Interesting Variation Of Duplicate Check Help Please
Feb 9, 2007
Good morning all,
I have been tasked with an interesting problem using SQL 2005. Simplified it looks like this: I have two tables both well over a million rows, totalling unrelated keys between the tables. I need to find records in table one that do not exist in table two, the twist is this, I need to find rows where the invoice number in table 1 does not exist at all in table 2 or where the invoice number exists but the timestamp associated with the invoice in table 2 is more than 10secs different than the invoice/timestamp in table 1. I'm fairly new to sql and, although I can do the really simple stuff, this one is over my head I'm afraid. Any help at all would be greatly appreciated. I would also like to hear any suggestions regarding books that might give examples of sql code at around this level of difficulty. Thanks in advance for your assistance! Paul
What I am trying to do is this. I have two tables that someone else created and now I have to fix there mess. Both tables have 3 like fields. I want to check and see if the ProjectNumber field from the Artifacts table does not find a match in the Projects table. If no match is found return the record from artifacts table.
Code:
SELECT * FROM Artifacts INNER JOIN Project ON Artifacts.ProjectNumber = Project.ProjectNumber WHERE Artifacts.ProjectNumber NOT IN (Project.ProjectNumber);
The next thing I have to do is insert a record of the three fields from the Artifacts table to the Projects table. Any help would be great.
I have this simple query But i want to check if the policy number appears more than once, I tried to use a count(RR.X_POLICY_NO)>1 in the where clause but i get an error, anybody have any suggestions?
Hi, Does anyone have any sugestions as to the best way to achieve the following? I want to display a list of products in a GridView. Against each product I want to place a button which will add the product to a "wish list" table. I need to be able to check that the product has not already been inserted into the wish list. Either suggested methods or links to tutorials will be appreciated. Thanks in advance.
Hi,I need to enforce that a table does not have "duplicates" for aspecific status type in the table.If the column "STATUS" = 2, then there can not be more than one rowwith a specific "ID" column.I can not use a unique key constraint because duplicate values for thiscombo of columns is valid for the status = 1.Just when the status = 2, there can not be any other rows with the sameID and status = 2.Any ideas?-Paul
I have a website where members can add new messages to the site. But now I put somoe restrictions that for each member can add messages only the specified time intervals. For eg:- for one member, I put the time interval is from 1 to 10 (its in hour format and datatype is varchar).Means this member can add messages in between the time 1 AM and 10 AM. Now how to check whether current time is in between 1 and 10.
I've got 2 servers and they are using replication to synch the data from one to other. I've got a Full Text Catalog on a table on both servers. - I repopulate the catalogs completely on both servers(now remember that the base tables of those catalogs are under replication and are exactly the same!!) -When I run the exact same qquery against the 2 databases using the Full Text Catalogs I'd just finished rebuilding, I get a different number of results returned in my result set on one then I do on the other... How the heck could this be possible?
When the database is configured for mirroring and you want to do partitioning on that database, How can we do? Is this similar process or any variation there while adding file groups and files? The partition will reflect in the mirroring database also?
Unfortunately, data wasn't filtered prior to getting inserted into this table. Now I am stuck with cleaning it up. I have thought about writing a query to update all the values, but there are just too many variations, including spelling mistakes, so I've ruled that out as a possible solution.
I have a table which has a Country field but the values per record vary. For example US, U.S., USA, United States, UK, United Kingdom, Canada, Can, etc. I'm trying to find the percent of records per country.
Sample table data: mytable Id Name Country 1 John US 2 James UK 3 Jane United States 4 Mary Canada 5 Jack U.S. 6 Tony United Kingdom 7 Jeff US 8 Tom Canada 9 Beth UK 10 Mark USA
I would like to show US: 50% --> (includes any variation of US ncluding US, U.S., USA, United States) UK: 30% CAN: 20%
I've made several attempts myself with no luck. Thanks in advance.
I have to create a table like this across a bunch of servers. I'm thinking that I'm overlooking something with needing two additional CTEs, but maybe not. I have it at 17 seconds, which isn't much faster than a while loop solution that's currently in place.
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.
Below is the statement given in MicroSoft SQL Server migration documentation :
"When a view is defined with an outer join and is queried with a qualification on a column from the inner table of the outer join, the results from SQL Server and Oracle can differ. In most cases, Oracle views are easily translated into SQL Server views"
Please can anyone explain the above with some examples. I don't find such a 'CREATE VIEW' statement existsing in two DBs, which results in different result set. Am I wrong ?
Another tech was having the same problem with his sp which he also made into a macro. He was having the same problem as I was, he thought since he made the user the dbo owner that he woud have no problems...but since hes the one who created the db and the stored procedures when the user tried to access it he got that same error message. It went away after he went into the Enterprise manager and in the properties of the stored procedure under permission he gave the user EXEC permissions...And WAAALLLAAA problem solved :):):):)
Anyone else experience this? A developer just finished complaining about the performance of one of our databases. Well, he sent me the query and I couldn't understand why it was such a dog. Anyways I rewrote it. The execution plan is totally different between the two. I had no idea specifying the join made such a difference. First sql executed in 7 minutes that 2nd took 1 second. SELECT dbo.contract_co.producer_num_id, contract_co_statusFROM dbo.contract_co, dbo.v_contract_co_statusWHERE ( dbo.v_contract_co_status.contract_co_id = dbo.contract_co.contract_co_id ) AND contract_co_status = 'Pending' OR ( contract_co_status = 'Active' and effective_date > '1/1/2004' )SELECT dbo.contract_co.producer_num_id, contract_co_statusFROM dbo.contract_co INNER JOIN dbo.v_contract_co_status ON dbo.contract_co.contract_co_id = dbo.v_contract_co_status.contract_co_idWHERE contract_co_status = 'Pending' OR ( contract_co_status = 'Active' and effective_date > '1/1/2004' )
I have a system in place currently that both a local and a live database, currently the sales database is kept in line with a home grown "syncronise" script that controls keeping the two tables (live and local) in sync with the use of Local and Remote ID'sFor example;Table "Sales"ID - IntRemoteID - IntVarious Data fieldsThe 'Live' System writes new records using the RemoteID field, whilst the local inserts new records using the ID field. The Sync script copies the data up/down and assigns the corresponding RemoteID/ID's to the records as they are copied accordingly.Its been decided that this process must change, in favor of Two Way Replication. I have been tasked with finding the solution to the safe handling of ID's as theres a danger that two people can be writing a record (one live, one local) and possibly create the same ID's - i know that replication has its own ID's and could probably manage this well on its own, but these 'Internal' ID's have to be unique due to business rules.So i have been considering two possibilities to address this problem,1. Staggering the ID's - for instance Live ID's begin at 1,000,001 and local ID's begin at 1.2. Having a controlling ID table which provides the next IDBoth options have their advantages and disadvantages, with option 1 we will run into a problem later when the local ID's reach the 1 million mark (a few years away, i admit) and option 2 will need careful locking/transactional code to ensure the same ID isnt given twice.Does anyone have experience with this kind of issue? or could suggest an alternative approach to this problem? Thanks in advance!
We've had an interesting server issue here since about the start of the year, where the dual processor Netfinity server we've been running SQL 7 on has been holding steady at almost exactly 50% CPU utilization, give or take about 5%-10%. Disk utilization in all areas is relatively low. In fact, the server will do this right after a fresh reboot, with no users accessing. The really interesting part is that a graph of the two processors mirror each other. When the utilization of one goes up, the other goes down, almost perfectly. The two processors are the same speed, but their firmware build is different. IBM says it's not a problem. What say ye?
Hi ! I am facing an interesting problem for one of my databases. When I double click on a particular table in Enterprise Manager, the Manage Tables window shows me only one or two fields from the table. (it does not show me all the fields). When I run sp_help <tablename> in isql, all the information is displayed. Why is there such inconsistency. It happens only on one particular database. I have run DBCC commands but still no help. Does anyone have any ideas on this. Thankx,
We're having to work with some legacy data. The tables in the so-called database seem to have way more nulls than actual data. One table appears to have around 100 or more columns in it. It has close to 40,000 rows.
This Db has pretty much 0 normalization present.
IOW, your worst nightmare.
Is there a way we could run a query that would return the total number cells inthat contain NULL and another that could return the total number of data-bearing cells so we could come up with a % or a ratio.
In this SQL query I get en error like this:Incorrect syntax near ','.SELECT SUM(mCount * mPrice), CONVERT(DATEPART(yyyy, mDate), varchar) + '.' + CONVERT(DATEPART(mm, mDate), varchar) AS DateSoldFROM salesWHERE mDate BETWEEN '9/10/2007 0:0:0' AND '1/10/2008 23:59:59'I think you it isnt necessary to show values in the table because it is a syntax error but I dont undertand how it can be incorrect...Thanks for help...Saren Taşçıyan
Imagine a table in Microsoft Sql Server 2000 named Pictures with threefields. A primary key ID(int), a Name(nvarchar) and a Picture(image)field.Lets put some records into the table. The first two fields as expectedwould take an int and a string. The third field is of type image.Instead of putting a bitmap in this field lets place an xml documentthat has been streamed into a byte array. The xml document woulddescribe the Picture using say lines. If the picture was that of asquare we would have four lines in the xml document. You could think ofthe xml document as something similar to vector graphics but thedetails are not relevant. The important fact is that the contents ofthe image field is NOT a bitmap but a binary stream of an xml document.Now imagine we have a reporting tool like Crystal Reports that can beused to report on this database table. Imagine we create a report byusing the three fields mentioned above. As far as Crystal is concernedthe first field is an int, the second a string and the third an image.If our table had ten records and we preview the report we like to see10 entries each consisting of an ID, Name and a Picture.This can only happen if the image field contains a Bitmap, but asmentioned above the field contains an xml document.Now my question...Can we write something in SQL Server 2000 (not 2005) to sit between thetable and Crystal Reports so to convert the XML document to a bitmap.The restriction is that we cannot use anything but sql server itself.The client in the above case has been Crystal Reports but it could beanything.I know SQL Server 2005 supports C# with access to the .NET frameworkwithin the database. Unfortunately, I am not using SQL server 2005.Some people have suggested the use of User Defined Functions and TSQL.I like to know from the more experienced SQL Server people if what I amtrying to achieve is possible. Maybe it has not been done but is itpossible?Any suggestions would be greatly appreciated...Many Regards
When I wanted to see ONLY today€™s records on the sql server, it took 5 minutes. When I wanted to see records including today€™s records on the sql server, no problem. (19 Sep. is a past date which is working properly) It is very interesting it takes 5 minutes to sort the lastday there is nothing wrong with the other days. I ran DBCC INDEXDEFRAG method but no change anything.
I am wondering about something, everyday at 22:00 pm we are getting backup. Is this process creating a difference between before getting the back up and after got the backups? It is really interesting issue. I do not know what I can say. It seems there is an issue with today€™s records. May be there are some locks on the today€™s records. I do not know. Why does not cause any issue for old dates but for current day ?

What can be reason for this issue and how can I solve it ?
I have a very simple SSIS package that imports data from ODBC source. There are two "Time" columns in source, but When this table is created in SQL2005, it give me "bigint"!!!
How can this happen?
I tried to import data to SQL2000, those two columns are created as "smalldatetime" properply.
I am making a report in Visual Studio..Now my question is,is there anyway that i can add a tab control for my rdl??Hope to here from anyone out there with a know how..Thanks guys!!
Having no more experience than reading books online, here is an interesting idea I would like to run by you guys and you can let me know if it is feasible or tell me I need to put the crack pipe down...
We are going to increase the number of disks in our SAN, and I was speaking with the SAN administrator and he mentioned the shuffling of logical drives to match the new space. He said he is going to have to go through quite a few combinations/permutations on figuring out the best configuration for what data goes on the old vs. new to get the optimal space.
Is this something that can be modeled out? I can write something that recursively figures it out, but why not explore fun ideas with tools that may be able to do it?
Hello, In the code SqlParameter dtDate = new SqlParameter("@date",SqlDbType.SmallDateTime,4); dtDate.Value=Convert.ToDateTime(Session["date"].ToString()); cmd.Parameters.Add(dtDate);where the @date parameter is defined as a SMALLDATETIME inside a stored procedure, I cannot use a function such as "Convert.ToSmallDateTime" and it seems a conversion from DateTime to SmallDateTime takes place anywhere within the code. Eventually it works but I wonder if everything's ok with this code. Is there anything wrong about it? Thanks
I have an interesting request. I would like to take a table such as:
date value ----- ----- 1/1/01 10.5 1/2/01 9.3 1/3/01 11.5 1/4/01 4.7 1/5/01 3.2
and calculate an average for each record, based on its own value AND the following two values. In other words, for the first record, I would take sum(10.5 + 9.3 + 11.5)/3 and put this into a third column in my table. I would then do the same for the next record: sum(9.3 + 11.5 + 4.7)/3. Thanks in advance!
