> ExecuteSQL converts BigDecimal to strings in Avro
> -------------------------------------------------
>
> Key: NIFI-2048
> URL: https://issues.apache.org/jira/browse/NIFI-2048
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 0.6.1
> Reporter: Bryan Bende
> Priority: Minor
> Fix For: 1.3.0
>
>
> Some JDBC drivers (Oracle is one of them) return NUMBER columns as
> BigDecimal. NiFi then turns that into a string in the Avro that is produced.
> This happens in JdbcCommon when creating the schema:
> {code}
> case DECIMAL:
> case NUMERIC:
> builder.name(meta.getColumnName(i)).type().unionOf()
> .nullBuilder().endNull().and().stringType().endUnion().noDefault();
> {code}
> Then later when getting the value of the column to add to the Avro record:
> {code}
> } else if (value instanceof BigDecimal || value instanceof BigInteger) {
> rec.put(i - 1, value.toString());
> }
> {code}
> It looks like Avro has support for Decimal types and we should look into
> using this:
> https://avro.apache.org/docs/1.7.7/spec.html#Logical+Types
