[~dwysakowicz] The flinksql client creates a MySQL data source, and the mysql field is biginteger. When the query is executed in the SQL client, it will go to getLong(int pos) in the GenericRowData code block, resulting in Caused by: java.lang.RuntimeException: java.math.BigInteger cannot be cast to java.lang.Long reports an error; check the source code and find it is a forced conversion; how to solve it,
