I am trying to make a where clause using the sql server unique record id that is set automatically when a record is inserted. It is the record id that is unique for one table.
In a where clause. What type should go where the _______ is below?
<html>
<head>
<title>
</title>
<script language="vb" runat="server">
sub page_load(sender as object,e as eventargs)
response.write(request.queryString("a"))
response.write(",")
response.write(request.queryString("b"))
get1.text=request.queryString("b")
end sub
sub star(sender as object,e as eventargs)
dim connection1 as new sqlconnection("")
const q1 as string="update tbltest set code=@code where dxid=@dxid"
dim command1 as sqlcommand=new sqlcommand(q1,connection1)
command1.parameters.add("@code",sqldbtype.varchar).value=get1.text
command1.parameters.add("@dxid",sqldbtype._________).value=request.queryString("a")
I HAVE THREE TABLE GEN, PARTY, TXN (GEN & PARRTY IS MASTER TABLE AND TXN IS TRANSACTION TABLE) IN TXN TABLE - STORE ALL DATA IN WHICH SAME VOUCHER NUMBER IS REPEATED ACCORDING TO JOURNAL ENTRY) NOW PROBLEM IS THIS AT THE TIME OF DISPLAY THE RECORD ON SCREEN I HAVE TO SHOW ONLY THE UNIQUE VOUCHER NUMBER ONLY..
PLS GUIDE IN THIS QUERY HOW CAN I GET THAT RESULT.
SELECT DISTINCT TXN.VOUCHER, GEN.GLNAME, PARTY.PARTYNAME, TXN.DOCDATE, TXN.GLCODE, TXN.PARTYCODE, TXN.AMOUNT, TXN.VTYPE, TXN.CBCODE, TXN.ADJ, TXN.DC, TXN.NARR FROM (TXN LEFT JOIN GEN ON GEN.GLCODE=TXN.GLCODE) LEFT JOIN PARTY ON PARTY.PARTYCODE=TXN.PARTYCODE WHERE TXN.VTYPE='JV' ORDER BY TXN.VOUCHER
I have result set as the attached in screenshot, where the candidateid gets duplicated, but then the column university and careerchoice column has different values for the same candidate. (the CareerChoice and University comes from different tables and i have used union clause)
What want is e.g. CandidateId 186 repeats three times, it should be one row, with three columns all filled with the values which are in different rows.
So that I don't have duplicate candidate ids and i have single row with all column data.
I have a stored procedure (below), that is supposeto get a Reg Number from a table, (Reg_Number), insuch a way that every time the stored procedure is called,it will get a different reg number, even if the storedprocedure is called simultaneously from two differentplaces,However it is not working that way.If two different users access a function in thereVB program at the same time, the two different userswill get the same reg number.I have looked at the stored procedure, it looks foolproof,yet it is not working that way.Thanks in Advance,Laurence NuttallProgrammer Analyst IIIUCLA - Division of Continuing Education'---------------------------------------------------------------------------Here it is:CREATE PROCEDURE sp_GetNextRegNum@newRegNum char(6) = NULL OUTPUTASLABEL_GET_ANOTHER_REG:Select @newRegNum =(select min(Reg) from reg_number)IF Exists (select Reg from reg_number where reg = @newRegNum )BeginDelete from reg_number where reg = @newRegNumIF @@Error <> 0BeginGoto LABEL_GET_ANOTHER_REGEnd--EndifEndELSEGoTo LABEL_GET_ANOTHER_REG--EndifGO
I am new to SQL but trying to do join a few tables to get result showing showing one row per unique record.
Tables include:-
1. REQ 2. RFQ 3. PO 4. DOCUMENT (contains LAST_DOCUMENT_STATUS, DOCUMENT_ID, DOCUMENT_NUMBER, for example, REQ_CANCELLED, REQ_ID, REQ_NO) 5. DOCUMENT_STATUS (contains status of document, REQ_CREATE) 6. DOCUMENT_TRAIL (contains link between documents, PARENT_DOCUMENT, CURRENT_DOCUMENT, for example, REQ_ID (PARENT_DOCUMENT), RFQ_ID (CURRENT_DOCUMENT) 7. PO_REVISION (contains PO REVISION, when link with DOCUMENT, PO_REV_NO)
Currently when i tried to join all the TABLES, i get multiple lines against REQ_NO.
I realised the multiple lines generated due to the following:-
One to many relationships: A. RFQ - 1 or more PO B. PO - 1 or more PO_REVISON
I was thinking how to MAX the records in PO to show only the last PO_REVISION. It seems that DOCUMENT_TRAIL will contain 1 base document PO and 1 or more PO_REVISION.
Hi all,We have an app that uses SQL 2000. I am trying to track when a code field(selcode) is changed on an order which then causes a status field (status)to change. I tried a trigger but the app may use 2 different updatestatements to change these fields depending on what the user does. When thetrigger fires (on update to selcode), the status field has already beenchanged. So my trigger to record the changes from inserted and deleted donot get the true 'before' value of the status field.The app does use a log table that tracks these changes. The problem I amhaving is that 2 records are created, one for the change to selcode andanother for the change to status.I am looking for help with a script to combine the existence of these 2 logrecords into 1 unique record or occurance that I can track.example:ordlog: table that logs order changesordernr: order numbervarname: name of field being changedold_value: contents of field before changenew_value: contents of field after changesyscreated: date/time of log entrySELECT ordernr, varname, old_value, new_value, syscreatedFROM ordlogwhere varname = 'selcode' and ordernr = '10580'SELECT ordernr, varname, old_value, new_value, syscreatedFROM ordlogwhere varname = 'status' and ordernr = '10580' and old_value = 'A' andnew_value = 'O'So I need a way to combine these 2 log entries into a unique occurance. Theordernr and syscreated could be used to link records. syscreated alwaysappears to be the same for the 2 log entries down to the second. Selcodecan change from NULL to a number of different values or back to NULL.Statusis either 'A' for approved or 'O' for open. An order can have many logentries during its life. The selcode may be changed several times for thesame order.Ideally, I would like a result that links 2 log entries and shows the statuschanged from 'A' to 'O' when selcode changed.Thanks for your time.
I've been searching and trying out SQL statements for hours and I'mstill having a problem.I'm querying 3 tables... and I only want the first unique recordreturned.Currently, the data returned looks like this..............New York New York ANew York New York BNew York New York CLos Angeles California ALos Angeles California BLos Angeles California CI want the select statement to return this instead...New York New York ALos Angeles California AI'm using MS SQL server.please help?thanks for your help.
Hello, I am working with a database that among other things uses multipart keys as the unique indexes which are not consistent from say one table where a parent record resides to another table which contains related child records. For example I am working with two tables right now, one that contains content that I'll call Contents and the other which contains Usage information about the contents (number of view, a rating and comments give by a customer) which I'll call ContentsUsage. The system that manages the data for the tables has a versioning system by which, whn a content item is added (first time) a "unique" id (guid) and a version number of 1 is created along with the rest of data items in the Contents table and likewise in the ContentsUsage table (essentially a one to one mapping) on the like named fields in that table. Now, each time a given record in the Contents table is updated a new version, with the same guid is created in the Contents and ContentsUsage table. So one side I have:ContentGUID > AAAAVersion > 1ContentGUID > AAAAVersion > 2And the other table (ContentsUsage)ContentGUID > AAAAVersion > 1ContentGUID > AAAAVersion > 2 While both of these tables have a quasi-unique record (row_id) of type char and stored as a guid neither obviously are the same in the two tables and having reviewed the database columns for these tables I find that the official unique key's for these tables are different (table 1, Contents combines the ContentGUID and Version) as the composite / mutli-key index, while table ContentsUsage uses the RowGUID as it's unique index. Contents RowGUID (unique key)ContentGUIDVersionViewsRatingComments................RowGUID ContentGUID (unique key)Version (unique key)Description..... Bearing this in mind I am unable of course to link directly the two tables by using the just the ContentGUID and have to combine the additional Version to I believe obtain the actual "unique" record in question. The question is in terms of writing queries, what would the most efficient query be? What would be the best way to join the two in a query? And are there any pitfalls with the current design that you can see with the way this database (or specifically these tables are defined)? It's something I inherited, so fire away at will on the critique. Having my druthers I would have designed these tables using a unique key of type int that was autogenerated by the database. Any advice, thoughts or comments would be helpful. Thanks,P.
Hello Hello, This Noob has a question. I have been atempting for days to figure this out. I have this set up: (See Below)
The Problem I am having is occuring at the Table named OU in Maroon below. It combines 2 chains of keys into one table to try and make a unique record. The problem is that it is not.
Pasted below is a Query run on the data within the tables: As you can see certain data is getting duplicated in this tabel. I want 1 Unique record in the OU table based upon the Study ID Primary Key and the zCombined Primary Key.
Any Ideas as to what is wrong, or how to make it work would defineatly be appreciated.
Table:zCombined PK: zCombinedID FK: TempID ~ To Temp Table FK: ShipTypeID ~ To Ship Type Table FK: CoordinatorID ~ To Coordinator Table FK: BoxTypeID ~ To Box Type Table
can someone pls show me a way to get an unique sequence at below senario:
PC1 & PC2 using their own local client progam to access to Database Server at SERVER1. In the SERVER1, there is a table SEQUENCE in a database DATABASE1. And the table's structure of SEQUENCE are SeqType & SeqNo. Here is the sample data:
SeqType SeqNo Invoice 100 DeliveryOrder 200
Now, how to prevent PC1 & PC2 to get a same Invoice No. if they request the Invoice No. at the same time? Is it possible to lock the record Invoice when i perform a SELECT statement, then i update the Invoice to 101, lastly release the lock for Invoice?
I am running a proc (PROC1) that gets one record at a time and does some work against it.
select min(myid) as NextID from tbl_ListOfThingsToDo where AlreadyDone is null
Then once I have the MyID, I set the 'AlreadyDone' bit to True so that no one else picks that record up.
update tbl_listofThingsToDo set AlreadyDone=1 where MyID=(from above)
If there is only one PROC1 running, this is no problem. He just keeps grabbing the next record to operate on.
--but--
If I kick off multiple instances of PROC1 for scaleability reasons, how can I make sure that only one instance gets the next record? For example, couldn't the second instance get the same myid BEFORE the first instance has written that he already got it?
Design is to run 3-5 instances of this to get extra cycles.
Id StdId TeacherName Day subject 1 1 Archana Monday English 2 1 Archana Tue Marathi 3 1 Shama Wed Hindi 4 1 shama Thus Hindi 5 1 Kavita Fri Hindi 6 2 Archana Mon english 7 2 Dipti Tues Hindi
Second table : Student
Id Sname Cid 1 Shalini 1 2 Monika 1 3 Rohan 3
I want to fetch uniq combination of stuid and subject.Result should show all subject of student whether may be teachername and day. If I choose shalini whose stuid is 1,all subject for shalini(hindi,english,marathi) should come. Record from either of three should come
Id StdId TeacherName Day subject 3 1 Shama Wed Hindi 4 1 shama Thus Hindi 5 1 Kavita Fri Hindi
I want fetch studentname along with teachername,day and subject whose cid = 1 here is my query
select Student.Sname,TeacherName, Day,subject from StudentTeacherRelation inner join Student Student.id = StudentTeacherRelation.StuId where cid = 1
I want place result of it in temp,Want fetch max(id) from temp table by doing group by on Sname and Subject.find all id from temp table where that id present in max id.
show Id StdId TeacherName Day subject where (1,2,3,4,5,6,7-- all id from temp) in (1,2,5,6,7 -- max id from temp by doing group by on Sname and subject)
So it will show record Id StdId TeacherName Day subject where id is 1,2,5,6,7.Only five record should come.How to do that?
I am looking to create a script that will go through a table a pick out the necessary columns to create a unique record. Some of the tables that I am working with have 200 plus columns and I am not sure if I would have to list every column name in the script or if they could be dynamically referenced. I am working with a SQL server that has little next to no documentation and everytime I type to mere some tables, I get too many rows back.
I have 251 distinct types and I wish to return 1 meternumber for each type of metertype?
So far I have the folloiwng query to return the 251 distinct metertypes but i also wish to return a meternumber for the 251 metertypes. Both columns are in this table.
Hi, I have a doubt about the behaviour of SQL Server 2005 in the situation I'm going to describe you. Suppose that you have a SQL Server 2005 database on your PC, and suppose that this database has a table with a column classified as "unique" (so it's impossible for this table to contain 2 records having the same value in this column). Suppose that you publish this database and you create 2 SQL Server Mobile 2005 subscriptions on 2 Pocket PCs. Suppose now that the first PPC (using an embedded program) creates a record with a certain value for the column (and adds it to the table), and the second PPC makes the same thing (it inserts a record with the same column value of the first PPC). At this point, you connect the 2 PPCs to your PC (one by one, of course), to synchronize (using merge replication) the databases...
WHAT HAPPENS??? Does an error raise? Must you give a publication setting in which you say that, if this situation occurs, PC SQL Server holds the last (or the first, as you decide) record acquired? Is it possible?
Hi,I want my application to audit any data changes (update, insert,delete) made by the users. Rather than have an audit table mirroringeach user table, I'd prefer to have a generic structure which can loganything. This is what I've come up with:TABLE: audit_record*audit_record_id (uniqueidentifier, auto-assign, PK) - uniqueidenfiier of the audit recordtable_name (varchar) - name of the table where the action (insert/update/delete) was madepk_value (varchar) - primary key of the changed record. If the PKitself has changed, this will store the old value.user_id (varchar) - user who changed the recorddate (datetime) - date/time at which the change was madeaction (int) - 0, 1 or 2 (insert, update, delete)TABLE: audit_column*audit_record_id (uniqueidentifier, composite PK) - FK tocdb_audit_record table*column_name (varchar, composite PK) - name of the column with changeddatanew_value (text?) - value after the changeSo every column which changes has its new value logged individually inthe audit_column table. However, I'm not sure what data type thenew_value column should have. The obvious answer (to me) is text, asthat can handle any necessary data type with the appropriateconversion (we don't store any binary data). However, this table isgoing to grow to millions of records and I'm not sure what theperformance implications of a text column will be, particularly giventhat the actual data stored in it will almost always be tiny.Any thoughts/recommendations/criticism would be greatly appreciated.ThanksAlex
I got some issues regarding selecting the most recent record from a datetime type column. The probelm consists in following: Table: News Needed columns: Letter [varchar] DateTimePublication [datetime]
The ideea is that there are letters with the same name [Letter] but different DateTimePublication ... and I need only the letters with the most recent DateTimePublication for every letter type like FR_dd_mm_yy/EN_dd_mm_yy/DU_dd_mm_yy.
I am currently working on project where I need to insert, delete and update data from a text file I receive into multiple tables. So the file has multiple recordset types(50 to be exact) and each record has a a code to perform an -Update, Insert, or Delete to the destination table. Also when I receive the records they are not sorted. I need to sort the sets for each destination table and then read the the sorted set sequentially and perform the correct action.
Currently I am importing the record via flatfilesource into one column. I am using a script component here that would consist I guess 50 outputs including the fields needed for each table. The outputs are sorted by sortkey field and when I add the record to the output I perform data type transforms needed for each field(most are strings but I need to convert some dates, numbers ect..).
***is there a better way of accomplishing this?***
(ps. I could use the conditional split and the derive column into the 50 different table but it was giving me errors that were almost forcing me to use a nvarchar type instead of a varchar type during some of the field transformations.)
At this point I would need to read through each of the outputs sequentially and perform the update, insert or delete into the needed table. Would I have to create 50 script components with an ADO.net recordset adapter to update the tables for each of the outputs? I am hoping you can help come up with a better way to accomplish all of this.
Also if I do need to update the tables with the script component could someone point me to an example of how to programmatically accomplish that. Thanks for any help of suggestions that you may provide as I am feeling kind of stuck.

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.
What's the difference in the effect of the followings: CREATE UNIQUE NONCLUSTERED INDEX and ALTER TABLE dbo.titles ADD CONSTRAINT titleind UNIQUE NONCLUSTERED
I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?
I have table "Clients" who have associated records in table "Mailings" I want to populate a gridview using a single query that grabs all the info I need so that I may utilize the gridview's built in sorting. I'm trying to return records containing the next upcoming mailing for each client.
The closest I can get is below: I'm using GROUP BY because it allows me to return a single record for each client and the MIN part allows me to return the associated record in the mailings table for each client that contains the next upcoming 'send_date'
SELECT MIN(dbo.tbl_clients.client_last_name) AS exp_last_name, MIN(dbo.tbl_mailings.send_date) AS exp_send_date, MIN(dbo.tbl_mailings.user_id) AS exp_user_id, dbo.tbl_clients.client_id, MIN(dbo.tbl_mailings.mailing_id) AS exp_mailing_idFROM dbo.tbl_clients INNER JOIN dbo.tbl_mailings ON dbo.tbl_clients.client_id = dbo.tbl_mailings.client_idWHERE (dbo.tbl_mailings.user_id = 1000)GROUP BY dbo.tbl_clients.client_id The user_id set at 1000 part is what makes it rightly pull in all clients for a particular user. Problem is, by using the GROUP BY statement I'm just getting the lowest 'mailing_id' number and NOT the actual entry associated with mailing item I want to return. Same goes for the last_name field. Perhaps I need to have a subquery within my WHERE clause?Or am I barking up the wrong tree entirely..
Hi everyone, I need urgent help to resolve this issue... As far as the performance goes which one is better.. Unique Index(col1, col2) OR Unique constraint(col1, col2) ? Unique constraint automatically adds a unique index and unique index takes care of uniqueness then whats the use of unique constraint ?
BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?
hi team, .Can i create umique constraint with out unique index.when i am creating a unique constraint sql creates a unique index (default) can i have only unique constraint ?
I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today. Here is the code
Code Snippet create procedure SearchPartKeyword ( @Keyword varchar(250) = null, @Universal_Id varchar(10) = null ) as select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM, p.Legacy, p.Folder, p.Printer from Parts p inner join notes n on p.PartNumber = n.Identifier where n.Universal_ID = @Universal_ID and p.Description like @Keyword union select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly, p.DMM, p.Legacy, p.Folder, p.Printer from Parts p where p.Description like @Keyword
and the results: PartNo Description SO Notes LA DMM Legacy Folder Printer de90008 MAIN BOARD 1 DGF1 114688 0 0 0 de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
create table Test ( [recId] [int] identity(1, 1) not null, [code] [varchar](50) not null, [prime] [bit] not null constraint [DF_Test_prime] default (cast(0 as bit)), constraint [PK_Test] primary key clustered ( [recId] ) with fillfactor = 90 on [primary] ) on [primary] go
insert into Test (code, prime) values ('AVA', cast(1 as bit)) insert into Test (code, prime) values ('BUS', cast(1 as bit)) insert into Test (code, prime) values ('BUS', cast(0 as bit)) insert into Test (code, prime) values ('BUS', cast(0 as bit)) insert into Test (code, prime) values ('CAR', cast(1 as bit)) insert into Test (code, prime) values ('CAR', cast(0 as bit)) insert into Test (code, prime) values ('RLW', cast(1 as bit)) insert into Test (code, prime) values ('RLW', cast(0 as bit)) insert into Test (code, prime) values ('RLW', cast(0 as bit))
select * from Test
I need to create a constraint on this table that will not allow me to have two rows that are prime for the same code. So the following insert statement should fail:
-- This should fail insert into Test (code, prime) values ('RLW', cast(1 as bit))
I have a client who needs to copy an existing sale. The problem isthe Sale is made up of three tables: Sale, SaleEquipment, SaleParts.Each sale can have multiple pieces of equipment with correspondingparts, or parts without equipment. My problem in copying is when I goto copy the parts, how do I get the NEW sale equipment ids updatedcorrectly on their corresponding parts?I can provide more information if necessary.Thank you!!Maria
