A way to "SELECT constraints FROM table"

is there any way to get the contraints or indexes of a table doing a SELECT QUERY?

I am using a VC++ application to do some changes on a Access DB and there is a contraint that as a random name... This would help me to find the constraint name automaticaly and change drop it as I want

hope someone knows a way to do thisSELECT * FROM MSysRelationships-PatP|||Thank you very very very much... you don't know how much did you help me :)

Finally someone gave me a good answer to my problem and it WORKS :D
