Hi

Is it possible to change a crystal reports query at design or runtime?

for example, I have a single report which can be used for a multitude of reports, with just the change of on parameter.  Like, employee birthdays, if I want to get all employees who have a DOB in january, the query is the same for every other month aside from the date...

I am using MS Access as the datasource in a c#2010 winforms application

I tried using [month] in the query as a parameter, but that accepts a numeric value.. which is ok, but I would prefer for the user to have a dropdown list of months with January, February and so on... and for the query to feed from that... can this be done?

Cheers

I'm assuming you mean you are using the Add Command feature to base the report on a sql command. (If not you will have to explain what you mean by 'change the crystal reports query')

In the dialog where you create the sql Command you have an option to create a parameter.

Say you create a new parameter of type string called MyMonth and set it to default to January.
 You can then then incorporate the parameter into the sql command....

like...

Select * from Orders where Format([Order Date], "mmmm")='{?myMonth}'

In addition having created the parameter this way,  you can then go into the parameter fields in the main Crystal Field Explorer and modify the parameter - add a list of month names as the possible values.
