Constructor Detail

SnowflakeResultSetV1

public SnowflakeResultSetV1(SFBaseResultSet sfBaseResultSet,
                            Statement statement)
                     throws SQLException

Constructor takes an inputstream from the API response that we get from executing a SQL statement.

The constructor will fetch the first row (if any) so that it can initialize the ResultSetMetaData.

Parameters:

sfBaseResultSet - snowflake core base result rest object

statement - query statement that generates this result set

Throws:

SQLException - if failed to construct snowflake result set metadata

Constructor takes a result set serializable object to create a sessionless result set.

Parameters:

sfBaseResultSet - snowflake core base result rest object

resultSetSerializable - The result set serializable object which includes all metadata to create the result set

Throws:

SQLException - if fails to create the result set object

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

Specified by:

getResultSetSerializables in interface SnowflakeResultSet

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 it fails to get the ResultSetSerializable objects.
