Birt Report Input Parameter Default Value Dynamically set

Migrateduser

<p>I have created a BIRT Report which asks for Start Date and End date in Input Parameter. The input parameter is of type text. Now I want to show the default value in from MYSQL Database. I have created a dataset also for that. But I don't know how to set the default of text Input parameter dynamically. Every time when I run BIRT Report it should show the default value from the database. Please anyone can help!</p>
