Create Table Statement and Constraints Assignment

Table Creation and Data insertion:
Create following Tables with required constraints (as mentioned) using SQL DDL.

Table: Student

*sid* (int) Primary Key	*sname* Varying Char (10)	*sbranch* Char(5)	*sage* (int) (not greater than 25)
1001	Kamal	IT	18
1004	Yogesh	IT	17
1011	Mani	CSE	20
1022	Farooq	EEE	21
1027	Girija	CSE	24
1030	Mousmi	CSE	22
1036	Rajanish	EEE	21
1052	Praneet	EEE	21
1059	Joseph	CSE	17
1063	Lahiri	IT	21

Table: Course

*cid* (int) PK	*Cname* (chars 4 and unique)	*units* (int)
10	OS	3
20	DBMS	4
30	CNW	5
40	PHY	3

Table: StudentCourse

*stid* PK1 and FK to sid of student	*cno* PK2 and FK to cid of course
1001	20
1001	30
1004	10
1004	20
1004	30

1027	30
1036	10
1036	30
1036	20
1059	10

Solution

DDL: Data Definition Language
 - create 
 - alter 
 - drop

DML: Data Manipulation Language 
 - select 
 - insert 
 - update 
 - delete 

Microsoft SQL Server
How to add a "Check Constraint" on a column:
CREATE TABLE CountryList (
  Id INT IDENTITY PRIMARY KEY,
  CountryName VARCHAR(255) NOT NULL,
  CountryPopulation INT CHECK(CountryPopulation > 0)
)

ALTER TABLE student ADD CONSTRAINT CheckSage CHECK (sage > 25);

Adding a "Foreign Key"
CREATE TABLE Orders (
    OrderID int NOT NULL,
    OrderNumber int NOT NULL,
    PersonID int,
    PRIMARY KEY (OrderID),
    FOREIGN KEY (PersonID) REFERENCES Persons(PersonID)
); 

Creating a 'Composite Primary Key'
Create table StudentCourse ( stid  integer FOREIGN Key REFERENCES Student (sid) , 
cno integer Foreign Key References Course (cid),
PRIMARY KEY (stid, cno) ); 

A mistake that students make...
Create table StudentCourse ( stid  integer Primary Key FOREIGN Key REFERENCES Student (sid), 
cno integer PRIMARY key Foreign Key References Course (cid) );

Msg 8110, Level 16, State 0, Line 1
Cannot add multiple PRIMARY KEY constraints to table 'StudentCourse'. 

Oracle DB

SQL> create table student_ashish_12345 (sid int primary key, sname varchar2(10), sbranch char(5), sage int constraint stud_sage_ck check (sage <= 25));

SQL> create table course_ashish_12345 (cid int primary key, cname char(4) unique, units int);

SQL> create table studentcourse_ashish_12345 (stid int, cno int, constraint sc_pk primary key(stid, cno), constraint sc_fk1 foreign key (stid) references bits_student (sid), constraint sc_fk2 foreign key (cno) references bits_course (cid));

SQL> select table_name from tabs where table_name like '%ASHISH_12345';

Stock Market Lesson (Stock Averaging)

Stock Averaging

You buy 10 stocks for 100 Rs on Day 1. 
Price of stock is 10 Rs.
10 Days later lets say, stock price comes down to 8 INR and you buy 10 more stocks. 
The price of stock today is 8 Rs.
Total number of shares with you is 20.
For a price of: (10 + 8) * 10
Then average 'Stock Price' for your stock for you is: 9 Rs

Now, let's us, you buy 10 stocks for 100 Rs. For Rs 10 per share.
10 days later, stock price rises to 15 INR. You buy 10 more shares for Rs 15 per share.
Total number of shares with is now 20.
Then average 'Stock Price' for your stock is: 12.5 INR 

% If your stock is going up, you have to keep averaging it. 

% Always average your Winners. Never average your Losers. 

Other Tips

% When markets are volatile, it is hard to detect individual good or bad stocks.

% When markets are going up, it is easier to go up with the tide but it is hard to justify why a particular low-profile stock has gone up or gone down.

% You should always compare your stock with market benchmarks such as Nifty50 and Sensex.

% Good stocks shoot up like anything when the market benchmarks are going up by like 1% (which is considered a high fluctuation for Nifty50 and Sensex).

Debugging SSH Setup for two RHEL systems

ISSUE: SLAVE1 IS NOT ABLE TO CONNECT WITH SLAVE2 VIA SSH WITHOUT PASSWORD PROMPT.

IP AND HOSTNAME MAPPING:
  10.74.19.50    MASTER
  10.138.22.103  SLAVE1
  10.85.62.107   SLAVE2

COMMANDS FOR DOING SSH SETUP:

  1) sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT
  2) sudo reboot
  3) ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ""
  4) ssh-copy-id -i ~/.ssh/id_rsa.pub projadmin@SLAVE2
  5) ssh-copy-id -i ~/.ssh/id_rsa.pub admin@SLAVE1
  6) ssh-copy-id -i ~/.ssh/id_rsa.pub admin@MASTER

~~  ~~  ~~

Command "ssh-copy-id" is used to copy your SSH public key to remote server for password less authentication.

MESSAGE YOU GET WHEN SSH KEYS ARE ALREADY PRESENT ON THE REMOTE SYSTEM:

  (base) [projadmin@SLAVE2 ~]$ ssh-copy-id -i ~/.ssh/id_rsa.pub admin@SLAVE1
    /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/projadmin/.ssh/id_rsa.pub"
    /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
    
    /usr/bin/ssh-copy-id: WARNING: All keys were skipped because they already exist on the remote system.
                    (if you think this is a mistake, you may want to use -f option)

~~  ~~  ~~

LAST RESORT:

  Deleting the everything in the directory: projadmin@SLAVE2:/home/projadmin/.ssh
  Copying public key only again from slave1: (base) [admin@SLAVE1 ~]$ ssh-copy-id -i ~/.ssh/id_rsa.pub projadmin@SLAVE2
  The issue still exists. Not able to SSH slave2 from slave1 without password prompt.
