Dynamic SQL In SSIS With Oracle

Hi ,

1.Dynamic Sql

----------------

My source table is Oracle .we want to have dynamic query the following steps we have done.

a.Created a new variable called StrSQL & ProductID variable contains values for where clause.
b.Set EvaluateAsExpression=TRUE
c.Set Expression=""select * from prod where product_id = " + @[ProductID] 
d.OLE DB Source component, opening up the editor
e.Set Data Access Mode="SQL Command from variable"
f.Set VariableName = "StrSQL"

But i am getting the following error

Error at DataFlow Task[OLEDB Source[1]]:An OLEDB error has occured, Error code: 0x80040e14.
AN OLE DB records is available . Source "Microsoft OLEDB Provider for Oracle" Hresult: 0x80040e14
Description : "ORA-00936:missing expression

What could be the problme.how about the support of dynamic query (Oracle) in ssis?
