Need Alternative To PATINDEX In Derived Column Transform
Oct 30, 2007
Hello,
I understand that it is not possible to use PATINDEX in a Derived Column transform. I'm trying to eliminate leading zeros from a column where the string is always 14 characters long, but the first non zero character could occur any number of characters from the left of the string. The following achieves what I need:
substring([Account No w/0s], patindex('%[^0]%', [Account No w/0s]), 14) AS ExtractedAcctNo
Does anyone happen to know how I might express this differently in a Derived Column transform? Should I consider a calling a function through an OLE DB Command transform on each row instead? Maybe I should have a SQL Task that runs an UPDATE statement against the column.
HI, I was wondering if there is a possibility to use a confitional if like this:
IF(ISNULL(mycolumn value, "new value if null", mycolumnvalue)
into a derived column transform to infer a value to a null column value. I do know I can do it using a script component by it would be simpler to do by using an expression.
When data is imported from our legacy system, the same functions need to be applied to several columns on different tables. I want to build a kind of "Function Library", so that the functions I define can be re-used for columns in several packages.
The "Derived Column" transform seems ideal, if only I could add my list of user-defined functions to it. Basically I want to inherit from it, and add my own list of functions for the users to select.
Is this possible ?
What other approaches could I take to building about 30 re-usable functions?
i have too many DTS packages to migrate to SSIS, and while examining a DTS package in BIDS (converted with the migration utility) i tried to edit the resulting migrated package, which opened the DTS interface with the two connection icons joined by the big fat arrow with a gear on it...not exactly what i had in mind, iow, it looks like SSIS on the outside, but its still DTS on the inside. So I stripped out a series of components from a more complex package hoping that simplifying it would reveal the contents of old DTS Transformations tab at least partially set up in a Derived Column transformation. Can i get there from here, or must i recreate every stinking definition in a derived column manually from the ground up? thanks very much for your help
W2k3 server, SQL 2005. @@version = Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86) Standard Edition on Windows NT 5.2 (Build 3790: Service Pack 1)
I have my first SSIS package almost working, but I'm having an odd problem and can't find any information to help resolve it.
I'm importing from a flat file (csv) to an existing table (append). I've got a Derived Column transformation in the middle to do some data cleanup. It's all working except for one little problem...
One of the transformations is 'REPLACE([Column 3],"^","; ")', output to a new column. (The input file has a field that uses carets as delimiters between an unknown number of items; I'm changing that to semicolons for easier reading.) Not all rows have data in this column, some will have one item, some will have multiple items.
The REPLACE works except that it fills in repeated data for all the blank rows.
Example:
Incoming data is:
1 Smith,Jane^Jones,Jane
2 Brown,John
3
4 Adams,James^Adams,Jim
5
6 White,Debra
Data inserted into the table is:
1 Smith,Jane; Jones,Jane
2 Brown,John
3 Brown,John
4 Adams,James; Adams,Jim
5 Adams,James; Adams,Jim
6 White,Debra
I've tried to use a Conditional to skip the empty rows, but I can't get that working at all (get syntax errors no matter what I put in).
Any suggestions on how to fix this would be most appreciated!
I have an application that has two different database backends, one is SQL Server Compact Edition and the other is SQL Server. The reason is because the application may run at home on one of our sales agent's computers or here in the office.
I have a query that uses a derived table and works just fine in SQL Server, however when I run it in the compact edtion (having the exact same table structures) it will not run. My question is...does the Compact Edtion or the Mobile Edition allow derived tables. If not is there a way to work around this? I will happily give an example if it will help.
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.
I have a excel file which has a column called "Code" and their values are A,B,C,D,E,F,G,H. I want to create a new column called "status" based on the values of "Code".
Code:
A B C D E F G H
If A,C,E,G then "status" = "Active" else if B,D,F,H then "Status" = "Inactive". I like to do it using "Derived Column".
I am unfortunately lumered with a table I cannot edit that stores a division 2 characters along with boolean fields '0506', '0607', '0708' ... (academic years) to represent if that particular division is active in the current academic year. This has made me have to resort to dynamic sql within a stored procedure to input the appropriate field names.
Is there a better way to do it, it's not mission critical to make it not use dynamic sql but I would prefer not to.
Hi, I have dates in "mmddyy" format coming from the sources and they are older dates of mid 80s like 082580 for instance.
When I cast it this way (DT_DBTIMESTAMP) Source_Date , It says ok but throws a runtime error.
When I hardcode a date in same format, (DT_DBTIMESTAMP) "082580" , It becomes red (an indication of syntax error) . Please note that we use double quotes in expressions in Derived Column Transformation; So an anticipation that using double quotes over single ones would be the syntax problem would be wrong.
Hey all - got a problem that seems like it would be simple (and probably is : )
I'm importing a csv file into a SQL 2005 table and would like to add 2 columns that exist in the table but not in the csv file. I need these 2 columns to contain the current month and year (columns are named CM and CY respectively). How do I go about adding this data to each row during the transformation? A derived column task? Script task? None of these seem to be able to do this for me.
Here's a portion of the transformation script I was using to accomplish this when we were using SQL 2000 DTS jobs:
' Copy each source column to the destination column Function Main() DTSDestination("CM") = Month(Now) DTSDestination("CY") = Year(Now) DTSDestination("Comments") = DTSSource("Col031") DTSDestination("Manufacturer") = DTSSource("Col030") DTSDestination("Model") = DTSSource("Col029") DTSDestination("Last Check-in Date") = DTSSource("Col028") Main = DTSTransformStat_OK End Function *********************************************************** Hopefully this question isnt answered somewhere else, but I did a quick search and came up with nothing. I've actually tried to utilize the script component and the "Row" object, but the only properties I'm given with that are the ones from the source data.
I want to have an other employee table named employee_modified
Empno empname salary commission derived_column1(salary+commission) derived_column2(derived_column1 + xxxx) and so on derive other columns based on the earlier derived columns)
Is that possible to do it.. or am I doing something wrong.
I am working on SSRS 2008, I need to change background color of alternative columns. We can change simply if it is a textbox column but my columns all are in checkbox () based one expressions and I didn't see any background color option In properties for this check box column(please see the images below), is there any way to change background color for alternative columns?I need like this
Hi, how are you? I'm having a problem and I don't know if it can be solved with a derived column expression. This is the problem:
We are looking data in a a sql database.
We are writting the SQL result in a flat file.
We need to transform data in one of the columns.
For example: we can have 3 digits as value in a column but that column must be 10 digit length. So we have to complete all the missing digits with a zero. So, that column will have the original 3 digits and 7 zeros. How we can do that tranformation? We must do it from de the flat file or it can be a previous step? Thanks for any help you can give me. Regards,
Is there a transform available which allows you to specify two different tables (same primary key) and compare columns (you identify which column(s) values need to be compared in the transform) between those two tables?
Hi all, I'm new at this SSIS but have been able to successfully create some simple packages. My situation is that at work we use a column to describe a status of applications. However, this makes for hellacious query because some of those statuses inherintly were one or more statuses previously. Example Admit = Admit Accept = Admit then Accept Withdraw Accept = Admit, Accept, then Withdraw Decline = Admit then Decline As you can see inherintly those were all admits at one point. So what I'd like to do is instead of having long queries for example to get all my "Admits", I'd rather query another table that has the following columns as bits: Admit Accept Withdraw That way I can query the admit column and get all my admits. How can I use SSIS to transform my "Decision" column into those bit columns? Thanks for any help or suggestions you have.
I have a table with a BLOB column, and I need to populate this table including the BLOB column (image type in the database).
What I have done is:
1. use a flat file transform to read a .csv file which specifies the names of the files that store the binary contents for the BLOB column for each row.
2. use an Import Column Transform to read the binary files.
3. use an OLE DB Dest transform to dump the data into my destination table.
I got the error saying:
Error: 0xC02090BB at XXXX, Import Column [1]: Opening the file ".diagram1.bin" for reading failed. The file was not found.
I guess this is because my file "diagram1.bin" is not in the current path? (The current path can be found by "System.IO.Directory.GetCurrentDirectory() call, in my case it is "c:program filesmicrosoft visual studio 0common7IDE".)
My question is: how to determine the directory path information of the package I am running?
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?
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?
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.
In a Derived Column data flow transformation, why can't I refer to a derived column (added in that same transformation) in the expression for another derived column? It seems I am forced to chain 2 DC data flows, just to do something as conceptually simple as:
a = x + y; b = a²
On a related note: Can I define a variable that is scoped to each row? Can I bind a variable in an expression to avoid creating a new row, e.g.
Would anyone happen to have any pointers or know of any good code examples to either programmatically change the type of an input column when it is passed through the component, or add a new column to the output? I am extracting data from an Oracle database which is in Julian date format (represented within SSIS as a DT_NUMERIC column) and I need to to either transform the input column holding it into a date column, or to dynamically add a new output column holding the transformed data.
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'.".
1. In a if else expression if condition is false how do you keep the value of the source column eg: Name == "" ? "Unknown" : Name Above will change all the non blank values to Name and not the actual value in the Name Column eg. John
2. I have a column (unicode string)that stores date and time (The source is flat file) Is it possible to write expression to select the 1st day of month based on that date, and use this derived column as input to a table with a datetime field.
Hello, first time here, first time messing with SQL.
When creating a table in SQLServer2005 can you specify a column to be for a derived attribute. example a column monthlysalary and create a column that is a derived attribute - yearly salary. Is this done when creating the table and how is the syntax ?
