newResultSet

AvaticaResultSet newResultSet(AvaticaStatement statement,
                              QueryState state,
                              Meta.Signature signature,

                       throws SQLException

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

Parameters:

statement - Statement

state - The state used to create this result set

signature - Prepared statement

timeZone - Time zone

firstFrame - Frame containing the first (or perhaps only) rows in the result, or null if an execute/fetch is required

Returns:

Result set

Throws:

SQLException

newDatabaseMetaData

AvaticaSpecificDatabaseMetaData 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
