Querying Two Tables
May 23, 2008
This is my problem
Table A Columns:
OriginatingNumber,
TerminatingNumber
Both of these columns contain npanxx numbers which would be the first 6 digits of a phone number, example 217345 which is in illinois.
Table B Columns:
npanxx,
state
table B hold all npanxx numbers in the united states and what state it pertains to.
what i need to do is run a query to check and see what state the OriginatingNumber and the TerminatingNumber are in and decide if both numbers passed are in the same state or not.
so for example in Table A Row 1: OriginatingNumber is 217345 and the TerminatingNumber is 309454. I need to check both of these numbers against table B and it would return that both numbers are in IL. Basically I need to return a result of yes or no. yes they are in the same state or no they are not in the same state.
Any help would be great
Thanks for reading,
Nick

Hi all,
How do I query two tables in different databases on the same SQL Server?
In short, I want to do:
Select A.*
from database 1. table 1 as A
inner join database 2. table 1 as B
on A.COL1 = B.COL1
Both database 1 and 2 are on the same SQL Server.
Please advise.
Thanks,
V

Hi, while I'm trying to do Select statements, is there a way/setting whereby I don't have to constantly prefix the table names with a prefix?
For example, I'm working in multiple environments and they're differentiated by the prefix in their table names, uat.** vs prod.**
Any help would be appreciated.
Please email me at dickson.lau@rogers.com
Thanks again.
Dickson

I get a 90-120 second blocking when send 15 or so simultaneous queriesto SQL Server 2000 that query a view made up of two joined tables.After each query is blocking for the same amount of time they allreturn. Further identical queries of this type work in 3-4 seconds(caching?) until hours later where it happens again. If I query thetables directly (without the view) I still get the same blocking. If Iremove the join (it is a simple inner join on two columns) I do not getthe blocking.Any ideas?

This seems like a very simple question but i have never been able tofind an easy answer to it.I have a user table and i do a join with another table, we'll call theother table a results table.The results table has numerous rows with the userid foreign key.I want to make a query that will give me the number of rows in theresults table for each user where the result is some valueThe query is simple to make but will only show the users who have arecord in the results table the meet the where criteria, however i wantto display each user and show a record count of 0 when there are noresults in the results table that match the criteria.for example i have 2 tables.tblUsers_______________userid | username--------------------------1 | user12 | user2tblAnswers________________userid | answer----------------------------1 | 11 | 01 | 42 | 12 | 0if i run the query:select max(username), count(answer) from tblUsersleft outer join tblanswers on tblAnswers.userid = tblUSers.idwhere tblAnswers.answer = 4group by tblUsers.idi just getuser1 | 1i want to getuser1 | 1user2 | 0the only way ive found to do this is with a temp table and a curser tocreate all the users records and go back through an insert the answercount for each user. This approach seems very expensive and requires aquery that is 3 times larger than is needed for the same resultswithout including 0 count records. I know there must be a better way todo this.Any help is appreciated.

Hi all,
I'm using SQL Server 2005 Express Edition, and I have restored a database that was using SQL Server 2000 previous. All of that went fine - sprocs and tables/data all made it.
However, when viewing the tables in the object explorer in the management studio, all the tables are prefixed with the schema name (testuser - so the table names are like: testuser.pn_user). Now, all of the code I have queries the tablename only without prefixing testuser to it - but this doesn't work anymore (invalid object name.)
I've tested, and if I prefix the table names in my code with "testuser.", it starts working again, but would rather avoid doing this. Is there something I can do within Sql Server? I've made the "testuser" account "mapped" to the database I'm using (not sure what that means - I'm more of a software developer than a database guy.) Also, when I do "Properties" for the "testuser," the default database is set to the one I'm trying to query w/o the schema.
Any ideas?

I am trying to query multiple tables that have the same column. They are a supposed to be a unique ID to the product, but not to the database. I have a primary key already set to each othe tables. The tables do not share anything between them, but i would like to search for these IDs in other tables before my insert command is executed. I am writing my code in VB. example of what i am trying to accomplish.
Table1 = TVs
ID/SKU_ID/Manufacturer
1 87654 Samsung
Table2 = DVD_Players
ID/SKU_ID/Manufacturer
2 765234 Kenwood
I want to search for SKU_ID in multiple tables( I think a total of 9 tables). I want to search between tables to catch for the same SKU_IDs. and if it finds it, raise error. I will be able to figure the vb.net portion. I just dont know how to go about the sql query portion. Thanks in advance and appreciate any help. Thanks!

What I am trying to do now is combine multiple complex queries into one table
and query it showing the results on an ASP.net page.
I am currently using SQL Server 2000 backend. Each one of these queries are
pretty complex so I created each query as a Stored Procedure. These queries are
dynamic by each user, so the results will never be the same globally.
What I have done so far was created a master stored procedure passing the
current user's username as a parameter. Within the master SP (Stored Procedure)
it creates a temporary table inserts and executes multiple stored procedures and
inserts into the temporary directory. Each of the sub stored procedures all
have the same columns. After the insert to the temp tables, I then query the
temp table and return it to the function it was executed in code and fill it as
a System.Data.DataTable. I then bind the DataTable to a
Repeater.DataSource.
Problem: When the page is rendered, it returns nothing. I
tested the master SP in the data environment and it works fine.
Suspect: ASP.net when the SP is executed, it sees that the
data is a disconnected datasource? Perhaps the session in the SQL Server when
the temp table is created isn't in SYSOBJECTS system table?
Here is an example of the code from the master SP:
CREATE PROCEDURE dbo.TM_getAlerts @Username
varchar(32)ASCREATE TABLE #MyAlerts ([DATE] datetime, [TEXT]
varchar(200), [LINK] varchar(200) )
INSERT INTO #MyAlertsEXEC
TM_getAlertsNewTasks @Username
INSERT INTO #MyAlertsEXEC
TM_getAlertsLateTasks @Username
SELECT [DATE] AS 'DATE', [TEXT]
AS 'TEXT', [LINK] AS LINK FROM #MyAlerts
GO
It is a fairly simple call... but why doesn't ASP.net doesn't see it when the
the DataTable is filled. I tried just executing one of the sub SP without
creating temporary tables and it works flawlessly. But the query in one of the
sub SP is a normal but complex select.

I think this should be a dead easy one.
SQL Server 200.
Can I query to find all the tables in a single schema? I can't for the life of me find this one out!
I'm currently using a dreaded cursor with an exists test to get the results I want but there is surely an easier way!
Cheers,

Hi, all:This is probably a simple problem, but, as an SQL newbie, I'm having alittle trouble understanding multi-joins and subqueries.I have the following tables and columns:MemberTable-----MemberID (primary key)MemberNameAddressCountryFoodsTable------FoodID (primary key)FoodNameMusicTable-----MusicID (primary key)MusicNameMoviesTable-----MoviesID (primary key)MoviesName....and their linking tables...Members2FoodsTable-----MemberID (foreign key)FoodsID (foreign key)Members2MoviesTable-----MemberID (foreign key)MoviesID (foreign key)....and so forth.Now what I'm trying to do is retrieve a specific MemberID, his address info(from the Members table), and get a listing of his favorite Movies, Foods,Music, etc. I know I probably need to JOIN tables, but where do I JOIN thetables? Do I have to JOIN the various Music/Foods/Movies tables or is itthe Music/Members2Music and Foods/Members2Foods, etc. tables? And I assumeI would probably need to perform a subquery somewhere?I realize I'll need to first filter the Members, Members2Music,Members2Foods, etc. tables by the MemberID, and afterwards, retrieve alisting of the actual Music/Foods/Movies names. I'm just confused how to dothat. (By the way, I have a total of 10 other tables or in addition toMusic, Foods, etc. so it's a lot of table JOINing.)If someone could please help me out with the actual SQL coding, I'd reallyappreciate it!Thanks for the help!J

I am learning T SQL and SQL queries and have limited VB knowledge, and have a some simple queries to run on a table with parameters, and would like verification of the proposed methodology and suggestions.
Simply put, I have a [Transactions] table with columns [Price], [Ticker], [TransDate], [TransType] and calculated columns for [Days] and [Profit].
There are two parameters, [@Dys] (to query a the table for transactions within a certain period[Days = 30] and [@TT] to query only the closed transactions ie... [TransType='C']
I have been studying Stored Procedures and will be writing a Stored Procedure, but need verification if the following will work... Getting the SUM and AVG calcluations for the fields above is not a problem but I need to display SUM and AVG information also for those transactions where [Profit >0] and [Profit <0], which is easy enough by creating a subquery. But the problem is:
1. If I use a SubQuery for [Profit <0] and for [Profit>0], can I create an alias for [Count(*)] (to get a row or transaction count for each, and then divide that into the Total [Count(*)] alias for the Transactions table to get a value for % profitable or Probability (% total Profitable trades versus % total Unprofitable trades)?
2. Or, do I need to create either temporary tables or views to have 3 distinct tables (1 table for Transactoins and 2 temp or Views for [Profit >0] and [Profit <0])?
Any suggestions and advice or examples on how to do this would be appreciated.

I need help in writing a query.
The query should get top 10 items and their values from current year and the values for the same items from previous year table.
I was able to write the code for 1st part that gets values from 1st table but I don't know how to get the values from 2nd table.
The 2 tables does not have any primary/foreign key relations. Both tables have same structure and same columns.
I am attaching some images below to give more information.
Image of results from my query.
Image of how the final output should look like.
The Store Procedure code is:
ALTER Procedure [dbo].[free_customsHS4](
@TblName1 varchar(20),
@TblType varchar(20),
@District varchar(6),
@Month varchar(3)
)
AS
Begin
SET NOCOUNT ON;
Declare @SQuery nvarchar(3000)
set @TblName1 = '[' + @TblName1 + ']'
set @TblType = '[' + @TblType + ']'
SELECT @SQuery = 'select top 10 a.commodity1 as HS4, b.descrip_1 as Description,
sum(a.all_val_mo) as [Amount],
(sum(a.all_val_mo)/(select Sum(a.all_val_mo) FROM ' + @TblName1 + 'a
where a.stat_month <=' + @Month + ' and a.district=' + @District +'))*100 as [% Share]
FROM ' + @TblName1 + ' a left outer join ' + @TblType + ' b on a.commodity1=b.commodity1

Dear Readers,Is it possible, like in Access, to link to tables in other SQL databases that are on the same server? I have a query that I originally had in Access that queered from multiply databases. It did this by having those other tables in the other databases linked to the database that had the query.

I'm a newbie to SQL and wanted to see if someone could help me write a query. I store historical options data in a SQL data base and I'm trying to create a query that will retrieve all ATM (at the money options).
For each unique stock symbol (STOCK_SYMBOL) in my database find the strike price (STRIKE) which is closest to the stock price (UND_LAST). This will be refined by the EXPIRATION and OPT_TYPE
The following query returns all options not just ATM options.
SELECT STOCK_SYMBOL, UND_LAST, STRIKE, EXPIRATION FROM DATA
WHERE EXPIRATION > '2007-02-01 00:00:00'
AND EXPIRATION < '2007-02-28 00:00:00'
AND OPT_TYPE = 'CALL'
Related DB fields.
STOCK_SYMBOL
STRIKE
UND_LAST
OPT_TYPE
EXPIRATION

I am using MS SQL Server 2005 Import and Export Wizard (.net framework Data Provider for mySAP Business Suite. )
as a interface between SAP and MS SQL 2005.
Once the connection is created i can use basic query to fetch the data from SAP tables
ie., SELECT * FROM AFPO
But say I want to EXTRACT data just for month of July from AFPO.
AFPO does not have date field so you have to join AFPO to AUFK and AUFK to COEP to fetch the date as a criteria to restrict data for the month of July .
This can be done in ABAP by view or Interim Table, if you have Developer Key.
Can anyone please tell me if aforesaid is possible with MS SQL Server 2005 Import and Export Wizard query ?

Hello,
I want to find all the entries where the date field is a specific date; so I may have 5 entries with the date 1/1/2006, and I want to find all of those. However, datetime fields in SQL Server also have the time, so how do you handle that? Can you just say where requestdate = getdate() to get all of the entries that have records for today?
How does time affect this?

If you create a view such as CREATE VIEW TestView AS Select * FROM customers_table WHERE CustomerID between 213 AND 3443 Each time you want to select from the view - is the View going to perform the WHERE clause on the customers_table, or not? Or does the view already have the virtual rows?, meaning it does not have to perform a where clause (WHERE CustomerID between 213 AND 3443) on the customers_table, and just performs an inner join with the rows it already has?

I have a table containing prices. This table will be queried very often to provide quotes for clients.So to ease the burden on the server I want to cache the table and then just query the cached version.However it seems that I can only cache the table as a datatable. This means I have to query the datatable to get the prices for each quote.I'm not sure how to query a datatable. Is ther syntax similar to querying a SQL table?In fact is this best way to go about things?Any help would be appreciated.G

Hi guys
im struggling to see what im doing wrong with the following SQL, wondering if it has something to do with the subquery being a view...cant think why though
select value from table
where type = 'Extra Mailbox'
and active = 1
and value not in
(select login from view)
order value
The view returns a list of logins and the type field is also a list of logins. I want to filter the list of logins that do not appear in the subquery....
Any ideas?
Thanks in advance for any responses.

Hi All
Thx in advanced for any help anyone can offer me.
I have 2 tables Staff and Class which are as follows
Staff
ID (Primary Key)
FirstName
MiddleName
Surname
Etc. . .
Class
ID (Primary key)
LessonTemplateID
TeacherID
TermID
AssistantID
LessonTemplateID and TermID link to other tables which i don't need right now.
The Class.TeacherID and Class.AssistantID both link to the Staff.ID
I am trying to create a query where i can say i want to select a class.ID of lets say 12 and display both the Teachers name and the Assistants Name.
If i do just one join between Staff.ID and lets say Class.TeacherID all is fine and i can display the teacher.FirstName for a particular class.ID. However my problem is when im trying to display both teacher and assistant. Every time i try to create a query to do this the query comes back blank.
Im really stuck on this and just can't figure it out (is it even possible?).
Thx for any help Scott.

Hi All,
I am very new to sql and I am not really sure of what I am doing.
I have a bit of a complicated stored procedure that I am trying out. There is 3 parts to it to search for new articles,updates and discontinued articles for a particular Supplier. Right now I am just trying to get the first part working - I am trying to query another database that has 4 tables, 2 are joined ActiveArticle & ActiveArticlePrice and the other 2 are also joined UpdateArticle & UpdateArticlePrice. But all tables also hold data for ALL Suppliers, they are recognised by a GUID - SupplierGuid.
I want to compare them to each other to see if there are any new articles added to the Update tables. This is what I have so far, I was hoping someone could tell me if they see some obvious mistakes(I'm sure theres many!). For the first select, I tried adding a couple of parameters Flag and Text to use so that I can order it all once i have the 3 parts working. But I don't know the syntax is right, because then I also want to select all fields in both tables?.
CREATE PROCEDURE Portal_GetPriceListUpdates
(
@SupplierGUID uniqueidentifier
)
AS
SELECT 'A' AS FLAG, 'New Product' AS TEXT, * FROM SupplierUnits.UpdateArticle UA, SupplierUnits.UpdateArticlePrice UAP WHERE EXISTS
(SELECT * FROM UA, UAP WHERE UA.SupplierGuid=@SupplierGUID AND UA.SupplierArticleNumber NOT IN (SELECT SupplierArticleNumber FROM SupplierUnits.ActiveArticle.SupplierArticleNumber))
GO
I would appreciate any help!
Thanks,
pp
