I have a table product, columns:id,date,product,productname
I want to create a insert trigger, when I insert id,date,product, the productname will auto update in to the table(the product=productname... I don't know how to make the equation, please help me.
sorry for my terrible English.

Why have two columns with the same data?
Have you tried anything at all yet?
|
|
|
|

CREATE TRIGGER (Transact-SQL) | Microsoft Docs[^]
CREATE TRIGGER YourTriggerName
ON YourTableName
AFTER insert, update
As
BEGIN
SET NOCOUNT ON;
If UPDATE(FK)
BEGIN
UPDATE
T
SET
RedundantDuplicateColumn = T2.Name
FROM
YourTable As T
INNER JOIN inserted As I
ON I.PK = T.PK
LEFT JOIN YourOtherTable As T2
ON T2.PK = T.FK
;
END;
END
Replace the dummy table and column names with the real table and column names.
Remember that triggers will fire once per batch, not once per row. There could be multiple rows in the inserted table.
But as CHill60 said, duplicating the product name in both tables seems like a bad design. If you have the ID of the product, you can simply join to the product table to get the name on demand.

This is a REALLY BAD design, instead of having a separate table for productname create a view
create view vwProductName
as
select distinct product as productname from product

Am I missing something ... where's the table for the ProductName mentioned?

So yes I think you missed this.

It's an ERP bill, customer want to input the batch number, but they don't want to use any rules, just want to fetch the bill number into that field.

The comments still stand - there should be no reason to store the productname in a different table especially as it is user input and free form.

Hi,
I have a query that is using FOR XML PATH, when the child elements has values then its giving the Child elements, but when there are no values coming out of query for the Child elements, its finishing the X-path by putting and end tag (\), but I want the all the elements to be created if there are values are not, it doesn't have to repeat the elements as if there are values but at least one occurrence has to be there even if there are values or don't have values.
Below are the example for it.
Case 1 is the file that it is creating with all the values and elements, there are elements that are repeated I am not putting all that xml here to reduce the size, but I want to create all the elements of the xml even if there are values or no values at least one occurrence.
<TB_BILLING_PROVIDER_FILES>
<TB_TRADING_PARTNER>
<Owner>DMH</Owner>
<TP_EIN>9xxxxxxx1</TP_EIN>
<TP_NAME>Alameda</TP_NAME>
<County_Code>01</County_Code>
<TB_BILLING_PROVIDER_FILE>
<TB_SERVICE_FACILITY>
<Service_Facility_NPI>xxxxxxxx7</Service_Facility_NPI>

<Taxonomy_Code/>
</Service>
</TB_SERVICE_FACILITY>
</TB_BILLING_PROVIDER_FILE>
</TB_TRADING_PARTNER>

The Case 2 xml is as below:
<TB_BILLING_PROVIDER_FILES>
<TB_TRADING_PARTNER>
<Owner>DMH</Owner>
<TP_EIN>xxxxxxxxx</TP_EIN>

Last tuesday I made a suggestion to you that would probably help you get assistance.
CHill60 wrote: You might get a better response with some sample data and expected results
You've given us the outputs but still haven't provided any sample data ... on the tables (or views) vw_ServicesXML5010, vq_ServiceFacilityXML5010, vw_OwnerXML5010 or dbo.vw_SDMCPhaseTwoParentLevelXML
You have said that you don't understand how the two scripts are different, yet one of them is reading from vw_OwnerXML5010 but the other is reading from dbo.vw_SDMCPhaseTwoParentLevelXML having been given an alias of vw_OwnerXML5010. I suggest you start by comparing the output of the following sql commands
SELECT * FROM vb_OwnerXML5010 and
SELECT * FROM dbo.vw_SDMCPhaseTwoParentLevelXML introducing an appropriate WHERE clause to both.
We can't help you any further without sample data.

I am having a query on the Production Server, I am getting an xml out of it. For some reason there is a problem in the data that I am getting, some data is missing, but I can't easily compare and see it on the xml file what am I missing and why.
It would be easier for me if I put the same Data into Table then I can easily compare what am I missing. Or is there anyway that I can read the Data from xml file and put it into a table? I am trying but I have to create table before it seems, but I want to just import into Table like we do from excel files.
Thanks,
Abdul Aleem

Are you are expecting us to guess what that error might be?
There are plenty of people who would like to help you solve your problem, but you're not giving us much to go on. We do this in our spare time so expecting us to wade through the SQL to try and create some tables to match it so we can see what is being produced so we can work out how to replace the FOR XML and get appropriate results ... would take more time than most of us have available.

I can understand by can you please help me how can I create dummy values for the views vw_ServicesXML5010, vw_ServiceFacilityXML5010, as those views are not fetching any records, the xml is not generating those elements, is it possible to help me in that regards.
For example if I don't have any records for the View vw_ServicesXML5010 for that where condition I want to have empty value for the elements Procedure_Code, Modifier1, Modifier2, Modifier3, Modifier4, From_Date, To_Date, Revenue_Code, Place_Of_Service, Taxonomy_Code
Same thing applies to the View: vw_ServiceFacilityXML5010, if it doesn't have any records then at least one record set with empty values for the Service_Facility_NPI, County_Owned_Indicator.
Can you please help me buddy, thanks in advance.

I just got a requirement for a web API to an Oracle database. So I fire up an Oracle DAL from 2010 only to find the reference to System.Data.OracleClient are out of date and it is not recommended. Searching for Oracle Connection does not uncover the references required, connection strings.com was no real help.
Can someone advise me on the current references for VS 2015 to connect to Oracle please. I can't add object to the server as one article suggested just a plain read only connection is required.
[edit0]
Looks like this is the latest tool from Oracle Oracle Data Provider for .NET (ODP.NET)[^]. What a PITA,
First I need an account to download, create an account, nope email already has an account, do the forgot password thing. Ok have account not to refind the link to download.
It has to be run as admin if you want to install for all users, you are not given a choice to install for just yourself. Have to close all VS Instances. I'm betting the 2017 version does not work with 2015 and it seems like you can only have 1 version installed. 
As I sit here waiting for help desk to allow me to install a .net driver I really do not like Oracle.

In my experience, System.Data.OracleClient should actually work just fine, it was even getting updated with new functionality for VS2015. BUT, it might break if your Oracle DB gets updated.
Otherwise I strongly recommend to get the managed version of the driver.
It doesn't need installation and it's not sensitive to 32 or 64 bit versions, just paste the dll into the bin folder and add a few lines into the app.config.
Example below. You obviously need to correct for your version of the client.
<configSections>
<remove name="oracle.manageddataaccess.client"/>
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342"/>
</configSections>
<system.data>

<remove invariant="Oracle.ManagedDataAccess.Client"/>
<add name="ODP.NET, Managed Driver" invariant="Oracle.ManagedDataAccess.Client" description="Oracle Data Provider for .NET, Managed Driver" type="Oracle.ManagedDataAccess.Client.OracleClientFactory, Oracle.ManagedDataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342"/>
</DbProviderFactories>
</system.data>
<oracle.manageddataaccess.client>
<version number="*">
<dataSources>
<dataSource alias="ORCL" descriptor="
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = my.address.net)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
)
)
"/>
</dataSources>
</version>
</oracle.manageddataaccess.client>
<connectionStrings>
<add name="IDB" connectionString="user id=MyUser;data source=orcl;password=MyPassword;Enlist=false" providerName="Oracle.ManagedDataAccess.Client" />
</connectionStrings>configSections NEEDS to be FIRST in the configfile.

For having been deprecated for so many years (2009), it's getting an awful lot of updates.

The content of the tnsnames.ora can be put in so many different places...
Happy it works for you. Configuration of Oracle is admittedly a PITA.

Hello,
I have two SQL 2016 Always On nodes - (VMware Virtual Machines). Each node has 250GB RAM, 46 vCPU @2.5GHz. Each of the MS SQL VM is dedicated to 1 ESXi Host so there is no resource contention.
The application that would connect to the Database is expected to be: 70% WRITE and 30% READ.
I need advise on the best way to:
(1.) Configure MS SQL nodes to use the 250GB RAM, 46 vCPU efficiently and optimally.
(2.) Perform Write and Read as fast as possible using all the hardware resources.
(3.) I have configured Always On Read Routing, how can I test it?
Thanks.

"As fast as possible" will take some experimenting and reading, will depend on your data-structure, indexes, triggers, and a bunch more - a bit much for a single forum-post.

Hi friends,
Its easy, create a Boolean or some other type variable, assign that value accordingly in the script task, then after the script task, you can have more than one Precedence Constraint Editor, in that, take the Evaluation Operation as either expression or expression and Constraint etc according to your needs then set the expression with your variable that you have assigned in the script task, now after the script task it will either continue with next steps or it will go to the task you have assigned after the failure constraint.
This is all it is, thank you SSIS and thanks for all the friends who tried to help or support me.
Thanks,
Abdul Aleem
