I have 4 tables"

team
ID
NAME

TeamProperties
ID
TEAMID
NAME

teamRole
ID
TEAMID
TEAMROLEID

roleCandidate
ID
ROLEID

Team is the main table
TeamProperties joins to the Team table by ID-TEAMID
roleCandidate joins to the teamRole table by TEAMROLEID-ID
teamRole joins to the team table by TEAMID-ID

I need to delete all reference in the TeamProperties, teamRole, roleCandidate and to these table that belong to a certain team. All I have is the ID for the Team table. Can't get my head wrapped around it

Short answer: Delete from each table where TEAMID = YourValue
Longer answer: Create foreign keys on each child table to the Team table that have a cascading delete defined. Delete from Team where TEAMID = YourValue.
