Here's another one of my bitchfest about stuff which annoy the *** out of me in SSIS (and no such problems in DTS):
Do you ever wonder how easy it was to set up text file to db transform in DTS - I had no problems at all. In SSIS - 1 spent half a day trying to figure out how to get proper column data types for text file - OF Course MS was brilliant enough to add "Suggest Types" feature to text file connection manager - BUT guess what - it sample ONLY 1000 rows - so I tried to change that number to 50000 and clicked ok - BUT ms changed it to 1000 without me noticing it - SO NO WONDER later on some of datatypes did not match. And boy what a fun it is to change the source columns after you have created a few transforms.
This s**hit just breaks... So a word about Derived Columns - pretty useful feature heh? ITs not f***ing useful if it DELETES SOME of the Code itself after there have been changes in dataflow. I cant say how pissed off im about that SSIS went ahead and deleted columns from flow & messed up derived columns just because the lineageIDs dont match.
Meta-data - it would be useful if you could change it and refresh it - im just sick and tired of it that it shows warnings and errors when there's nothing wrong - so after a change i need to doubleclick all my transforms so that those red & yellow boxes would disappear.
Oh and y I passionately dislike Derived columns - so you create new fields based on some data - you do some stuff - combine multiple columns to one, but you have no way saying remove the columns from the pipeline. Y you need it - well if you have 50K + rows with 30+ columns then its EXTRA useless memory overhead for your package.
Hopefully one day I will understand how SSIS works (not an ez task I say) - I might be able to spend more time on development and less time on my bitchfest - UNTIL then --> Another Day - Another Hassle with SSIS
i have a table called download_transactions which contains wallpaper and video downloads. videos have a download_type of 110 and wallpapers 104. i need to pull out a count of these transactions where download_type is 110 and 104. so one results column is count of 110 downloads and the other column is count of 104. thing is, one canned do; .. where download_type 110 And 104 where download_type in (110, 104) because this just confuses SQLserver. two conditionals. how to do this, any ideas. must i use a cursor to go through results once for 110, then again for 104?
at the moment, i select to pull out the count, and it gives two rows for each download type e.g. clientID date count 50015 2007-03-06 00:00:00.000922 50015 2007-03-06 00:00:00.0001430 50020 2007-03-06 00:00:00.000486 50020 2007-03-06 00:00:00.000872
two rows for each clientID, one is count of 110, and one is count of 104. i just need the 2nd row count to be in a 4th column next, like this:
clientID date 104/count 110/count 50015 2007-03-06 00:00:00.000922 1430
this is the sql i am using:
declare @start_date datetime declare @end_date datetime declare @start_timeshift int declare @end_timeshift int declare @client_id int
I'm trying to write a query that concatenates multiple records into onederived column. Let's say I have an author (Joe Writer) who has writtenthree books (Book 1, Book2 and Book 3). The author is in tblAuthors, hisbooks are in the tblBooks and they are joined by the AuthorID field(number). If I use a simple select query to give me the author name and thetitle, I will get three records, one for each book written.What I want is to have all three books combined into one derived column. Soif I do the select statement, I will get one column with the author name,and the second column will put together all three names of the bookseparated by a column. So it will look like:Author TitleJoe Writer Book 1, Book 2, Book 3,Rather than having it appear as 3 records:Joe Writer Book 1Joe Writer Book 2Joe Writer Book 3Could someone help me with the SQL involved in this?Thanks for the help.Cheers,Mike
Hi I'm updating an old Access application to SQL Server and am currently trying to decipher one of the reports on the old application. It appears to be evaluating a derived column from one query (qryStudentSuspGroup.Suspension) in the Select statement of another. I have tried to put the query that creates the derived column in as a nested query into the other query but can't get it to work. This is all a bit beyond my rudimentary SQL skills! Any help would be greatly appreciated!
The original Access SQL appears below:
SELECT [Enter the academic year (4 digits)] AS [input], ResearchStudent.Department, ResearchStudent.DateAwarded, ResearchStudent.StudentNumber, Person.Forenames AS fore, Person.Surname AS Sur, ResearchStudent.Mode, ResearchStudent.RegistrationDate, StudentExamination.Decision, IIf(([Suspension]) Is Null Or [Suspension]=0,([DateAwarded]-[RegistrationDate])/365,(([DateAwarded]-[RegistrationDate])-([Suspension]))/365) AS CompDate, ResearchStudent.EnrollmentCategory, qryStudentSuspGroup.Suspension FROM ((ResearchStudent LEFT JOIN Person ON ResearchStudent.ResearchStudentID = Person.PersonID) LEFT JOIN qryStudentSuspGroup ON ResearchStudent.ResearchStudentID = qryStudentSuspGroup.ResearchStudentID) LEFT JOIN StudentExamination ON ResearchStudent.ResearchStudentID = StudentExamination.ResearchStudentID WHERE (((Year([DateAwarded]))>=[Enter the academic year (4 digits)] And (Year([DateAwarded]))<=([Enter the academic year (4 digits)]+1)) AND ((IIf(Year([DateAwarded])=[Enter the academic year (4 digits)],Month([DateAwarded])>8,Month([DateAwarded])<9))<>False)) ORDER BY ResearchStudent.Department, ResearchStudent.Mode, ([DateAwarded]-[RegistrationDate])/365
I have seen it happen frequently that I type in a perfectly valid SSIS expression (this is easy for me since I am an old hand at C++/C/C#) in a row in a Derived Column transformation, and it turns red. Or sometimes, I will have an invalid expression that I correct, but it stays red. Finally I have also seen it happen that I make some change in the data flow pipeline and suddenly a Derived Column transform develops an error. I then go into the Derived Column transform and find that the expression has turned red. So, I literally have to go into the expression in these cases, and make a trivial change to them to get the red error to go away. Alternatively, I can cut the derived column expression text, and then paste it back in and it works (this is most telling.)
So, it seems to me the Derived Column is somehow holding onto some meta data about the Derived Column that is getting out of date (rather than re-evaluating the correctness of the Expression.) One thing I usually can do to repro this at times is to remove a column (that the Derived Column depends upon) from the pipeline and then re-add it. When I go into the Derived Column it will be red, and then like I said I have to tweak the expression to force SSIS to re-evaluate the expression.
I'm sending a lot of columns through my derived column transform, checking for empty strings from a flat file - I was wondering is there a way that I could "script out" all the transforms instead of enduring this click hell that I'm stuck in inside the derived column transformation editor. I've got probably 100+ columns to configure with the following sort of transform....
Basically - if the string is empty, then throw Null in the data stream. I'm about a third the way through but it would really be nice if there was a quicker way. Even with the most efficient copying & pasting & keyboard shortcuts, it's still painful.
Is it possible to do pattern matching against a string using FINDSTRING or similar in a derived column expression without recourse to including 3rd party regexp style plugins?
I want to seach for a reference in a string which will have the format ANNNNNAAA ie. an alpha with a certain value followed by 5 digits followed by three alphas with specific values.
I have a lot of different data flows that need "Derived Column". There are maybe only 5 different such "Derived Column" but they appear many times. Is there a way to eliminate all that double work? It should be something that does not take me more time to do than just duplicating all the "Derived Columns".
In my working existing package I am adding a derived column as date and datatype as DT_DBTIMESTAMP and my destination data type is datetime. when I try to union these records through an "Union ALL" component its not allowing me to map this column and throws error as "outputcolumnlineageid " and defines the error as metadata for source and destination are not matching. I checked the metadata and they are DT_DBTIMESTAMP, Am I missing something? please advice.
Trying to setup a derived column to use an expression stored in a package variable. But it seems that variables are always evaluated as text...I need it to evaluate as a Columname sometimes.
Example: On an ETL of Products I want a new derived column that uses two other columns.
I can hardcode an expression of ProductID + " - " + ProductName and that results in dynamic output. But now I want to use that as an expression stored in a variable so I can change it when needed.
So I make that expression = @[User::Variable] and stuff into @variable ( a string param) : ProductID + " - " + ProductName My output is the literal "ProductID + " - " + ProductName", and not the actual ID's and Names
I've tried with/without brackets, quotes and braces but no change.
Any way I can get the pieces in that variable expression to evaluate as column names?
I have 3 different companies that share the same ticket_types(CRMS System). I need to display the Ticket Types and the 3 company's Ticket Count:
Ticket Type | Company A Count | Company B Count | Company C Count
I can get the information individually for each company, but if a company doesn't have a ticket in one of the ticket_types, then it isn't displayed in a row. So, I tried to write the following, which isn't pulling back any data.
DECLARE @startdate date = '20150306' DECLARE @enddate date = '20151031' DECLARE @AcctGrp varchar(20) = '111' ;WITH TType AS ( SELECT ctp.description as TicketType
[Code] .....
If I run each SELECT individually from above (excluding the last SELECT), it works and I get the following:
TicketType AR Request Credit Availability/Rush Cancel Order Credit Card Payment Expedite Order Freight Quote
[Code] ...
How to get the query results? Am I even close to getting it right?
how to declare multiple derived columns in SSIS Derived Column Task in one attempt.as i have around 150 columns coming from Flat file. I had created the required Expression in Excel and now i want add those in derived column task but its allowing only 1 expression at a time.
Case: Exporting Report to PDF/Printing/TIFF Report: Contains 1 table with 19 Columns. 1 column is static, the other 18 are visible at the users descretion. Report when printed/exported to pdf spans 2 pages naturally, 16 on the first page, 3 on the second, and the column widths have been adjusted to provide a perfect page span .
User A elects to hide two of the columns, and show the rest. The report complies and the viewable version is perfect, the excel export is perfect.. the PDF export on the first page causes every fith column, starting with the last column that was hidden to be expanded to take up additional width. On the spanned page, it renders the first column on that page correctly, then there is a white space gap equal to the width of the hidden columns and then the rest of the cells show with the last column expanded to take up the same width that the original 2 columns were going to take up, plus its width.
We have tried several different settings to see if it helps this issue or makes it worse. So far cangrow/canshrink/keep together have made no impact. It is not possible to increase the page size due to limited page size selection availablility for the client. There are far too many combinations of what the user can elect to show or hide to put together different tables to show and hide on the same report to remove this effect.
Any help or suggestion on this issue would be appreciated
Hi, wondering if anyone can help me. I currently have a field that has a date and time in it in the format dd/mm/yyyy hh:mm:ss. Ideally I would like to get rid of the time part of it altogether but for it to still be recognised as a date as opposed to a string. However, I've been told that this is not possible in 2005, is this true? If this is the case, what would be the best way to set the time to 00:00:00 after the date for all records on that field?
Hi. We have to create an export from our system to be imported into another system. To get the data out we need to create some SQl but we're struggling a bit.

I am trying to transfer data from SQL Server 2005 table to another SQL Table. In the source table there is a field called Region [nvarchar(max)]. The values for these fields will be like APAC-China, NA-Racine, etc., i.e Region followed by the country name seperated by - symbol. I want the destination tablre with 2 fields Region[nvarchar(max)] and Country [nvarchar(max)]. I am using a Derived Column task to achieve the same.
Can anyone please help me out in doing this data conversion?
Is there a way to group by a derived value? For example, in the query below, is there a way to group the results by the AgeBracket field? I'd like to see adults (0) in one grouping and children (1) in the other.
SELECT AgeBracket = CASE WHEN dbo.GetAge(DOB, GETDATE()) > 18 THEN 0 ELSE 1 END, COUNT(*) FROM tableX
I am doing a task which will get all data based on several base and crosswork tables. I used stored procedure to get the data, but the next step will be using derived column to massaging data, and to load to the destination database. Is there a way to do that since I must generate data on the fly?

I am trying to create a derived column from two separate fields. One is a date field in format of 2008-03-01 and one is a time field. In DTS I use to have something like this:
I am trying to figure out how to do this in SSIS. I know I have to use a dervived column but can't seem to come up with the correct syntax. Any help would be apprecaited. thanks.
i have a column in my table that will store the sum of 3 other column, e.g the data in total_book column will be equal to the sum of the number in the romance, fiction and thriller column. how do i do this?
Hi, I have built a database for a university project, but am having trouble with the SQL syntax for inserting derived data from a calculation into a table. At present my SQL is; INSERT INTO MemberPayment (TotalCharge) VALUES ( [Total] ) SELECT ((MileageHistory.MileageUrban * Vehicle.EmissionsPerGramUrban) * 0.05) + ((MileageHistory.MileageCountry * Vehicle.EmissionsPerGramUrban) * 0.05) AS 'Total' FROM [NeuCar].[dbo].[MileageHistory] JOIN [NeuCar].[dbo].[Vehicle] ON MileageHistory.Registration = Vehicle.Registration JOIN [NeuCar].[dbo].[Member] ON Vehicle.UserName = Member.UserName WHERE Member.UserName = 'wenger1' AND (MileageHistory.[Date] >= CURRENT_TIMESTAMP - 30); Would anybody be able to point out where I am going wrong? I would very much appreciate any advice, Kind regards, Chima
I have a quizzing application where users log in, answer questions, and are ranked relative to each other. For this final ranking, I calculate their score using this formula -
SELECT TOP 50 username, (sum(correct) * 150 / count(1) + count(1)) AS score, count(1) as totalq FROM questionsstats GROUP BY username ORDER BY score DESC
This works just fine.
However, on top of this I need to put an additional restriction that only users who have at least answered 20 questions be counted in. How can I do this? Adding a simple 'WHERE totalq > 20' does not work. I get the error "Invalid column name 'totalq'.".
I got an error as follows: Derived table 'A' is not updatable because a column of the derived table is derived or constant. when I tried to run this query: update A set MonthsUnbilled =99999888 FROM (select MonthsUnbilled from dbo.vw_MasterView WHERE (RecordID =8377396)) A This is a simplified query in order to pinpoint the culprit. I know I don't need to use a derived table if the real query is this simple.
