Multi-Select the Easy Way

Multi-Select Parameters Available in 2.2Builds an array of values

Often Used with SQLConstrain query to range of valuesWhere state in (‘MN’, ‘NC’, ‘CA’)

5


Implementation Techniques

JavaScript Event HandlersDataSet Property Binding

Two Issues Maintenance

(query & expression)SQL Injection

6


SQL Injectionselect * from orders where state in (?)

? = “ ‘MN’); drop database;select * from dual where 1 in (‘1’ ”

select * from orders where state in (‘MN’);drop database;select * from dual where 1 in (‘1’)

DON’T

DO

THIS

7


Parameter Binding

Supported by JDBC and all DatabasesStops SQL Injection Attacks

select * from orders wherestate in (?,?,?)

Each parameter value requires a binding

8


Can BIRT Do This?

AbsolutelyDesign Engine API

Read QueryTextFind Parameter Names / ValuesModify SQL Text to add ‘?’ Add Parameter Binding to DataSet

9


Can BIRT Do This Easily?

AbsolutelyUse standard SQL Syntax Use ScriptFunctionExtension point

Build your own functionsExpose those functions in the UINew to 2.3.1

10


Standard SQL Syntax

Select * From OrdersWhere 0=0-- and status in (‘MS:parameterName’)

11


Use the ScriptFunctionExtension

The easiest BIRT extension pointExtremely useful Many simpler applications

Combining the DEAPI and ScriptFunctions is more difficult.

Don’t Let these examples scare you away.
