Question : Cursor in SP, cursor not open error

I've a trigger on table SynchReceiver to redirect insert records to another two tables,
SynchMessage and SynchDeliver only if BUSSUNITNBR field has value.  

The schema for the three tables are:

SynchReceiver

ReceiverID
RetPlantID
Status
Content
BUSSUNITNBR


SynchMessage

MessageID
RetPlantID
DateTime
IsDelivered
Content

SynchDeliver

DeliverID
RetPlantID
Status
Content
MessageID
BUSSUNITNBR

And my testing script is

INSERT INTO SynchReceiver
      (RetPlantID, Status, Content, BUSSUNITNBR)
VALUES      ('101', 0, '101new', '901902')



here's my trigger with a cursor in it.  When I tested it, I got error message in query analyzer:
Cursor is not open.
The statement has been terminated.

I also tested the select statement for the cursor, which is working fine and I got two records back.

Answer : Cursor in SP, cursor not open error

Your close and deallocate statements use the underscore character and your declare, open and fetches don't.

OPEN     retplantscursor

CLOSE retplants_cursor
