SELECT statement:
It is used to retrieve information from the table or
Syntax:
SELECT * FROM table_Name;
WHERE clause:
“WHERE” statement is used limit the number of rows. For example: Consider a table “FTable” that has two columns named “FruitName” and “Color”. “WHERE” clause is used when there is a need to display the entire FruitName whose color is Red.
SELECT * FROM FTable WHERE color = 'red';
When the above statement is executed, red colored fruits get displayed.
Inner join:
The “inner join” keyword is to select the matching records from two tables. The syntax of “inner join” is as follows:
Syntax:
SELECT column_name FROM table1 INNER JOIN table2 ON table1.column_name=table2.column_name;
“AND” operator:
The operator used to check two or more conditions using single query. The “AND” operator returns “true” when two conditions are satisfied in the query.
ORDER BY Clause:
SQL contains “ORDER BY” clause in order to sort rows. The values get sorted in ascending as well as descending order. The keyword used to sort values in ascending order is “ASC” and for descending order is “DESC”. By default, it sorts values by ascending order.
Syntax:
SELECT column_Name1, column_Name2 FROM table_Name ORDER BY column_Name2;

Based on the subnet mask 255.255.255.0, no bits were borrowed from the host portion, meaning 8 bits remain in the host portion. Using the formula 2^h – 2 (where h represents the number of host bits), we get 2^8 - 2 = 254 hosts. 8 bits --> 17 & 252 128 64 32 16 | 8 4 2 1 0 0 0 1 0 0 0 1 --> 17+ 1 1 1 1 1 1 0 0 --> 252 0 0 0 1…arrow_forwardWhich of the following opens when you click the launcher in the Size group on the Ribbon?
