Derived Column using Variable

Hi,
I have a requirement to derive month value from the variable.
The variable 'carInputMonth' holds the values 01 or 02 or 03 ...12 based on the input parameter.
My requirement is to load the target file with Month column and the value should be 'Jan', 'Feb',..'Dec'. So I have to derive the month name from month number.. I though to write a case statement in the derived column but it is not working for me. Please
advise.
Thanks.

Hi Amaya14,
Based on your description, you want to create a derived column that corresponding to the values of variable 'carInputMonth': 'Jan', 'Feb',…'Dec' for '01', '02',… '12'.
After testing the issue in my environment, we can use the expression as the derived column in Derived Column Transformation:
@[User::carInputMonth] == "01" ? "Jan" : @[User::carInputMonth] == "02" ? "Feb" : @[User::carInputMonth] == "03" ? "Mar" : @[User::carInputMonth] == "04" ? "Apr" : @[User::carInputMonth] == "05" ? "May" : @[User::carInputMonth] == "06" ? "Jun" : @[User::carInputMonth] == "07" ? "Jul" : @[User::carInputMonth] == "08" ? "Aug" : @[User::carInputMonth] == "09" ? "Sep" : @[User::carInputMonth] == "10" ? "Oct" : @[User::carInputMonth] == "11" ? "Nov" : @[User::carInputMonth] == "12" ? "Dec" : ""
Besides, please verify that the variable name is completely matched. We can drag the correct variable from ‘Variables and Parameters’ group to replace @[User::carInputMonth] in my expression above.
If there are any other questions, please feel free to ask.
Thanks,

Derived column using SQL

Hi All,
I am trying to create ETL using store procedure .
Please helo me to create derived column in qyery
add columns
TimeIn =GETDATE()

Thanks in Advance

Thankx & regards, Vipin jha MCP

Hi Vipin,
Are you use a variable as the OLE DB Source, so the source table is dynamic based on the variable value? If in this scenario, we can use the expression like below for the derived column BBxKey:
@[User::source]=="A"?Substring(Col001,1,7): @[User::source]=="B"?(Substring(Col001,1,7)
+Substring(Col002,1,10)): @[User::source]=="C"?Substring(Col002,1,7): ""

Create 4 Variables & Derived Column in multiple SSISs

Hi
I have 50 SSIS in development & in order to upgrade them I need to create a 3 variables & one derived column in all of them.
I want to know Is there in SSIS, that If I create a one Master SSIS with above changes, & push the same configuration into all my 50 SSISs.
I'm giving you a better look what I exact need..
I want to add above things(3 variables & one derived column with this setting) in my rest packages..
Pls Help..

Hi Visakh16,
Thank you very much for this !
But I need really something more on this.
Can you please put some more light on these things ??
Can we create a 3 variables in all Child SSIS & assign a set values to them in dynamic way ?
If Derived Column Task can be created in Child SSIS through Master SSIS route ? If YES then with setting also ! If NOT, Can we only copy setting from Master SSIS & push
them into 50 SSIS’s If we create Derived Column manually in Child SSIS’s
Please Advice !
1. Yes you can set dynamic values to variables through configurations / parameters (if SSIS 2012)
Configurations itself can be set in multiple ways using
a. XML file
b. SQLServer Table
c. Parent Package (This is what you want as per earlier post)
2. Nope. You need to PHYSICALLY ADD it in each of the child packages
Didnt understand what setting you're doing in derived column. Its expression not a setting so need to be done in each of child pkgs

Best way to derive a "week ending" date using the Derived Column Transformations

Hi, I have an interesting challenge. I am working on creating a BI DB that contains timesheet data. The data contains a column representing the date "worked" ([Date]. Nearly all output reporting is based on a timesheeting week that end on
a Wednesday. My thinking has been to create a derived column "WE" (week ending) that represents the entries of the preceding 6 days.
(Originally I entertained deriving this value view SQL view - however we are talking about a DB that is is a substantial DB (excess of 100M timesheet bookings) and an index on the WE field is warranted) so decided a derived WE column was best approach.
The Date field is represented from a SAP format (German long dated format) - however I cannot use the convert option ;( in the TE.
The Date field is derived via: (DT_DATE)(SUBSTRING([Date ],7,4) + "-" + SUBSTRING([Date ],4,2) + "-" + SUBSTRING([Date ],1,2))
I would welcome some recommendation on how to best derive a WE column. (The DT_DATE format is not susceptible to a /7, mod7 operation).
Thanks in advance,

Finding correlation using derived columns?

I want to use the aggregate CORR_S function which take two numerical columns and output the correlation between them. Assuming I have the table:
Employee(name, gender, salary) where I want to create two derived columns, how would I do it?
Like,
SELECT CORR_S(
SELECT salary
FROM employees
WHERE salary < 10000,
SELECT salary
FROM employees
WHERE salary > 10000
) as correlation
FROM employees
It will find the correlation between salary's less than $10,000 in one column and salary's more than $10,000 in another column. Of course, I get an error when running the query. It's no problem if I use CORR_S(salary, salary) but I want to use derived columns, is it possible? Or, will I need to create a new table view with two new columns CORR_S(lowSalary, highSalary)?
Thanks.

It may be correct sql query, but statistically ( i mean here the OP question, or at least how i interpret it) it is nonsense.
Clearly , correlation show how good distribution of one set of items corresponds to another set, so the order of item in the itemset does matter. Consider
SQL> WITH t AS (
2          SELECT 1 id1, 10 id2, 30 id3 FROM dual UNION ALL
3          SELECT 2 , 20 , 10 FROM dual UNION ALL
4          SELECT 3 , 30 , 20 FROM dual )
5 SELECT corr_s(id1,id2), corr_s(id1,id3)
6 FROM t
7 /
CORR_S(ID1,ID2) CORR_S(ID1,ID3)
              1             -.5So, it would make sense to calculate correlation between salary and hiredate, salary and department number, salary and employee name's length, whatever, but how can be correlated salary less 10k to salary more than 10k - i can't understand it. They are not in the same set, but in two different sets ( while one can have either more 10k or less 10k, but not both) and relation between these two sets is not given by OP.
Best regards

Derived Column: Assigning and and Using as a Condition

Hi,
I have 1 derived column component with 2 derived columns (see below).
1st derived col:
DerivedColName: col1
Derived Column: Replace 'col1'
Expression: REPLACENULL(col1, col1_DHH)
2nd derived col:
DerivedColName: col2
Derived Column: Replace 'col2'
Expression: ISNULL(col1) ? col2_DHH : col2
As you can see, col1 is being used as a condition to determine the value to assign to col2.
But at the same time, col1 is assigned with a value that depends on the result of REPLACENULL.
My question is, is col1's value in (ISNULL(col1) ? col2_DHH : col2) the original value i.e. before it evaluates the REPLACENULL expression?
I have tested this and it seems that col1 value is the original value (which is what i need). I just want to confirm from you guys that this is always the case i.e. it is deterministic.
Thanks!

If they're in same derived column then it takes original value ie prior to start of derived column
If you want evaluated value to be used for second expression then you need to use two derived tasks and join first to second with precedence constraint with option On Success

How to swap column values using variable in sql?

Hi,
I have a table and i want to swap two column values using variable
please help me

Hi,
Let us assume that the DeptNAME and DeptNo columns are of type VARCHAR2. However, DeptNO column is VARCHAR2(10) and DeptNAMe is VARCHAR2(100).
First of all DeptNo column needs to be modified to be 100.
i) ALTER TABLE DEPT MODIFY DEPTNO VARCHAR2(100);
Secondly, you will swap DEPTNAME and DEPTNO values using the SQL as follows:
ii) update dept t1
set deptname = (select deptno from dept2 t2 where t1.deptno = t2.deptno),
deptno = (select deptname from dept2 t2 where t1.deptno = t2.deptno);
Now, finally you want the deptname columns to be VARCHAR2(10)
iii) ALTER TABLE DEPT MODIFY DEPTNAME VARCHAR2(10).
If DEPTNO is a NUMBER column, you cannot alter the datatype unless the table is empty; in that case the whole swapping requirement would be moot.

How to access variable number of columns using ref cursor !

Hi,
I am trying to get variable number of columns using ref cursor.
Declare
mySzSql varchar2(2000);
Type dynSqlRC is Ref cursor;
current_cur dynSqlRC;
tbl_rec alt_42_consolidated%Rowtype;
Begin:
/* This works */
mySzSql := 'select *
from
Table1
Where
rowid = ''AAEWNEABXAAAAkxAAA''';
/* i want something like this to work, this is not working, giving missing variable name error */
mySzSql := 'select col1, col2, col3
from
Table1
Where
rowid = ''AAEWNEABXAAAAkxAAA''';
open current_cur for mySzSql;
fetch current_cur into tbl_rec;
close current_cur;
End;
I do have the list of desired columns which I am looking to fetch, so after taking that in the record type, how should i get their values. Is it possible to traverse tbl_rec declared above and if column name matches then I will store the value in the array and finally return this array.
Can somebody please tell me how to do this.
Thanks

It appears that this is a followup to How to loop through columns selected by select clause which is itself a followup to [url="

Assuming these are intended to be followup questions, can we please stick to a single thread? That makes it a lot easier to understand the situation and follow the conversation. Starting multiple threads makes it harder to follow the conversation.

Controlling table column alignment using variable

Hi I'm new to Javascript, having only used Applescript before.
I'm using Indesign 5.5 on Mac and I'm learning Javascript by adapting old Applescripts that I have been using for years.
So, with an existing table, one of the things I want to do is to set the alignments in the columns using a varible. Here's what I've tried so far:
function setColumnWidthsAndAlignments()
    var myWidths=[29, 23, 13, 13, 13, 13];
    var myAlignments=["leftAlign","leftAlign","centerAlign","centerAlign","rightAlign","rightAlign"];
    var numberOfColumns=myTable.columns.count();
    for (c=0;c<numberOfColumns;c++)
        myTable.columns[c].width=myWidths[c];
        myTable.columns[c].cells.everyItem().texts.everyItem().justification=Justification.myAlignments[c];
but I get an error
-- Object does not support the property or method 'myAlignments' --
If I discard the variable myAlignments and just put leftAlign for example, it works, so maybe I'm not declaring the variable properly?
I know I could add a few extra paragraph styles and cell styles and style the table that way, but I though this would be a good learning exercise (besides which I want to limit the number of paragraph styles in the document - there are enough already!)
If anybody is really interested, I'd like to place the whole script here and would really welcome any feedback on how the structure could be improved or optimised or just tell me if I'm heading in the right direction.
Thanks and regards,
Malcolm

    myInset=0.5;
    myTable.rows.everyItem().topInset=myInset;
    myTable.rows.everyItem().bottomInset=myInset;

You'd probably have more luck trying something like:
var myAlignments = [Justification.LEFT_ALIGN, Justification.LEFT_ALIGN,
Justification.CENTER_ALIGN etc.]
and then in the other line: ...texts.everyItem().justification =
myAlignments[c];
Alternatively, you could try keeping it as you have it, but perhaps
changing it to this:
texts.everyItem().justification = eval("Justification."+myAlignments[c]);...
which just creates a string and then runs it with eval.
At any rate, the problem as I see it with what you have is that you
myAlignments is an array of strings, and you cannot access a property of
an object (in this case Justification) with a dot+string. When you put
"Justification.leftAlign" and it works, I think that's because leftAlign
isn't acting as a string -- it's simply a property of the Justification
object.

SSIS: Using CASE Statement Within A Derived Column Transformation Expression

The following is my Data Flow:
Ole DB Source > Copy Column > Derived Column >Ole DB Command
My OLE DB Source has the following SQL command task:
SELECT *
FROM Repair R
LEFT OUTER JOIN Vehicle V
ON R.SN = V.SN
AND R.Reg = V.Reg
LEFT OUTER JOIN Product P
ON R.PID = P.PID
This yields a column of concern for me named PartNumber, which are represented by the following 2 formats:
The following are my Copied Columns:
Input Column = PartNumber
Output Alias = Copy of PartNumber
The following are my Derived Column expressions:
Derived Column Name Derived Column Expression
Name Replace 'PartNumber' LEFT(PartNumber,FINDSTRING(PartNumber,"-",1) - 1)
Copy of Name Replace 'Copy of PartNumber' RIGHT([Copy of PartNumber],LEN([Copy of PartNumber]) - FINDSTRING([Copy of PartNumber],"-",1))
So My PartNumber Column is Replaced with ######### of type
string and the Copy of PartNumber column is replaced with
#### of type int
As I stated earlier PartNumber also is in the format of %-%-% which raises the following question:
How can I replace PartNumber Column with NULL if in format of
%-%-% and take the PartNumber and put it in new column named
SubPart while keeping all the logic within SSIS objects?
So in essence I want to do something like the following:
PartNumber = CASE
WHEN 'PartNumber' LIKE '%-%-%'
THEN ABC = PartNumber AND PartNumber IS NULL
END
I have tried the case statement in a Derived Column expression and is not working. Would I add the
CASE statement to the SQL command task in my OLE DB Source?
I hope this question is concise for you.

If it must be in SSIS, I would put a derived column stage earlier in the process to do my check for me. Then in the second derived column stage do the check against each output column (part, subpart, copy of part) to decide which way it goes
PS Not sure if it's a 2012 function but SSIS has a function called TOKEN that will allow you to pull your subparts for you rather than the left/right you are doing

Create a derived column based on a value within the file name

I am importing a CSV file which is easy enough, but I have an issue where I need to manufacture a couple of column values based on the filename of the input. So this same process will import different types of records to the same table in sql server.
I need to pull out the record code from the file name.
For instance, say I can use the same package to input two different CSV files. One is named Input_M02_Data.csv and one named Input_B15_Data.csv. I need to create a derrived column and store the record code there (i.e.: M02 or B15) based
on which file it came out of.
fyi-
I also need to create a second column for Dept based off of the file name as well. M02 is dept 45 and B15 is dept 99 which I also need to insert into this table when I import the data from the .csv file.
Any help is greatly appreciated!

Hi Jason,
According to your description, you want to add two derived columns based on the file name to also insert into table. One stores the value between two “_” within file name, another stores the department based on that column.
If in this scenario, we can add a variable FileName that stores the filename, then add the two variables as derived columns like below in the Derived Column Transformation:
Name:
SUBSTRING(@[User::FileName],FINDSTRING(@[User::FileName],"_",1)+1,FINDSTRING(@[User::FileName],"_",2)-(FINDSTRING(@[User::FileName],"_",1)+1))
Dept:
@[User::Name] =="M02"?"dept 45":@[User::Name] =="B15"?"dept 99":"dept 00"

Truncation in derived column

Hi guys, I have got a table with a column (wrongfile nvarchar (300)) and a package with a Derived Column in this way:
I I had to ignore the truncation because it always retrieved "truncation occurred..." but now if I see the table the column wrongfile is empty and I am wondering why by the way that the column in the csv file it less than 100 characters..

Change your expression to cast the variable to Unicode:
(DT_WSTR, 300) @[User::NBFile]
It appears that if you create a column using derived column it gets the length from the variable. So if it is empty when you create the component, SQL Server will create a 0 length output.

Using variable with the same name as field name?

I have a complex proc where I have variables with the same name as field name used on a query. something like this:
SELECT a.id_table WHERE a.id_table = id_table
where the last id_table is a parameter sent to the proc:
declare procedure myproc(id_table int)
Is there any way or notation to declare the variable inside the query as a variable or I have to use a different name?

Well, variables are not the only thing you have to change if you want to switch to Oracle.
Although I don't think it is good practice (to use variable name same as column name), here is one example how you can achieve it using EXECUTE IMMEDIATE and bind variable
SQL> select deptno, count(1)
2 from scott.emp
3 group by deptno;
    DEPTNO   COUNT(1)
        30          6
        20          5
10 3
SQL> set serveroutput on
SQL> declare
2 deptno varchar2(10);
3 i number;
4 begin
5 deptno:=10;
6 execute immediate
7 'select count(1) from scott.emp where deptno=:deptno' into i using deptno;
8 dbms_output.put_line('OUT ---> '||i);
9 end;
