Count in an Update statement - How do you do it

Toad for Oracle
1

I have a select statement with a count that works just fine.
But when I add the update statement I get en error stating that my count field is an invalid identifier

–Update the Follow Up Cnt field
Update schuck1.seibel_contacts@cepd.devl.corp.cname.com
Set follow_up_cnt = acnt where acnt in
(select mdm2.mdm_cust_id, s_cont_id, count(ACON.RELATION_TYPE_CD) acnt
from sds_ifo_s_contact scon,
sds_ifo_s_asset_con acon,
( Select *
from sds_ifo_s_asset
where type_cd = ‘Device Set’
and status_cd = ‘Active’) asset,
schuck1.seibel_contacts@cepd.devl.corp.cname.com MDM2
where scon.row_id = mdm2.s_cont_id
and scon.row_id = acon.contact_id
and acon.asset_id = asset.row_id
Group by mdm2.mdm_cust_id, s_cont_id
)
;

Morning Kimberly,

You appear to be asking Oracle to compare acnt with (mdm_cust_id,
s_cont_id, acnt) - in other words your IN has three columns but you are
comparing it with one.

I suspect you might get away with it by :

Set follow_up_cnt = acnt where acnt in
(select acnt from
(select mdm2.mdm_cust_id, s_cont_id, count(ACON.RELATION_TYPE_CD) acnt
...)
)

In other words, extracting the acnt column from the inline.

However, don't quote me as it's early AM and my first coffee has not had
time to energise my system. :wink:

Alternatively, you can do this (sometimes) :

update (select statement)
Set whatever = something,
whatever_else = somethihng_else
where ....;

Resulting in something like:

Update

(select mdm2.mdm_cust_id, s_cont_id, count(ACON.RELATION_TYPE_CD) acnt
from sds_ifo_s_contact scon,
sds_ifo_s_asset_con acon,
( Select *
from sds_ifo_s_asset
where type_cd = 'Device Set'
and status_cd = 'Active') asset,
schuck1.seibel_contacts@cepd.devl.corp.cname.com MDM2
where scon.row_id = mdm2.s_cont_id
and scon.row_id = acon.contact_id
and acon.asset_id = asset.row_id
Group by mdm2.mdm_cust_id, s_cont_id
)

Set follow_up_cnt = acnt where acnt in (list of acnts to be updated);

Or in the alternative, if you need to compare all three fields, you could use
the structure:

Select *

From dual

Where (1,2,3) in (select 1,2,3 from dual);
