Hi All,
I want to extract a numeric value from a string. Example, in a string like - Mgmt Pack: Processor Exception Threshold >80% Every 10 Minutes. - I want to extract that number 80. Since, later I'll want this number to plot a graph.
Since this is going to be an alert pulled from OnePoint (MOM Operational Database), the number will vary, and so I cannot look for the same number. So, can anyone help me how to get this working?
Thanks a lot in advance and let me know if the question is not clear.
Manoj Deshpande.

Is it possible to write a sql statement to skip aplpha numeric values? I got a field containing these values; 20, 70, 150, 140, 100, KORT, 90, 180, 160. And I'm trying to check if any value is bigger than 175 (@Limit), but I want to skip the value 'KORT'. So is it possible to check if a value is numeric or not? ISNULL( CONVERT(int, ProductVariant.Size), 0) > @Limit Regards, Sigurd

Dear All,
the situation is that i have a column data comes from flat file and all i want to do is to check that the incoming column is numeric(12,3) and if the incoming data exceed that size "12,3" exception or redirect the row is happened.
the problem that i try to apply that with the data conversion or Derived column component but it in case of the scale of the incoming data exceed 3 the component trim until 3 scale.
i also try to perform it with the flat file data source component but i face a problem that if the data in the column is empty then flat file data source component read the numeric column as Zero
i hope someone help me coz i need to handle it soon.

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!

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,
Beli

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

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.

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.

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 ?

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

Hi,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,
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

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:

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

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.
