title: Oracle, save/map csv string to a table using utl_file and external tables
body: <p>I use a pl/sql procedure calling a webservice. This webservice returns me a large csv-string which I hold in a clob. Since I do not want to parse the csv by foot, I thought of using external tables. So what I need to do is storing the csv data in a corresponding table.</p>
  
  <p>What I am doing at the moment is, that I store the clob using utl_file. the stored file is defined in a external table. Ok, when I am the only user this works very well. But since DBs are multiuser I have to watchout if someone else is calling the procedure and overwriting the external table data source file. What is the best way avoid a mess in table data source? Or what is the best way to store a cvs-sting into a table?</p>
  
  <p>Thanks
