Transact SQL :: Referencing More Than One Table

Jul 22, 2015

I have a very simple bit of code.


[Code] ....

My issue is I want to run this bit of code but only if dbo_MF_PATIENT.MFPatientID appears in any of the 3 tables below:


Suppose im unsure on the joining because there is only ever one patient in the

dbo_MF_PATIENT table but they could appear dozens of times in any of the other 3 tables.

Transact SQL :: Update Multiple Table Referencing New Table Data

Aug 4, 2015

I have a table called ADSCHL which contains the school_code as Primary key and other two table as

RGDEGR(common field as SCHOOl_code) and RGENRl( Original_school_code) which are refrencing the ADSCHL. if a school_code will be updated both the table RGDEGR (school_code) and RGERNL ( original_schoolcode) has to be updated as well. I have been provided a new data that i have imported to SQL server using SSIS with table name as TESTCEP which has a column name school_code. I have been assigned a task to update the old school_code vale ( ADSCHL) with new school_code ( TESTCEP) and make sure the changes happen across all 3 tables.

I tried using Merge Update function not sure if this is going to work.

Update dbo.ADSCHL

Transact SQL :: Referencing UDFs And Sprocs In Linked Server

Oct 7, 2015

We have migrated a database (myDb2014) to a SQL Server 2014 instance. We have another on a 2008R2 instance (myDb2008). Both on the same server.

I have setup a linked server to the 2014 instance from the 2008R2 one.

I have a number of sprocs on myDb2008 that call TVFs and sprocs on myDb2014. This worked fine when they were both on the same instance.

Now however, I have an issue where I would have to update all the references in each calling query.

I looked into creating Synonyms but this only works for Tables/Views.

Is there a workaround to querying myDb2014 TVFs/sprocs without having to update each calling query in myDb2008?

Mind Boggling / How Can You Query Self Referencing Tables? (self Referencing Foreign Keys)

Jun 15, 2006

For example, the table below, has a foreign key (ManagerId) that points to EmployeeId (primary key) of the same table.
-------Employees table--------
EmployeeID  . . . . . . . .  .  .  int
Name  .  .  .  .  .  .  .  .  .  .  .  nvarchar(50)
ManagerID  . . . . . . . .  .  .  .  int
If someone gave you an ID of a manager, and asked you to get him all employee names who directly or indirectly report to this manager.
How can that be achieved?

Delete Rows In One Table By Referencing Another Table Info

Sep 16, 2004

I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.

Here is a basic breakdown of what I am trying to do:

Table1 (the table where the rows need to be deleted from)
Column_x (Holds the id that is unique to the various rows of data - User ID)

Table2 (Holds the user information & has the associated ID)
Column_z (holds the User ID)

I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.


SELECT Column_z
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z <> Column_x

This did not seem to do what I needed, it did not delete any rows at all.

I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2

Then I tried another scenerio that I also needed to do:


SELECT Column_z, Column_a
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z = Column_x AND Column_a='0'

'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.

Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.

Any ideas on what I am doing wrong here?

Self-referencing Table

Sep 1, 2007


I'm using MS SQL 2005 Express.

folderName varchar(50) NOT NULL,
parentFolderID int NULL

if I add an ON DELETE CASCADE to the foreign key, then i get an error... which is annoying. If a folder is deleted, then all its sub-folders should also be automatically deleted.

The error is: 'Introducing FOREIGN KEY constraint 'FK__Folder__parentFo__7D78A4E7' on table 'Folder' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.'

Anyone got any advice?

Using Employee/Boss Self Referencing Table

Feb 28, 2008

I have an Employee table that has
EmployeeID (PK)
SupervisorID (which is really just another EmployeeID)
..random junk...

Now that part makes sense, everyone gets one and only one boss.

Their boss can change, and therefore the SupervisorID would be updated.

Now I have an EmployeeEvals table that has quarterly evaluation data.

I want to relate these two tables.

Eval table has
EvalID (PK)
ReviewedEmployeeID (the one being evaluated)
SupervisorID (the one doing the evaluation)

Now I need to link this back to the employee table (at least I think I do).

So I would want to relate it by the ReviewedEmployeeID going back to EmployeeID in the employee table and I also want the SupervisorID to do the same...

But of course that won't work because that would seem to indicate that a single record on the Employees table (say EmployeeID 55) should have a matching (or could) record in the Eval table that would look like
EvalID: 12345
ReviewedEmployeeID: 55
SupervisorID: 55

which of course wouldn't happen as an employee wouldn't evaluate themself.

How do I handle the relationships for this properly?

Do I just not link the SupervisorID back to anything?

Referencing A Users Table For History

May 6, 2008

I've recently finished an application for a small company with perhaps two hundred employees. Each employee was set up in a Users table in the database, against which application logins were processed.

For just about every other table in the database, other than pure lookup tables, we created columns to indicate the user who created the entry, and the user who last modified the entry. This was done using FK references back to the Users table. Each table contains two references back to the Users table, and there are over 150 tables now that follow this scheme. At first I was not concerned, other than the fact that it makes a visual picture of the data model look very confusing (almost every table has a pair of links back to the Users table), until I encountered an issue where I could no longer delete from the Users table. Upon surpassing 253 FK references to Users, I can no longer delete users, as the Query Optimizer can't complete the query.

Now, all of that so far is really not a big deal. Deleting users was never my intent anyway. The only real question I have is whether this is the standard way of maintaining history for table records. Have others used this method? Is there a better way?

Instead Of Update Trigger W/ Self-Referencing Table

May 1, 2006

Using SQL 2005


ID Name RefID
1 Test1 <NULL>
2 Test1a 1
3 Test1b 1
4 Test1b1 3
5 Test1b1a 4



SET ID = @new_ID
WHERE ID = @old_ID

SET RefID = @new_ID
WHERE RefID = @old_ID


RefID is the FK to ID
ID is also the PK to another table and has the relationship use cascading Delete and Update.

"The UPDATE statement conflicted with the SAME TABLE REFERENCE constraint"
This is referring to the first UPDATE of the Trigger.
It was my understanding that Instead Of checks the constraints after it is all done yet it errs with the first Trigger UPDATE.
I was expecting to overcome the self-reference constraint issue by using Instead Of and with the first Trigger UPDATE, change the ID(PK) and then change the RefID(FK) with the second Trigger UPDATE.
Once that was done, it should have not had any constraint problems. Thoughts?

Thanks, Nathan

T-SQL (SS2K8) :: Inserting Into A Self-referencing Table Using Identity Int

Jul 14, 2014

We are in the conversion process of making the database ints.This is a change from a guid PK to an integer based PK that uses an int Identity. The program still uses the guid, and we are trying to map that guid to the databases int.We insert using TVPs passed from code. Since the identity is being set upon insert I have three things to accomplish:

1) Insert all the data into the dbo table
2) Update the parent Id in the table
3) Pass the SetsId guid, Sets_Id int, ParentSets_Id int back to the program

This is a high transaction table that will have a lot of records (millions).

--Sample table creation. There is a FK between Sets_Id to ParentSets_Id, Clustered PK on the Sets_Id
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[JSets]') AND type in (N'U'))
CREATE TABLE [dbo].[JSets](

Hi everybody, 
I know that it is possible for one column to reference two different parent tables by defining two foreign keys on a same column, I have done it and SQL Server does give any error. But I want to know that is it advisable to define multiple foreign key on a column referncing two differnt parent table's primary key in differnt case... ? Means If Case 1 then It should reference to column1 or table1 otherwise it should reference to table2? How is it practicle...?

SQL Server 2012 :: Building Self-referencing Hierarchical Table

May 21, 2014

An example of what I am talking about is the employee table in the Adventureworks database. This has employeeID and then ManagerID, ManagerID just being the EmployeeID of the person whom the original reports to.

I know the queries for querying this type of data and even making recursive common table expressions. What I cannot seem to find is how one goes about BUILDING said table. I see all sorts of examples where people are just doing INSERT table VALUES () manually to load the table. The problem is, I need to create a table that has potentially thousands of records.

It will essentially be a dimensional map. Don't even get me started as to they why, I will just suffice to say that is what the client and project want . I have a process that will do this now, but it is not very dynamic and very hard coded. To me, there seems like there should be some sort of standardized methodology for handling this.

Problem Referencing A Column In A Table Variable In A Query.

Apr 23, 2006

Hello All

I have the following problem running an sp with a table variable (sql server 2000) - the error which occurs at the end of the query is: "must declare the variable @THeader" . @THeader is the name of the variable table and the error occurs with such references as @THeader.ApplyAmt, @THeader.TransactionHeaderID, etc.

declare @THeader TABLE (
TransactionHeaderID [int] NOT NULL ,
PatientID [int] NOT NULL ,
TransactionAllocationAmount [money] NOT NULL ,
ApplyAmt [money] NULL ) - create table variable

insert into @THeader select TransactionHeaderID,PatientID,TransactionAllocationAmount,ApplyAmt from mtblTransactionHeader where PatientID = 9 - fill the table variable

set TransactionAllocationAmount =
(SELECT isnull(Sum(mtblTransactionAllocation.Amount),0)
FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID or
mtblTransactionAllocation.CRID = TransactionHeaderID) from @THeader, mtblTransactionAllocation - do the updates on the table variable

Update @THeader
set ApplyAmt = (SELECT mtblTransactionAllocation.Amount
FROM mtblTransactionAllocation where mtblTransactionAllocation.DRID = TransactionHeaderID and
mtblTransactionAllocation.CRID = 187 and PatientID = 9) from @THeader, mtblTransactionAllocation - do the updates on the table variable

- below is where the problems occur. It occurs with statements referencing columns in the table variable, i.e. @THeader.ApplyAmt

UPDATE mtblTransactionHeader
SET mtblTransactionHeader.TransactionAllocationAmount = @THeader.TransactionAllocationAmount,
mtblTransactionHeader.ApplyAmt = @THeader.ApplyAmt
FROM @THeader, mtblTransactionHeader
WHERE @THeader.TransactionHeaderID = mtblTransactionHeader.TransactionHeaderID - put the values back into original table

Thanks in advance

Visual Studio Closes When Accessing The Columns Tab Of A Lookup Transformation Referencing SQL 7 Table

Jul 30, 2007

I'm creating a new Integration Services Project that copies data out of a SQL 7 server, transforms it, and places the data on a SQL 2005 (SP 2) Server. When defining a lookup transformation, if I specify an OLE DB Connection to my server running SQL 7 as the reference table, as soon as I click on the Colums tab, Visual Studio closes / crashes and dumps me to windows. I don't get an error message. If however I specify a connection to a server running SQL 8, or SQL 2005, no problems.

Is this supposed to happen?

My workstation is running Windows XP Pro SP2, Visual Studio 2005 Pro.

Microsoft SQL Server Integration Services Designer
Version 9.00.1399.00

The server that doesn't work for a reference table is running Windows 2000 Server SP4
SQL 7.00.623

Thanks for your help,

I am looking for a Sql query to verify the inserted values from one table(in CSV file) with another table(in sql database)

For example: I have below Values column that is present in once CSV file, after my data migration the values get stored in Results table under Message column.

I need to very whether values(1X,1Y) are inserted in Message record "successfully inserted value 1X"

Values (CSV)

Results Table(SQL)
CreatedDate                   Message
2015-08-04 08:45:29.203  successfully inserted value 1X
2015-08-04 08:44:29.103  TEst pass

2015-08-04 08:30:29.203  Test Pass
2015-08-04 08:28:29.203  successfully inserted value 1Y

If all values are inserted:

All values from values table are inserted successfully
Total count of values inserted: 2
If only few values are inserted, example only 1X from Values table is inserted in Message

Transact SQL :: Retrieve Currently Created Date From Master Table To Load Into Parent And Child Table

May 12, 2015

In Master tabel i have these date datas




SO when i try to load from  Master table to parent and child table i am using using expresssion like 

WHERE convert(date,A.[FtpDate]) = convert(date,GETDATE())  and convert(date,B.Ftpdate) = convert(date,getdate()) ;

If i use this Expression i am getting the current system date data's only  from Master table to parent and child tables.

My Problem is If i do this in my local sserver using the above Expression if i loaded today date and if need to load yesterday date i can change my system date to yesterday date and i can run this that yeserday date data alone will get loaded from Master to parent and  child tables.

If i run this expression to remote server  i cannot change the system date in server.

while using this Expression for current date its loads perfectly but when i try to load yesterday data it takes current date date only not the yesterday date data.

What is the Expression on which ever  date i am trying load in  the master table  same date need to loaded in Parent and child table without changing the system Date.

FROM #revf
WHERE fi_gnmaid IN (
SELECT DISTINCT r2.fi_gnmaid
FROM #revf r1, #revf r2

I don't want to create this #rev table so that i can avoid the delete statement. But data should not affect. Can i rewrite the above as below:

SELECT [Cusip], [sponfID], GroupSeries, [tran], [AddDate], [SetDate], [PoolNumber], [Aggregate], [Price], [NetAmount], [Interest],
[Coupon], [TradeDate], [ReversalDate], [Description], [ImportDate], MAX([fi_gnmaid]) AS Fi_GNMAID, accounttype, [IgnoreFlag], [IgnoreReason], IncludeReversals, DatasetID, [DeloitteTaxComments], [ReconciliationID],

Transact SQL :: Insert A Record Into Second table Where There Is Not A Match In First Table
