how to check that my table is parent table or child table before trucating
568189Mar 29 2007 — edited Mar 29 2007Hi:
say i wanted to trucate a table .the table might be a parent table or might be a child table.if its a child table then there wouldnt be any problems in truncating.
if its a parent table the i believe i would have to diable all the foreign key constraints from the child table referring to the parent table ..my question is
1. i have a table say ABC. before truncating how do i find out if table ABC is a parent table or not?
2.lets assume i tried to truncate the table ABC and i got the error saying that disable the foreign keys on the child table referring to the parent table ABC.
in my schema there are say 50 tables.out of which there might be 10 odd child tables referring to my parent table ABC.
so my question here would be how do i specifically find out these 10child tables referring to the Parent table ABC so that i can disable the foreign keys on the child tables.
Thanks 4 ur time in reading this and hopefully i think u wld give me a solution!!
