So, "selection criteria" is used as the WHERE clause in the generated query. For example, let's say you wanted to select only those records where a field named "ACTIVE" in your file is equal to 'Y'. You would put this into the "selection criteria" property:
On the other hand...

The "custom sql" property is used INSTEAD of all the other properties. Using this property, you specify the entire SQL query yourself. You might use this to get a more complex query, such as one that joins multiple files.
