[JDBC] PreparedStatementImpl

[chernser]

Description

There are some issues:

• executeQuery() - Doesn't check if all parameters are set
• executeUpdate() - Doesn't check if all parameters are set
• setBytes(int parameterIndex, byte x[]) - Test ignored, implementation will incorrectly encode into string
• setObject(int parameterIndex, Object x, int targetSqlType) - target type is ignored
• setObject(int parameterIndex, Object x, SQLType targetSqlType) - target type is ignored
• setNString(int parameterIndex, String value) - no tests
• setNCharacterStream(int parameterIndex, Reader value, long length) - length seems ignored
• setObject(int parameterIndex, Object x, int targetSqlType, int scaleOrLength) - scaleOrLength ignored
• setObject(int parameterIndex, Object x, SQLType targetSqlType) - type ignored
