Didn't see this board - I posted this on the Dreamweaver general section - should have been here...

I am struggling with a problem in Dreamweaver MX.

I have a database application dealing with event types that I'm trying to write a front end for. I have created a SQL query that selects events based on start date AND multiple event types ( ie MTG for "Meeting", CON for "Conference" etc. )

I am trying to query a SQL Anwywhere database and I have built a query in Infomaker ( Client Server report writer ) that accepts a date and a STRING ARRAY as arguments.

For example:

SELECT ev200_event_master.ev200_evt_id,
ev200_event_master.ev200_evt_desc,
ev200_event_master.ev200_mi_date,
ev200_event_master.ev200_mo_date,
ev200_event_master.ev200_evt_type
FROM ev200_event_master
WHERE ( ev200_event_master.ev200_evt_type in ( :Event_type ) ) AND
( ev200_event_master.ev200_mi_date >= :Start_date )

ORDER BY ev200_event_master.ev200_mi_date ASC

Pretty simple ? You don't have to know much SQL to see how easy this is. It works fine. It accepts a simple string array like MTG,CON and returns both types. The problem is that in Dreamweaver, no matter how I construct the query - I can only retrieve ONE event type with the following syntax ( essentially the same )

SELECT EV200_EVT_ID, EV200_EVT_DESC, EV200_MI_DATE, EV200_MO_DATE, EV200_EVT_TYPE
FROM gpcb.EV200_EVENT_MASTER
WHERE EV200_MI_DATE >= ? AND EV200_EVT_TYPE IN (?)
ORDER BY EV200_MI_DATE ASC

I am testing the query directly with the advanced query builder in Dreamweaver MX and it works for ONE type ( ie 'MTG') but if I try to pass the string array THE WAY I KNOW THE DATABASE WANTS IT - it doesn't work.

Why?

I can't see why this is so difficult. It's just supposed to pass text to the database engine...

Somebody must have an answer for this?
