Re: [PERFORM] Related to Inserting into the database from XML file
I am little bit confused between whether to insert XML file as it is or insert data from the XML file in to a particular field from thetable. I will decided it depending upon the performance factor For storing the XML file as it is, will there be any performance cause if compared to storing values in particular fields. If performance issue is not there for XML formats then we have around 12 to 13 tables, if we store XML data as it is in all tables then is there any generic format for select query?
