Union All Component Silently Changes Output Field Length
Jul 25, 2007
To simulate problem do follows:
1. Add Script source component.
2. Add 2 string output collumns: F1 length 50, F2 length 110
3. Add Union All component connected to Script source component
4. Add Script transformation component connected to Union All component
5. Mark F1 and F2 as input collumns
6. In the Input and Output section of the script transformation component check that length of the fields is 50 and 110 correspondingly
7. Edit Union All component: change Union All Input 1 to <ignore> for Output collumns F1, and F2; change Union All Input 1 to F2 for F1 and F1 for F2; change back <ignore> for F1, <ignore> for F2; set back F1 for F1, F2 for F2; Click OK to save
8. In the Input and Output section of the script transformation component check that length of the both fields is 110 now.
So, be careful to select output columns values in Union All component. If you choose wrong field by accident, and replaced it with correct one straight away, the length of output column could be stored not as you expect an need.

I have found not very good behavior of Union All Data Flow Component.
I have Script component and about 30 Union All Data Flow Components. I have string field named 'MyField'. Legth of the field is 15 characters. The field appears first in Script component (defined as 'MyField' Output collumn) and present in all Union All Data Flow Components. I need to change field length from 15 to 10. In Script Transformator Editor of Script component I changed 'MyField' Output collumn Length property value set it to 10. But length of the field remains 20 in all Union All Data Flow Component downstream and no errors no warnings appears. To fix this i recreated (deleted and added again) 'MyField' in all Union All 30 Data Flow Components.
If extend length from, say, 15 to 20 in the first of Union All Data Flow Components error sign appears
"Error 1 Validation error. Data Flow Task: Union All [22]: The metadata for "input column "MyField" (144)" does not match the metadata for the associated output column."
and only recreation of the field in all Union All Data Flow Components can help to fix it.
May be someone knows other solution to fix such behavior?

My script component defines a (DT_WSTR, 450) output column named keyword. How can I access its length within the script, instead of hard-coding 450 as a constant?
My feeble attempts to tease this out through Visual Studio got me this far:
Output0Buffer.keyword.GetType.GetProperty("Length").GetValue(
but now I'm stuck. Also, if it matters, this is an asynchronous transformation component.
Thanks!

Hello,
I am running a stored procedure thru' isql.
This returns only one field.
The sp is executed fine but if the data has length greater than 255 the data is truncated.
How do u capture the full output ?
Thanks In Advance

I am using a Union All component in a Data Flow Task. I have 3 Input OLE DB Sources connecting to the 1 Union All component. And then the Union All component connects to OLE DB Destination component. Everything looks good, but for some reason, for every time the Data Flow Task runs, 3 rows are inserted into my table. Why is that? Isnt Union All joining all fields, and then just inserting 1 final row to my table. What am I doing wrong or what should i do to just insert 1 row in my table. Thanks and I am really anxious to see responses on this post. Thanks again.

I have a very strange situation. I've increased the size of an NVARCHAR field from 8 to 9 in a database table. The format of the data that I enter will either be an 8 character field (123456-8) or a 9 character field (1234567-9). The '-' is critical.
It used to only accept the 8 character version, but after increasing the field size, if I try to insert the 9 character field version, it gets truncated after the '-', as though it's still only allowing 8 characters. But that only occurs when I include the '-' or other such characters like '#'. If I try to insert 1234567a9, it works. The following explains the outcomes:
Inserted Value -> Result in table
123456-8 -> 123456-8 *Correct
1234567-9 -> 1234567- *Wrong
123456789 -> 123456789 *Correct
1234567#9 -> 1234567# *Wrong
1234567a9 -> 1234567a9 *Correct
Why is it that characters such as '-' and '#' are truncating the value, but only if the string is 9 chars long?
I'm currently using a direct t-sql insert statement in SQLExpress. The field is a simple NVARCHAR(9) field.

Hi,
I am sending the output of a query to a file and unfortunately every row is containing only a certain number of characters. My query has rows having length of 1500 characters for each row. When I get the query and send it to a file I am seeing only the first 250 characters for each row instead of 1500 characters.
I will be grateful if anyone can help me suggesting a solution for this problem.
I appreciate your help in advance.
thanks,
Sravan.

On my busy sql server my network output queue length is a very large number 4343559902. My research shows it should be a < 2, but have also seen some bugs related to this perfmon counter. Anyone dealt with this issue before?

I need to write data into a fixed column length file and was wondering the best (most efficient) way to tackle this. For example, the first few pieces of the report I'm working on now would be:
PacketID - Starting position 1, Field length 9
TransactionID - Starting position 10, Field length 9
Group number - Starting position 19, field length 10
PID/SSN - Starting position 29, field length 10
For the PID/SSN, if I have a PID it'll be 10 digits and fill the field length, if I don't I use SSN which is only 9 digits and enter a space as the 10th digit. Obviously if I don't have certain pieces of information I'll just need spaces of the specified length to satisfy the file format. I'm using SQL 2005. Thanks in advance for any help provided.

Hello,
I have an ODBC connection manager to a Progress database. In that database there is a column declared as a string of 10 characters long.
However, some data in this column is actually up to 15 characters long.
This makes my DataReader Source fail everytime I try to run my package because it sets the output column like this :
Datatype : Unicode string [DT_WSTR]
Length : 10
Is there any way to solve this without changing the datatype in the Progress database (that is beyond my control) ?
tanks in advance ...

I am having a bit of trouble writing a query that dynamically outputs what I need.
I have a table that looks like this:
COL1 AAA BBB CCC
CAT 1 3 3
CAT 1 2 2
CAT 1 4 4
DOG 2 3 3
DOG 5 5 5
MICE 1 1 1
I need it to dynamically output based off COL1, the output should look like this. When there are more rows for CAT, it should output more columns. Kind of like merging the columns
COL1 AAA BBB CCC AAA BBB CCC AAA BBB CCC
CAT 1 3 3 1 2 2 1 4 4
DOG 2 3 3 5 5 5 NULL NULL NULL
MICE 1 1 1 NULL NULL NULL NULL NULL NULL

I have a database on sql2000. I want to change the length of a field in Table A, but it is related to another field in Table B. When I tried to change the length of the field in Table A via
ALTER TABLE table ALTER COLUMN field varchar(5).The query analyzer generates the following error.
Server: Msg 5074, Level 16, State 8, Line 1
The object 'UQ__table__77BFCB91' is dependent on column 'field'.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE ALTER COLUMN field failed because one or more objects access this column.While when I tried the same query on the field in TABLE B, the query completed without any errors.

I'm sure it is possible to select all records where the length of a given field equals a certain value, but I don't know how to do it?

Hi Guys,
I have a Data Flow which consist in a Flat File Source connected to a Derived Column that is connected to an Ole DB Destination
In the same Data Flow i have an script source task which i want to connect to the same Ole DB Destination mentioned before.
I cannot do that because it says that the destination component does not have any available imputs for use in creating a path.
I know the Script Source Task has an Output Column because i verified it.
Is it possible to connect a flat file source AND a script source to the same Ole DB Destination?

There are two fieldsA1 nvarchar(30)A2 nvarchar(800)I know nvarchar field is alterable length, if I store a string mystring='abc' to A1 field or to A2 field, I think they use the same disk space, so I think it's always a good way to define a big length nvarchar field such as A3 nvarchar(4000) for any length string, becuase they always use the same disk space, is it right?

I have to modify field length in the table, which is part of publication. I tried to use an Enterprise Mgr and received an error message because that table is scheduled for replication.
Is any way around this beside temporary stopping and restarting replication? And actually how to do this to be sure that after restart the data will be again in sync.
We have SQL Server 2000 Enterprise Edition and Windows 2000 Advanced Server.

I am working with the Data Flow Task Script Component for the first time. I have created a second Output. In my script I add rows to this output.
I have found that Ssis does not release those rows to the second Output until it has processed all of the incomine pipeline records. This will not work for me as there are going to be a few million records coming down the pipe, so I need the Script Component to as soon as possible release these records downstream for insert into the destination component Ole Db component.
Any help would be greatly appreciated?

For the Custome source Component ErrorOutput, should I go for asynchronous / synchronous Output.
If i go for synchronous output
// Create the error output.
IDTSOutput90 errorOutput = ComponentMetaData.OutputCollection.New();
errorOutput.IsErrorOut = true;
errorOutput.Name = "ErrorOutput";
errorOutput.SynchronousInputID = What Id is required here;
errorOutput.ExclusionGroup = 1;
Is it the IDTSOutput90 InPut.ID / OutPut.ID which should be assigned.
Thanks Regards

HI,
I have a script component in my SSIS solution that transforms a URL that points to a picture to an URL that points to a thumbnail of that picture.
I've added an output called Picture to the component, and an outputcolumn called ThumbnailUrl, the code in the component is as follows:
PictureBuffer.AddRow()
PictureBuffer.ItemID = Row.ItemID
PictureBuffer.Url = Row.CopyoffotText
PictureBuffer.ThumbnailUrl = Row.CopyoffotText.Replace("-220.jpg", "-68.jpg")
VS then gives the following error: "Name 'PictureBuffer' is not declared"
What did I miss?
