Setting a field value when multiple records exist

Hi Everyone,

I have a question on how to set a field value in multiple records where there is a specific key, when a  condition is meet within multiple records.

I have a table 'A', it contains 4 fields:

I will have multiple records with the same TEAM_NAME(key). I want to set the TEAM_STATUS to 'Y' in each team record, only when ALL of the individual PLAYER_STATUS for that team is 'Y'.

Thanks in advance.

update your_table t1
set team_status = 'Y'
where not exists (select 1 from your_table t2 where t1.team_name = t2.team_name and player_status != 'Y')

momi_sabag's answer is appropriate for your current table definition, but generally speaking your data model does not seem adequate for the requirements. You clearly have two entities: team and player, which asks for at least two separate tables.
