Internet Explorer on Linux??

You mostly want to check for web page compatibility with IE if you're doing some web app stuff. So whats the solution if you prefer to use a linux distro rather than Windoz??

Enter ies4linux. ies4linux installs IE binaries over Wine. Wine is an Open Source implementation of the Windows API on top of X and Unix. ies4linux has a script which will download the IE setup files right from the microsoft site, and install over Wine. The best part is that you can install multiple versions of IE as well ;)

Circular dependency between Tables in SQL

Update: Added a new way to solve the problem

Q) How had to create Tables with a circular dependency between them. Like

CREATE TABLE A (
....A_ID INT,
....PRIMARY KEY A_ID,
....B_FK INT,
....FOREIGN KEY B_FK
....REFERENCES B(B_ID)
);


CREATE TABLE B (
....B_ID INT,
....PRIMARY KEY B_ID,
....A_FK INT,
....FOREIGN KEY A_FK
....REFERENCES A(A_ID)
);

... now this will not work as during create, table B does not exist

A) So one solution is ...

CREATE TABLE A (
....A_ID INT,
....PRIMARY KEY A_ID
);

CREATE TABLE B (
....B_ID INT,
....PRIMARY KEY B_ID,
....A_FK INT,
....FOREIGN KEY A_FK
....REFERENCES A(A_ID)
);

ALTER TABLE A ADD COLUMN B_FK INT AFTER A_ID;
ALTER TABLE A ADD FOREIGN KEY B_FK REFERENCES B(B_ID);

A little bit of cheating does the trick :)



A) Another mysql specific solution is to use the FOREIGN_KEY_CHECKS variable.

mysql> SET FOREIGN_KEY_CHECKS = 0;
mysql> SOURCE dump_file_name;
mysql> SET FOREIGN_KEY_CHECKS = 1;

In the dump_file_name, tables can be created in any order without checking of Foreign Key constraints. So we can create tables with circular depenndencies
