Robert Bradshaw updated BEAM-8897:
----------------------------------
Priority: P2 (was: P3)
> JdbcIO.readRows issue when type is Numeric
> ------------------------------------------
>
> Key: BEAM-8897
> URL: https://issues.apache.org/jira/browse/BEAM-8897
> Project: Beam
> Issue Type: Bug
> Components: io-java-jdbc
> Affects Versions: 2.16.0
> Environment: Java 8
> Reporter: Mark Gates
> Priority: P2
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> The actual use case is such that I am connecting to Oracle via JDBC making
> the query: "select 1 from dual". If I try this on real data with a Number
> type column the same issue occurs.
> The number type results in an exception. Example:
> {code:java}
> PCollection<Row> row = p.apply(
> JdbcIO.readRows()
>
> .withDataSourceProviderFn(JdbcIO.PoolableDataSourceProvider.of(configuration))
> .withQuery("select 1 as t1 from dual")
> .withFetchSize(10000)
> .withOutputParallelization(true));
> row.apply(ParDo.of(new DoFn<Row, Row>() {
> @ProcessElement
> public void processElement(@Element Row row, OutputReceiver<Row> out,
> ProcessContext pc) {
> System.out.println(row.getSchema().toString() + " : " +
> row.toString());
> out.output(row);
> }
> }));
> p.run().waitUntilFinish();
> {code}
> Exception:
> Exception in thread "main"
