Need to convert all the fields from the Oracle ADO source in data flow.

Hi All,

I am eager to take advice on the situation I am in.

I have one table in oracle database in which the datatype of the fields are declare like Varchar2(40 BYTE), VARCHAR2(80 BYTE) etc. There are 30 such fields which are having string data fields and this is my Ado.net source for oracle.

So, when i check all these 30 fields have DT_WSTR in output columns in advanced editor of source.

Now, my destination is SQL Server and I have these 30 fields as Varchar datatypes.

There are two situations 

1] Whether i can put data conversion in the data flow for 30 fields.

2] Or Double the size of the SQL table columns with Nvarchar; (Not sure if this will remove the conversion error I am getting right now).

I know the overhead of converting 30 fields in data conversion task in ssis for order table of 1 month period daily.

Please advice.

Thank you
