Im trying to delete duplicate records from the output of the query below, if they also meet certain conditions ie 'different address type' then I would merge the records. From the following query how do I go about achieving one and/or the other from either the output, or as an extension of the query itself?
SELECT

I am working on a model where I have a sales fact table. Each fact record has four different customer fields (ship- to, sold-to, payer, and bill-to customer). I have one customer dimension table that joins to the sales fact table four times (once for each of the customer fields above). When viewing the data in Excel, I would like to have four hierarchies (ship -to, sold-to, payer, and bill-to customer) within Customer.
Is there a way to build hierarchies within my Customer dimension based on the same Customer table? What I want is to view the data in Excel and see the Customer dimension. Within Customer, I want four hierarchies.

Is it possible to insert data into a temp table with data returned from a stored procedure joined with data from another table?
insert #MyTempTable
exec [dbo].[MyStoredProcedure] @Par1, @Par2, @Par3
JOIN dbo.OtherTable...
I'm missing something before the JOIN command. The temp table needs to know which fields need be updated.
I just can't figure it out
Many Thanks!

I have a table with almost a million rows, although it's quite slim with just ID, date, userID, JobID etc.
Now I want to the ability to add comments to some (probably less than 1%) of those lines.
The question is whether to create a separate comments table to join to it, or to create a comments field within the existing table? The comments field would obviously default to NULL, so wouldn't bloat the table unnecessarily if I add that field (right?), and would always be selected with the row from that table, so I'm leaning towards the latter alternative.
Any thoughts, words of warning?
Thanks

Hi seniors
there are two tables involve in replication let say table1 and replicated table is also rep.table1.
we are not deleting records physically in table1 so only a bit in table1 has true when u want to delete a record but the strange thing is that replication agaent report that this is hard delete operation on table1 so download and report hard delete operation and delete the record in replicated table which is very crucial.
plz let me know where am i wrong and how i put it into right way.
there is no triggers on published tables and noother trigger is created on published table.

Ok here goes. I have 3 tables, one holds case info, the 2nd holds possible outcome on the charges, and they're joined on a 3rd table (CaseOutComes). With me so far? Easy stuff, now for the hard part.
Since there's a very common possiblitly that the Case has multiple charges, we need to track those, and therefore, display them on a datagrid or some other control. I want the user to be able to edit the info and have X number of dropdowns pertaining to how many ever charges are on the case. I can get the query to return the rows no sweat, but ...merging them into 1 record (1 row) with mutiple drops is seeming impossible -- I thought about using a placeholder and added the controls that way, but it was not in agreement with what I was trying to tell it .
Any ideas on how to attack this?
Guys - sorry for the long post - hope it's clear

I want to update the startdate column (for all rows) so that when period is 0 then the new value
is a hardcoded value (say '01-Dec-2000') but for all other rows it takes the value in the
enddate column for the row of the previous column (with the same freq)
ie the startdate column for period 1 takes the enddate value for period 0 and so on for a particular freq
create table #periods (period int , startdate datetime , [enddate] datetime , freq int)
insert #periods ( period , startdate , enddate , freq)

Hello everyone, I have a query problem.I'll put it like this. There is a 'publishers' table, and there is a'titles' table. Publishers publish titles (of course). Now I want to make aquery (in MS SQL Server) that would return the last title published by everyof the publishers. Quite clear situation. But I can't make it work.If I use inner join (which I should, because I need data from both tables)then I get a result showing all publishers and all titles. What I want toget is all publishers, and only their last title, so I don't have more thanone line for the same publisher, and this line should contain publisherdetails and last title details.I tried using DISTINCT, but it works on a whole resultant row rather then acolumn, and since rows are all distnict (because they also contain columnsfrom titles) this didn't help me.What I can do is (in my application) first get a list of publishers, andthen loop through them selecting only the last title belonging to eachpublisher. I want to see if there is a way to accomplish the same thing withan SQL query (or maybe a stored procedure, view, or whatever). Anything ispossible, as long as it stays within SQL server and doesn't rely on theclient application.Of course, both 'publishers' and 'titles' tables have a primary key('publisherID', and 'titleID'), and 'titles' has a 'publisherID' columnwhich relates titles with publishers.Help :)

I have two tables - products and productpropertyvalue
I need to select multiple fields from the productpropertyvalue as it corresponds to the product id. The script I am using is
select a.id, a.productname, a.siteprice,
b.propertyvalue
from product a, productpropertyvalue b
where a.id = b.productid and propertyid=590
This allows me to extract only 1 propertyid. I need to make it add 3 other columns for propertyid=589, 617, 615
Any help solving this problem would be appreciated - thanx!

Hi,
This is probably straightforward but I'm not sure how to approach this problem.
I have 2 tables, one parent and a child.
The child table has a Quantity and a Price field and also a FK to the parent table.
I want the parent table to display its own row data along with the Total Cost of the child rows in the child table.
So it needs to multiply the price by the quantity but also do a sum of this calculated column.
To start off with I tried SUM( TOTALCOST ) and it didn't like it.
I've got an idea I might need to create a View but was wondering what is the standard way of doing something like this?
E.g.
Parent Table
PK TOTALCOST
Row 1 50
Row 2 5
Child Table
PK FK Quantity Price TOTALCOST
Row 1 1 2 10 20
Row 2 1 3 10 30
Row 3 2 1 5 5
Thanks.

We currently have an application whereby the user will come along sign up add some information about them, choose what interests / hobbies they're in to and then click save.After completing the sigh up they're able to search for other individuals within locations (look at this functionality as a dating site) We currently have a stored procedure whereby when the user clicks Advance Search they fill in all the fields they filled in when signing up and when they click search we return all users that match the data the user has selected. This part is working correctly.
The issue im having is extending this stored procedure to take a user defined table type which has two columns UserId and ActivityId both columns are nullable.This user defined table type is referred to in two places, when the user signs up and when they do an advance search.When the user does an advance search he / she can choose a list of hobbies / interests this will then be passed in to the database and I will join on my User_Activities table to find the users that have the Activities passed in.When I join on this table I get duplicate records purely because one user may have 5 - 10 activities depending on how active the individual is. My current stored procedure looks like this
@Ambition int = null,
@Body int = null,
@Diet int = null,
@Drinking int = null,
@Ethnicity int = null,
@Exercise int = null,
@HeightFrom int = null,
[code]...
So my question is how can I select all users that match the criteria passed in, as well as finding the users that match the activities passed in (the user can either match all of them or a minimum of 1). Also my User_Activities has two columns UserId and ActivityId identical to the user defined table type

Here's my problem:I'm developing an ASP.NET 2.0 application that has a user select one or moreauto manufacturers from a listbox ("lstMakes"). Once they do this, anotherlistbox ("lstModels") should be filled with all matching models made by theselected manufacturers. If lstMakes was not multi-select, I'd have noproblem. But in this case it has to be multi-select. The database is SQLServer 2005 which does not accept arrays as parameters. I've been told thatI have to create an XML document that will act as a filtered Manufacturerstable that I can join to my Models table in my stored procedure. Problem isI don't have the foggiest idea how to do this. I've seen some examples thatjust leave me scratching my head so I was hoping someone could look at whatI'm trying to do and show me how to do this. Thanks!

Table A has columns CompressedProduct, Tool, Operation
Table B in a differnt database has columns ID, Product, Tool Operation
I cannot edit table A. I can select records from A and insert into B. And I can select only the records that are in both tables.
But I want to be able to select any records that are in table A but not in Table B.
ie. I want to select records from A where the combination of Product, Tool and Operaton does not appear in Table B, even if all 3 on their own do appear.
This code return all the records from A. I need to filter out the records found in Table B.

Hello,
I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post.
I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table.
This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off.
So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining?
Thanks in advance,
Andy

Hello:
Need some serious help with this one...
Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...
Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.
The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.
This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.
So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?
The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.
Thanks!

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
DELETE FROM Broker_Rates
WHERE (Broker_Rates.BID <> Broker.BID)
Thanks
The requirement is: I should allow single row delete from a table but not bulk delete. An audit table should get updated if there is any single delete or single update. So I wrote the triggers as follows: for single and bulk delete
ALTER TRIGGER [dbo].[TRG_Delete_Bulk_tbl_attendance]
ON [dbo].[tbl_attendance]
AFTER DELETE
AS
[code]...
When I try to run the website, the database error I am getting is:Transaction count after EXECUTE indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing. Previous count = 0, current count = 1.
'****************************************************************************
Cmd.CommandText = "Drop Table Raj"
Cmd.ExecuteNonQuery()
Cmd.CommandText = "Select * Into Raj From XXX"
Cmd.ExecuteNonQuery()
'**************************************************************************
This generates error that Table already exist.
If Wait 1 sec then execute statement then it works fine.
Thanks in Advance

I have two tables that are related by keys. For instance,Table employee {last_name char(40) not null,first_name char(40) not null,department_name char(40) not null,age int not null,...}Employee table has a primary key (combination of last_name and first_name).Table address {last_name char(40) not null,first_name char(40) not null,street char(200) not null,city char(100) not null,...}Address table has a primary key (combination of last_name, first_name andstreet in which (last_name, first_name) reference (last_name, first_name) inemployee table.Now I want to delete some rows in Address table based on department_name inEmployee table. What is sql for this delete?I appreciate your help. Please ignore table design and I just use it for myproblem illustration.Jim
