--------------------------------
Summary: JdbcIO 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
The actual use case is such that I am connecting to Oracle via JDBC making the
query: "select 1 from dual".
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"
