1.i want to use simple quey "select * from....) in ole db source 2.which component can i use the function (udf) on the some column, (after the ole db source)?
inbs .. As per James K, all you need to do is modify your query in your ole db source. It is assumed you are using SQL Command as data access mode in the ole db source task.
Based on James K ..
select *, dbo.f_trn(cust) as newColumnName from customers
The query will give you all columns from the customer table and newColumnName column
