Hi,

 

I need to pass a Guid value (from SQLServer) as an optional parameter.

If parameter has a value then data has to be filtered by that value.

 

But I don't know how to do it, I get a database error.

 

    Parameter type is String. Optional.

 

    In filter expert error is here:

            {MyTable.Id} = {?MY_PARAMETER}

   

    I have not foud how to convert string to guid.

    Is there any other way to do it?

 

Thank you.
