Assume I have one table:
id name comment
1 stupid blabla
2 idiot blabla
These row has been referenced by other table..... Then I add one row to
that table, so the table become:
id name comment
1 stupid blabla
2 idiot blabla
3 dumb bleble
The row with id "3" has not been referenced by other table because I
have just insert it ( it is still fresh ).... How do I know for sure
that "this row" or "that row" has or has not been referenced by other
table???? Of cource I can test it by trying to delete it.... if it has
been referenced, the delete command will fail, and if it has not been
referenced the delete command will success.....
Thank you.
