Interface SnowflakeResultSet

All Known Implementing Classes:

SnowflakeResultSetV1

public interface SnowflakeResultSet

This interface defines Snowflake specific APIs for ResultSet

Method Summary

Modifier and Type	Method and Description
String	getQueryID()
List<SnowflakeResultSetSerializable>	getResultSetSerializables(long maxSizeInBytes) Get a list of ResultSetSerializables for the ResultSet in order to parallel processing
QueryStatus	getStatus() This function retrieves the status of an asynchronous query.

Method Detail

getQueryID

String getQueryID()
           throws SQLException

Returns:

the Snowflake query ID of the query which generated this result set

Throws:

SQLException

getStatus

QueryStatus getStatus()
               throws SQLException

This function retrieves the status of an asynchronous query. An empty ResultSet object has already been returned but the query may still be running. This function can be used to poll to see if it is possible to retrieve results from the ResultSet yet. See Client/src/main/java/net/snowflake/client/core/QueryStatus.java for the list of all possible query statuses. QueryStatus = SUCCESS means results can be retrieved.

Returns:

QueryStatus enum showing status of query

Throws:

SQLException

getResultSetSerializables

List<SnowflakeResultSetSerializable> getResultSetSerializables(long maxSizeInBytes)
                                                        throws SQLException

Get a list of ResultSetSerializables for the ResultSet in order to parallel processing

Parameters:

maxSizeInBytes - The expected max data size wrapped in the ResultSetSerializables object. NOTE: this parameter is intended to make the data size in each serializable object to be less than it. But if user specifies a small value which may be smaller than the data size of one result chunk. So the definition can't be guaranteed completely. For this special case, one serializable object is used to wrap the data chunk.

Returns:

a list of ResultSetSerializables

Throws:

SQLException - if fails to get the ResultSetSerializable objects.
