> Key: FLINK-12309
> URL: https://issues.apache.org/jira/browse/FLINK-12309
> Project: Flink
> Issue Type: Bug
> Components: Connectors / JDBC
> Reporter: FaxianZhao
> Priority: Major
> Labels: pull-request-available, stale-major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When we use JDBCAppendTableSinkBuilder#setParameterTypes() config the JDBC
> types, it bind BasicTypeInfo#FLOAT_TYPE_INFO to java.sql.Types#FLOAT.
> But JDBCOutputFormat#writeRecord will force cast the float value to double,
> so it will throw ClassCastException like "java.lang.Float cannot be cast to
> java.lang.Double".
