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 ?
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?
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.

HI,
I had to change the key columns of a dimension attribute to fix an error. I did this in BIDS. The change was from a single key column to a composite key column. Now I am getting these error when I process the cube:
Measure group attribute key column x does not match source attribute ..
I looked at the cube XMLA definition under mesaure groups and it still shows a single key column with inherited binding. However, the BIDS does not give me an option correct this in any way. I have had to do this once before and the only option seems to be removing the dimension from the cube and add it back in. But that is very error prone since I lose any specific settings at the cube dimension level not to mention aggregations no longer include the dimension, etc.
Not seeing an alternative, I went through each measure group (I have 7) and changed the key columns manually in the XMLA and saved the cube. This worked, but I don't understand why BIDS automatically doesn't do it.
Is this a flaw in the BIDS or I should be missing something.
thanks

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".
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.
Any help in this will sincerely be appreciated.
Thanks

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:
'**********************************************************************
' Visual Basic Transformation Script
'************************************************************************
' 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.
thanks in advance!

Table structure as follows
Employee
Empno empname salary
commission
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.
something like
Select empno , empname , salary , commission,
(salary + commission) as derived_colum1 ,
(derived_colum1 + xxxxx) as derived_colum2 ,
(derived_colum2 + xxxxx) as derived_colum3
into employee_modified from employee
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.

Beli
Hi All,

I want to insert attibute att1 in field F1 . Value for this attribute is content of another field in this table (F2).
My query :
update MyTable
set F1.modify
('insert attribute att1 {sql:column("F2")} into (/ROOT/Node1)[1]')
Where F1 Is not null
But I get this error :
XML well-formedness check: Duplicate attribute 'att1'. Rewrite your XQuery so it returns well-formed XML.
How do I check the douplicate attribute ?
Hello Everyone,
I am creating a Metadata management application for a business intelligence platform on SQL Server 2005.
For this purpose, I've set out to consolidate all DB-object metadata (Databases, Tables, Columns, Views) into a single repository that business users can browse through. It has been fairly straightforward so far, but I've hit a wall in the views department.
In fairly simple terms, I want to know which physical columns are selected in a view, with the twist of also knowing the columns' alias. This seems to be impossible as far as I can tell, it is easy enough to get both of these independently, but I can't figure out how to connect an alias to an actual column.
(I prefer to use the metadata catalog views to the INFORMATION_SCHEMA as I need to know the object_id's)
Aliases are easy enough to obtain:
select object_id, column_id, name
from sys.columns
where object_id = object_id('SomeViewsName');
As are the 'physical' columns:
SELECT
t.object_id as TABLE_OID,
c.column_id as COLUMN_OID,
c.name
FROM
sys.views v
JOIN sys.sql_dependencies d
ON d.object_id = v.object_id
JOIN .sys.objects t
ON t.object_id = d.referenced_major_id
JOIN sys.columns c
ON c.object_id = d.referenced_major_id
AND c.column_id = d.referenced_minor_id
WHERE
d.class < 2 AND
v.name = 'SomeViewsName';
As I've said before, the problem is joining these two datasets. One of the problems associated with this is that the latter query also returns columns used in JOIN statements, even if they are not projected in the select part of the view definition.
Ultimately I'd like to get this result:
Alias used in View, physical table's object id, physical column's id
Am I missing something?
Thank you very much in advance for your help.
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?
Thanks
Hi,
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?
Thanks,
Megan
Hi Guys,
How can i put in a derived column the value of 3 columns? I've tried these:
[MyId]+[Paper1]
"[MyId]+[Paper1]"
but no luck. How can i put it right?
Thanks

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:
DTSDestination("TransactionDate") = cdate(DTSSource("DSRHDATI")) & " " & timevalue(DTSSource("DSRHTIME"))
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.

Can someone help me with the following query? I need to take the derived value from one column and calculate another column with it.
SELECT UserID,
((SELECT COUNT(*) FROM HPN_LeadMatches)+(SELECT COUNT(*) FROM HPN_Painters)) As Total,
(SELECT COUNT(*) FROM HPN_Leads) / Main.Total
FROM HPN_LeadMatches As Main
The error i'm getting says is unkown column 'total'. Is there another way to accomplish this?
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.
let a = x + y; a²
as the expression for new row b?
Hi everyone,
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 -
score = (correct Qs answered) * 150 / (total Qs answered) + (total Qs answered)
The SQL query that i use to get this info is -
Code:
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'.".
Surely there must be a simple way to do this?
Thanks.
Two questions regarding Derived Columns in SSIS
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.
Hi All
I m designing SSIS having Data Flow as
Flat File > Derived Column Transformation > Destination Table
but while transfering record from text file to table i need some logic here
my text file is
"ID"|"Name"
1012|"10AA"
1013|"10BB"
logic is 10 should be replace by variable VID = 98
I defined this veriable as int
My ID column in database is int and Name column is varchar(50)
I try here expression like
ID != 98 ? @[User::VID] : ID
it work fine
but for varchar column I am not able to do
I got error when i write expression
SUBSTRING(Name,1,2) != "98" ? [DT_STR, 50, 1252] "(@[User::VID])" + rest of value of column : [Name]
my final output in table should be like
ID..Name
98..98AA
98..98BB
Please help me out

I would like to validate datatype using Derived Column.My data type are such as numeric(X,X),datetime,int, and varchar.How do I do this using Derived Column.Example if row does not qualify as ISNUMERIC()...throw it in ERROR table else send it to SUCCESS table.Any Idea ?
View 4 Replies View RelatedHi,I have a view that looks something like this -CREATE VIEW myview AS SELECTmyudf(col1) as col1, col2, col3FROM mytableThe view has an 'INSTEAD OF' trigger on it to do the correct thing oninsert. When I run the bcp, it runs successfully, but the valueinserted into col1 is always NULL. I modified my trigger to get abetter idea of what was happening, and when I look at the values ofINSERTED.col1, they are all null. It appears that bcp is setting thecolumn value to null, presumable because the view definintion for thiscolumn is a derived column.Does any one know a way around this?Thanks!

Hi there,
is there a way that I can set the value of a column to the currrent user in a derived shape?
For instance if I want to set the value of a column to the current data I can merely use GETDATE().
What is the current user equivilent?
Thanks
Hi,
I have just started learning SSIS. I have created a new package which is as follows :
SOURCE QUERY ----> Derived Column ------> Destination Customer Info
Source Fields are
FirstName
LastName
OrgCode
Phone
Ref1
The Derived column is adding a new Column name FullName and the friendly expression for it is FirstName + "Null" + LastName
Destination has all the columns are same as source columns with similar datatypes.
When i start the debugging process i get the following error:
[Destination - CustomerInfo [29]] Error: Column "FullName" cannot be found at the datasource.
[Destination - CustomerInfo [29]] Error: Cannot create an OLE DB accessor. Verify that the column metadata is valid.
[DTS.Pipeline] Error: component "Destination - CustomerInfo" (29) failed the pre-execute phase and returned error code 0xC0202025.
Please let me know where i am going wrong.
Thanks
Hi,
I apologize if this question has already asked (I already looked in this forum but do not find the answer), I need to have this done as soon as possible. I've following data:
column1 column2 begin_date active
------------- ------------ ---------------- -----------
1253 1057 1/1/2006 0
1253 1057 1/1/2007 0
1253 1057 4/1/2007 0
1253 1057 7/1/2007 1
I need to have the final result as following: (the new end_date column is the value of the begin_date in the next row -1)
column1 column2 begin_date active end_date
------------- ------------ ---------------- -------- ------------------
1253 1057 1/1/2006 0 12/31/2006
1253 1057 1/1/2007 0 3/31/2007
1253 1057 4/1/2007 0 6/30/2007
1253 1057 7/1/2007 1 null
Any ideas?
Thank you!
I want to implement all this four condition in one derived column expression.
if (Column1== 1)
{
OutputColumn = ColumnA- Column1RATE
}
if (Column2 == 1)
{
OUtputColumn = ColumnA- Column2RATE
}
if (Column3 == 1)
{
OUtputColumn = ColumnA- Column3RATE
}
if (Column4 == 1)
{
OUtputColumn = ColumnA- Column4RATE
}
please suggest
Example: (47 / 204709) * 12000 = 2.754
Both values (47 & 204709) are of data type Int.
SQL Sever - Derived Column Calculation returns 2.74
The destination data type is Float
I have converted the data types to Float, Decimal & Numeric and still got the same answer.
Any suggestions
I am importing States into a table and need to change all NULL fields before I perform a lookup. I'm using a derived column to replace the state value. I'd like to find all States that are blank and set it to "--".
Ironically, this works:
State != "" ? State : "--"
but
State == "" ? State : "--"
Does not work
Can someone tell me why?
I have this expression
(Registered_Units == Limited_Units) ? 0 : (Painted_Units / (Registered_Units - Limited_Units)) * 100)
It gives me 0.00, although those 3 columns have values.
if I cast it like this
(Registered_Units == Limited_Units) ? 0 : ((((DT_DECIMAL,2)Painted_Units) / ((DT_DECIMAL,2) (Registered_Units - Limited_Units))) * 100)
It gives me correct answer in whole number but .00 after decimal.
Any clue how to fix it ?
