Method Detail

createDriverResultSet

ResultSet createDriverResultSet(Field[] fields,
                              List<byte[][]> tuples)
                                throws SQLException

Create a synthetic resultset from data provided by the driver.

Parameters:

fields - the column metadata for the resultset

tuples - the resultset data

Returns:

the new ResultSet

Throws:

SQLException - if something goes wrong

createResultSet

ResultSet createResultSet(Query originalQuery,
                        Field[] fields,
                        List<byte[][]> tuples,
                        ResultCursor cursor)
                          throws SQLException

Create a resultset from data retrieved from the server.

Parameters:

originalQuery - the query that generated this resultset; used when dealing with updateable resultsets

fields - the column metadata for the resultset

tuples - the resultset data

cursor - the cursor to use to retrieve more data from the server; if null, no additional data is present.

Returns:

the new ResultSet

Throws:

SQLException - if something goes wrong

executeWithFlags

boolean executeWithFlags(String sql,
                       int flags)
                         throws SQLException

Execute a query, passing additional query flags.

Parameters:

sql - the query to execute (JDBC-style query)

flags - additional QueryExecutor flags for execution; these are bitwise-ORed into the default flags.

Returns:

true if there is a result set

Throws:

SQLException - if something goes wrong.

executeWithFlags

boolean executeWithFlags(CachedQuery cachedQuery,
                       int flags)
                         throws SQLException

Execute a query, passing additional query flags.

Parameters:

cachedQuery - the query to execute (native to PostgreSQL)

flags - additional QueryExecutor flags for execution; these are bitwise-ORed into the default flags.

Returns:

true if there is a result set

Throws:

SQLException - if something goes wrong.

executeWithFlags

boolean executeWithFlags(int flags)
                         throws SQLException

Execute a prepared query, passing additional query flags.

Parameters:

flags - additional QueryExecutor flags for execution; these are bitwise-ORed into the default flags.

Returns:

true if there is a result set

Throws:

SQLException - if something goes wrong.
