i am importing data from database SQL server 2008 to csv files .The source data has unicode format and the destination is non Unicode.
As the source string can be very large i chose the the data type unicode text stream of the source column in stead WSTR in SSIS OLE DB source but due to this keeps on waiting on pre execute stage of Data flow task indefinitely
if i change the source column from Unicode text stream to WSTR it works fine
Please help if any one has any idea of this weird behavior
