DB2 data manipulation

developerWorks®ibm.com/developerWorksThe input stream is used to store the retrieved BLOB in a file calledclonedredbookcover.jpg. To retrieve CLOBs, much of the syntax is similar to that ofretrieving a BLOB.FILE FILEOUTPUT = ;NEW;FILE("C:\\CLONEDREDBOOKABSTRACT.TXT");FILEOUTPUTSTREAM FO = ;NEW; FILEOUTPUTSTREAM(FILEOUTPUT);INPUTSTREAM IS = CLOB.GETASCIISTREAM();INT C;WHILE; ((C = IS.READ()) != -1)FO.WRITE(C);FO.CLOSE();In the Java snippet above, the stored CLOB was materialized to a new file namedclonedredbookabstract.txt. This is done by using the getAsciiStream method of theCLOB. Just like you did when retrieving the BLOB, you assign the stream to anInputStream, which then is read from, and in turn write what was read to theFileOutputStream.Section 9. ConclusionSummaryIn this tutorial, you learned many concepts on data manipulation strategies. Youlearned how to:• Access the data in multiple tables and change them• Use MQTs• Use SQL routines• Use common tables• Use cursors• Use CLOB and BLOB data types• Program with transactionsWhile this tutorial focused on concepts, further tutorials in this series describe all theinterfaces used to perform data manipulation.DB2 data manipulationPage 22 of 25© Copyright IBM Corporation 1994, 2007.
