Custom Transform Component, Change Type Or Add Output Column

Jun 26, 2006

Would anyone happen to have any pointers or know of any good code examples to either programmatically change the type of an input column when it is passed through the component, or add a new column to the output? I am extracting data from an Oracle database which is in Julian date format (represented within SSIS as a DT_NUMERIC column) and I need to to either transform the input column holding it into a date column, or to dynamically add a new output column holding the transformed data.

Many thanks

Use Of A SSIS Variable Of Type “Object� Inside Script Component And Task Component

Mar 16, 2007

In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type.
On exiting from the script the variable of type object should contain something like in the following lines:
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDDDDDDDD
€¦€¦€¦€¦€¦€¦€¦.
€¦€¦€¦€¦€¦€¦€¦.
On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion.
Is there anyone who have experienced something like this? Could anyone provide any example of that?
Thanks in advance!

Pass NVARCHAR (or Other String-type) Var As A Column Or Table Name In SQL

Jun 21, 2004

Hey folks, the question is fairly simple, unfortunately the answer has proven rather elusive.

Is it possible to declare a variable which would then be used to identify either a column or table in an SQL statement?

Here's a basic idea of what I'd like to do:

DECLARE @myVar AS NVARCHAR(50)

SELECT *
FROM @myVar

or

DECLARE @myVar AS NVARCHAR(50)

SELECT @myVar
FROM MyTable



I'm probably looking for some sort of built in function that will accept an argument here... like COLUMN(@myVar) or something of the like. I just don't know where to look...

Dynamically Assign Connection String

Feb 28, 2008

I have 3 web identical web apps whose only diff is that they access different SQl Server DB's. I use the SQLDataSource in a number of pages to retrieve data from the db. The apps all use Forms Auth. I would like to be able to see who is the logged on user user and assign the approp connection string to all the SQLDataSources in the app. For example when user UserA logs in they are retrieving data from on db but when UserB logs in they are retrieving data from another db.
I am sure this can be done but could use a little guidance. Thanks in advance.

How Do I Assign A String To A Parameter I'm Passing To A Select Statement?

Oct 30, 2006

Hello, I'm needing to pass a variable length number of values to a select statement so I can populate a result list with items related to all the checkboxlist items that were selected by the user.  for example, the user checks products x, y and z, then hits submit, and then they see a list of all the tests they need to run for each product. I found a UDF that parses a comma delimited string and puts the values into a table.  I learned how to do this here: http://codebetter.com/blogs/darrell.norton/archive/2003/07/01/361.aspx I have a checkboxlist that I'm generating the string from, so the string could look like this: "1,3,4,5,7" etc.I added the function mentioned in the URL above to my database, and if I understand right, I should be able to pass the table it creates into the select statement like so:
WHERE (OrderStatus IN ((select value from dbo.fn_Split(@StatusList,','))) OR @StatusList IS NULL) but now I don't know how to assign the string value to the parameter, say to '@solution_id'.my current select statement which was generated by Visual Studio 2005 looks like this: SELECT [test], [owner], [date] FROM [test_table] WHERE ([solution_ID] = @solution_ID) ...but this only pulls results for the first item checked in the checkboxlist.Does anyone know how this is done?  I'm sure it's simple, but I'm new to ASP .NET so any help would be greatly appreciated.

T-SQL (SS2K8) :: Assign Next Available Column Values?

Sep 29, 2014

find below object and data:

create table #StuDetails(City varchar(25),StuStatus varchar(25), currentValue int,Week1 int,week2 int,week3 int,week4 int)
insert into #StuDetails values('A','new',13,10,0,0,12)
insert into #StuDetails values('B','Old',10,10,41,0,12)
insert into #StuDetails values('C','Fail',10,9,0,0,5)
select * from #StuDetails

Output of above is display as:

CityStuStatuscurrentValueWeek1week2week3week4
Anew 13 10 0 0 12
BOld 10 10 41 0 12
CFail 10 9 0 0 5

Now for columns Week1 to week3 if value is 0 then i want to display by searching next week value, if it is also 0 then go for next week and if value found there then display instead of zero. so my output would be as below instead of above.

CityStuStatuscurrentValueWeek1week2week3week4

How To Assign Previos Column Value To A Variable

Greeting.
I have a dataset (ORDER BY Column1) like the following in the data flow task pipeline




Column1 Column2

1 A
1 B
2 C
2 F
3 T
3 R
3 X
4 M



I only need data of 1, A;


2, C;

3, T
4, M
That is when Column1 value changes. I think we can store the column1 value in a variable as a previous row value. Then I can compare the variable value with the current row value and see if the column1 value changes. Can anyone please help me how to implement this? Or if there is other way to implement it

.
Thanks.

Values For Field Missing When Attempting To Modify Filegroup To Readwrite

Jun 2, 2015

I'm trying to swap out old partitions and getting "An error occurred while processing 'AltFile' metadata for database id 12 file id 605" 605 is missing from sys.sysfiles. I've tried adding new file groups since it seemed to be assigning them in that range to allow the command to find a match. Once created and I issue the alter command the file id of the target file changes to something else in the missing range.

The file id values seem to be managed solely by sqlserver so I'm not sure what to try. There are hundreds of files with millions of rows and the method has been used problem free for years. I do occasionally get "unable to remove file because it's not empty" once in a while which may be related. I wind up having to shrink those and leave them in existence.

The target file group has an existing file id value when you join sys.sysfiles using the filegroup name.

I partition data in 2 tables on one filegroup per day. I swap out parition 1 each day which makes the new earliest day's partition the new partition 1. Different databases have different day ranges depending on requirements.

Bulk Insert Task Failing On Data Type Conversion For A Destination Column Of Type Bit

Jul 6, 2006

I am trying to use the Bulk Insert Task to load from a csv file. My final column is a bit that is nullable. My file is an ID column that is int, a date column that is mm/dd/yyy, then 20 columns that are real, and a final column that is bit. I've tried various combinations of codepage and datafiletype on my task component. When I have RAW with Char, I get the error included below. If I change to RAW/Native or codepage 1252, I don't have an issue with the bit; however, errors start generating on the ID and date columns.

I have tried various data type settings on my flat file connection, too. I have tried DT_BOOL and the integer datatypes. Nothing seems to work.

I hope someone can help me work through this.

Thanks in advance,

SSIS Custom Data Flow Component - Variable Type Converter

Jun 27, 2007

Hi all,



I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).



Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)



I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.



Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?



To create a dropdown list of values for a custom property that represents an enum, do the following:

1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"

2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"

3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"

4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"

5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"

6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"

7. Override "GetStandardValuesSupported" and return true

8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted

9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"

10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"

11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"

The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.  

I copied the mdb file to a folder on the server which my packages have no problem reading data from.

My packages run under the same domain account as defined in proxies.

Appreciate a help.

Frror: 4000 Max String Literal In Expression For Datareader Component

Apr 15, 2006

Hi, I have a datareader component of which i am dynamically setting its sqlcommand statement with expression (click the background of dataflow > properties > expressions). Now my sql select statement has about 600 fields so that makes my expression statment "select field1, field2, .....from table1 where field2 >=" + @[User::dateforfield2] but when i evalute the expresssion (which is right), i get the error: A string literal in the expression exceeds the maximum allowed length of 4000 character and i think its because of the fields in my select statment causing my string literal to grow more than 4000 characters. Is there any way to increase the max string literal for expressions. Please help.
