as entered .
i.e
'some_table' has data like this
3,entry3
2,entry2
4,entry4
1,entry1
I want some DB table or Index that holds data like this about above 'some_table'
row_id .... .... ....
1

3
4
here 1 refers to entry of the first column in 'some_table' i.e 3,entry3
and so on...

Save DELETED Entries To New Table
Mar 23, 2008Hi all
I would like to know if its possible to "Save" records when they get deleted.
For example: I have a table, tblUsers, with coulmns, UserID, Name, Surname, etc...
In VWD I've created a GridView which shows everything on a webpage. I've also added a confirm return('Are you sure you want to delete the user?') option in OnClientClick field. What i want to achieve is, have some sort of log file, or log table if you want to call it that, of which users has been deleted by the end user. So, in later stages, i can see who deleted who, when, where, etc... - by building a report or view.
All this should go to a seperate database or seperate table, it doesnt really matter.
My delete query:DELETE FROM [tblUsers] WHERE [UserID] = @UserID
Prevent Duplicate Entries In A Table
Nov 11, 2003I have an ASP.Net Web appplication with a Back-End SQL DB. There are 3 Tables; Users, Groups, and GroupMember.
The GroupMember table is used to link Users to Groups and consists of just two fields; userID and GroupID.
Here is a sample of some data:
User1 Group1
User1 Group2
User2 Group2
User3 Group1
User3 Group3
Users can belong to multiple Groups. However, you shouldn't be able to have the same user and group comobination more than once. for example:
User1 Group1
User2 Group2
User1 Group1
I can stop this kind of duplicate data entry by doing a lookup first (using asp.net) to see if the entry already exists but this seems cumbersome.
Is there a simpler way to prevent duplicate entries in a table using sql?
Thanks a lot,
Chris
Appending And Deleting Entries In Table
Jul 11, 2014I have a question on appending and deleting entries in mysql table. This is my sample table.
table name: details
id_name | model | mode | media| first | end | id | level |
+--------------------+-------+---------+-----+-------+-------+--------+--------+
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14684 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14838 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15236 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |
| PSK_30s1207681L002 | 1 | 1 | N | 14026 | 15627 | 6255 | q |
[Code] ....
I have numerous entries of same id name belonging to same median number.However,I want to only retain the entries having the longest first and end position and discard the remaining entries
E.g. for id name ="PSK_30s1207681L002" AND median = 5 we have four entries
id_name | model | mode | media| first | end | id | level |
+--------------------+-------+---------+-----+-------+-------+--------+--------+
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14684 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 14838 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15236 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |
| PSK_30s1207681L002 | 1 | 1 | N | 14026 | 15627 | 6255 | q |
But I want to retain only the one having longest first and end points ie
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |
| PSK_30s1207681L002 | 1 | 1 | N | 14026 | 15627 | 6255 | q |
Here ,since for id name ="PSK_30s1207681L002" & median = N we have only 1 entry I want retain that one.
My final output in mysql table should look like this.
id_name | model | mode | media| first | last | id | level |
| PSK_30s1207681L002 | -1 | 1 | 5 | 14026 | 15423 | 6255 | q |
| PSK_30s1207681L002 | 1 | 1 | N | 14026 | 15627 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | 3 | 14033 | 15627 | 6255 | q |
| PSK_30s1207681L002 | -1 | 1 | T0 | 15550 | 16050 | 6255 | q |
| PSK_30s1189731L001 | -1 | 1 | 3 | 999 | 7531 | 9808 | c |
| PSK_30s1189731L001 | -1 | 1 | 5 | 6609 | 8257 | 9808 | c |

Searching For Entries In Subsequent Log Entries?
Dec 2, 2013If I wanted to search for Jobs as a particular status (e.g. 0130) and wanted to keep the jobs at this status until it has reached 0500, 0125, or 0900 in it's subsequent status log entry, how can I write the SQL for it to achieve it?
I have the following SQL which searches for the Jobs at 0130, but don't know how to develop it further to search on the requirement above.

Jul 20, 2005I have a table 'Group2Operation' that stores many to many relationsbetween the 'Group' table and the 'Operation' table (each group is haspermission to perform one or more of the available operations)PROBLEM=======I need to prevent duplicate entries being created. e.g. lets say thatin the 'Group2Operation' table a record links the 'editor' group tothe 'publish' operation. Should I prevent an administrator creating aduplicate of that record? (Otherwise deleting that permission willhave to be done twice or more for it to be effective)SOLUTION?=========So far I've done this with a trigger:CREATE TRIGGER Group2OperationDuplicates ON dbo.Group2OperationFOR INSERT, UPDATEAS UPDATE Group2OperationSET NoDuplicate = CONVERT(nvarchar(10),GroupID) + OperationTagThe 'NoDuplicate' unique index column in the Group2Operation tablestores a concatenation of the unique group and operation identifiers.So when an attempt is made to create a record, the trigger is fired.If there is a duplicate, this will mean a duplicate entry in the'NoDuplicate' column. As a result, the INSERT or UPDATE will fail andthe duplication will be prevented.WHAT DO YOU THINK?==================What do you think? Am I going about this in the right way? Is atrigger a good way to do this or should I rely on application logic toprevent duplicates?Any help appreciated by this db novice.John Grist

Writting Trigger Or Procedure To Delete Duplicate Entries In A Table?
Sep 3, 2007I am using Sql Server 2000.
I have a customer table with fields - CustId, Name, Address, City, StdCode, Phone.
I used to insert entries in this table from an excel file.
One excel file will contain thousands of customer.
In this table combination of StdCode and Phone should not be repeated.
If I do it in my VB.Net coding.then application gets drastically slow.
So I want to write a procedure or trigger for this.
Here what I will do, I will send all records into database then this trigger or procedure will check for
any existing entry of combination of StdCode and phone. If entry exists then this will delete new entry
or will not allow this new entry.
Is this possible to do using Trigger or stored procedure?

Jul 9, 2004Hi...
Is there any way to check previous row in SQL Query?
I have a table with these column :
Name1
Name2
Audit_Time (datetime)
Changes
I want to delete record from database in which the Audit_time is <'01/05/2004'.
However before deletion, I want to check, if the Changes value is 'OLD' And the previous value is 'NEW', I will check the Audit_time of the NEW instead of OLD.
Table :
Row Name1 Name2 Audit_Time(mm/dd/yyyy) Changes
1 ABCD EFGH '01/01/2004' ADD
2 ABCD EFGHIJ '01/04/2004' NEW
3 ABCD EFGH '01/04/2004' OLD
4 Klarinda Rahmat '02/08/2004' NEW
5 Klarinda Rahmat '01/04/2004' OLD
In this case, I want to delete row 1,2,3 Where the audit_time are < '01/05/2004'.
Row 5 the audit_time also < '01/05/2004', however the changes='OLD' and the previous value changes='NEW', so I will check the Audit_Time of row 4 which is not < '01/05/2004'.
So I can't delete row5.
Is there any way to check previous row or the row before a specific row in SQL.
Any suggestion is welcomed.
Thank you in advanced.
Check Table Recordcount Before Run Of DTS Pkg
Sep 12, 2006Hi,
Could someone shed some light on the best way to check a table recordcount before run of DTS pkg.
We have a table that is populated in MS SQL from an Oracle database, and the contents of that table are the basis of a DTS package that we run.
Sometimes Oracle transfer bombs out and the table is empty but our process runs anyway. It screws everything up.
Can we check the recordcount of a table on the server, and if the recordcount > 1 then the process runs, if not, then the process aborts?
Thanks,
