 ### 4.Query for Outputting Sorted Data Using ‘Order By’
 > This query orders the results with respect to the attribute which is referenced to using “Order By” – so for example, if that attribute is an integer data type, then the result would either be sorted in ascending or descending order; likewise, if the data type is a String then the result would be ordered in alphabetical order.
 
-`SELECT EMP_ID, LAST_NAME FROM EMPLOYEE
-WHERE CITY = 'Seattle' ORDER BY EMP_ID;`
+```
+SELECT EMP_ID, LAST_NAME FROM EMPLOYEE
+WHERE CITY = 'Seattle' ORDER BY EMP_ID;
+```
 
 > The ordering of the result can also be set manually, using “asc ” for ascending and “desc” for descending.
 
-`SELECT EMP_ID, LAST_NAME FROM EMPLOYEE_TBL
-WHERE CITY = 'INDIANAPOLIS' ORDER BY EMP_ID asc;`
+```
+SELECT EMP_ID, LAST_NAME FROM EMPLOYEE_TBL
+WHERE CITY = 'INDIANAPOLIS' ORDER BY EMP_ID asc;
+```
 
 ### 5.Query for Outputting Sorted Data Using ‘Group By’
 > The ‘Group By’ property groups the resulting data according to the specified attribute.
 
-`SELECT Name, Age FROM Patients WHERE Age > 40 
-GROUP BY Age ORDER BY Name;`

 ### 9. ALTER TABLE
 > ALTER TABLE lets you add columns to a table in a database.
 
-`ALTER TABLE table_name 
-ADD column_name datatype;`
+```
+ALTER TABLE table_name 
+ADD column_name datatype;
+```
 
 ### 10. AND
 > AND is an operator that combines two conditions. Both conditions must be true for the row to be included in the result set.
 
-`SELECT column_name(s)
+```
+SELECT column_name(s)
 FROM table_name
 WHERE column_1 = value_1
-AND column_2 = value_2;`
+AND column_2 = value_2;
+```
 
 ### 11. AS
 > AS is a keyword in SQL that allows you to rename a column or table using an alias.
 
-`SELECT column_name AS 'Alias'
-FROM table_name;`
+```
+SELECT column_name AS 'Alias'
+FROM table_name;
+```
 
 ### 12. BETWEEN
 > The BETWEEN operator is used to filter the result set within a certain range. The values can be numbers, text or dates.
 
-`SELECT column_name(s)
+```
+SELECT column_name(s)
 FROM table_name
-WHERE column_name BETWEEN value_1 AND value_2;`
+WHERE column_name BETWEEN value_1 AND value_2;
+```
 
 ### 13. CASE 
 > CASE statements are used to create different outputs (usually in the SELECT statement). It is SQL's way of handling if-then logic.
-`SELECT column_name,
+```
+SELECT column_name,
   CASE
     WHEN condition THEN 'Result_1'
     WHEN condition THEN 'Result_2'
     ELSE 'Result_3'
   END
 FROM table_name;
-`
+```
+
+### 14. CREATE TABLE
+> CREATE TABLE creates a new table in the database. It allows you to specify the name of the table and the name of each column in the table
+```
+CREATE TABLE table_name (
+  column_1 datatype, 
+  column_2 datatype, 
+  column_3 datatype
+);
+```
+
+### 15. DELETE
+> DELETE statements are used to remove rows from a table.
+```
+DELETE FROM table_name
+WHERE some_column = some_value;
+```
+
+### 16. HAVING 
+> HAVING was added to SQL because the WHERE keyword could not be used with aggregate functions.
+```
+SELECT column_name, COUNT(*)
+FROM table_name
+GROUP BY column_name
+HAVING COUNT(*) > value;
+```
+
+### 17.  INNER JOIN
+> An inner join will combine rows from different tables if the join condition is true.
+```
+SELECT column_name(s)
+FROM table_1
+JOIN table_2
+ON table_1.column_name = table_2.column_name;
+```
+
+### 18. INSERT
+> INSERT statements are used to add a new row to a table.
+```
+INSERT INTO table_name (column_1, column_2, column_3) 
+VALUES (value_1, 'value_2', value_3);
+```
+
+### 19. IS NULL/ IS NOT NULL
+> IS NULL and IS NOT NULL are operators used with the WHERE clause to test for empty values.
+```
+SELECT column_name(s)
+FROM table_name
+WHERE column_name IS NULL;
+```
+
+### 20. LIKE
+> LIKE is a special operator used with the WHERE clause to search for a specific pattern in a column.
+```
+SELECT column_name(s)
+FROM table_name
+WHERE column_name LIKE pattern;
+```
+
+
 
 
 ### 9. Query for Creating a View
 > A view is a tailored table that is formed as a result of a query. It has tables and rows just like any other table. It’s usually a good idea to run queries as independent views because this allows them to be retrieved later to view the query results, rather than computing the same command every time for a particular set of results.
 
-`CREATE VIEW Failing_Students AS
+```
+CREATE VIEW Failing_Students AS
 SELECT S_NAME, Student_ID
 FROM STUDENT
-WHERE GPA > 40;`
+WHERE GPA > 40;
+```
 
 ### 10. Query for Listing all Views
 > This query lists all the views available in the schema.
