问题
Please forgive my ignorance and poor SQL programming skills but I am normally a basic SQL developer.
I need to create a trigger off the insertion of data in one table to insert different data into another table.
Within this trigger I need to insert certain data into the new table based upon values within the newly inserted data from the original table. I am totally confused on this. i thought I would be creative and use a case statement within teh Values section but it is not working.
Can anyone please help me on this? (below is the code for the trigger that I have as of now)
INSERT INTO dbo.WebOnlineUserPeopleDashboard
(
ONLINE_USERACCOUNT_ID,
ONLINE_ROOMS_DIRECTORY,
ONLINE_ROOMS_LIST,
ONLINE_ROOMS_PLACEMENT,
ONLINE_ROOMS_MANAGEMENT,
ONLINE_MAILINGLIST_DIRECTORY,
ONLINE_MAILINGLIST_LIST,
ONLINE_MAILINGLIST_MEMBERS,
ONLINE_MAILINGLIST_MANAGER,
ONLINE_PEOPLESEARCH_DIRECTORY
)

Something like this?
