Insert Or Update SSIS For Composite Primary Key
Sep 1, 2006
Hi ,
We have scenario like this .the source table have composite primary key columns c1,c2,c3,c4.c5,c6 .when we move the records to destination .we have to check columns (c1+ c2 + c3 + c4 + c5 + c6) combination exist in the destination. if the combination exist then we should do a update else we need to do a Insert . how to achive this .we have tryed useing conditional split which is working only for a single Primary key . can any one help us .

Hello,
I have a table which has a composite primary key consisting of four columns, one of them being a datetime called Day.
The nice thing afaik with this composite key is that it prevents duplicate entries in the table for any given day. But the problem is probably two-fold
1. multiple columns need to be used for joins and I think this might degrade performance?
2. in client applications such as asp.net these primary keys must be sent in the query string and the query string becomes long and a little bit unmanagable.
A possible solutions I'm thinking of is dropping the existing primary key and creating a new identity column and a composite unique index on the columns from the existing composite key.
I would like to have some tips, recommendations and alternatives for what I should do in this case.

I have A Table , Which Primary key consists of 6 columns.
total Number of Columns in the table are 16. Now i Want to Convert my Composite Primary key into simple primary key.there are already 2200 records in the table and no referential integrity (foriegn key ) exist.

I've been facing this situation since long but today i am asking here. Suppose i have a following tables;
AdmissionInfo, AdmID, AdmDate, AdmFee etc.
SubjectInfo i.e. SubID, SubName, SubStatus etc.
The Result table is like this:
ResID, AdmID, SubID, TheoryMarks, PracticalMarks, ObtMarks, TotalMarks, ResultTerm, SubPercentage.
ResID is PK, AdmID and SubID are Foreign Keys, right. Now What i want to ask/ learn that Am i suppose to combine ResID, AdmID and SubID as a composite PK or should i simply make the ResID as PK and other 2 be there as FK? When do we really need to use Composite PK and using it a good thing or not?

i have a master table with around 15 columns and i am trying to findthe appropriate primary keys and indexes for the table.To make the records unique, i need to include two datetime columns (start and end dates ) and two integer columns ( attributes of therecord ) to make up a composite primary key. Both of these fourcolumns are found in the WHERE clause of my queries.Is it acceptable in the view of performance and how should i createthe indexes?

This is really not a T_SQL question but there's no good category for it so I thought I'd just put it here.
I have a table that will contain a large amoutn of data in one field, and every piece of this data is uniquely identitied by six other attributes, that is, six other fields (e.g. user_ID, type_ID, year, country, state, item_ID). I can either make these six fields into a composite primary key, or add an additonal field (say an identity column) as the primary key and add a unique constraint on these six fields. What are the pros and cons of both designs? The one data field is of nvarchar(2000) type and the table is likely to have 50 million+ rows in a couple of years of real use.
This table is not referenced by any other tables so whatever the primary key is, there's no FK reference. However, there could be FK references to this table in the future. Does the FK possibility make a difference in the design considerations?

Hello,
Does composite primary key affect performance on the table that contains the composite primary key or tables that references this table?
When composite primary key should be used?

Hi
I'm trying to create a composite Primary Key on a table. This is the SQL I've written:
CREATE TABLE BookingItems
(
BookingID INT NOT NULL
REFERENCES Bookings(BookingID),
EquipmentTypeID INT NOT NULL
REFERENCES EquipmentType(EquipmentTypeID),
CONSTRAINT PK_BookingItems_id PRIMARY KEY
(BookingID, EquipmentTypeID)
)
Is this right? I'm trying to define a Primary Key made up of BookingID and EquipmentTypesID, which are both Foreign Keys as defined in the column definition.
Thanks

Newbie question...
I have two tables (categories & listings) which create a many-to-many relationship.
I have created an interim table with the primary keys from each table as a composite primary key...(cat_id & list_id).
How does the interim table get populated with the id's?
When I do an insert statement to insert data into the categories table, the cat_id field is automatically generated...same with the listings table, but when (and how) does the primary key data get into the interim table.
Thanks in advance for the assistance.

I'm trying this
Code:
CREATE TABLE Rating
(ContentID int NOT NULL PRIMARY KEY REFERENCES Content_(ContentID),
UserID int NOT NULL PRIMARY KEY REFERENCES Usr(UserID),
rating tinyint DEFAULT 2,
LastRead smalldatetime NOT NULL DEFAULT CURRENT_TIMESTAMP)
And it is telling me this:
Msg 8110, Level 16, State 0, Line 14
Cannot add multiple PRIMARY KEY constraints to table 'Rating'.
So how do I combine two non-unique foreign keys, the combination of which is unique, into one primary key?

My previous post was not really clear, so I'll try again with a (hopefully) better (even if longer) example...
Consider the following...
A JOB describes the processment of a document.
Each document can exist in two versions: English and French.
A JOB can have 1 or 2 TASK, each describing the processement of either the English or French version.
So we have the following:
A: JOB (JobNum [PK], DocReference, StartDate, EndDate, ...)
B: TASK (JobNum [PK] [FKa], Version [PK], Priority, ...)
that is there is an identifying 1:M (where maxium allowed for M is 2) relationship between JOB and TASK; TASK being identified by JobNum and Version (where the domain for Version is {E, F}).
Each TASK may require a TRANSLATION sub_task.
Each TASK may require a TYPING sub_task.
Each TASK may require a DISTRIBUTION sub_task.
For example, for a given doc, the English TASK requires TRANSLATION and DISTRIBUTION, while the French only DISTRIBUTION.
That is, there is a 1:1 not-required relationship between TASK and TRANSLATION, TYPING and DISTRIBUTION.
So we have the following:
A: JOB (JobNum [PK], DocReference, StartDate, EndDate, ...)
B: TASK (JobNum [PK] [FKa], Version [PK], Priority, ...)
C: TRANSLATION (JobNum [PK] [FKb], Version [PK] [FKb], DueDate, ...)
D: TYPING (JobNum [PK] [FKb], Version [PK] [FKb], DueDate, ...)
E: DISTRIBUTION (JobNum [PK] [FKb], Version [PK] [FKb], Copies, ...)
As you can see I am using the PK of TASK as FK and PK for each of the three SUB_TASKs.
To complicate things, each SUB_TASK has one or more assignments. The assignments for each SUB_TASK records different information from the others.
So we have...
A: JOB (JobNum [PK], DocReference, StartDate, EndDate, ...)
B: TASK (JobNum [PK] [FKa], Version [PK], Priority, ...)
C: TRANSLATION (JobNum [PK] [FKb], Version [PK] [FKb], DueDate, ...)
D: TYPING (JobNum [PK] [FKb], Version [PK] [FKb], DueDate, ...)
E: DISTRIBUTION (JobNum [PK] [FKb], Version [PK] [FKb], Copies, ...)
F: TRA_ASSIGN (JobNum [PK] [FKc], Version [PK] [FKc], Index [PK], Translator, ...)
G: TYP_ASSIGN (JobNum [PK] [FKd], Version [PK] [FKd], Index [PK], Typyst, ...)
H: REP_ASSIGN (JobNum [PK] [FKe], Version [PK] [FKe], Index [PK], Pages, ...)
that is there is an identifying 1:M relationship between each SUB_TASK and its ASSIGNMENTs, each ASSIGNMENT being identified by the SUB_TASK it belongs to and an Index.
I wish I could send a pic of the ER diagram...
Maybe there is another and better way to model this: if so, any suggestion?
Given this model, should I use for TRANSLATION, TYPING and DISTRIBUTION a surrogate key, instead of using the composite key, like for example:
C: TRANSLATION (TranslationID [PK], JobNum [FKb], Version [FKb], DueDate, ...)
D: TYPING (TypingID [PK], JobNum [FKb], Version [FKb], DueDate, ...)
E: DISTRIBUTION (DistributionID [PK], JobNum [FKb], Version [FKb], Copies, ...)
this will "improve" the ASSIGNMENTs tables:
F: TRA_ASSIGN (TranslationID [PK] [FKc], Index [PK], Translator, ...)
G: TYP_ASSIGN (TypingID [PK] [FKd], Index [PK], Typyst, ...)
H: REP_ASSIGN (DistributionID [PK] [FKe], Index [PK], Pages, ...)
I could even go further using a surrogate key even for TASK, which leads me to the following:
A: JOB (JobNum [PK], DocReference, StartDate, EndDate, ...)
B: TASK (TaskID [PK], JobNum [FKa], Version , Priority, ...)
C: TRANSLATION (TaskID [PK] [FKb], DueDate, ...)
D: TYPING (TaskID [PK] [FKb], DueDate, ...)
E: DISTRIBUTION (TaskID [PK] [FKb], Copies, ...)
F: TRA_ASSIGN (TaskID [PK] [FKc], Index [PK], Translator, ...)
G: TYP_ASSIGN (TaskID [PK] [FKd], Index [PK], Typyst, ...)
H: REP_ASSIGN (TaskID [PK] [FKe], Index [PK], Pages, ...)
I don't really like this second solution, but I'm still not sure about the first solution, the one with the surrogate key only in the SUB_TASks tables.

Hi All,
I have a table that has 3 columns, two of them make a composite primary key. The table is populated with data. What I need to do is to add a third column to a composite primary key. I have tried to do that with the following command:
alter table databasesize
add constraint pk_dbsize primary key (dbid)
But I get the error message:
Table 'databasesize' already has a primary key defined on it.
How can I do this?

Hi,
I'm currently writing a small application that is using SQL Server as a back-end database. A part of my database looks something lie the following:
Tables:
Orders(OrderId[int, PK], OrderDescription[varchar] etc...)
OrderLines(OrderId[int, PK, FK], OrderLineId[int, PK], etc...)
What I need to achieve is - everytime that a new line is inserted into an orderlines table part of the primary key will be the OrderId and the OrderLineId should be auto-incremented from 1 for each OrderId in the OrderLines table.
I know i can do this manually in my program, but i'm just wondering if theres a way to achive this in SQL Server?
Thanks,
Nick Goloborodko

since ten years perhpas the society has a database with some table (person, country, and so on)since last years , the project manager decides to create a new database with some new design because before some information was save in one table well, the problem is when we pass all application to the new model we've notice that some id are not the same !
sample :
table Language old model
-------------------------
id frenchDescription english description
----------------------------------------
3 Anglais English
.....
......
table Language new model
id frenchDescription english description
-----------------------------------------
5 Anglais English
.....
.....
Alright , you can understand that the new model must be the same id => 3
my question is how to modify id on the table ?

Hi,
I have a doubt, can anyone please clarify me.
I have created the following table,
create table z
(
eno int,
deptno char(2),
ename varchar(5),
constraint pk_eno_deptno primary Key(eno,deptno)
)
and I tried to establish a foreign key based on the above defined table. It's giving error,
create table z_dup
(
eno int FOREIGN KEY REFERENCES z(eno),
deptno char(2)
)
go
Error:-
*****
There are no primary or candidate keys in the referenced table 'z' that match the referencing column list in the foreign key 'FK__z_dup__eno__18CE1BA6'.Could not create constraint. See previous errors.
Even I tried to create a foreign key like the following,
create table z_dup
(
eno int FOREIGN KEY REFERENCES z(eno,deptno),
deptno char(2)
)
go
Error:-
********
More than one key specified in column level FOREIGN KEY constraint, table 'z_dup'.
Can anyone please help me to create a foreign key relation with the base table.
tks in advance,

Primary key (A1, A2).
Table -B
Column B1 Primary key.
Column B2 not null

NOTE:
I am not interested in any responses that want to argue the use of a unique ID field and autonumbering as the PK. It is quite clear from the forums that this subject is a polarizing one. This question is for those who follow text-book design practices and believe that a composite primary key should be used when it is available. I want to be one of them for the time being.
SYNOPSIS:
I have three tables, TestSummary, TestDetails, and Steps.
The TestSummary table looks like this:
Create table TestSummary
(
TestSummaryID int identity primary key,
...
SequenceID int not null
)
It contains the date and time of the test, the serial number, the part number, the test operator's name, and the ID of the sequence of steps used during the test. It uses a unique ID field for the primary key.
The TestDetails table looks like this:
Create table TestDetails
(
TestDetailsID int identity primary key,
TestSummaryID int not null,
StepID int not null,
...
)
It contains the details of the test like voltage readings, current readings, temperature, etc., one record per reading. It also contains the step number of the test sequence specified in the TestSummary table.
The Steps table looks like this:
Create table Steps
(
SequenceID int not null,
StepID int not null,
Function int not null
Primary key (SequenceID, StepID)
)
It contains a list of all of the functions to be performed on the device under test by sequence number and the step number within the sequence.
When I try to establish a relation between TestSummary.SequenceID and Steps.SequenceID, SQL Server flags an error because TestSummary.SequenceID and Steps.SequenceID:Steps.StepID do not match.
What is the problem with this approach?

Hi All
I hope someone smart can help me, it would be highly appriciated.
I am developing an SQL Serverdatabase and in on of the tables I need the primary key to consist of two pieces of data.
TblOrders: OrderNum, Orderdate, ....
TblDispatchers: DispatcerID, Dispatcher, DispatcherAddress
The OrderNum field in TblOrders need to be a composite of an AutoNum-field (incrementet by 1) and the DispatcerID from the tblDispatchers.
Can this be done, and how.
Many thanks
Kind regards

I have three tables that are important here, a 'Plant' table a 'Spindle' table and a 'PlantSpindle' table. The 'PlantSpindle' is comprised of a PlantID and a SpindleID acting as the Primary Key for the table with no other fields.
I have an aspx page that captures the appropriate data to create an entry in the Spindle table. Depending on the user, I will know which plantID they are associated with via a querystring. In my storedproc I insert the data from the webform into the Spindle table but get stuck when I try to also insert the record into the PlantSpindle table with the PlantID I have retrieved via the querystring and the SpindleID of the spindle record the user just created. Basically, I am having trouble retrieving that SpindleID.
Here is what I have in my storedProc (truncated for brevity).
CREATE PROCEDURE [dbo].[InsertSpindle]
@plantID int,
@spindleID int,
@plantHWG varchar(50),
@spindleNumber varchar(50),
@spindleDateInstalled varchar(50),
@spindleDateRemoved varchar(50),
@spindleDurationMonths float(8),
@spindleBearingDesignNumber int,
@spindleArbor varchar(50),
@spindleFrontSealDesign varchar(50),
@spindleFrontBearing varchar(50),
@spindleRearBearing varchar(50),
@spindleRearSealDesign varchar(50),
@spindleNotes varchar(160)
AS
SET NOCOUNT ON
INSERT INTO Spindle
(plantHWG, spindleNumber, spindleDateInstalled, spindleDateRemoved, spindleDurationMonths,
spindleBearingDesignNumber, spindleArbor, spindleFrontSealDesign, spindleFrontBearing,
spindleRearBearing, spindleRearSealDesign, spindleNotes)
VALUES
(@plantHWG, @spindleNumber, @spindleDateInstalled, @spindleDateRemoved, @spindleDurationMonths,
@spindleBearingDesignNumber, @spindleArbor, @spindleFrontSealDesign, @spindleFrontBearing,
@spindleRearBearing, @spindleRearSealDesign, @spindleNotes)
SET @spindleID = (SELECT @@Identity
FROM Spindle)
INSERT INTO PlantSpindle
(plantID, SpindleID)
VALUES
(@plantID, @SpindleID)
I have guessed at a few different solutions but still come up with Procedure 'InsertSpindle' expects parameter '@spindleID', which was not supplied when I execute the procedure.
Any help would be appreciated! thanks!

I use SSIS for data's integration with a flat file to a table in sql server 2005.
In the table, i've a primary key [ArtID]. In the flat file, ArtID is duplicate and i've a date that i already sort to have a historic.
I use a script to know if the row must be inserted or be updated.
I use two sql command to insert and update data in server.
I test this in the script
count = select count(*) from table where primary key = value.
If (count = 0) then insert else update.
When i've a duplicate row in flat file i've a error with the primary key. I don't understand why i've it.
Perhaps the SQL Command commit all the row at the end of the flow.
If it's true, can i change the commit each time the line in flat file is readed !! In this case, how can i do that ??
Or i use a OLE Destination to insert with option table or view (no fast) to have a commit all the line of flat file ??
What do thing about it ??
Thanks a lot

Hi,
I have written one SSIS script for Initial data load. Then everyday, there will be an incremental insert and/or update; which means there needs to be a separate script for Incremental data load.
Currently, script for initial data load has scripts containing SELECT queries. it just copies the data from source table to the destination. How should I go about putting both initial & incremental scripts together? Is there any way or do I need to build 2 separate packages ?
Thanks :)

I have two tables from two different Databases
DB1.dbo.Table1 and DB2.dbo.Table2
eX:
Table 1

1 GYM ABC Y
1 TIM ABC N
1 PIN ABC N
2 QWE SAD Y

....
Table 2
KEY LName FName Updated
1 JIM ABC Y
2 QWE SAM Y
....
....
1) Table 1 and Table 2 are of same structure.
2) In table2, as in above example, few changes have beeen done for KEY1 AND Update =Y, Similarly KEY= 2 AND UPDATED=Y, like for KEY= 1 LName was changed to JIM instead of GYM and for KEY= 2 FName has been changed to SAM instead of SAD.
3) Now I want to do this in SSIS where
a) Its going to process rows of Table2 and check in table1 according to KEY and UPDATE=Y and update the Table1 with Updated = N and Insert that particulra process row of Table2 into Table1
and hence Resultant of Table1 must be like this
Table 1
KEY LName FName Updated
1 GYM ABC N
1 TIM ABC N
1 PIN ABC N
1 JIM ABC Y
2 QWE SAD N
2 QWE SAM Y
......
....
Can somebody help me how to do this in SSIS. Thnaks a lot in advance
