Question : SSIS Update OLE DB Command Parameter Syntax Error

I have developed an SSIS package that performs an "UPSERT". There is a data source (Sharepoint List), a Lookup on a certain ID (which I've already got working, and then if the lookup match fails it inserts rows just fine; however, when the lookup finds a match it goes to an OLE DB Command object which I'm having trouble configuring.

The issue I have is I keep getting Syntax errors returned from the SQL server because I am using question marks as input parameters in my SQL statement:

UPDATE dbo.Deployments
SET
      Status = ?,
      FirstName = ?,
      LastName = ?,
      Email = ?,
      ExternalUserID = ?,
      DeploymentLocation = ?,
      DeploymentDate = ?,
      EndDate = ?,
      Hardware = ?,
      Accessories = ?,
      Monitors = ?,
      OS = ?,
      Software = ?,
      SpecialRequests = ?,
      PM = ?,
      AssignedTo = ?,
      Ticket = ?,
      SubmittedDate = ?,
      WHERE SharepointListID = ?

According to all the tutorials I have read, this is supposed to work. I have defined External Columns and have been able to successfully map all the columns properly; however, when it goes to execute it always bombs out with this error:

[UPDATE Deployments Table [593]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80004005 Description: "Syntax error, permission violation, or other nonspecific error".

It's definately not a permissions issue. I've already worked that out. What am I doing wrong?

Answer : SSIS Update OLE DB Command Parameter Syntax Error

I see that there is a comma " , " after the last column before WHERE .. remove it..Also, make sure that columns and parameters have same data types..of course should be mapped correctly

Try the code below
