По сути, CASE является SQL оператором, а ключевые слова WHEN и THEN позволяют задавать несколько условия для проверки, теоретически количество этих условий может быть бесконечным. Выражение с оператором CASE имеют две формы записи, но в любом случае условное выражение в SQL завершается ключевым словом END. */ -- 1 вариант CASE WHEN первое условие THEN первое возвращаемое значение WHEN второе условие THEN второе возвращаемое значение … WHEN энное условие THEN энное возвращаемое значение [ELSE возвращаемое значение, если условие не будет выполнено] END -- 2 вариант CASE первое значение, которое хотим проверить WHEN первое значение, с которым сравниваем THEN первое значение, которое возвращаем WHEN второе значение, с которым сравниваем THEN второе значение, которое возвращаем … WHEN энное значение, с которым сравниваем THEN энное значение, которое возвращаем [ELSE возвращаемое значение, если условие не будет выполнено] END -- Для начала рассмотрим два простых примера CREATE TABLE booltable (a,b); INSERT INTO booltable VALUES (1,0); SELECT * FROM booltable; -- 1 вариант выражения CASE в SQL SELECT CASE WHEN a==1 THEN 'true' ELSE 'false' END as typeColA, CASE WHEN b THEN 'true' ELSE 'false' END as typeColB FROM booltable; -- 2 вариант выражения CASE в SQL SELECT CASE a WHEN 1 THEN 'true' ELSE 'false' END AS boolA, CASE b WHEN 1 THEN 'true' ELSE 'false' END AS boolB FROM booltable;

CASE Function( IF..THEN..ELSE) in SQL ORACLE Query With Example
 
04:03
ORACLE/PLSQL: CASE STATEMENT The Oracle/PLSQL CASE statement has the functionality of an IF-THEN-ELSE statement. Starting in Oracle 9i, you can use the CASE statement within a SQL statement. The syntax for the Oracle/PLSQL CASE statement is: CASE [ expression ] WHEN condition_1 THEN result_1 WHEN condition_2 THEN result_2 ... WHEN condition_n THEN result_n ELSE result END --------- ARGUMENTS: expression is optional. It is the value that you are comparing to the list of conditions. (ie: condition_1, condition_2, ... condition_n) condition_1 to condition_n must all be the same datatype. Conditions are evaluated in the order listed. Once a condition is found to be true, the CASE statement will return the result and not evaluate the conditions any further. result_1 to result_n must all be the same datatype. This is the value returned once a condition is found to be true. NOTE: If no condition is found to be true, then the CASE statement will return the value in the ELSE clause. If the ELSE clause is omitted and no condition is found to be true, then the CASE statement will return NULL. You can have up to 255 comparisons in a CASE statement. Each WHEN ... THEN clause is considered 2 comparisons. Lets apply this function on emp table. Emp table has 3 dept numbers like 10,20 and 30. So if I want to display the different dept names based on ID, I have to use IF THEN ELSE condition. IF deptno=10 THEN "DEPT1" ELSE deptno=20 THEN "DEPT2" ELSE deptno=30 THEN "DEPT3" This entire IF block can be achived using CASE. CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'NO DEPT' END; Query used in Video: select empno,ename,deptno,CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'No Dept' END from emp;

In case you miss the SQL functions intro video you can find the link in the description below. First let's see what these functions are. Upper (): This function takes a parameter converts it into uppercase and returns the new string. Initcap (): this function also takes parameter and converts the initial letter of or parameter into uppercase and returns the new string. Lower (): This function takes a parameter converts it into lowercase and returns the new string. Ok let's do some practical For this practical we will be using 2 tables First is dual table Which is a dummy table provided by oracle? And I have created another table again by the name of example. This will be our second table. Let's start with SQL function upper ( ); SELECT upper('hello world') FROM dual; As you can see I have used "hello world" completely in lowercase as parameter to SQL upper function. Execute it. Here, our result has given us a completely new hello world string which is in uppercase. Similarly you can also use SQL upper function to perform other DML Let's try This time we will work on our second table EXAMPLE; insert into example values (upper('manish')); first parentheses for values and second for SQL function upper. Let's check the result. As you can see here inserted value is in upper case. Lets compare it with simple insert query Insert into example values ('manish'); Execute it, i think now it's clear that when we perform simple insert DML the inserted value will be the same you provide. Similarly let's try SQL function initcap(); SELECT initcap('hello world') FROM dual; As you see here in result the initial letters of string hello world are in uppercase. Let's do the insert query insert into example values (initcap('hello world')); initial letters of string also are in uppercase. Let's try SQL function lower(); This time we have to write our hello world in all caps. SELECT lower('HELLO WORLD') FROM dual; Execute String totally in lower case. Similarly you can user SQL function lower in other DML like insert and all.

DECODE and CASE in Oracle
 
02:00
DECODE and CASE statements in Oracle both provide a conditional construct. Databases before Oracle 8.1.6 had only the DECODE function. CASE was introduced in Oracle 8.1.6 as a standard, more meaningful and more powerful function. Everything DECODE can do, CASE can. There is a lot else CASE can do though, which DECODE cannot. DECODE performs an equality check only. CASE is capable of other logical comparisons such as != etc. It takes some complex coding – forcing ranges of data into discrete form – to achieve the same effect with DECODE. An example of putting employees in grade brackets based on their salaries. This can be done elegantly with CASE. Follow the steps given in video : https://youtu.be/QPxKAufB_eo and Learn How to use DECODE and CASE in oracle

There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

We will be using Countries table in this example.
