I have three tables
1) Country - columns (PKCountryId(Pr imaryKey),Count ryName)
2)State - Columns (PKStateId(Prim aryKey),StateNa me,FKCountryId( ForeignKey))
3)Address Details -Columns(PKAddre ssId(PrimaryKey ),......,...... .,FKCountryId(F oreignKey),FKSt ateId(ForeignKe y),............ ......)
I developed relationship like this. I have three relations
1)FK_AddressDet ails_Country(Be tween Country table and AddressDetails table of PKCountryId in Country Table and FKCountryId in AddressDetails in AddressDetails Table)
2) FK_AddressDetai ls_State (Between State table and AddressDetails table of PKStateId in State Table and FKStateId in AddressDetails in AddressDetails Table)
3)FK_State_Coun try(Between State Table and Country Table of PKCountryId in Country Table and FKCountryId in State Table)
I have the requirement like this...when i delete a country from countrytable it has to delete in state table and AddressDetails table...I not able to develop the relation ship when i do using Database Diagrams with Insert and delete specification as DeleteRule Set to Cascade ....i am getting this error with UpdateRule set to NoAction
This is the error ............... ......in the dialog box displaying
- Unable to create relationship 'FK_AddressDeta ils_Country'.
Introducing FOREIGN KEY constraint 'FK_AddressDeta ils_Country' on table 'AddressDetails ' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.
Could not create constraint. See previous errors.
This is important for me

I have what I call a composite table. Can't recall what they called it in
database class, but it's where you take the PK of two different tables, and
make a new table consisting of only those two fields. That's for
normalization purposes, to resolve a many-to-many situation.
Anyway, I have three dropdowns, which I intentionally gave the same name. I

I'm making my first ever database for my program.
I understand the concept of one to many relationships but
fail to see the advantage of using a secondary key over a
primary one.
I have a lot of tables and link them together by one key
the CaseKey.
What is the disadvantages of this method? Why should I
include more detailed item keys (e.g an arraylist of
customer credit items would be stored in the

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
