ResultSet

public ResultSet(ResultSet.ResultType resultType,
                 @Nullable
                 Long nextToken,
                 org.apache.flink.table.catalog.ResolvedSchema resultSchema,
                 List<org.apache.flink.table.data.RowData> data)

getResultType

public ResultSet.ResultType getResultType()

Get the type of the results, which may indicate the result is EOS or has data.

getNextToken

@Nullable
public Long getNextToken()

The token indicates the next batch of the data.

When the token is null, it means all the data has been fetched.

getResultSchema

public org.apache.flink.table.catalog.ResolvedSchema getResultSchema()

The schema of the data.

The schema of the DDL, USE, EXPLAIN, SHOW and DESCRIBE align with the schema of the TableResult.getResolvedSchema(). The only differences is the schema of the `INSERT` statement.

The schema of INSERT:

 | column name | column type | comments |
 +-------------+-------------+----------+
 |   job id    |    string   |          |
 +- -----------+-------------+----------+
