Selecting A Column From Multiple Tables

Feb 19, 2004

Hello,

Is it possible to get a list of rows from Multiple tables which have the same Column Name. I have 3 tables which comtain similar info
and I want to get a list of Names
the structure is

ID;Name;Address;Phone No.


I was thinking something along the lines of SELECT Name FROM TABLE1,TABLE2, TABLE3

But this does not work.

Is there a nice way of doing this with SQL or should I do code outside the SQL DB

Selecting On Multiple Tables

Aug 13, 2006

Hi there,I'm new to sql and thus I'm having problems with a specific query which Ihope you guys can help me with.Basicly I have a few tables which I'm trying to do a query on:Table groups contains information about specific groups e.g. "Windows" or"Unix".Table users contains information about specific users e.g. "a", "b" or "c".Table users_groups contain information about group relationship (a user canbe in multiple groups) e.g. (a, Windows), (b, Unix), (a, Unix).In this case user c is ungrouped.Now I'd like to find the users which does belong to group Windows and thosewho do not:select distinct username from users_groups where groupname = "Windows" orderby username asc;This works pretty well for finding users in the specific group. In this casethe result is a.However I'd like to get the opposite result (b and c) but I'm stuck.The problem is that I'd like a list of all users excluding those which arein "Windows"Here is a partial query:select distinct users.username from users left join users_groups onusers.username = users_groups.username where users_groups.username is nullorder by users.username asc;This only gives me those users who are not grouped at all. This mean thatuser b is not in those results.Please advise.Thanks in advance.-- Henrik

Selecting From Multiple Tables Avoiding Duplicates

Sep 6, 2006

Hi

I currently have two tables called Book and JournalPaper, both of which have a column called Publisher. Currently the data in the Publisher column is the Publisher name that is entered straight into either table and has been duplicated in many cases. To tidy this up I have created a new table called Publisher where each entry will have a unique ID.

I now want to remove the Publisher columns from Book and JournalPaper, replace it with an ID foreign key column and move the Publisher name data into the Publisher table. Is there a way I can do this without duplicating the data as some publishers appear several times on both tables?

Any help with this will be greatly appreciated as my limited SQL is not up to this particular challenge!!!
Thanks!

Hi,
I am having two tables Products and Transaction

In products I have ProductID and Description. (10 Records)
In Transaction I have ProductID, Lot, Quantity and ListID . ( 4 Million Records)

When I use the inner join between these tables as below query its taking lot of time to give output.

select ProductID, Desc, Lot, qty from Products inner join Transactions on Products.ProductID = Transactions.ProductID
where ListID = '9090909'

select * from Transactions TR where TR.ListID= '9090909' and TR.ProductID in

(select NDC from Products where Products.ProductID = TR.ProductID)

Any from can help me to get the description too at very few times.

Database Design Selecting Multiple Different Child Tables

Sep 19, 2000

I want to have a linking table say for example we call this a claim. Based on the claim number you need to relate to one of say 6 different types of claims. The types of claims related to their own individual parent table. (individual because each type of claim tracks completely different information) does anyone have an idea on how to set this up?

Sample Structure

table = Claim
Field 1 = ClaimTypeA_ID
Field 2 = ClaimTypeB_ID
Field 3 = ClaimTypeC_ID
Field 4 = ClaimTypeD_ID
Field 5 = ClaimTypeE_ID
Field 6 = ClaimTypeF_ID

The six field relate to the 6 different tables ID.

If I do this how do I store the data? put 0's in each of the claim types that are not used???

Any suggestions would be appreciated.

Identitly Column Across Multiple Tables

Mar 11, 2003

I have a system that uses 3 tables of the same schema to track status of a transaction:

table 1: submitted
table 2: pending
table 3: confirmed

Transactions are moved from one table to another when the transactions go through different states. How do I maintain a unique identity of a transaction across the 3 tables? Some transactions are added directly to confirmed. Having a counter table affects scalability and increase blocking! Please help.

How To Add A GUID Column To Multiple Tables In A Database Using A SQL Script

Mar 1, 2008



Does anyone have a script that can add a GUID Column to multiple Tables in a Database.

For example when a table has an Identity column like EmployeeID, a column called EmployeeGUID is added to the table. When a table has an Identity column like CustomerID, a column called CustomerGUID is added to the table. When a table has an Identity column like OrderID, a column called OrderGUID is added to the table.

I intend to implement replication in SQL Server 2005, so i want to add new GUID columns to all the table in my database before implementing replication

The SQL script below adds a column to a single table in a database. But i need a script that can add a column to all the tables in a database.

Thanks

USE ProductDB

ALTER TABLE dbo.Employees
Add EmployeeGUID UNIQUEIDENTIFIER ROWGUIDCOL NOT NULL DEFAULT NEWSEQUENTIALID()

Selecting Multiple Records By Multiple Filters...

Aug 13, 2006

Hey all,I am having some serious trouble getting the correct syntax for a select statement to work the way I need it, any help I could get on this would be greatly appreciated.I have a table called Units which stores computers and a table called Software which stores software. I have a bit field in Units called OEM, when this is set to true I don't want the select statement to pull this unit down when I am assigning software to other units.Here is my select statement: SELECT Software.SID, Software.SN, Software.Name, Users.First + ' ' + Users.Last AS 'Assigned User', Units.Make + '-' + Units.Model AS 'Assigned Unit' FROM dbo.Software LEFT JOIN dbo.Units ON Software.SN = Units.SN LEFT JOIN dbo.Users ON Units.UID = Users.UID WHERE (Units.OEM = 'FALSE') AND (Software.SN LIKE '%' + @SearchString + '%')Everything works as expected, unless of course the unit has no software assigned to it yet, it won't return it because its not tied to a Units.OEM field. Is there anyway to have it return ALL records that even arn't joined OR are joined but have OEM set to false?Thanks, let me know if I need to clear anything up.-Matthew

SQLCE V3.5: Single SDF With Multiple Tables Or Multiple SDFs With Fewer Tables

Mar 21, 2008

Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:


1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.

1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.

1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.

I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.

Thanks in advance for any help/suggestions,
Bob

Mar 18, 2008

I have a product table that has a productID column and a productName column. Then I have a productCategory table that associates productIDs with categoryIDs. And lastly I have a category table containing a categoryID and categoryName. I want to write a query that will return a table with three columns...productID, productName, and and calculated column containing the categories the product belongs to separated by a comma. A sample output would be...

ProductID____ProductName____Categories
1____________Green Flats____Footwear, Accessories, Women's Apparel
2____________Purple Belt____Accessories, Women's Apparel
3____________Pink Tunic_____Women's Apparel

If any of this isn't clear please feel free to write with questions.
So far I have this query -
SELECT Products.ProductID, ProductName, CategoryName FROM Products, ProductCategory, Categories WHERE Product.ProductID = ProductCategory.ProductID AND Categories.CategoryID = ProductCategory.CategoryID

This returns....
ProductID_____ProductName____CategoryName
1_____________Green Flats____Shoes
1_____________Green Flats____Accessories
1_____________Green Flats____Women's Apparel
2_____________Purple Belt____Accessories
2_____________Purple Belt____Women's Apparel
etc....

T-SQL (SS2K8) :: Selecting Top 1 From Multiple Ranges?

Mar 28, 2014

I have data like the following:

ID COUNTER DATA
1 10 BLAH
1 20 BLAH
2 10 BLAH
3 10 BLAH
2 20 BLAH
2 30 BLAH

What I want to return is:

1 20 BLAH
2 30 BLAH
3 10 BLAH

I want the top 1, having the highest counter from each ID. This is a highly simplified version of that I am pulling which also is between a date range, but same principle.

IE: SELECT * FROM Table WHERE ID in (SELECT DISTINCT ID FROM Table WHERE Date BETWEEN <date> AND <date>

I'd rather keep it in one statement if possible, but if I have to do it in multiple passes then so be it.

How would I create a select statement to select all rows from Package (PackageID, Destination, Source) where the CleintID=1 and the PackageID exists in pending packages with a status of 0?

Can this be done using a select statement or would I have to create a view? I'm not too sure!

Selecting Where Cloumn = Column OR Column = Value

May 29, 2008

Hi
I have a gridview with a sql data source and a few drop down lists where i choose values to sorth what i would like to retrive from the table. The problem im facing is that when i pass values to the database, i can sort out and retrive my items when both my listboxes have selected values.
But when i want to select everything from the table where the column = clumn or cloumn = value i dont get anything back.
I have 2 dropdown lists. One for category and one for location. These are populated drom the database by selecting the column and retriving destinct values. I have a function that fires when one of the dropdown lists are changed witch changes the sql datasource select value so it retrives items sorted by the selected categories and locations.
Here is the function:
    protected void DropDownList_Change(object sender, EventArgs e)    {        string Category = DropDownListKategori.SelectedValue.ToString();        string Location = DropDownListEtabl.SelectedValue.ToString();        SqlDataSource1.SelectCommand = "SELECT ARTNR, ARTTYP, AKTIVITET, DATUM, KUND, PLATS, KOMMENTAR FROM ARTIKEL WHERE ARTTYP = @ARTTYP AND PLATS = @PLATS";        SqlDataSource1.SelectParameters.Clear();        SqlDataSource1.SelectParameters.Add(@"ARTTYP", Category);        SqlDataSource1.SelectParameters.Add(@"PLATS", Location);        SqlDataSource1.DataBind();    }
The dropdown lists have an option to not retrive values by category or location. I have set that value to PLATS and ARTTYP thinking the query would would retrive everything if these were selected
SELECT ARTNR, ARTTYP, AKTIVITET, DATUM, KUND, PLATS, KOMMENTAR FROM ARTIKEL WHERE ARTTYP = ARTTYP AND PLATS = PLATS
however if both these drop down lists are set to not filter, my query gets nothing in return. And if one of the lists has this selected and ther other one has a value, say a location or something nothing is retrived either. However if both columns have something selected i do get values returned.
My speculation is that the query beeing run when this happens is that it is trying to find columns having the value ARTTYP or PLATS (category or location), as a string and actually seeing it as Im trying to retrive values where column = column.
Any suggestions on how i can make my query run as intended or is there another problem Im not seeing.
