Using Alias In Update Statement

Jun 30, 2006

Hi,

I am using MsSql2005 and wondering how to create aliases inside update statements. I need this, for a table variable inside a procedure.

UPDATE @TempTable
SET Field1 = (
SELECT
RealTable.Field2
FROM
RealTable
WHERE
RealTable.Field1 = @TempTable.Field1)
This statement doesn't work because I need to use an alias for @TempTable.

How?

Thanx a lot

Using One Alias For Mutiple Columns In A SELECT Statement

Feb 8, 2006

Hi all,Is this at all possible? In the following query I have mutiple columns in my SELECT statement that each have their own alias. Is it possible that I can use just one Alias for all these columns (such as Address), and if so how is it done?SELECT    RTRIM(ISNULL(ta.house_no_flat, '')) as [Target - Flat No.],         LOWER(RTRIM(ISNULL(ta.building, ''))) as [Target - Building],        LOWER(RTRIM(ISNULL(ta.road_street, ''))) as [Target - Street],        LOWER(RTRIM(ISNULL(ta.district, ''))) as [Target - District],        LOWER(RTRIM(ISNULL(ta.town, ''))) as [Target - Town],         LOWER(RTRIM(ISNULL(ta.county, ''))) as [Target - County],        RTRIM(ISNULL(ta.postcode, '')) as [Target - PostCode]ThanksTryst

Update Stmt With An Table Alias?

Jul 20, 2005

Hi all,I am doing the change from having worked in Oracle for a long time toMS SQL server and am frustrated with a couple of simple SQL stmt's. Orat least they have always been easy.The SQL is pretty straightforward. I am updating a field with a Maxeffective dated row criteria. (PepopleSoft app)update PS_JOB as A set BAS_GROUP_ID = ' 'where EMPL_STATUS in ('D', 'L', 'R', 'S', 'T')and EFFDT = (select max(EFFDT) from PS_JOB where EMPLID = A.EMPLID)This stmt is not working. I am getting an error on the keyword 'as'. Ihave tried:update PS_JOB A set...update PS_JOB from PS_JOB A set...Same result, error on 'A' or error on 'from'.I also tried to add the table alias to the sub query, whichtechnically worked, but with wrong data result.So my question comes down to: How do I use a table alias in an updatestatement in MS SQL server?I worked around this by creating a temp table. But that does notfulfill my curiosity, nor is it an ideal solution.Thanks a lot,-OK

Using A Field Alias For A CASE Statement In A GROUP BY Clause

May 20, 2004

When I created a CASE statement (This is at work, Pat:)) it is about 30-40 lines long. I gave it a name and set the name = to the case statement:

ie,

SELECT fieldname1 =
CASE
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
ELSE thisandthat
END
, fieldname2
, fieldname3
FROM tablename1
GROUP BY CASE
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
WHEN condition THEN 'blah blah'
ELSE thisandthat
END, , fieldname2, fieldname3

etc.


The long CASE statement in my GROUP BY is awkward to me. Is this the only way to do it? I tried using the fieldname1 but it comes back as an invalid field name and asks for the "expression".

Regards,

Dave

SQL Server 2012 :: UPDATE Using Table Alias

Sep 21, 2015

I have some stored procedures that do updates using table aliases, like this:

UPDATE TableAlias
SET ColVal = 1
FROM RealTable AS TableAlias
WHERE TableAlias.ColVal <> 1

This allows me to include joins and stuff in the update (not shown) and make it all more readable for me.

It all works fine, and the SSMS parser says it's fine. But I also have another script which looks at sys.sql_expression_dependencies and sys.objects to find stored procedures with invalid object references (see below), and it's understandably saying that all of the above type stored procedures have invalid references.

SELECT
OBJECT_NAME(DEP.referencing_id) AS referencing_name,
DEP.referenced_entity_name
FROM sys.sql_expression_dependencies AS DEP
WHERE
-- Only validate local references:
(
DEP.referenced_database_name = DB_NAME()

[Code] ....

So I have a couple questions.

1. Is the UPDATE syntax I'm using kosher?
2. Can you recommend any updates to my stored procedure validation script that will better accommodate table aliases like mine?

SQL Server 2012 :: Case Statement - How To Get Values Into Alias Extension

Oct 6, 2014

I have a bit of trouble getting values into one alias field, my code is below. I am trying to get values into the alias extension, Agent_ID is sometimes null, and so is agent_id2, however sometimes they both have values in them, and then only one of the values is every returned. When in the example below only Agent_ID (11111) is ever returned by I want both of them returned.

Agent_ID Agent_ID2
11111 22222
<code>
SELECT DISTINCT
CASE WHEN [AGENT_ID] is not null then AGENT_ID
when agent_id2 is not null then agent_id2 end as extension
FROM [AA_Helper].[dbo].[tblEmpData]

Can Create Alias Server1DBInstance1 On Server3DBInstance3 And Assign Objects To That Alias

Nov 24, 2015

We will be moving 2 different databases (SS2005 & SS2008) to a new SS2014 SQL Server.  Currently our codes looks something like Server1DBInstance1... & Server2DBInstance2... Is it possible to move the objects from these 2 instances to Server3DBInstance3 and then use an alias to reference the objects?  Or does Server3 need to have DBInstance1 & DBIstance2?  Basically, is the alias just for the database or for the instance too?  Can I create an alias "Server1DBInstance1' on Server3DBInstance3 and assign objects to that alias?

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?

Aug 29, 2006

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly.  My problem is that the table I am pulling data from is mainly foreign keys.  So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys.  I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit.  I run the "test query" and everything I need shows up as I want it.  I then go back to the gridview and change the fields which are foreign keys to templates.  When I edit the templates I bind the field that contains the string value of the given foreign key to the template.  This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value.  So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors.  I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode.  I make my changes and then select "update."  When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing.  The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work.  When I remove all of my JOIN's and go back to foreign keys and one table the update works again.  Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People].  My WHERE is based on a control that I use to select a person from a drop down list.  If I run the test query for the update while setting up my data source the query will update the record in the database.  It is when I try to make the update from the gridview that the data is not changed.  If anything is not clear please let me know and I will clarify as much as I can.  This is my first project using ASP and working with databases so I am completely learning as I go.  I took some database courses in college but I have never interacted with them with a web based front end.  Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

SQL Server 2012 :: Create Dynamic Update Statement Based On Return Values In Select Statement

Jan 9, 2015

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".

Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

SQL Server 2012 :: Update Statement With CASE Statement?

Aug 13, 2014

i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause

the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]

i was thinking of doing

Update [tablename]
SET [No] =
CASE
WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa'
ELSE 'Null'
END

What is the best way to script this

Stored Procedure - Update Statement Does Not Seem To Update Straight Away

Jul 30, 2007

Hello,

I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.

I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?

ie:

This currently works...

SET @strSQL = 'UPDATE tblTest SET Archive = 1 WHERE RecID IN (' + @IDList + ')

If the ID is not in the list then I want that column set to 0. How can I do this?

Update Statement ?

Oct 14, 2004

Hi, I'm having trouble writing this update statement and was wondering if anyone could help me out :

My database is sort of set up lilke this:
There are 3 tables: Orders, OrderDetails and Inventory

Orders has a pk called OrderID.
OD has several ProductIDs listed for that OrderID
Inventory has 2 fields, the pk InventoryID(which is the same as
ProductID) and QOH

So OD kinda looks like this:
OrderID ProductID Quantity Cost
192 12 2 $10
192 3 1 $12
192 14 2 $50
193 12 1 $11
.... .
...
...

so what i want to do is take each productID for a specific orderid
and decrement the inventory for it by OD.quantity


This is what I was trying

UPDATE Inventory
Set QOH = QOH - @qty
WHERE Inventory.InventoryID IN (
SELECT ProductID
FROM OrderDetails
WHERE OrderDetails.OrderID = @OrderID
and @qty = OrderDetails.Quantity
)


but, i'm having no luck...... any suggestions ?

Update Statement

Aug 29, 2003

I am looking for a solution to my unique problem.

myTable is having following records

ID Field1 Field2 Field3 Field4
1 x y 100 0
2 xx zz 5 0
3 x y 200 1
4 a b 1 1
5 a b 2 0
6 k L 78 1
7 aa bb 25 1
8 k L 15 0

Now the problem is if I want to update a latest record's(if you go by ID)Field4 with 2 for the records where Field1 + Filed2 is unique, can I do this in a single query?

I can select the unique record by the following query

select Field1,Field2 from myTable group by Field1,Field2 having count(ID)>1

Any ideas?

IF Statement UPDATE

Mar 3, 2008

Hi first post, so apologies if this is in wrong forum.

I am needing to update a field in one table, where a particular value of another table is TRUE, and update that table based on a common field in both tables.

at the moment my query is:

IF EXISTS (SELECT * FROM _tblSnapShotAUSProfServicesOrderLines_Daily
WHERE _tblSnapShotAUSProfServicesOrderLines_Daily.Produc tRelProductName like 'Prof%')
UPDATE OrderHeader_details
SET ServicesSold = 'Y'
WHERE OrderHeader_details.OrderRef = _tblSnapShotAUSProfServicesOrderLines_Daily.OrderR ef

In its current format, I get the column prefix is incorrect which makes sense sort of.
No matter which way I change this, I cannot get the query to work. I one form, it works but essentially performs two seperate statements, one with the select, and one with the update which unfortunately updates every row in the table.

Any assistance is appreciated.

Need Help With A Sql Update Statement

Sep 24, 2007

Hello,

I need help with a sql update statement i need it to convert a datetime value to a specific format. For some reason it statement will only update the row only when i convert the datetime value to a varchar, i ran it in mssql sql server management studio and it works, the database is a mssql 2000 i think. If i try to compare the datetime value and they are both DateTime values it fails, if i convert them to varchar and run them they succeed, what i also noticed is when when are date values are that the value i passed in the query is that they are in a different format, i guess the database stores them as mon/dd/yyyy hh:mm:ss. but when i run the query that failed i get this as the results of the values from variables @Date1 & @Date2: They are the same and they failed. So if anyone knows any thing any help is surely appreciated this really sucks.

Failed
