Constructor Detail

SFResultSet

public SFResultSet(SnowflakeResultSetSerializableV1 resultSetSerializable,
                   SFBaseStatement statement,
                   boolean sortResult)
            throws SQLException

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

The constructor will initialize the ResultSetMetaData.

Parameters:

resultSetSerializable - result data after parsing

statement - statement object

sortResult - true if sort results otherwise false

Throws:

SQLException - exception raised from general SQL layers

SFResultSet

public SFResultSet(SnowflakeResultSetSerializableV1 resultSetSerializable,
                   Telemetry telemetryClient,
                   boolean sortResult)
            throws SQLException

This is a minimum initialization for SFResultSet. Mainly used for testing purpose. However, real prod constructor will call this constructor as well

Parameters:

resultSetSerializable - data returned in query response

telemetryClient - telemetryClient

Throws:

SQLException

next

public boolean next()
             throws SFException,
                    SnowflakeSQLException

Advance to next row

Overrides:

next in class SFBaseResultSet

Returns:

true if next row exists, false otherwise

Throws:

SFException

SnowflakeSQLException
