Select Names from table which have vowels

Problem Query the list of CITY names from table which have vowels (i.e., a , e , i , o , and u ) as both their first and last characters. Your result cannot contain duplicates. Input Format The STATION table is described as follows: Field Type ID NUMBER CITY VARCHAR2(21) STATE VARCHAR2(2) LAT_N NUMBER LONG_W NUMBER STATION where LAT_N is the northern latitude and LONG_W is the western longitude. MYSQL select distinct city from station where (city like 'a%' or city like 'e%' or city like 'i%' or city like 'o%' or city like 'u%' ) and ( city like '%a' or city like '%e' or city like '%i' or city like '%o' or city like '%u' )

Q- What will be the result of the query below? Explain your answer and provide a version that behaves correctly. select case when null = null then 'Yup' else 'Nope' end as Result; Ans-This query will actually yield “Nope”, seeming to imply that null is not equal to itself! The reason for this is that the proper way to compare a value to null in SQL is with the is operator, not with = . Accordingly, the correct version of the above query that yields the expected result (i.e., “Yup”) would be as follows: select case when null is null then 'Yup' else 'Nope' end as Result;

Methods of Rank Rows in SQL Server: ROW_NUMBER(), RANK(), DENSE_RANK() and NTILE()

SQL Server provides us with a number of window functions that help us to perform calculations across a set of rows, without the need to repeat the calls to the database. Unlike the standard aggregate functions, the window functions will not group the rows into a single output row, they will return a single aggregated value for each row, keeping the separate identities for those rows. The Window term here is not related to the Microsoft Windows operating system, it describes the set of rows that the function will process. One of the most useful types of window functions is Ranking Window Functions that are used to rank specific field values and categorize them according to the rank of each row, resulting in a single aggregated value for each participated row. There are four ranking window functions supported in SQL Server; ROW_NUMBER(), RANK() , DENSE_RANK() and NTILE() . All these functions are used to calculate ROWID for the provided rows window in ...
