Step 1 :  Change in Parameter "Default Value Expression". Step 2 :  Change the Report's "Dataset and Query Editor" Property with below keywords with correct syntax.

Step 1 : Create a executable report with a query where there are no parameters at first. In current example I will be using " select * from address " .    Step 2 :   Assuming filter on Field "City", here we will use following code in query.

Check or uncheck "Is for Prompting" property as value mentioned in "Default Value Expression" is set to "Dallas" . Hence ResultSet will only return records with city which matches value as Dallas.   Step 3 :  Finally 1st type of Parameter $P{...} returns desired output as shown in be...
