-------------------------------
Description:
This issue aims to introduce {{executeStatement}} which synchronously executes
the given single statement immediately, and returns the execution result.
{code:java}
/**
* Synchronously execute the given single statement immediately and the
statement can be DDL/DML/SHOW/DESCRIBE/EXPLAIN/USE.
* If the statement is translated to a Flink job, the result will be returned
until the job is finished.
*
* @return result for SHOW/DESCRIBE/EXPLAIN, the affected row count for `DML`
(-1 means unknown), or a string message ("OK") for other statements.
* @throws Exception which occurs during the execution.
*/
ResultTable executeStatement(String statement) throws Exception;
/**
* A ResultTable is the representation of the statement execution result.
*/
public interface ResultTable {
/**
* Get the schema of ResultTable.
*/
TableSchema getResultSchema();
/**
*Get the result contents as an iterable rows.
*/
Iterable<Row> getResultRows();
}
