Can I use variable in my OLE DB Command?
Like this:
update
mst.TRANSIT_DIM
set
TRANS_END_DT = @[User::v_PROC_END_DT],
ACTIVE_ROW_FL = 0,
UPDATE_DT = GetDate()
where
TRANSIT_NUM = ?

I don't believe you can unless you are setting up your SQL Statement to be from a variable and you build the variable ahead of the OLE DB Command step.

I believe you can do it like this:

update

mst.TRANSIT_DIM

set

TRANS_END_DT = ?,

ACTIVE_ROW_FL = 0,

UPDATE_DT = GetDate()

where

TRANSIT_NUM = ?

And now you have 2 parameters in the command and parameter 0 would have the @[User::v_PROC_END_DT] assigned to it.

I don't really understand where these

Param_0

Param_1

Param_2

in OLE DB Command are coming from.

Is it whenever you have "?" in your command it creates a new Param?

OK. But then I would need to have a Derived Column

"cnv_PROC_END_DT" = @[User::v_PROC_END_DT] so that I can connect my Param_0 to something?

Right?

I thought I could eliminate this Derived Column step and

assign @[User::v_PROC_END_DT] value to "TRANS_END_DT" directly inside the command.

Please see my attachment.

Connecting [cnv_PROC_END_DT] to Param_0

and [TRANSIT_NUM] to Param_1

does the job but I do it blindly.

I don't understand how TRANS_END_DT gets updated properly

because I don't connect it to anything in GUI.
