Is there any possibility to create a foreign key references more than one tables.
say for example,
Create table sample1(id int primary key)
Create table sample2(id int primary key)
Create table sample3(
id int primary key,
CONSTRAINT fk1 FOREIGN KEY REFERENCES sample1 (ID),CONSTRAINT fk1 FOREIGN KEY REFERENCES sample2 (ID))
this shows no error while creating, but in the data insertion it shows error..
I want to create a table withmember id(primary key for Students,faculty and staff [Tables])and now i want to create issues[Tables] with foreign key as member idbut in references i could not able to pass on reference as orcondition for students, faculty and staff.Thank You,Chirag

I have two (or more) tables defined as follows.
Code SnippetTable1 Table2
Id [uniqueidentifier] Id [uniqueidentifier]
[...] [...]
Now, I would like to create a table Table3 that has its own primary key and references Table1 OR Table2.
Code Snippet
Table2
Id [uniqueidentifier]
ForeignId [uniqueidentifier, references Table1 or Table2]
This would enable me to insert any value into ForeignId that is present as the Id field in Table1 or Table2. Is this possible?

Is there anyway to get the order in which data to be import on to tables when they have primary and Foreign Key relations?
For ex:We have around 170 tables and when tries to insert data it will throw error stating table25 data should be inserted first when we insert data in table 25 it say 70 like that.
Assume i have 3 tables
Person(personname,age)
Children(childname,personname)
car(carname,personname)
A persone can have multiple cars
A person can have multiple children
Its not possible to display the results in SQL rows and columns.
If i try to it will give
PersonName Carname Childname
Sachin Audi C1
Sachin Maruti C1
Sachin Audi C2
Sachin Maruti C2
Instead of writing seperate queries the application wants to receive an xml output as follows
<person>
<pname>sachin</pname>
<car>audi</car>
<car>bmw</car>
<cname>c1</cname>
<cname>c2</cname>
<person>
How to get this output ?

I need to consume a live data feed from a golf tournament. And by consume, I really mean insert (merge) into our own SQL Server database on a regular intervals as a tournament progresses.This site didn't let me upload an XML file, but you can see a sample of the data feed here: URL....
I need to insert this data into 2 tables, Player_Holes and Player_Shots. But while doing the insert, I need to lookup several things such as our player ID match to theirs on an external_id against the players table. The shot types translation, and some other logic about the process overall.
The columns in my player_holes tables are: id, player_id, hole_id, round, shots (this is a total # of strokes) and date_created/date_modified.Shots table is similar: id, player_id, hole_id, round, shot_number, shot_type_id, club, distance, date_created/date_modified.
The only way I know how to do it, is inefficient. I would parse the XML in ColdFusion (please no comments on ColdFusion, that's what we use for webdev), and then loop over it and do inserts for each player, each hole for each round, and the shots would probably be separate for each hole.
It would be so much better and more efficient if I could do it in SQL directly. I've done some research and SQL Server Data Tools looks promising. I've never used it, so would have to learn, but also I'm not sure if that'd work in this application when we want to run is as a scheduled task every few minutes.

Hello:
Need some serious help with this one...
Background:
Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...
Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.
The Problem:
There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.
This appears possible in SqlServer too --...as long as there are no CASCADE operations.
Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.
So -- please correct me if I am wrong here -- it appears that the operations would be
along the lines of:
a) Remove the Foreign Key references
b) Copy the table structure, and make a new temp table, adding the column
c) Copy the data over
d) Add the FK relations, that used to be in the first table, to the new table
e) Delete the original
f) Done?
The questions are:
a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'.
b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant?
c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.
Thanks!

Hello and thank you for the help in advance.
I know this has to be possible maybe I am just missing somthing.
I am creating a matrix report which will compare year by year quotes to orders The issue is quotes and orders each have their own dataset. I will be pivoting on JobType which is in both datasets and spelled the same. Is there a way to do this or will I have to figure out how to union the tables? If not possible why does it allow you to name the dataset in the expression?
Thanks, Leo
I have a database of 900+ tables with around 3000 SPs, and views. Manually I reviewed few tables and found that tables are not referenced with FK and I applied few. There are lots of tables and SPs using them in join statement, Is there any way with which I can get each tables missing references, any DMV or other manual script which tells about this?
View 2 Replies View RelatedI've just found out about the concept that a table should only be references by foreign keys a maximum of 253 times throughout the database. I was hoping someone could give me a better idea of the dangers of disregarding this recommendation.
In our database, we have a Users table, which contains all of the users of a given system. In nearly every other table in our database, we have a field to indicate which user created the record. This is a reference back to the Users table. But as the number of tables has grown, we've surpassed that 253 limit. All I can tell, practically, is that I can no longer delete from the Users table. The query will fail, telling me the query optimizer ran out of memory, and that I should simplify my query.
The Users table is the only table that even comes close to this number of foreign key references. I don't even mind being unable to delete from the table. I'm mostly wondering if there are other problems with my design that will cause issues?
Is there a better way to keep track of who created a record in the database? Is it bad design to reference my Users table in so many places?
Thanks,
I have 3 tables , Customer , Sales Cost Charge and Sales Price , i have join the customer table to the sales price table with a left outer join into a new table.
i now need to join the data in the new table to sales cost charge. However please note that there is data that is in the sales price table that is not in the sales cost charge table and there is data in the sales cost charge table that is not in the sales price table ,but i need to get all the data. e.g. if on our application it shows 15 records , the sales price table will maybe have 7 records and the sales cost charge table will have 8 which makes it 15 records

I have a table tbl_rules. This table will define rules for each role. I have not yet defined the fields for the rules. But the table definition is as below:
Create table tbl_Rules

primary key (ID),
constraint fk_RoleName foreign key (Role_ID)

ID RoleName
1 Manager
2 Analyst
3 Admin
So far so good. I created the tbl_rules.

ID Role_ID
1 Manager
2 Admin
Instead it shows:
ID Role_ID
1 1
2 3
Is there a way to do this? The goal is to return the select * from tbl_Rules results to a gridview to enable adds and changes. I could do this by doing queries for each column, but I was hoping to make it easier. Not sure if this is even possible.

An SSIS task imports data from a flat file and inserts the data into a staging table. The staging table holds the data in its raw form. A second process then selects the data from the staging table, looking up the foreign key id's for raw data values, and then inserts the data into the live table.
SQL - Only key columns shown for clarity
-- Staging Table
CREATE TABLE Staging
(Information VARCHAR(10),
MachineName VARCHAR(10),
Status VARCHAR(10))
[code]...
The insert into the live table should look up the id for machine 1, and the id of status success and insert the foreign key values into the live table for the row.There could be 1000's of rows for the output of machine 1 all with different status's - (all pre set in the Status table, i.e success, failure, rerun) and the same for lots of other machines held in the machine table.
What is the best to insert this data all in one go, rather than reading each row of the staging table one by one, looking up the foreign key values depending on the machine and status values, then inserting the data.
I was thinking along the lines of:
INSERT INTO dbo.LiveTable
(Information, MachineID, StatusId)
SELECT Staging.Information, dbo.Machine.MachineId, dbo.Status.StatusId
FROM dbo.Staging
JOIN Machine ON Machine.MachineName = Staging.MachineName
JOIN STATUS ON Status.Status = Staging.Status But I notice the problem with this is, it doubles up the inserts!
In a special request run, I need to update locker and lock tables in a sql server 2012 database, I have the following 2 table definitiions:

[schoolID] [int] NOT NULL,
[number] [varchar](10) NOT NULL,
[lockID] [int] NULL

The locker table is the main table and the lock table is the secondary table. I need to add 500 new locker numbers that the user has given to me to place in the locker table and is uniquely defined by LockerID. I also need to add 500 new rows to the corresponding lock table that is uniquely defined in the lock table and identified by the lockid.
Since lockid is a key value in the lock table and is uniquely defined in the locker table, I would like to know how to update the lock table with the 500 new rows. I would then like to take value of lockid (from lock table for the 500 new rows that were created) and uniquely place those 500 lockids uniquely into the 500 rows that were created for the lock table.

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.
I am using the following select statement to get the row count from SQL linked server table.
SELECT Count(*) FROM OPENQUERY (CMSPROD, 'Select * From MHDLIB.MHSERV0P')
MHDLIB is the library name in IBM DB2 database. The above query gives me only the row count of table MHSERV0P. However, I need to get the names, rowcounts, and sizes of all tables that exist in MHDLIB librray. Is it possible at all?
Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob
