Fastload Skips Header when using from Java - response (2) by tomnolan

By the way, here is a code snippet to illustrate how to dynamically prepend a column header line to a CSV InputStream. The basic idea is to use a SequenceInputStream to combine the column header line with the actual data.
 

String sHeaderLine = "column1,column2,column3" + System.getProperty ("line.separator") ;
InputStream isHeader = new ByteArrayInputStream (sHeaderLine.getBytes ("ASCII")) ;
InputStream isData = new FileInputStream ("data.csv") ;
InputStream isCombined = new SequenceInputStream (isHeader, isData) ;

 
Instead of binding the InputStream containing the data values to the JDBC FastLoad CSV PreparedStatement, your application would bind the combined InputStream.
