I need to to have a table that has a counter field (used to generate an id code for a record). This is not the primary id for the field but just a counter to label a record in another table, similar to a registration code for an event. This is a sequential counter that will start 1 and go up on each new record inserted into other tables. What I want to do is be able to query this counter table to get the next valid number and increment the count for the next time. This is a multi user web app so needs to prevent duplicate use of same number.How best should this be handled? A transaction to query and update the field?
I would like to store some frequently asked questions in a database. As those questions/answers could be translated in several languages, I was thinking of using two tables :
The first table would contain a unique field : the key wich is an id for each faq.
The second table would contain those fields : FAQ_ID : foreign key LANG : language QUESTION : the question translated in the good language. ANSWER : the answer translated in the good language.
What I find embarrassing, is that first table just contains a unique field : the id. But it allows : - to have a table in which a line correspond to an object. It is convenient for object relational mapping. - it is more evolutionary. If, in the future, I have to add some statistics that concerns a faq, I will have the possibility to store them in the first table, avoiding in this way to duplicate data.
But, one more time, I find a bit embarrassing having a table with a unique field...
I'm new to MS SQL and VB. I have a table with one field JOB_NAME containing 20 records. Out of that field I want to retrieve 6 of the 20 records into a pulldown menu. They are all unique text names like so:
Anna Smith John Doe
etc. I did not see IDs listed for any of the names in the table when I looked.
There is no common denominator to the names that can be filtered in the SELECT statement, and the 6 that I want will need to be pulled out individually.
Is there a way to do this with a SELECT statement? I have not found much information about how to extract unique records out of a single field. Here's the statement I'm using which pulls all of them:
strSQL = "SELECT DISTINCT JOB_NAME AS Names FROM [WORKER_NAMES] WHERE JOB_NAME<>' ' ORDER BY JOB_NAME ASC"
This gives me the total list but I only want to bring back 6 of the 20 for the pulldown.
Is there a way to modify this statement to pull only the records that I want?
I have a table with fields name Days1, Days2, Days3 - I am trying to use a loop in conjunction with a counter to identify each of these fields - I can't quite get the correct syntax and it is driving me crazy!!!
Here's the proc:
WHILE @Counter < 4 BEGIN
SELECT @AppointmentsCount = COUNT(tbl_SurgerySlot.SurgerySlotKey) FROM tbl_SurgerySlot INNER JOIN tbl_SurgerySlotDescription ON tbl_SurgerySlot.PracticeCode = tbl_SurgerySlotDescription.PracticeCode AND tbl_SurgerySlot.Label = tbl_SurgerySlotDescription.Label LEFT OUTER JOIN tbl_Appointment ON tbl_SurgerySlot.SurgerySlotKey = tbl_Appointment.SurgerySlotKey AND tbl_SurgerySlot.ExtractDate = tbl_Appointment.ExtractDate WHERE (tbl_SurgerySlot.ExtractDate = @ExtractDate) AND (tbl_Appointment.AppointmentKey IS NULL) AND (tbl_SurgerySlot.StartTime > @DateFrom) AND (tbl_SurgerySlot.StartTime < @DateTo) AND (tbl_SurgerySlotDescription.IsBookable = 1)
SET @FieldName = 'Days' + CONVERT(VARCHAR(20),@Counter)
INSERT INTO tmp_Availability (@FieldName) VALUES (@AppointmentsCount)
SET @DateTo = DATEADD(Day,1,@DateTo)
--Increment the loop counter SET @Counter = @Counter + 1
When I run the above the follwoing message is displayed:
Server: Msg 208, Level 16, State 3, Line 36 Invalid object name 'tmp_Availability'.
Using MSSQL (pre 2005): I have a Link table: int id (primary key/identity) varchar(50) linkName varchar(255) linkHref //some other stuff and my Hits table: int id (primary key/identity) int linkId (foreign key to Link) datetime dateCreated //some other stuff Hits gets an insert whenever a link is clicked. (All this works just fine) I'm trying to create a report that shows each link by its name and href, a counter and the last date each link was visited. What I currently have is an accurate listing for those that have been clicked on, but it does not show anything for links that haven't been clicked on. Any suggestions as to how I can modify the following SQL to return "0" and "never" (or DBNULL) if no entries are found in Hits that have the same id? Or do I have to do this in a couple queries? SELECT COUNT(h.id) as counter, MAX(h.dateCreated) as lastVisited, l.id as id, l.linkName as linkName, l.linkHref as linkHref FROM Link as l INNER JOIN Hits as h ON l.id=h.moduleId GROUP BY l.linkName, l.id, l.linkHref
I posted a thread in the Getting Started forum about how to make a counter for maximum tickets : http://forums.asp.net/t/1215258.aspx but maybe this is a more appropriate forum for this subject. In a school project, we are making a website for a fictional concert/festival (using Visual Studio 2005, C#). On that site users can register and order tickets. We have access to an SQL-database, by the way, where we can create tables etc. We want the maximum amount of tickets to be 10000 per day. The festival is supposed to last from friday to sunday. What would be the best way to do this programatically? The counter should maybe be in an own database table?
I have a database table with a primary key that auto-increments - using MS SQL Server 2000. However I have another field (standard field) that must not allow duplicates.
Besides writing code to sift through the database every time to check for duplicates (which would take long to search through the db every time), is there any setting in MS SQL Server 2000 that allows for an automatic check for duplication and will prevent duplicates!??

I have everything created, with data already in the table. What I need now is some way to prevent duplicates from occurring. The Entry_Sheet value needs to be unique. Instead of writing code to run through the entire db each time an insert is performed, is there a simpler way using a SQL Server DB!??
I know that TRUNCATE TABLE can be used to reset the identity counter, but it can't be used on a table referenced by a foreign key. Anybody knows how to do that? Thanks.
1. Example data with Diag Code = null ABCD1234ABCDEF1234567MEDI19921301
2. Example data with Diag Code <> null ABCD1234ABCDEF1234567MEDI19921301708.1
This runs fine in Access and if the Diag Code is null, Access does not care, it still puts all the other information together. Such as the examples above.
Well I tried doing this in a Stored Procedure and when I ran across a record that had a null value for the [Diag Code] it made the IndKey field Null for that record. If it was not null then it looked like Example 2.
What is the proper way of creating my unique field in SQL Server?
I have a table where the key is an autonumber. I also have a field which holds the reference of a room eg 0BM1. It is nvarchar. Is there a way I can set this field to duplicates = No, so that my user cannot enter the same room reference more than once. Or do I have to do this check in my asp.net code ?
Is it possible to have the field as a unique key and a optional one?It is like.. for example, office code has to be unique (cannot beduplicated with the same code) and it could be null too.
I have a table in Access 2007 that has about 30 field names and I want to have a count of how many unique rows there are in each field. I want to have these results put into another table that will just have the field name and then the count of how many unique rows there are.
I have code in VBA that will loop through my SQL and change out the field name, but I can't seem to get the SQL right before I can start looping it. For just one field name this would be what I have to count the unique names...
So far I have this:
INSERT INTO newtable COUNT(*) FROM (SELECT Raw_Table.FieldName, COUNT(Raw_Table.FieldName) AS CountOfFieldName FROM Raw_Table GROUP BY Raw_Table.FieldName);
SQL 2000 Enterprise Manager won’t let me drop a unique key index and move it to another field. I get an error regarding ‘drop index not allowed because of unique key constraint enforcement.
Is there anyway to change fields for unique keys in SQL Enterprise Manager?
I created a view that joins two tables (tblOrder and tblProduct). The fieldProductID is common to both. When I save the View I get the following errormessage: "Column names in each view must be unique." Is there a way aroundthat? Should I be naming my Key Fields and Foreign Key fields differently?I'm new to MS-SQL. Thanks for your help.Louis
I have one table which is using to keep 10 difference type of serial number (that mean i got 10 column in the table). Is there any way to do unique key checking (individually, not combine) on these 10 serial number without sacrify the performance?
I am in a situation where I need to find out unique field names with different values in a table having 200+ columns. Let's say I have two rows with 200+ columns ( I exported these rows from Lotus Notes to SQL Server) I am not sure what columns makes unique of these rows. It's going to be tedious by checking each column values. Is there anyway I can write a squl query on these two rows which outputs column names which are having unique values. I would appreciate If anybody gives me hint about achieving desired result
I have created a view based on joining 3 tables, however, it is not possible to have a unique field in the view which I must need it and I must create index on some other fields. Is there any way to create sequence number or uniqie field in mssql view.
I am working on a software primarily related to accounting with visual basic
Many of the problems and proposed several solutions for running sum, but I have read almost all of these interpretations,
have applied when running sum is a unique ID field. but almost all of the functioning of accounting reports are in chronological order. So he questioned what was the balance on 05.05.2012.
ID of the process is done, if the user enters a process backward a few things since then, the transaction date is old, but the ID is new, are experiencing problems. eg
ID DATE DEBIT CREDIT BALANCE
1 02.02.2012 100.00 0.00 100.00
6 04.04.2012 0.00 150.00 -50.00
3 02.05.2012 70.00 0.00 20.00
4 02.05.2012 80.00 0.00 100.00
2 06.06.2012 120.00 0.00 220.00
must balance the figure above.
if ID = 2 record, the record date 06/06/2012 and if the ID = 6, date 04/04/2012, the date the order is made if the listing is experiencing trouble getting balance. 2 records in the same day when the balance at worst formula breaks down. The big point is that I hang out in my project.
the only solution is to use a temporary table or writing about it in Visual Basic seems to calculate. the use of temporary table is not a solution, but unfortunately also very fast.
I have a very large CSV file containing name-and-address information which I am reading in a Visual Basic project using the Microsoft.JetOLEDB.4.0 provider.
The key field on which the CSV file is to be filtered is the PostCode field. This is a UK-format PostCode "XXnn Nxx" where "XX" is one or more letters denoting a geographical area within the UK and "nn" is one or more characters (starting with at least one numeric digit) which when combined with the area code denotes a specific district within the geographical area. My aim is to identify all the unique UK postal districts held within my address CSV file.
Because I do not know how to use SQL to filter on the partial contents of a database field I am presently reduced to extracting unique full PostCodes using "SELECT DISTINCT PostCode,City,County FROM [ADDRESSES.csv]" into a DataTable object, then sequentially reading that DataTable using the operation of a dictionary object to identify unique PostCode areas, to finally construct the DataTable I need.
Is it possible in SQL to select records where the value of a varying number of characters before a space character in a given (PostCode) field is unique?
So for years I was using the int identity(1,1) primary_key for all the tables I created, and then in this project I decided, you know, I like the uniqueidentifier using newsequentialid() to ensure a distinctly unique primary key.
then, after working with the php sqlsrv driver, I realized huh, no matter what, i am unable to retrieve the scope_identity() of the insert
So of course I cruised back to the MSSMS and realized crap, I can't even make the uniqueidentifier an identity.
So now I'm wondering 2 things...
1: Can I short cut and pull the uniqueidentifier of a newly inserted record, even though the scope_identity() will return null or 2: do I now have to add a column to each table, keep the uniqueidentifier (as all my tables are unified by that relationship) and also add a pk field as an int identity(1,1) primary_key, in order to be able to pull the scope_identity() on insert...
I have a list of movies that show throughout the year. I would like to assign a unique numeric identifier to each text field.
I have provided some sample data with the output I would like. The Movie_ID in the sample data is just made up, feel free to assign any numeric identifier, preferably of the same length but not a necessity.
I ran into an interesting situation. I'm working on contract and was looking at creating an ERD for an existing database when I ran into a problem. I found FK's that are referencing columns that do not have a unique constraint or a unique index.
I don't know the history of the database but was there a time in SQL Server history where this would have been possible? I scripted out the tables and created it in a test database. When I run the script to create the FK I get the following message.
I double checked the original tables and this FK does exist in table1 and there is no unique anything in the referenced table, table2. Currently the database is running on SQL Server 2008 Ent.
ALTER TABLE [dbo].[table1] WITH CHECK ADD CONSTRAINT [FK_table1] FOREIGN KEY([Col1]) REFERENCES [dbo].[table2] ([col2])
There are no primary or candidate keys in the referenced table 'dbo.table2' that match the referencing column list in the foreign key 'FK_table1'.
Hi guys, I need to get a column with the sum of the field "SUF" from table "JurnalTransMoves_1" when that field ("SUF") is ordered by the field "REFERENCE" from table "Stock", and Show the value only once.
The desired result should by something like:
Stock.REFERENCE JurnalTransMoves.SUF SUM(JurnalTransMoves.SUF) Group By Stock.REFERENCE
5752 10 60
5752 20
5752 30
5753 400 3000
5753 500
5753 600
5753 700
5753 800
5754 7 15
5754 8
Is there any chance to do that? Thanks in advance, Aldo.

[Code] ....
The above query returns me all messages (inbox functionality) that have been sent to mr.ReceipientId, the issue I have is when I send another email to the recipient the readdate field will be null, and the other emails linked to the recipient which have also been sent via me will have a readdate date. This causes duplicate rows to appear due to the case statement, I'm trying to figure out if / how it is possible to only display the one row per conversation and set newmessage to 1 if there is an un-read message otherwise show 0 ?
I have a comma separated field containing numerous 2 digit numbers that I would like splitting out by a corresponding unique code held in another field on the same row.
E.g
Unique Code Comma Separated Field
14587934 1,5,17,18,19,40,51,62,70
6998468 10,45,62,18,19
79585264 1,5,18
These needs to be in column format or held in an array to be used as conditional criteria.
I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables. * Get last 3 months data from source table. * Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.
