Integration Services :: SSIS - Derived Column That Transforms Case Statement
May 18, 2015
Derived column that transforms a CASE statement?
CASE
WHEN [MAIN_GAME] IS NULL AND combo.[CAT_PRODUCT] ='25' THEN 'Standalone'
WHEN [MAIN_GAME] IS NULL AND combo.[CAT_PRODUCT] <> '25' THEN 'No main game'
ELSE LOWER(prod.[TX_PRODUCT_NAME])
END AS [TX_MAIN_GAME]
I have an SSIS package in which I need to include a derived column. I've done derived columns a ton when there is just one condition being "tested". In this case there are two. I have the following update statement for a table I'm inserting data into:
UPDATE STAGING_DIM_AR_INVOICE SET SC_CODE = ( CASE WHEN REC_TYPE = 'P' AND SC_CODE IS NULL THEN 'ag' WHEN REC_TYPE = 'I' AND SC_CODE IS NULL THEN 'OL'
[Code] ....
I'd like to be able to address this case on the load itself. I've used CONDITIONAL before, but not sure how that would work in this case. I'm trying to keep it as "simple" as possible.
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 have 10 columns i.e from Segment1 to Segment10. I need to concatenate it with ".". All 10 segments can be null. If any of the segment is null i do not want to show ".". This is the expression I am using
I have the following 2 fields that are sourced from an Excel spreadsheet
DocNumber - a 10 digit number PostingRow - a number between 1 and 999
I would like to produce a new column that is a concatenation of these two fields, but the PostingRow needs to be a 3 digit number eg. 1000256153-001 ....
Is it possible to access a Derrvied Column from an OLE-DB Command? I have to Update a Table with a join and i need from the source Table columns which have to be pivoted before i can use it in the update Command.
I am using a OLE DB source task and i want to setup a parameter in the select statement. Is this possible and how would this be done. I know you can pass a parameter in the where clause like:
select id, lname, fname, startDate, endDate from Employee where id = ?
How would i set startDate and endDate as parameters as i would like to be able to change these parameters when running the package. I would like to set dates in the select statement as parameters like how you would in the where clause.
Select id, lname, fname, ? startDate, ? endDate, from employee where id = ?
I would like to be able to change these dates without having to go in to the package and hard code it back in there and then deploy.
The package uses a OLE DB source to Flatfile Destination.
we have a table with xml column. This column has a large xml data . I am trying to use ssis to import xml from sql column (table a) to destination (another table).
steps which i did in ssis:
1. execute sql task:
fetch the xml column by query and store "full result set" into an object variable.
2. foreach loop:
select Ado enumerator option and select variable which has reset set of execute sql task. In variable mapping selected a new variable of type string.
when I run package I get below error:
"Error: ForEach Variable Mapping number 1 to variable "User::variable" cannot be applied".
My Requirement IS : 1<sup>st</sup>run: if the record does not exist in the table insert the record (file_name, last_modified_file_date) and create a copy in the archive folder with file_name_currentdate.csv
Daily run: retrieve the last_modified_file_date from the input file and check if the retrieved date is greater than the last_modified_file_date in the table:
If true: create a copy of the input file in the archive folder and update the last_modified_file_date in the table with the retrieved date
If false don’t do nothing because the file has been archived in one of the previous runs.I have already retrieving the modified date and File Nae iserting into Filename Table: (That table has 2 columns which are FileName and FileDate) so In script task everytime the variable getting Modified date(retrieve the last_modified_file_date from the input file). How I can Compre the existing table record and variable. I have already imported the all Filenames and Modified into table like below.
I have some source files is there today it will have 4 columns..Tomorrow it will have 10 columns...my package is dynamically load the data to destination table..How we have do it in Using script task...
How do I pass a single column of values from a successful merge join to an EXECUTE SQL statement so it can be used with an "IN" criteria of the WHERE clause? Here's an example of my update statement with two random key values:
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK IN ("XYZ123", "DEF890")
Is this even possible in SSIS, or am I better off using a loop and running the update EXECUTE SQL Statement for each individual key value, as in the following example?
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "XYZ123" UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "DEF890"
I have a file with a header row which contains the date of the file and under that all the columns without a header.
In SSIS package I skip row and manually name the different columns.
However, I want to use the column in the header row to store the date value in an SSIS variable and use that variable to write it to our staging table. How can I do this when I skip the header row?
Public Class ScriptMain Inherits UserComponent Dim smpid As String Dim Prdt As String Dim rcnt As Int64
[code]...
Using the Vb script above I am expecting to read the first row from a flat file source and transferring the data into two variable using script component.
I get the following errors one after the other:"The collection of variables locked for read and write access is not available outside of PostExecute." "Object reference not set to an instance of an object."
I am a newbie to SSIS and looking for answer to a simple search/replace style question.
I am building a derived column and looking for some expression syntax that can search for several strings in one column and set a value in a new column.
A bit like a case statement:
CASE ProductLine WHEN 'R1' THEN 'Road' WHEN 'M1' THEN 'Mountain' WHEN 'T1' THEN 'Touring' WHEN 'S1' THEN 'Other sale items' ELSE 'Not for sale' END,
The twist is that 'R1','M1','T1','S1' could feature anywhere in the string that is ProductLine.
I'm currently loading a package that does a lookup on a column of data type nvarchar(4).The values itself are (A+, A, B+, B, C, D, /). The strange lookup behaviour is happening for each of the cases, so it's not related to a specific value. After trying to put the cache on NO CACHE, the lookup works perfectly. When using the default FULL CACHE the strange behaviour happens. Could it be related to the data type? I have not yet tried to use a CHAR instead of a NVARCHAR but it looks like people have similar issues using CHAR.
I build my SSIS package based on the above file.But now i receive files with different columns order let say
lastName,FirstNamr,Address l1,f1,a1 L2,f2,a2 or Address,FirstName,LastName a1,f1,l1 a2,f2,l2
every time i receive multiple files in different order and i have to remap all my mappings. These are just a few columns and i have like 20 columns and the order can potentially change any time. so every time i have build new packages remap them etc.
through normal c# code it pretty easy. I tried to add script here but the script also needs a source and mapping so there is also a mapping issue. Is there a better way to do this.
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.
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".
TABLE_NAME DESC CODE tab1 table1 A tab1 table1 B tab1 table1 C tab2 table2 D tab2 table2 E tab2 table2 G...
First column values are table names which are already exists in target database. Next two columns[Desc],[Code] data gets populate from CSV file to table.
In this scenario, how to load tab1 data into the same table in destination and so on.
Which way will be more standard to accomplish this task? If its a script task using C#, looking for clear script to identify a value changes in the first column.
I am using SQL Server Data Tools for Visual Studio 2012. I have a very simple SSIS package with a Data Flow task that exports from an OLE DB Source to a tab-delimited unicode Flat File Destination and a Bulk Insert task that loads from the file. Both the Flat File Destination and Bulk Import are using the same code page. The Bulk Insert task is using the wide char format to read from the file. The process works fine with nvarchar and int columns, but when I add a unique identifier column it fails with "type mismatch or invalid character for the specified code page".
I am looking for some syntax to help me with a traditional search/replace style requirement. I am wanting to examine the contents of one column and populate another.
similar to this SQL case statement
CASE ProductLine WHEN 'R1' THEN 'Road' WHEN 'M1' THEN 'Mountain' WHEN 'T1' THEN 'Touring' WHEN 'S2' THEN 'Other sale items' ELSE 'Not for sale' END,
the twist is that R1, M1 etc. can appear anywhere in the ProductLine column.
