TableX
-------
X1
X2
X3
TableY
-------
Y1
Y2
Y3
I need to write a query with the following joins:
TableX.X1 = TableY.Y1
TableX.X2 = TableY.Y2
What is the proper way to do this in SQL? Would it be:
select x.*
from TableX x
join TableY y1 on y1.Y1 = x.X1
join TableY y2 on y2.Y2 = x.X2
Is there a more proper way to do this without creating multiple aliases of the same table?
Does anyone know of a neat way of aliasing tables in MS SQL Server 2000? I have a table [X] and I want to refer to it (in TSQL statements, stored procedures, etc.) by two names, say [X] and [Y]. There should be only one copy of the table's data.
I could handle this in my site logic (ie convert [Y] to [X]), but it would be really clean to handle this in the database.
Thanks for your advice.

I need to create a table from these 2 tables and want all the data. Table 1 has 15000 records and table has around 1000 records.
I have 2 tables.
SELECT [UniqueID]
,[Company]
,[CustID]
,[CustomerName]
,[FiscYr]
[Code] ....
i have below queries each select is fetching records at one level. Is there a way i can write single query to get to nth level (recursion) instead joining same table 10 times (i don't know in some cases there is may be next level) I stopped at 10th level now. In below example i gave only two levels.
SELECT Distinct
a.Col1 AS EmpID,
a.Col1 AS EmpID,
a.Col2 AS Emp_guid,
a.Col2 AS Emp_guid,
case
[code].....
I know how to check for a sinle vlaue but how do I chekc to see if multiple values exist. I need to check for certain email addresses from a list that I have.
Let us say I ahve 3 email addresses, I want to check for all of them in a table and for eevery email address that is present I want to print something like "You email address is XXX" and if one of those 3 is not found my results should look like
"You email address is XXX"
YYYYY not found
"You email address is ZZZZ"
I'm attaching some TSQL that I tried on [AdventureWorks2012].[Person].[EmailAddress]
/****** Select ALL if where an email address is present in the list ******/
SELECT EmailAddressID,EmailAddress
FROM [AdventureWorks2012].[Person].[EmailAddress]
WHERE EmailAddress IN
(
'ken0@adventure-works.com', --1
'terri0@adventure-works.com', --2
[Code] ....
-- Test to see if a single email address is present
IF EXISTS
(
SELECT EmailAddress FROM [AdventureWorks2012].[Person].[EmailAddress]
WHERE EmailAddress IN ('25rob0@adventure-works.com')
)
BEGIN
SELECT 'Email address is presnt'
[Code] ....
When I check multiples using EXISTS it works as per its design and says YES even if a single item is present.
I am trying to pivot table DYNAMICALLY but couldn't get the desired result .
Here is the code to create a table
create table Report
(
deck char(3),
Jib_in float,
rev int,
rev_insight int,
jib_out float,
[Code] .....
Code written so far. this pivots the column deck and jib_in into rows but thats it only TWO ROWS i.e the one i put inside aggregate function under PIVOT function and one i put inside QUOTENAME()
DECLARE @columns NVARCHAR(MAX), @sql NVARCHAR(MAX);
SET @columns = N'';
SELECT @columns += N', p.' + QUOTENAME(deck)
FROM (SELECT p.deck FROM dbo.report AS p
GROUP BY p.deck) AS x;
[Code] ....
I need all the columns to be pivoted and show on the pivoted table. I am very new at dynamic pivot. I tried so many ways to add other columns but no avail!!
I have resulting rows from a query similar to the following:
The data is coming from a single table that contains only one coverage code column and one coverage code date, but the end user wants the two coverage code types and dates combined into a single row. So the SELECT looks something like this:
SELECT
[Employee ID] = emp.employee_id,
[Coverage Code 1] = enr.coverage_code,
[Coverage Date 1] = enr.coverage_date,
[Coverage Code 2] = case when enr.product_type = 'Accident.Accident'
then enr.coverage_code else NULL end,
[Code] ....
I basically want to merge the like Employee ID's together into a single row like the following:
I know I have done this before and it is probably pretty simple.
My xml is in below format:
DECLARE @MyXML XML
SET @MyXML = '<RS>
<R id="6330">
<WF id="71445">
<WFS id="12790"> <fname>John12790</fname> </WFS>
[Code] ....
I need to insert into table with TSQL query:
My output should be similar below:
John12790 12790 71445 6330
Eric 12791 12790 71445 6330
John12793 12793 71446 6331
Eric12794 12794 71446 6331
otherwise i need to write huge c# code to execute such thing..
I am looking a script which allow me add single coilumn to multiple table of my database.
For Example :-
I am having 4 table
1-Emp , 2-Dept , 3-Location , 4-Salary like this I have around 100 of table
Now I want to run below command to add column Rowchecksum in all table where table name start with Archivebbx keywords.
Alter table EMP
Add Rowchecksum varbinary(8000)
Say you have a fact table with a few columns that all reference the same key column in a dimension table, you want to write a view to return the information for those keys?
USE MyTestDB;
GO
SET NOCOUNT ON;
IF OBJECT_ID ('dbo.FactTemp' ,'U') IS NOT NULL
DROP TABLE dbo.FactTemp;
[Code] ....
I'm using very small data at the moment, and the query plan and statistics don't really say which way.
I have a table structure where there are multiple "/" separated values in two columns that I need to parse out into single records.
CREATE TABLE CONFIGNEW(PlanID VARCHAR(100), GroupID VARCHAR(6), SubGroupID VARCHAR(255), AddOnCode VARCHAR(2), ExternalCode VARCHAR(20)
INSERT INTO CONFIGNEW(PlanID, GroupID, SubGroupID, ExternalCode) VALUES('101/201', '000005', 'LAA/OCA/UCA/XCA', '1', 'M231_1)
[Code] .....
The results I am looking to achieve are:
PLanIDGroupIDSubGroupIDAddOnCodeExternalCode
101000005LAA1M231_1
101000005OCA2M231_2
101000005UCA3M231_3

Is there an SQL statement that can be used to accomplish this?
I created a CTE which finds a subset of records from a table
I then ran a SELECT statement against the same table as
SELECT * FROM TABLE
EXCEPT (SELECT * FROM CTE)
Is it possible to add another EXCEPT statement after the CTE EXCEPT statement to cover a condition not incorporated in the CTE definition?
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
I'm fairly new to SQL and am just setting up a Windows 8 app using an Azure SQL server. The issue I have is looking up a part number supersession and getting the latest number. One part number can have multiple supersessions (ie RTC5756 > STC8572 > STC3765 > STC9150 > STC9191 > SFP500160 ).The data I am supplied monthly has both the superseeded items and the supersession information in both columns and is not easy to decipher - for example:
Supersessions Table
----------------------
RTC5756 | STC9191
SFP500160 | STC9191
STC9191 | STC2951
STC3765 | STC9191
STC8572 | STC9191
STC9150 | STC9191
[code]...
The newest part number is kept in a separate table - called "source" - which in this instance is SFP500160. I need access to the latest part number but also to the part's previous numbers, due to the fact that some people may still be stocking them as an old part number and for them to search by. Is there an easy and efficient way of doing both a lookup for the supersessions and a join on the two tables to minimize the queries on the database?
I have created a trigger that is set off every time a new item has been added to TableA.The trigger then inserts 4 rows into TableB that contains two columns (item, task type).
Each row will have the same item, but with a different task type.ie.
TableA.item, 'Planning'
TableA.item, 'Design'
TableA.item, 'Program'
TableA.item, 'Production'
How can I do this with tSQL using a single select statement?
The objective is to identify orders where an order fee has been applied incorrectly. I have multiple orders per customer, my table contains an orderID and a customerID. Currently if the customer places additional orders before the previous orders have been closed/cancelled, then additional fees are being applied.
Let's say I'm comparing order #1 to order #2. I need to identify these rows where the following is true:-
The CustID is the same.
Order #2 has a more recent order date.
Order #2 has a FeeDate Before the CancelledDate of Order #1 (or Order #1 has no cancellation date).
So in the table the orderID:2835692 of CustID: 24643 has a valid order fee. But all the subsequently placed orders have fees which were applied before the first order was cancelled and so I want to update the FeeInvalid column with a 'Y'. The first fee will always be valid.
I think I understand why the code I am trying doesn't achieve the result I want but I can't figure out how to write it correctly. Below is one example of code I've tried and also code to create the table and insert some test data.
update t1
SET FeeInvalid = 'Y'
FROM MockData t1 Join MockData t2 on t1.CustID = t2.CustID
WHERE t1.CustID = t2.CustID
AND t2.OrderDate > t1.OrderDate
AND t2.FeeDate > t1.CancelledDate
CREATE TABLE [dbo].[MockData](
[OrderID] [float] NULL,
[code]....
I concatenate multiple rows from one table in multiple columns like this:
--Create Table
CREATE TABLE [Person].[Person_1](
[BusinessEntityID] [int] NOT NULL,
[PersonType] [nchar](2) NOT NULL,
[FirstName] [varchar](100) NOT NULL,
CONSTRAINT [PK_Person_BusinessEntityID_1] PRIMARY KEY CLUSTERED
[Code] ....
This works very well, but I want to concatenate more rows with different [PersonType]-Values in different columns and I don't like the overhead, of using the same table in every subquery ([Person_1]). Is there a more elegant way to do this, without using a temp table or something else?
I have the following results:
ID, Office1
1, Testing
1, Hello World
What i am trying to do is to get this result:
ID, Office1, Office2
1, Testing, Hello World
how i can accomplish this task.
Please help...

trying to write a query from 2 tables and join them only they share a column name of the same name.I can define both aliases seperatrly but get an error when trying both,
select
case_HDR.case_nbr as "test"
Case_DTL.case_nbr as "test2"
From
Case_HDR, case_dtl
I need to join them also but trying to work in stages.
I have a SELECT query with an alias in it.
The intellisense shows all field except the alias one.
What goes wrong?
I'm in the process of building a site and converting views/tables/queries from an Access database to SQL. I've done this quite a few times, and never had any significant issues I couldn't figure out on my own.
In Enterprise Manager, I've created a view and in the query, I need to create an alias that is similar to below:
SELECT ((monthmult) + ((b2avg*15)-(av2*10)) + (lp1+lp2) + ((b1avg*30)-(av1*20))) as PIndexValue
which is how the formula reads in the Access view.
However, when I got to run the query, SQL strips out all of the parentheses and calculates the value in left to right order:
(monthmult + b2avg*15-av2*10 + lp1+lp2 + b1avg*30-av1*20) as PIndexValue
Which gives me an incorrect value.
Does anyone know why this is happening, or am I just unaware of the right way of doing it?
Thank you,
Derrick
Hi,
I’m working with a really old design migrated to SQL 2005, in which I basically have two tables…
Table 1 contains all the “proper” data, and has columns called: col_1, col_2, col_3
Table 1’s data is something like:
col_1, col_2, col_3
Jack,jack@yahoo.ca,Toronto
Jill,jill@hotmail.com,Montreal
Table 2 contains meta-data for Table 1, specifically, it has two columns: column, meta-data
Table 2’s data is something like:
column,metadata
col_1,name
col_2,email
col_3,city
(Hopefully, my description of the design makes sense….basically; Table 2’s data describes what’s in each column of Table 1).
So, the question, if I want to write a ‘SELECT’ on Table 1, how can I use the data in Table 2 as aliases (or column) headers.
I’m currently going down the path of building dynamic SQL statements in T-SQL….but before I get too far, wanted to vet this idea here (it’s always been a fantastic resource for me)
Thanks in advance!

is it possible to assign a numeric value as a column alias:

Does anyone know how to create SQL Server aliases for Itanium servers?
Alternatively does anyone know how to use SMO to create a SQLAliasCollection for a specific server? I can't seem to find how to get that collection.
I've added aliases that work for 32 bit applications but they don't seem to be used for 64 bit applications.
Formatting question. The query below is failing on the columns with spaces in the name. I've tried brackets and single quotes with no luck. How should this be formatted?

I have been working with SQL for quiet a while but think this perhaps is a very basic question that has always escaped me:
At my work I was exposed to both, MS SQL Server 2000 and Sybase Adaptive Server Anywhere/Sybase SQL Anywhere.
Under Sybase I was able to use aliases in other calculations and filters but i have never been able to do the same with SQL.
Example:
In Sybase I can write this:
Select Price * Units as Cost Cost * SalesTax as TotalTaxFrom Invoice Where TotalTax > 3.5
However if i want to do this in MS SQL 2000 i have to go trough
Select
Price * Units as Cost
Price * Units * SalesTax as TotalTax
From Invoice
Where (Price * Units * SalesTax) > 3.5
In the long run this is costing me a lot of code redundancy, not to mention a debugging nightmare. Is there a way to replicate this alias usage in MS SQL Server?
Just stumbled over the interesting bug -
if you have an SQLExpress server and the "allow remote connection" in SQL Instance is turned ON, it doesn't means that it works if you create some aliases for this instance
If Im trying to connect to SQLExpress via new created alias ('localhost' for example) I got the "SQL Server does not allow remote connections" error. Albeit, connecting to ".SQLExpress" is successful.
I've checked the properties of locahost DB instance in SQL Management Studio - remote connection is allowed.
I've restarted the SQLExpress instance.
There is no SQLServer or other instances on my PC
But it doesn't work
How to fix this and allows to connect to sql instance via aliases?
HI,
I have a view where I want to add Rundate and Prev Month Rundate as computed columns to simplify my joins and calculations.
Rundate will be a select from another table that has a list of rundates for each month like this.
SELECT MAX(fm_dateend)
FROM dbo.tbl_FiscalMonth
WHERE fm_dateend <= getdate()) AS smalldatetime) AS CurrRunDate
Now, I want to add Prev Month Rundate on the basis of CurrRunDate but it does not accept CurrRunDate. The query is like this
SELECT MAX(fm_dateend)
FROM dbo.tbl_FiscalMonth
WHERE fm_dateend < CurrRunDate) AS smalldatetime) AS PrevMonthRunDate
Can anyone help me to work around with the alias as I dont like to put a whole bunch of code inplace of CurrRunDate(Alias).
Thanks,
Shariq
Hi All,
I have this query :
select col1, col2, col3, col4, col5,..... , (select col99 from tab2) as alias1 from tab1 where <condition>
order by
case @sortby
when 'col1' then col1,
when 'col2' then col2,
when 'col3' then col3,
when 'col99' then col99
end
when i execute the above query it gives me the following error message.
Server: Msg 207, Level 16, State 3, Line 1
Invalid column name 'col99'.
Thanks in advance.
Thanvi.
I have a question regarding the nature of virtual sql servers, specificially what protocol is used to communicate to the server when a request is made by a client.
For example, if a scheduled job is run on the virtual sql server, what determines the protocol used (e.g. TCP/IP, named pipes etc.) by SQL Server agent? Is it the client network alias set up on the virtual server?
I am asking because currently the client aliases on some of our virtual sql servers are using named pipes and I think this is causing a problem with our backups.
Thanks,
Adrian.
Can someone please shed some light on what seems to me to be a common requirement.
If I create an alias or linked server to Server1 - say Alias1 - on Server1 and then use that name in a query on Server1, a remote/distributed query is always used (even though we are running on the local server and that overhead is completely unnecessary).
Is SQL Server really not capable of deciding that
select * from Alias1.db1.dbo.table1
and
select * from Server1.db1.dbo.table1
should be optimized and executed exactly the same when Alias1 is Server1, but that it is a distributed query ONLY when Alias1 is really referring to a remote server? I realize that the four part name is not necessary when I am referring to objects on the current server, but I am trying to write code that is server instance independent.
It just seems that if that is not possible, then the only way to create system independent stored procs that can run in dev, staging, and production environments and work with multiple databases on multiple servers is to create all sorts of scripts to regenerate all the procs whenever you move a database between servers?
If SQL Server is even close to the enterprise big iron server that MS now claims it is, it surely needs to support running in dev, staging, and production environments and work with multiple databases on multiple servers?!
I'm really looking for someone to tell me I'm missing something simple, and of course you can do this - but complex workarounds are invited too :-)
This is not something I am investigating as an academic exercise, I am already doing this, but I have to figure out how to do it better because with all these unnecessary distributed queries, performance is horrible.
