deltaImportQuery
SQL query used if the operation is delta-import.
SQL query used if the operation is delta-import. If this is not present, DIH tries to construct
the import query by(after identifying the delta) modifying the 'query' (this is error prone).
There is a namespace ${dataimporter.delta. } which can be used
in this query. For example, select * from tbl where
id=${dataimporter.delta.id}.
