  • enterpriseddb stored procedure

    Hi,
    I am running application on top of enterprisedb data base.
    I am trying to call stored procedure by using spring API.
    Here is the code:
    private class UpdateFreuqenciesCounterStoredProcedure extends StoredProcedure {
    private final static String PROCEDURE_NAME = "Da_Querygateway_Pg.update_frequencies";

    private final static String PARAM_CUSTOMER_ID = "customer_id";
    private final static String PARAM_EVENT_DATE = "event_date";

    private final static String PARAM_ID_ARRAY = "custAdFreqTbl";
    private final static String PARAM_FREQUENCY_ID_ARRAY = "freqIdTbl";
    private final static String PARAM_FREQ_TYPE_ID_ARRAY = "freqTypeIdTbl";
    private final static String PARAM_FREQ_INVERVAL_ARRAY = "freqMinIntervalTbl";
    private final static String PARAM_AD_ID_ARRAY = "adIdTbl";



    public UpdateFreuqenciesCounterStoredProcedure(DataSource ds) throws SQLException {
    super(ds,PROCEDURE_NAME);
    declareParameter(new SqlParameter(PARAM_CUSTOMER_ID, java.sql.Types.BIGINT));
    declareParameter(new SqlParameter(PARAM_EVENT_DATE, java.sql.Types.TIMESTAMP));
    declareParameter(new SqlParameter(PARAM_ID_ARRAY,java.sql.Types.VARCHAR ));
    declareParameter(new SqlParameter(PARAM_FREQUENCY_ID_ARRAY,java.sql.Typ es.VARCHAR ));
    declareParameter(new SqlParameter(PARAM_FREQ_TYPE_ID_ARRAY, java.sql.Types.VARCHAR));
    declareParameter(new SqlParameter(PARAM_FREQ_INVERVAL_ARRAY, java.sql.Types.VARCHAR));
    declareParameter(new SqlParameter(PARAM_AD_ID_ARRAY, java.sql.Types.VARCHAR));
    compile();
    }

    public void execute(Long customerId, Date eventDate, List<Long> adIdList, List<CustomerAdFrequency> frequencyList) throws SQLException {
    HashMap<String, Object> paramters = new HashMap<String, Object>(7);

    StringBuffer adIdBuf = new StringBuffer();
    StringBuffer idBuf = new StringBuffer();
    StringBuffer freqTypeBuf = new StringBuffer();
    StringBuffer freqIntervalBuf = new StringBuffer();
    StringBuffer freqIdBuf = new StringBuffer();

    //int index = 0;
    for (Long adId: adIdList) {
    //adIdArray[index++] = adId;
    adIdBuf.append(','+ adId);
    }
    String adIdStr = adIdBuf.substring(1);

    //index = 0;
    for (CustomerAdFrequency adFrequency: frequencyList) {

    idBuf.append(','+ adFrequency.getId());
    freqTypeBuf.append(','+ adFrequency.getFrequency().getFrequencyType().getI d());
    freqIntervalBuf.append(','+ adFrequency.getFrequency().getMinimumIntreval());
    freqIdBuf.append(',' + adFrequency.getFrequency().getId());
    //index++;
    }

    String idStr = "";
    String freqTypeStr = "";
    String freqIntervalStr = "";
    String freqIdStr = "";
    if(idBuf.length()>0)
    idStr = idBuf.substring(1);
    if(freqTypeBuf.length() >0)
    freqTypeStr = freqTypeBuf.substring(1);
    if(freqIntervalStr.length() >0)
    freqIntervalStr = freqIntervalBuf.substring(1);
    if(freqIdStr.length() >0)
    freqIdStr = freqIdBuf.substring(1);

    paramters.put(PARAM_CUSTOMER_ID, customerId);
    paramters.put(PARAM_EVENT_DATE, eventDate);
    paramters.put(PARAM_ID_ARRAY, idStr);
    paramters.put(PARAM_FREQUENCY_ID_ARRAY,freqIdStr );
    paramters.put(PARAM_FREQ_TYPE_ID_ARRAY, freqTypeStr);
    paramters.put(PARAM_FREQ_INVERVAL_ARRAY, freqIntervalStr);
    paramters.put(PARAM_AD_ID_ARRAY, adIdStr);
    super.execute(paramters);
    }


    }

    When I am executing it I am getting an endless loop that prints the following:
    2008-08-05 18:02:30,354 INFO core.JdbcTemplate - Added default SqlReturnUpdateCount parameter named #update-count-xxx1
    2008-08-05 18:02:30,354 INFO core.JdbcTemplate - Added default SqlReturnUpdateCount parameter named #update-count-xxx2
    etc..
    It loops and doesn't execute the stored procedure.
    What can be the reason?
    Thanks.

    anybody?
    Where can I at least find list of data bases spring jdbc supports?

      There is a bug in the EnterpriseDB JDBC driver. I hit the same issue about a year ago and posted on their forum - see http://forums.enterprisedb.com/posts/list/1056.page. Doesn't seem as if they fixed the issue though. If you have a support contract you could try raising a support request.

      In the meantime you can use a custom JdbcTemplate for your StoredProcedure. Set the JdbcTemplate to skip the result processing - setSkipResultsProcessing(true) and then pass the JdbcTemplate in to the constructor instead of the DataSource.

      Spring supports using any JDBC driver that implements the JDBC 3.0 or later specifications.

        Thanks!
        One more question about enterprisedb: I couldn't figure out how to pass array to the stored procedure, I saw many Oracle examples that use Oracle's Array and ArrayDescriptor, but don't know how to do it without Oracle's APIs.
        I tried jdbcTemplate.execute("call procName {?,?}", new Object[]{arr1, arr2})
        but I got an exception that in or out parameters are not specified(something like this).
        Any hint will be welcome.
        Thanks again.
