Replicating "join" Tables
May 13, 2001
Hi,
I have a number of "join" tables ie joins records from two other tables for example, an employee may be responsible for more than one product so the join table would look like this:
table name: employee_products
Employee_id foreign key from employee table
product_id goreign key from products table
My question is, how do I replication this table? Replication requires all table to have a primary key field. In this case, both fields are foreign keys and I dont have a primary key as the same data appears regularly in either field.
How should I get around this so I can implement replication? I dont want to have to add another field to be the primary key field.
Thanks

I have a table that is used for reporting, the problem is that the data in the table is refreshed every 30 minutes with a bulk insert. I am trying to find a way to have two tables that are mirror images of each other and when the loading table is loaded, then the table assumes the identity of the reporting table. The basic prinicpal is I need to have the table be available almost all the time and when the bulk insert is happening, users cannot query. Any help would be greatly appreciated.
Thanks in advance

I can't seem to find the answer to this in the documentation.
I have several tables that I want to replicate via transactional replication. These tables do have some foreign keys between them.
What are the advantages/disadvantages of "one table per publication" versus "one publication with all of these tables listed as articles"?
If I do not define these in the same publication, will I get into trouble with the order that data is loaded to satisfy the foreign key constraints?

Hi,
Please let me know if it is possible to replicate a table with identity property defined in it. Both the publisher and subscriber tables have identity property defined. Which option should be used while setting up transactional replication to allow the identity values at the publisher pushed to the subscriber, which also has identity property defined? Not for replication option with the identity property also fails. Whichever option I choose I get the error, 'An explicit value for the identity column in table 'jobs_id_nfr' can only be specified when a column list is used and IDENTITY_INSERT is ON.' This works only if the identity property is not defined at the subscriber. But, I need to have the identity property defined at the subscriber also because the subscriber should be an exact copy of production.
Thanks in advance,

When replicating a table which has an identity column I get the error: "Procedure cp_insert_tblname expects parameter @C1, which was not supplied.". The stored procedure appears to be called without any parameters so my insert stored procedure does not work. I know I'm missing something basic here!! Do I have to add the field names when telling replication to use a custom stored procedure. If not, how do arguments get passed to my SP, as globals somehow?
Any info greatly appreciated!!
Thanks,
Jay

Client is running X- version of application and corresponding database size is huge. Now client's vendor is releasing Y-version of same application with many database schema changes (like new tables added, new columns added, renamed existing columns and etc) To upgrade to the Y-version, vendor is suggesting to my client that down the system and do the upgrade for application/database to Y-version. We are sure that this process will take days together to upgrade to the Y-version. My client is not ready to down the system for that long. So we are trying to find the solution with minimal down time.The approach we are thinking is,
1) Create the replicated database to another server (server2) from production server(server1) using golden gate with X-version
2) Create new tables/schema updated tables from Y-version database on same server1. Here for Updated schema tables we are planning to use the name <table_name_Y_version> as the same table name exists in X-version.
3)With above 2 steps, golden gate replicate the changes from production to server1 and server1 will have the new Y-version table schema (with different concatenate name ' _Y_version'). BTW , there is no affect for the production
4) At this stage we are planning to find best approach, to fill the '<table_name>_Y_version' from X-version tables. two challenges here a) all data needs to be moved to Y-version tables b) they have to sync data in real time.
we thought of going to
a) ssis package to pump the data to Y-version tables, but real time data will not sync.
b) trigger based technique, previous experience said, lot of load
c) thinking about sql replication.

when i do a snapshot i have it set up to truncate before inserting. As a result I'm getting an error saying that it cant truncate a table reference in an indexed view. What settings should i use to allow for a snapshot in this instance? Should i manually drop the databinding then snap then recreate the databinding? there has to be a better way

I need to copy all the data from all the tables in a database to a copy of this database on another server.
What feature of SSIS should I take advantage of to accomplish this?
We have an SLA for 8am, most times the data warehousing jobs complete at 8:05am. Adding an additional process/set of tasks to this package would obviously make matters so I'm trying to update/copy/replicate the data in the fastest manner. Typically we're talking 2 marts (10-20GB) with 2 large tables (5-10 mill records) and 20 marts (0.5 - 5 GB) with many more smaller tables (~40 tables with record count ranging from 1 to a million)
Additionally please indicate if the design/feature you suggest can handle (pushing schema changes and additions to the target server) schema changes or new tablesviews added to the source database.
My only idea so far...is using the import wizard (in Management Studio) to create an SSIS package (top copy all the tables from one server to another) and saving it to the server, Then executing this package after the job is complete. However this would not work if the schema of a table changed, or if a a table is added. Moreover I don't think I can edit this package in visual studio.

Hi guys,
I'll appreciate any help with the following problem:
I need to retrieve data from 3 tables. 2 master tables and 1 transaction table.
1. Master table TBLOC contain 2 records :
rcd 1. S01
rcd 2. S02
2. Master table TBCODE contain 5 records:
rcd 1. C1
rcd 2. C2
rcd 3. C3
rcd 4. C4
rcd 5. C5
3. Transaction table TBITEM contain 4 records which link to 2 master table:
rcd 1. S01, C1, CAR
rcd 2. S01, C4, TOY
rcd 3. S01, C5, KEY
rcd 4. S02, C2, CAR
I use Left Join & Right Join to retrieve result below (using non-ASNI method) but it doesn't work.
Right Join method:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A RIGHT JOIN TBCODE B ON A.CODE = B.CODE
RIGHT JOIN TBLOC C ON A.LOC = C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
When I use Non-ASNI method it work:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A, TBCODE B, TBLOC C
WHERE A.CODE =* B.CODE AND A.LOC =* C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
Result:
LOC CODE ITEM
-----------------------------
S01 C1 NULL
S01 C2 NULL
S01 C3 CAR
S01 C4 TOY
S01 C5 KEY
S02 C1 NULL
S02 C2 CAR
S02 C3 NULL
S02 C4 NULL
S02 C5 NULL
Please Help.
Thanks.

I need to perform a join on six different tables to produce a report. The biggest join I have ever done has been four tables. The way I did that query was to join three tables and then to perform the final select on the three table join.
Can anyone give me some advice. Should I use the same approach? Or can I just continue to use the keyword INNER JOIN to perform the joins?

I have three tables:
1) Orders - order_id, orderdate
2) ordersdetails - order_id, partnumber, qty
3) products - partnumber
I need an output in following format
Date Partnumber qty
Following query gives the desired results.
select left(orders.orderdate,11) as date, orderdetails.partnumber, SUM(orderdetails.qty) as total
from orderdetails, orders
where orderdetails.partnumber is not null
and orderdetails.order_id = orders.order_id
and orders.orderdate >= {ts'2001-05-01 00:00:00'} and orders.orderdate <= {ts'2001-05-31 23:59:59'}
group by orders.orderdate, orderdetails.partnumber
order by orders.orderdate, total
But I do not have part that have null orders. My goal is to get
1) Get all part numbers, qty in the month of May.
2) at the end attach all partnumbers that have null ordered values to see which one have no orders.

Thank you, Thank you for reading my question!!! :)
I have 3 tables that need to be joined.
(Not necessarily needed info but might help: using Coldfusion with ODBC to Foxpro database)
Table 1: Timecard
--------
loginname date wrknum time
----------- --------- --------- ------
afrank 7/17/06 1 3
afrank 7/17/06 2 2
afrank 7/17/06 3 3
afrank 5/20/06 1 3
rjohn 7/17/06 1 3
.....
Table 2: Defaults
-----------
loginname wrknum
----------- ---------
afrank 1
afrank 2
afrank 3
afrank 4
afrank 5
....
Table 3: Workorders
wrknum description
---------- ---------------
1 descrip1
2 descrip2
.....
The result needs to be for the user afrank, date=7/20
and would look like:
Resultant Table:
loginname wrknum time description
----------- ---------- ------ ------------
afrank 1 3 descrip1
afrank 2 2 descrip2
afrank 3 3 descrip3
afrank 4 NULL descrip4
afrank 5 NULL descrip5
I've tried an outer left join but cannot get the right data. Basically everything from the timecard table and the leftovers from the default table with descriptions for all.

I've got two tables, one called clientsharedeals and the clientorderdeals. In the first table, I have four fields (Rundate, Accno, Dealid, Nominal) that I need to sum(Nominal), grouping by dealid.
Once I've done this, I need to join to clientorderdeals, also having the same fields plus one extra (Rundate, Accno, Dealid, Nominal and Dealseq). Because of Dealseq, I can have more than one row in the table, matching (Rundate, Accno, Dealid, Nominal) of the first table. However, Dealseq increments, so I need to select max(Dealseq).
My query is doubling up on nominal because in my select statement, I am only using one account number, so I know what the value is for nominal and there are two rows in clientorderdeals - and it is not selecting max(dealseq) but both.
Can someone please cast some pearls my way ?

Could somebody please explain to me how do we join a table onto itself as that is what I was advised to do but I can't quite get where I want to go.
What I want to do is list values from a table,but those values can be just a quote (what would cost if they decided to go for that option) or those values can represent what was spent and invoiced, what is confusing me is that all of that gets saved in the same table and in same columns, so what was quoted for example for AirFares and what was spent gets saved in the same record but when it is "quoted amount" then ID = 1 but when it is invoiced ID = -1 and that is how we know what was quoted and what was invoiced.
But I need to split that one field into two columns one showing AirFareQuoted and one AirFareInvoiced and i have no idea how to achieve this.
I hope this makes sense and somebody can help me

Hey Folks,
I am stuck at one place in data migration........ I have the following source tables having no PK / INDEX / Constraint defined on any of them........
T1
(
ID1 INT,
STYLE VARCHAR(34)
)
T2
(
COL_ID VARCHAR(34),
OBJ_ID VARCHAR(34)
)
T3
(
OUT_ID VARCHAR(34),
ITEM VARCHAR(34),
)
And here is the relation..........
Quote:
T1.STYLE = T2.COL_ID
T2.OBJ_ID = T3.OUT_ID
T3.ITEM = T2.COL_ID
Here is what I have tried with.........
Quote:
SELECT * FROM T3 WHERE ITEM IN
(
SELECT COL_ID
FROM T1
INNER JOIN T2
ON
T1.STYLE = T2.COL_ID
INNER JOIN T3
ON
T2.OBJ_ID = T3.OUT_ID
)
But this query is not helping me out. I mean the number of output records are 0.
Now can any one suggest me a join that includes all the 3 tables, or finetune my query?

hi everybody
I have a question and need answer as soon as possible. so i hope i get help. How can i join two tables have no common fields? I tried outer join but i get redundant data(repeated values).
Give me a script to solve the following problem . There are no real wrong answers, but the more efficient and bulletproof the query is the better. Assign rooms to classes based on capacity using the Classes and Rooms tables. Rules: each class should have a room (and NULL if a room is not available). No class can be in a room where there are more students than capacity. No room can be used twice.
And this is the tables query:
CREATE TABLE Classes (
ClassID int NOT NULL,
Class varchar (50),
Students int NOT NULL, CONSTRAINT PK_Classes PRIMARY KEY CLUSTERED (ClassID
) )
GO
CREATE TABLE Rooms (
Room int NOT NULL,
Capacity int NOT NULL,
CONSTRAINT PK_Rooms PRIMARY KEY CLUSTERED (Room)
)
GO
INSERT INTO Classes (ClassID, Class, Students) VALUES (1, 'Whats New for SQL Server 2008', 65)
INSERT INTO Classes (ClassID, Class, Students) VALUES (2, 'Introduction to Silverlight 1.1', 52)
INSERT INTO Classes (ClassID, Class, Students) VALUES (3, 'XQuery Deep Dive', 35)
INSERT INTO Classes (ClassID, Class, Students) VALUES (4, 'Ranking and Windowning', 35)
INSERT INTO Classes (ClassID, Class, Students) VALUES (5, 'Expression Blend 1.1', 65)
INSERT INTO Classes (ClassID, Class, Students) VALUES (6, 'Database Design Patterns', 75)
INSERT INTO Classes (ClassID, Class, Students) VALUES (7, 'CrossTabs for Dummies', 1)
INSERT INTO Rooms (Room, Capacity) VALUES (221, 30)
INSERT INTO Rooms (Room, Capacity) VALUES (222, 40)
INSERT INTO Rooms (Room, Capacity) VALUES (223, 50)
INSERT INTO Rooms (Room, Capacity) VALUES (224, 60)
INSERT INTO Rooms (Room, Capacity) VALUES (225, 70)
INSERT INTO Rooms (Room, Capacity) VALUES (226, 74)

hi,
i am facing an issue. i have got two tables say table1 and table2.
table1 has column1,2,3 ( has values a,b,c) where as table 2 has different columns 4,5,6(j,k,l).
column4 in table 2 has value which contains %+column1+% and it has two entires for each row in table1.the column4 value in table2 is different for all rows.When i am trying to join the two tables, i am getting values like
1 2 3 4 5 6
a b c j k l
a b c j1 k l
a1 b c j k l
a1 b c j1 k l
but i want to display
a b c k l
a1 b c k l
is there a way to do it.
My queries were
select distinct pc_assign_worklist.pxRefObjectInsName AS [pxRefObjectInsName],
pc_assign_worklist.pxUrgencyAssign AS [pxUrgencyAssign],
pc_assign_worklist.pyLabel AS [pyLabel],
pc_assign_worklist.pyAssignmentStatus AS [pyAssignmentStatus],
pc_assign_worklist.pxAssignedOperatorID AS [pxAssignedOperatorID],
CONVERT(char (11),pc_assign_worklist.pxCreateDateTime) AS [pxCreateDateTime],
pc_assign_worklist.pxCreateOpName AS [pxCreateOpName],
pc_index_workparty.MemberIdentifier AS [MemberIdentifier],
pc_index_workparty.LastName AS [Last Name],
pc_index_workparty.FirstName AS [First Name],
pc_index_workparty.pxInsName AS [pxInsName],
pc_index_workparty.pzInsKey AS [pzInsKey],
pc_index_workparty.pxpartySubscript as "Workparty"
from dbo.pc_assign_worklist
LEFT OUTER JOIN dbo.pc_index_workparty
ON pc_index_workparty.pzInsKey LIKE '%' + pc_assign_worklist.pxRefObjectInsName + '%'
where
pxAssignedOperatorID = 'dasxkx1'
i also tried left inner join but it always returns the same result seta.
I even created a view by inner join of two tables and then did left outer join on the second table . The result is same.
Can somebody tell whether this is achivable or not.
