问题 I have been trying for the last 10 hours to solve the following problem: I have a ForEach Loop container that is enumerating Excel file names in my Control Flow. Within the ForEach Loop container I have an Excel Source that imports data into Sql-Server. This connects to a Derived Column transformation using User::FileName as the expression that connects to a OLE DB Command that that maps to the User::FileName to a Report_Date (the Excel file names contain the report date) column in Sql-Server

问题 We have a test package that was designed using VS2017 that has one "Data Flow Task" object with "ODBC Source" and "ODBC Destination" objects within it. The package is simply trying to move records from table 'Table_1' to table 'Table_2' in the same SQL Server 2014 database named 'Test'. When we execute the package from VS2017, it runs successfully. However, when we import that package into SSIS, and then run the package directly from there, we get the following error messages (see screen

问题 I am trying to programmatically create an SSIS package containing a simple data flow from table A to table B in the same database. I am using the example given here. The package gets created and saved to a dtsx file, but when I open it in visual studio I see that the source and destination tables have not been selected. I also want to insert a transformation task in between before it reaches the destination. EDIT Well I have managed to get the source and destination tables selected and the

问题 I'm using a Derived Column Task to change column data using a CASE WHEN statement. However, I need to be able to say.. SQL CODE WOULD BE: CASE WHEN Column01 LIKE '%i%' THEN '0' ELSE '1' END In SSIS Expression Language that would be: [Column01] == "i" ? "0" : "1" (that's for equals i, not, LIKE %i%. Is it possible to use a LIKE operator? 回答1: I believe you'll want to use the FINDSTRING function. FINDSTRING(character_expression, searchstring, occurrence) ... FINDSTRING returns null if either

Recording error descriptions in an SSIS Data Flow (VS2008 BIDS)

阅读更多关于 Recording error descriptions in an SSIS Data Flow (VS2008 BIDS)

问题 I'm trying to use event handlers to log errors in my SSIS packages. Unfortunately there is no option to add event handlers to individual tasks within a data flow task; I have consequently added an event handler to the overall data flow task at the control flow level. When an error occurs within the data flow task I would like this event handler to trigger once , recording the error and any kind of error description possible. I initially set the error handler trigger to OnError , however this

How do I get SSIS Data Flow to put '0.00' in a flat file?

阅读更多关于 How do I get SSIS Data Flow to put '0.00' in a flat file?

I have an SSIS package with a Data Flow that takes an ADO.NET data source (just a small table), executes a select * query, and outputs the query results to a flat file (I've also tried just pulling the whole table and not using a SQL select). The problem is that the data source pulls a column that is a Money datatype, and if the value is not zero, it comes into the text flat file just fine (like '123.45'), but when the value is zero, it shows up in the destination flat file as '.00'. I need to know how to get the leading zero back into the flat file. I've tried various datatypes for the output
