Subject [jira] [Created] (CAMEL-7653) camel-sql endpoint oracle failure
Date Thu, 31 Jul 2014 09:45:39 GMT
Jo Geraerts created CAMEL-7653:
----------------------------------

             Summary: camel-sql endpoint oracle failure
                 Key: CAMEL-7653
                 URL: https://issues.apache.org/jira/browse/CAMEL-7653
             Project: Camel
          Issue Type: Bug
          Components: camel-sql
    Affects Versions: 2.12.0
            Reporter: Jo Geraerts


I use the sql endpoint against oracle, however the {{DefaultSqlPrepareStatementStrategy}}
uses {{PreparedStatement.setObject}} to set all the named parameters. With most jdbc drives
this works fine except for oracle. Oracle throws an ORA-17004 exception stating an invalid
column type. 

My route looks like this

{code}
from("{{ktn.stkbal.in")
                .routeId("KTN.StkBal")
                .onCompletion().onCompleteOnly()
                    .to("seda:generatestockbalancereport")
                .end()
                .setHeader("ts",constant(new Timestamp(new Date().getTime())))
                .split().tokenizeXML("product","stockPicture").streaming()
                    .setHeader("ean",xpath("/st:product/@ean").resultType(String.class).namespaces(KTNConstants.STOCK_NAMESPACES))
                    .setHeader("available", xpath("/st:product/st:available").resultType(Integer.class).namespaces(KTNConstants.STOCK_NAMESPACES))
                    .setHeader("blocked",xpath("/st:product/st:blocked").resultType(Integer.class).namespaces(KTNConstants.STOCK_NAMESPACES))
                    .to("sql:insert into stockbalance(ean,available,blocked,picturets) values
(:#ean,:#available,:#blocked,:#ts)?dataSourceRef=hybrisDataSource");
{code}

And from our dear oracle i get
{code}

{code}

As workaround i extended the {{DefaultSqlPrepareStatementStrategy}} and override {{populateStatement}}.
It leverages springs {{ArgumentPreparedStatementSetter}} to do the right thing.  

{code}
@Override
    public void populateStatement(PreparedStatement ps, Iterator<?> iterator, int expectedParams)
throws SQLException {
        final Object[] args = new Object[expectedParams];
        int i = 0 ;
        while (iterator != null && iterator.hasNext()) {
            args[i]=iterator.next();
            i++;
        }
        final ArgumentPreparedStatementSetter setter = new ArgumentPreparedStatementSetter(args);
        setter.setValues(ps);
    }
{code}
