Consequences of multiple FK's from same column to multiple tables @ypercube: good point, that should be an answer. |

Consequences of multiple FK's from same column to multiple tables @dezso: Right, once the FK's BA and CB are created CA becomes redundant -- just not sure if that redundancy is a problem. |

Consequences of multiple FK's from same column to multiple tables @AlexKuznetsov: there isn't a practical problem, and adding FK's is just about the limit of what is possible at this stage. The FK from C to A(aid) already exists, so the question is remove it and replace with a FK from C to B(aid) or just add it on top? I don't think it makes a practical difference. |

Security and Performance implications of “View Server State” @PeterCarter: +1 for the DoS and common wait states. I was hoping for something a bit more encompassing, but at least it's a solid potential risk. |

Security and Performance implications of “View Server State” @ThomasStringer: the question isn't about necessity, it's about risk. To put it in monetary terms, you may know what additional risks this would expose your servers to, and so be able to say no to a penny, and yes to a million dollars. I don't, but I want to. |

Security and Performance implications of “View Server State” I understand Least Privileges, I in fact referenced it in my question -- I am looking for how to evaluate need vs risk. If 50% of the views cause the server to grind to a halt or it allows the user to view confidential information, then the need would have to be significant. |

UDF in check constraint — downside? The application is where you try to do things right, the database is where you can say "this is wrong, don't allow it". |

Why aren't primary key / foreign key matches used for joins? @onedaywhen: I was referring to the syntax "natural join table_name (columnlist)", which I don't belive is ANSI 92, as an extension which allows you to join on more than one columns provided that both tables have them. |

UDF in check constraint — downside? @AlexKuznetsov: I read your blog, and have verified your general conclusion, but your query is incorrect for your stated goals (only one row with b if any row with b has 1), you need a second query to check for the number of rows with b's (otherwise adding a row with c2=0 works). I think the "workaround" of including all columns that are evaluated in the UDF in the parameter list should fix the general problem, but it's definitely a potential "gotcha" that you have to be aware of if you're going to use a UDF in a check constraint. |
