                                            @Nullable
                                            Meta.StatementHandle h,
                                            Meta.Signature signature,
                                            int resultSetType,
                                            int resultSetConcurrency,

                                              throws SQLException

Throws:

SQLException

newResultSet

AvaticaResultSet newResultSet(AvaticaStatement statement,
                            Meta.Signature signature,
                            TimeZone timeZone,
                            Iterable<Object> iterable)
                              throws SQLException

Creates a result set. You will then need to call AvaticaResultSet.execute() on it.

If signature implements MetaImpl.WithIterable we do not need to execute; we can use pre-canned data. This mechanism is used for metadata requests such as getTables.

Parameters:

statement - Statement

signature - Prepared statement

timeZone - Time zone

iterable - Iterable over rows in result, or null if an execute/fetch is required

Returns:

Result set

Throws:

SQLException

newDatabaseMetaData

AvaticaDatabaseMetaData newDatabaseMetaData(AvaticaConnection connection)

Creates meta data for the database.

Returns:

Database meta data

newResultSetMetaData

ResultSetMetaData newResultSetMetaData(AvaticaStatement statement,
                                     Meta.Signature signature)
                                       throws SQLException

Creates meta data for a result set.

Parameters:

statement - Statement

signature - Prepared statement

Returns:

Result set meta data

Throws:

SQLException
