Answer:
Select commands would return all the rows and columns in the table.
Explanation:
In the database management system, it consists of one or more table. To handle this table it provides the concept of SQL(Structured Query Language). It is a programming language that design, manage, store data into the relational database. It is case sensitive language. In the SQL many commands used for handle table data, it returns all rows and columns from the table.
Syntax of select command can be given as:
Select * from tablename;
Example:
select * from ProductCategory;
returns all the data from the table.
In select command, we will also return select data by using condition
SELECT column1 [, column2, ...]
FROM tablename
WHERE condition
In the conditional clause we use these operators that can be given as:
= Equal, > Greater than, < Less than, >= Greater than equal to, <= Less than equal to, != Not equal to.
Insert Method
it is used to returns an integer that speaks to the area of the substring inside the string.
Answer:
public: virtual void print()=0;
Explanation:
An abstract class contains a pure virtual function. Pure virtual class cannot be instantiated but it can be subclassed and the subclass can provide an implementation of the function.
A virtual function declaration in the class is preceded by the virtual keyword. For example, virtual void print();
A pure virtual function declaration is followed by '=0;'
public: virtual void print()=0;
Based on the given spreadsheet, the database function that needs to be entered into cell I6 to find the average salary of all full-time employees is =AVERAGEIFS(D5:D34,B5:B34,"FT",C5:C34,">=1")
<h3>What does the AverageIfs formula find?</h3>
You can use the AverageIfs formula to find the average of a specific group of numbers from a spreadsheet based on the shared categories that these numbers fall under.
After typing in the =AverageIfs function, you then input the range from which the category will be specified. In this case that is D5:D34. The next entry would be the range the category is picked from which is B5:B34. The function will be FT for Full time workers.
Then use C5:C34 to find out the number of dependents that are equal to or greater than 1.
The digit returned is the average salary of all full-time employees.
