My question is related to populating my SQL query values from Excel/VBA.  In my query I have two types of inputs, one for a date, another for a city or list of cities.  The date is working just fine and is populated in Excel as 'YYYY-MM-DD.  I can do the same with a single city as 'MIAMI.  What I can't figure out is how I properly populate multiple cities

I'm trying to parametrize a stored procedure, which takes one input string parameter and use it in the where clause in dynamic cursor.
The following snippet works with one parameter but when the list is like "US,GE", then it fails..
