使用字段查询时，报EOFException异常，比如下面一条语句
select \* from rtb_daily_report_audience where campaign_id=89085;

Start by reproducing the reported query, `select * from rtb_daily_report_audience where campaign_id=89085`, and capture the complete error context around ERROR 1003 and EOFException. Trace the Java database-proxy handling for field queries; done means this query completes without EOFException and the regression is covered by a test.
