title: how to check if a key of a record is used in other tables as foreign key (sql)?
body: <p>I have a table that its primary key "ID" field is used in many other table as foreign key.</p>
  
  <p>How can I realize that a record from this table (for example first record "ID = 1") is used in other table?</p>
  
  <p>I don't want to select from all other tables to understand it cause tables are so many and relations either. I searched for a solution, there were no working solutions or I got it wrong. Please help. </p>
