Error At Data Flow Task Ssis.pipeline One Or More Component Failed Validation
because the data types of the columns you are attempting to associate with each other are different. One source may be a DT_WSTR (unicode string) and the other may be a DT_STR (localized string) - or one may be a DT_I4 (signed int) and the other may be a DT_UI4 (unsigned int). The Union All component can only merge data from sources that have the same data types.You need to use the Data Conversion component or the Derived Column component to alter the types of one of the flows to match the other before you attempt to Union them.

I received a comment in the blog post, asking for the functionality http://beyondrelational.com/modules/2/blogs/51/Posts/19051/ssis-union-all-data-flow-transformation.aspx of Union All task and why and how it is used. This blog post is for the same. SSIS consists of various Data Flow Transformations, and Union All is amongst one of them. The Union All transformation combines multiple inputs into one output. For example, the outputs from five different Flat File sources can be inputs to the Union All transformation and combined into one output (MSDN definition) The functionality is pretty simple, as the name suggests, multiple inputs and one output, similar to the T-SQL Union All command. Let us create a sample package using Union All. First of all, Drag a Data Flow Task in the Control Flow. In the Data Flow task, drag two OLEDB source, or any different type of source you need. Select the Connection and Set the Data access mode as SQL command, and write the SQL Command text as OLEDBS Source ----SELECT Data = 'Table1' OLEDB Source 1 ---SELECT Data = 'Table2' Add the output of both these OLE DB Sources to Union All transformation. Union All will automatically define its own Output Column Name, derived from the input column names. It will even automatically merge two matching input column names. If your input column names are different,
: Union All Transformation Error —Metadata for input columns does not match the metadata for output Our Client has an SSIS package. I’ve been working on that one for monthly https://victoriaxuan.wordpress.com/2013/12/06/ssis-union-all-transformation-error-metadata-for-input-columns-does-not-match-the-metadata-for-output/ data migration twice. It has been working well until today. This morning I got the new requirement- to load the Oct. datasets from delimited and fixed width Flat File, CSV, EXCEL, DIF. After http://blog.hoegaerden.be/2009/05/28/tip-changing-data-type-in-ssis-merge-component/ reset all the connection manager, I opened each source file to update the dataset. For Oct. we have 46 source File so they are 46 inputs to Merge by using Union all. There error at is a column is called “ExtCost” I got the following error: Error at Import mat [Union All [330]]: The metadata for "input column "ExtCost" (8979)" does not match the metadata for the associated output column. Error at Import Mat [Union All [330]]: Failed to set property "OutputColumnLineageID" on "input column "ExtCost" (8979)". Well, we are not able to change the metadata, so to solve this kind error at data of issue, If you would like to dynamically create SSIS packages, then leave the input columns in the source component as they are, and insert a Derived Column transformation (right after the source) with a SUBSTRING function to limit the length of the new column. But If your situation is that--you have already have the derived column transformation and data conversion transformation, the union all is after them. You can check all the path by right click it, see “metadata” , check those metadata which are before the union all and after the resource files. Copy them on the clipboard , compare the metadata in the data flow path. Because we are not able to change the metadata data, we can only change our input and output. As we have the derived and conversion transformation, we edit the data conversion transformation for those has input and output metadata unmatch. (From what you paste on your clipboard, you can find them). Then edit union all transformation, to remapping again. Then the Union All should be no errors any more. You can continue to do the later transformation for the merged dataset. Share this:TwitterFacebookLike this:Like Loading... Related Posted in Uncategoriz
component May 28, 2009 in Integration Services | 2 comments Here's a quick tip on the usage of the Merge, one of the Data Flow Transformation components in Integration Services. When merging data from two different sources one of the issues that you'll need to cope with are the data types. The Merge component may start complaining about certain columns when the metadata has been changed higher in the flow. The error would look like this: Validation error. Data Flow Task: Data Flow Task: The metadata for "input column "YourColumn" (590)" does not match the metadata for the associated output column. A common issue is the length of a string field. My favorite way to solve these types of issue is by opening up the Advanced Editor, locating the particular field in the Output Columns and increasing its Length property to match the length of the longer field. But unfortunately the Merge component does not have an Advanced Editor option. The easiest way to solve it in this case is by first deleting the column in the Merge Transformation Editor and then adding it again. Luckily the dropdown only shows the input fields that haven't been matched yet.

Thank you, thank you, thank you. Reply Ian Henderson on February 19, 2015 at 11:56 AM I had a very similar problem. Unfortunately though I couldn't delete the individual columns. Or at least I could but it moaned at me when I tried to add them again. It's a bit of a sledgehammer-to-crack-a-nut solution, but you can just delete the Merge component altogether and add it back in. It'll obviously moan until you've specified the data sources but once you've got those in you should be good to go. Reply Reply Click here to can
