I have run into an issue that seems very simple but I am new to SSIS and DBs in general and therefore cannot solve it. I would like to take data from a SQL Server table, lookup a key from a dimension table and update the same SQL Server table with this data. Is there anyway to do an update using SSIS?
Thanks,
Curtis
Hi,
I use lookups to map surrogate of level 1 dimensions to my fact tables in SSIS.
But how to handle a level 2 dimension with a ValidFrom and a ValidUntil date field?
I do not use an IsCurrent column, because this could problem with late arriving facts.
- In dts I used an SQL statement like this:
update SA
SET SA.DimProdRef = Dim.RecordID
FROM SAWarenEingang SA, DimProd Dim
where SA.ProduktNumber = Dim.ProduktNumber
and SA.ArtikelkontoBewegungsdatum between Dim.ValidFrom and Dim.ValidUntil
Now in SSIS I want to handle the whole thing in the data flow without using a staging table:
- Using Lookups: I would have to pass the date column for each inside the fact table into the lookup. That does not work.
- Using Execute SQL in the data flow: would be very slow, because the statement will be executed for any line in the dataflow
Any ideas?
Best regards,
Stefoon
Hi,
I'm trying to create a DM model using TS algorithm, to predict sales for different products and channels but I can only get it to work using one of those two "dimensions" or columns the other one is ignored (This is, my fact table contains a key for time, a key for channel a key for product and the metrics and the model only seems to allow working with time, the metrics and only one of the other dimensions product or channel ..) Am I missing something?
Thanks
I want to include the name of the user whom so ever has changed the record.
I want to insert the name of the user in the column.
How to grab the name of the user from the action...?
Thanks,

My DB saves it's data into a table at the end of each day like:
'e4_event_20140530' where the last bit changes according to the date. So 30th May 2014 in this case.
What I am trying to do is query the last 24 hours. I know i can grab from 2 tables and do a 'between' with times but it means having to change table name and times in the query every time i run it. I'd just like to run it and for it to just fetch the last 24 hours at any point in time.
My DB outputs time like '2014-05-30 08:54:23'
Hello again,
I'm going through my tables and rewriting them so that I can create relationship-based constraints and create foreign keys among my tables. I didn't have a problem with a few of the tables but I seem to have come across a slightly confusing hiccup.
Here's the query for my Classes table:
Code:
CREATE TABLE Classes
(
class_id
INT
IDENTITY
PRIMARY KEY
NOT NULL,
teacher_id
INT
NOT NULL,
class_title
VARCHAR(50)
NOT NULL,
class_grade
SMALLINT
NOT NULL
DEFAULT 6,
class_tardies
SMALLINT
NOT NULL
DEFAULT 0,
class_absences
SMALLINT
NOT NULL
DEFAULT 0,
CONSTRAINT Teacher_instructs_ClassFKIndex1 FOREIGN KEY (teacher_id)
REFERENCES Users (user_id)
)
This statement runs without problems and I Create the relationship with my Users table just fine, having renamed it to teacher_id. I have a 1:n relationship between users and tables AND an n:m relationship because a user can be a student or a teacher, the difference is one field, user_type, which denotes what type of user a person is. In any case, the relationship that's 1:n from users to classes is that of the teacher instructing the class. The problem exists when I run my query for the intermediary table between the class and the gradebook:
Code:
CREATE TABLE Classes_have_Grades
(
class_id
INT
PRIMARY KEY
NOT NULL,
teacher_id
INT
NOT NULL,
grade_id
INT
NOT NULL,
CONSTRAINT Grades_for_ClassesFKIndex1 FOREIGN KEY (grade_id)
REFERENCES Grades (grade_id),
CONSTRAINT Classes_have_gradesFKIndex2 FOREIGN KEY (class_id, teacher_id)
REFERENCES Classes (class_id, teacher_id)
)
Query Analyzer spits out: Quote: Originally Posted by Query Analyzer There are no primary or candidate keys in the referenced table 'Classes' that match the referencing column list in the foreign key 'Classes_have_gradesFKIndex2'. Now, I know in SQL Server 2000 you can only have one primary key. Does that mean I can have a multi-columned Primary key (which is in fact what I would like) or does that mean that just one field can be a primary key and that a table can have only the one primary key?
In addition, what is a "candidate" key? Will making the other fields "Candidate" keys solve my problem?
Thank you for your assistance.
i have 2 tables right now, po and notes...
the notes table contain the note_id and notetext, so example of a row would be:
1 this is the note for the first row
2 this is the note for computer parts
etc..
the po table has item info, description, po_id, and note_id, heres an example:
po_id item desc note_id
1 215-33 computer parts 2
the problem is, is there a way where say i insert the note row into the notes table first and then get the note_id of that, so that i can then insert the row into the po table which includes the note_id from the notes table?
would i have to use two separate inserts or can i use one? i was going to just insert the notes row first, and then use a query using the LIKE() function on the note text to get the note_id, but some notes may be the same as others, so the note_id wouldn't be the correct one :( and i think just getting the last row of the notes table would be bad too incase someone happens to insert a row into that table at the same time
any ideas please?
thanks!
Hi all,Anyone can show me how can I catch the 'Print' statement that I have defined in my store procedure using SQL server 2000 DB on the .aspx page? ( I am using ASP.NET 1.0)My store procedure as follow:CREATE PROC NewAcctType(@acctType VARCHAR(20))ASBEGIN --checks if the new account type is already exist IF EXISTS (SELECT * FROM AcctTypeCatalog WHERE acctType = @acctType) BEGIN PRINT 'The account type is already exist' RETURN END
BEGIN TRANSACTION INSERT INTO AcctTypeCatalog (acctType) VALUES (@acctType)
--if there is an error on the insertion, rolls back the transaction; otherwise, commits the transaction IF @@error <> 0 OR @@rowcount <> 1 BEGIN ROLLBACK TRANSACTION PRINT 'Insertion failure on AcctTypeCatalog table.' RETURN END ELSE BEGIN COMMIT TRANSACTION ENDENDThanks for all your replies
Hi,
I have 2 fact tables and 2 dimensions (one of them is time).
fact1 ---- pk-fk ------ fact1-details-table
(date) |
| Dimension.
|
TimeDim
Is there a way to define measure group on fact1-details-table using TimeDim. Date info is only in fact1 table and not in details table.
Is namedquery joining the 2 fact tables the best solution in this case? There is so much redundancy using one fact table, so underlying sqldb uses 2 tables.
Thanks,
Chandra.
I am modelling two fact tables of Actuals and Budget which are at different granularity, Actuals are at day, customer and product sub category level. Budgets are at month, Region and Product category level.
Month, Region and Product Category is present in Date, Region and Product Category dimension respectively. I have only three dimensions as Customer, Product and Date. Linking those dimensions to Actual Fact table is not an issue, what is the best way and options are there to link budget fact table to those three dimensions.
Hi, all experts here,
Do we always have to use SCD component for the loading of data into data warehouse to handle changes of rows?
I am looking forward to hearing from you and thank you very much in advance for your help.

Hi,
I accidentally deleted a table in my local server. How can I get back the table? I did not do it as a transaction!
Thanks in Advance
what the best practice is for creating indexes on columns that are foreign keys to the primary keys of other tables. For example:
[Schools] [Students]
---------------- -----------------
| SchoolId PK|<-. | StudentId PK|
| SchoolName | '--| SchoolId |
---------------- | StudentName |
-----------------
The foreign key above is as:
ALTER TABLE [Students] WITH CHECK ADD CONSTRAINT [FK_Students_Schools]
FOREIGN KEY([SchoolId]) REFERENCES [Schools] ([SchoolId])
What kind of index would ensure best performance for INSERTs/UPDATEs, so that SQL Server can most efficiently check the FK constraints? Would it be simply:
CREATE INDEX IX_Students_SchlId ON Students (SchoolId)
Or
CREATE INDEX IX_Students_SchlId ON Students (SchoolId, StudentId)
In other words, what's best practice for adding an index which best supports a Foreign Key constraint?
I have one control table to store all related table name
Table ID TableName
1 TableA
2 TableB
In Table A:
RecordID Value
1 1
2 2
3 3
In Table B:
RecordID Value
1 1
2 2
3 3
How can I get the result by select the Table list first and then combine the data in table A and table B?
Thank you!
I have a query which is quite complex. It's based on a set of data ina complex view which takes the data from several tables.In this complex query, if I allow the various parts of the query towork on the results of the view (MISView), it can take 15 minutes torun (eek !), however, if I create a temporary table with the data fromthe view and then use that for the remainder of the query, it runs inapprox 20 seconds.Now, I have examined the execution plan (my new favourite toy) andthere is a difference (as expected). However when looking at the partof the query that takes up most of the time, it shows that it bringsback 109,645,866 records from a table (Credit) that contains 13,002records. This table is one that is referenced in the view (MISView)which contains 13,653 records and does get some of it's data from thetable which is scanned (Credit).For the record, we don't have any tables with over 100,000 records in,so 109 million rows is going some for us. The part of the query thatruns slow does reference another copy of itself but this is necessaryfor the equation that is being run.Now I'm OK with why it's doing the table scan, but why does it bringback substantially more data than is in the table ? Is it somemultiple of the number of records that it's trying to work out. Iassume it tries to run a seperate plan for the view as part of it'sprocess.Ideally, I'm still going to go down the route of the temporary table,but I would like to understand more about what it does first as Idon't like leaving things unanswered.Any help would be appreciated.

Pls let me know How I generate script for All primary keys and foreign keys in a table. Thereafter that can be used to add primary keys and foreign keys in another databse with same structure.
Also how I script default and other constraints of a table?
There is itemlookup table, which stores item number and itemdescription. Also there is a child table, pricehistory, of theitemlookup table, which stores different prices and different dateranges. So it is one-to-many relationship. (Price can be stored morethan one with a different date range)And there is another table RequestItem that stores the foreign key ofthe itemlookup table to show the information of the itemlookup table.Then how do I know later which date range of the price was stored inthe RequestItem table? Since I only keep the foreign key of theitemlookup table, it will be impossible to keep track of the row of thepricehistory table if there are more than one data existed in thepricehistory table.Will it be a valid table structure to create a column for the foreignkey of the pricehistory in RequestItem table or any other ways tohandle this issue?
View 1 Replies View RelatedHello all,I got a chance to peak into a database system. Part of its design israther unfamiliar to me. When I look at the diagram generated by SQLServer, there are many floating tables. Eventually it turns out thatthese many floating tables are actually not floating. Their tablenames relate to fields (as TableID) in other tables. In this case,you can get a handle to one of such tables by search TableID columnsin other tables.To be more specific, the database is a microarray database implementedin SQL Server 2000. They have a table called MICROARRAYS. In thistable, there is a column called table_id. These table_ids are in facttable names of a bunch of other tables.My questions are1) Is this good relational design?2) How well is this kind of design supported in SQL Server?3) Are there better alternatives?Any other comment or link to helpful resources will also beappreciated.Thanks,Eric Wu

I'm using SqlDatasource when the update process is on a primary key, how do you cascade the changes to other tables?
Also when deleting does the cascade deletes the row from another table or only sets the primary key to NULL?
I have two tables as below. I want to update a quote and change the item for which it is for. So I want to do an update statement to change the cat_ref that the quote is for. However, when I do this I get a foreign key conflict with cat_ref in the item table. How do I get around this? Thanks
Code:
CREATE TABLE Item (
cat_ref VARCHAR(5)PRIMARY KEY,
descrip VARCHAR(50),
date_added SMALLDATETIME,
cat_type VARCHAR(20))
CREATE TABLE has_quote (
quote_id INT IDENTITY (1,1) PRIMARY KEY,
date_last_pricecheck SMALLDATETIME,
cat_ref VARCHAR(5)FOREIGN KEY
REFERENCES Item(cat_ref)
ON DELETE CASCADE,
first_name VARCHAR(10),
surname VARCHAR(10),
FOREIGN KEY (first_name, surname)
REFERENCES Customer(first_name, surname)
ON DELETE CASCADE
ON UPDATE CASCADE)

View 1 Replies View RelatedI have two tables:
tbl_Vehicles (primary table)
tbl_DealerFeed_temp (temporary table)
I load values from a TXT file into the temporary table. From there, I figure out which records are new and need to be added to the primary table, and which records are duplicates, and need to a) update the primary table and b) be deleted from the temporary table.Basically, I need to write a SQL statement to grab the records that exist in BOTH tables based upon two primary criteria:
d_id in temporary table = d_id in primary table
df_t_v_stock_number in temporary table = v_stock_number in primary table
There are several fields that must be updated if the d_id and v_stock_number match:
v_price
v_internet_price
v_other_price
v_mileage
Hello,
I have a very elementary question on table design. This screenshot (which is part of a larger diagram) sets the context of the question.
There are two distinct groups of products with different attributes, hence two separate tables: Products_A and Products_B.
There's a third table that keeps track of daily production (DailyProduction), which must accept items from either product table. Now, my question is: How do I relate these two tables to "DailyProduction" ? If I place a double-constraint with two foreign keys, then I get an error whenever I attempt to insert a record in DailyProduction. For example, if the new item is of "Products_A" type, then the error message from SSMS is:
No row was updated.
The data in row 1 was not committed.
Error Source: .Net SqlClient Data Provider.
Error Message: The INSERT statement conflicted with the FOREIGN KEY constraint "FK_DailyProduction_Products_B". The conflict occurred in database "MyDatabase", table "dbo.Products_B", column 'ProductB_ID'.
The statement has been terminated.
Correct the errors and retry or press ESC to cancel the change(s).
It's clear that the error message makes sense as SQL is trying to apply BOTH constraints. It's one AND the other, not one OR the other. Now, how do I remedy this ? What would be the most appropriate way to relate the three tables ?
Thanks.
Fernando

View 6 Replies View Relatedi'm using sql express, management studio express and a visual web developer starter kit.
i have 4 tables: items; categories; categorization; old_items
the old_items table has both the item id and category fields in it, the new db has them separated: items.id; categories.id; categorization.itemId, categorizaton.parentCategoryId, both of which are foreign keys.
i need to get the old_item.id and old_item.category values into the new categorization table but it keeps choking on the foreign keys and i can't get past it. as far as i've been able to figure out so far, i need to turn off the foreign keys to do the insert but i'm not sure and i haven't been able to find any sql query examples that demonstrate it or explain it well enough for my n00b self.
i've read http://msdn.microsoft.com/en-us/library/10cetyt6.aspx, "How to: Disable Foreign Key Constraints with INSERT and UPDATE Statements" but i don't get how that affects it, it seems like one of the other options would actually disable them.
can anyone help? i've been trying all the permutations of queries i can think of and not getting it.
thanks.
