Answer:
Following are the code to this question:
/*using the select statement, that selects column name from the table blog.posts */
SELECT blog.posts.user_id, blog.posts.body, users.name/*column name user_id, body, name*/
FROM blog.posts/* use table name blog.posts*/
RIGHT OUTER JOIN users ON blog.posts.user_id = users.id;/*use right join that connect table through user_id*/
Explanation:
In the structured query language, RIGHT JOIN is used to recovers from both the right side of the table both numbers, although the left table has no sets. It also ensures that even if the 0 (null) documents are linked inside this left table, its entry will always return the outcome row, but still, the number of columns from its left table will be NULL.
In the above-given right join code, the select statements used that selects the column names "user_id, body, and the name" from the table "blog. posts" and use the right join syntax to connect the table through the id.
Explanation:
The difference between entry condition loop is and exit - condition loop is that the entry condition loops first checks the condition to enter the loop body if the condition true then the loop body is executed otherwise loop body is not executed while the exit-condition loops first executes the loop body and then the condition for the loop is checked.
There are three loops in C that are as following:-
- For
- While
- Do While
Among these three loops While and For loops are entry condition loops and Do While loop is exit condition loop.
For example:-
for(int i=0;i<10;i++)
{
printf("%s","John Doe\n");
}
If the initial value of i should have been 10 then loop body didn't had executed.
int i=0;
while(i<4)
{
printf("%s","John Doe\n");
}
If you try to run this while loop nothing will print on the screen because the condition is false.So the compiler will not enter the loop body and will skip over it.
int i=5;
do{
printf("%s","John Doe\n");
}while(i<4);
Even if the condition is false.You will see that the John doe have been printed one time on the screen because first the body is executed then the condition is checked.
