I'm reading a .csv file that has a column such as 17June2007:00:00:00, how can I convert this column in my Derived Column routine so its inserted into my DateTime column in my database?
so far I've tried
DT_DateTimeStamp
DT_Date
DT_DBDate
DT_DbTime
and its kicking back errors on this column. What do I have to do to convert 17June2007:00:00:00 into a readable datetime for the database column?
I think that I've done a big mess on my work... I've got plain file which must be loaded into a sql table. Up to there no problem, I use Derived Column due to columns needed be transformed with NULL, RIGHT, LEN, and so on...
But in this last package I've done half of work using Data Conversion but I've got five columns which would need be transformed but I don't know how can I do such thing. I can't connect a Derived Column from Flat File Source task, of course, it's already data conversion...
Let me know if you need further details.
Previously I think, silly idea, that it could be unified or better, that Data Conversion task allows me make transformations...
It was my understanding earlier that -- it is mandatory to have a Derived Column for a DATE String in a Flat File to be loaded properly into a table with "datetime" column type
However, i tried running my package with the Input Column as "DT_STR" and the Destination on the table is DATETIME.
Looks like the process went on fine.. Am i missing something here?
My Date Format from the source looks like -- "DD-MON-YY"
I'm having trouble converting a date in the format of:
Jan 11 2006 12:00:00:000AM
to a smalldatetime in my new SSIS package. I'm trying the derived column transformation, but I'm at a wall now, especially with the conversion of 'Jan' string to integer/month/value of 1. Anyone have experience/advice on this transformation?
What happened to the DateTime String transformation in SQL 2000? Was that too unpopular to move to integration services? That transformation saved my butt many times - every banks' data feed we import uses a different date format.
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.
one of my SSIS packages use this expression to put todays date in if it is NULL:
(ISNULL(datejs)) ? GETDATE() : datejs
however, what I really want to do though is put a default date in like '2007-01-01' but I get syntax error because SSIS thinks it's a string, which it is I suppose.
Can someone confirm this for me? The expression language in SSIS has the same limitations on date ranges as Sql Server? That limitation is that valid date ranges are from Jan 1, 1753 to Dec 31, 9999.
When ever I try to do a date function (DATEPART, for example) in a Derived Column Transformation on a date less than 1/1/1753, I get an error. I initially discovered this when bringing data over from Oracle to Sql Server. Just as a test, I created a text file filled with various dates and tried to import it. Whenever a date is less than 1/1/1753, it blows up.
For example, this expression code - DATEPART("YEAR",Date) will yield this error - [Derived Column [24]] Error: The "component "Derived Column" (24)" failed because error code 0xC0049067 occurred, and the error row disposition on "output column "YEAR" (80)" specifies failure on error. An error occurred on the specified object of the specified component.
As a workaround, I've been using a Script Component to do date checking, but this is obviously not ideal.
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.
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.
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,
Hi, Basically the above is a very common requirement, please comment on my solution which I've arrived at by searching through the web; -
In summary I have used 3 SSIS components these are "Flat File Source", "Derived Column" and "SQL Server Destination".
1) File Connections Manager Editor 1.1) Within File Connections Manager Editor; - Name the data type e.g. "INTERCHANGE_NET_APP_DATE_SRC" and assign a type to the data type e.g. string[DT_STR]
1.2) Click on the Preview button to ensure the expected text is assigned to the expected data type.
2.4) Select "database timestamp [DT_DBTIMESTAMP] " as Data Type.
2.5) Within the Mappings tab of the SQL Destination Editor have; - Input Column as INTERCHANGE_NET_APP_DATE and Destination Column as INTERCHANGE_NET_APP_DATE.
Please comment on the above, I will then pass on my suggestion to Microsoft.
How can I validate the date that is coming across in a 8 byte character field via an expression? It will either be a valid date or 0. If it is zero I want to make it a null.
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 = a
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.
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 ?
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
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 ?
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!
