Analytical Functions in oracle explained with real examples
 
25:24
This video explains analytical functions and how they are implemented in real projects. Analytical functions are somewhat similar to aggregate functions,but they offer much more. Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function. I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions. You can find the sample problems along with dataset in the below link. http://www.internshipsfromhome.com/oracle-analytical-functions-ddl-and-dml/

Oracle LISTAGG Function
 
04:57
https://www.databasestar.com/oracle-listagg/ The Oracle LISTAGG function allows you to aggregate or combine string values from multiple rows into a single row. For example, it turns this data: FIRST_NAME Adam Brad Carrie Into this data: FIRST_NAME Adam, Brad, Carrie The same data is shown, but it’s in one row and not multiple. It’s a valuable string manipulation function, and once you know what it is and how it works, you’ll be able to use it in your queries as needed. So what does it look like? The function is: LISTAGG ( measure_expr [, delimiter]) WITHIN GROUP (order_by_clause) [OVER query_partition_clause] These parameters are: measure_expr: This is a column or expression that you want to concatenate the values of. In the example above, it was the first_name column. Mandatory. delimiter: This is the character between each of the measure_expr values. Optional, the default is a comma. order_by_clause: This is the order that the values from the measure_expr are listed. Mandatory. query_partition_clause: This allows you to use LISTAGG as an analytic function, allowing you to show LISTAGG in groups for different rows. One thing to be aware of is that the output of the Oracle LISTAGG function is limited to 4,000 bytes. If you get more than this, you’ll receive an error. The most common way around this that I’ve seen is to write a custom function and use a CLOB. Watch the video to find out more and see some examples. For more information about the Oracle LISTAGG function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-listagg/

Oracle CAST Function
 
03:23
https://www.databasestar.com/oracle-cast/ The Oracle CAST function allows you to convert one data type to another. It’s similar to the TO_NUMBER, TO_DATE, and TO_CHAR functions, but allows for more functionality, including converting to many other data types. The syntax of the CAST function is: CAST( {expr | MULTISET (subquery) } AS type_name ) The structure of this function is different to other functions, because it uses the word AS to separate parameters rather than a comma. You can run this function like many other functions, on a single row, which would look like this: CAST( expr AS type_name ) Or, you can run it as though it’s a subquery, using the MULTISET feature: CAST( MULTISET (subquery) AS type_name ) The parameters of the CAST function are: - expr (mandatory choice): This is the value or expression that is to be converted to another data type. - MULTISET (optional): This keyword indicates that the subquery results will return multiple rows, and are then CAST into a collection value. If this is omitted, and the subquery returns multiple rows, it will only return a single row. - subquery (mandatory choice): This is the subquery that can be run to be converted into a collection data type. - type_name (mandatory): This is the Oracle data type that the expr or subquery will be converted to. There are several data types that are compatible with the CAST function, both for converting from and to. You can find the full list in the article mentioned below. For more information about the Oracle CAST function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-cast/

Oracle TO_TIMESTAMP_TZ Function
 
01:43
https://www.databasestar.com/oracle-timezone-functions/ The Oracle TO_TIMESTAMP_TZ function can be confusing, but we’ll explain it in this video. This function allows you to convert a string value into a TIMESTAMP WITH TIME ZONE value. A TIMESTAMP WITH TIME ZONE value is a type of DATE, but has a few components: - A date, including day, month, and year - A time, including hours, minutes, and seconds - A time zone, which is the number of hours and minutes difference from GMT This is a useful data type because it allows you to store dates in different time zones, and allow users in other time zones to see the data in a way that makes sense to them. The time zone part is the difference from GMT. This means that a “+7:00” is 7 hours ahead of GMT (e.g. Bangkok) and “-5:00” is 5 hours behind GMT (e.g. US Eastern Standard Time). The syntax of the TO_TIMESTAMP_TZ function is: TO_TIMESTAMP_TZ ( input_string [, format_mask] [, nls_param] ) The input_string parameter is the string you want to convert. The format_mask is where you specify the format of the input_string parameter. This is so you can specify the input_string in a variety of formats, and just use this format_mask to indicate which format it is in. The nls_param parameter is another optional parameter, and allows you to specify the returning language of the month and day names. For more information on the Oracle TO_TIMESTAMP_TZ function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-timezone-functions/
Views: 91 Database Star
Oracle CURRENT_TIMESTAMP Function
 
02:37
https://www.databasestar.com/oracle-date-functions/ The Oracle CURRENT_TIMESTAMP function will display the current date and time in the session time zone. Just like the CURRENT_DATE function, it uses the session time zone, which is where you logged in from. This could be different to the database time zone. The syntax of the CURRENT_TIMESTAMP function is: CURRENT_TIMESTAMP ( [precision] ) The return type of this function is TIMESTAMP WITH TIME ZONE. The precision parameter is optional, and it lets you specify the number of fractional seconds to return. If this is omitted, it uses the default of 6. It’s different to the SYSTIMESTAMP function, because CURRENT_TIMESTAMP returns the session timezone, and SYSTIMESTAMP returns the database time zone. So, if I’m logging in from Melbourne, Australia, and the database is in London, England, then the CURRENT_TIMESTAMP will return a date and time that’s 10 hours ahead of SYSTIMESTAMP, and in a different time zone. It may be on the same day, or it could be a different day, depending on when I run the function. You can perform arithmetic on this function just like any other date value (e.g. CURRENT_TIMESTAMP - 7 for 7 days ago). However, it might be better to use interval data types so you can keep the original data type. For more information about the Oracle CURRENT_TIMESTAMP function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-date-functions/

last_value function in sql server 2008 sql server last_value function returns incorrect data sql server last_value function example sql server last_value function with partition example LAST_VALUE function in SQL Server In this video we will discuss LAST_VALUE function in SQL Server. LAST_VALUE function Introduced in SQL Server 2012 Retrieves the last value from the specified column ORDER BY clause is required PARTITION BY clause is optional ROWS or RANGE clause is optional, but for it to work correctly you may have to explicitly specify a value Syntax : LAST_VALUE(Column_Name) OVER (ORDER BY Col1, Col2, ...) LAST_VALUE function not working as expected : In the following example, LAST_VALUE function does not return the name of the highest paid employee. This is because we have not specified an explicit value for ROWS or RANGE clause. As a result it is using it's default value RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW. SELECT Name, Gender, Salary, LAST_VALUE(Name) OVER (ORDER BY Salary) AS LastValue FROM Employees LAST_VALUE function working as expected : In the following example, LAST_VALUE function returns the name of the highest paid employee as expected. Notice we have set an explicit value for ROWS or RANGE clause to ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING This tells the LAST_VALUE function that it's window starts at the first row and ends at the last row in the result set. SELECT Name, Gender, Salary, LAST_VALUE(Name) OVER (ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS LastValue FROM Employees LAST_VALUE function example with partitions : In the following example, LAST_VALUE function returns the name of the highest paid employee from the respective partition.

Oracle SQL MEDIAN Function Examples and Guide
 
03:28
https://www.databasestar.com/median-mean-mode-in-oracle/ In this video, you’ll learn what the term “median” means, and how to generate an Oracle SQL median value. What is median? It’s the middle value in a list of values, after the values have been sorted in ascending order. It’s kind of like an average, but it’s different, as the average finds the total of the values divided by the number of values and will often not be one of the values in the list. Median will usually be the value in the list that is the middle point. So, how can you calculate the median in Oracle SQL? We use a function called MEDIAN. And in this video, I’ll show you how to use the function and see some examples. For more information on the MEDIAN function, including the SQL used in this video, read the related article here: https://www.databasestar.com/median-mean-mode-in-oracle/

COALESCE Function in SQL ORACLE Query With Example
 
03:53
ORACLE/PLSQL: COALESCE FUNCTION The Oracle/PLSQL COALESCE function returns the first non-null expression in the list. If all expressions evaluate to null, then the COALESCE function will return null. The syntax for the Oracle/PLSQL COALESCE function is: coalesce( expr1, expr2, ... expr_n ) PARAMETERS: expr1 to expr_n are the expressions to test for non-null values. EXAMPLE: The COALESCE function can be used in Oracle/PLSQL. You could use the coalesce function in a SQL statement as follows: SELECT COALESCE( address1, address2, address3 ) result FROM suppliers; The above COALESCE function is equivalent to the following IF-THEN-ELSE statement: IF address1 is not null THEN result := address1; ELSIF address2 is not null THEN result := address2; ELSIF address3 is not null THEN result := address3; ELSE result := null; END IF; The COALESCE function will compare each value, one by one. Lets apply the same to emp table. We have some NULL values in comm and mgr columns. but not in any other columns. So lets take a example for this 2 columns. COALESCE(comm,mgr,sal) Here if comm is null, function returns mgr value. If mgr is null it returns sal value! Query used in video: SELECT ename,comm,mgr,sal,COALESCE(comm,mgr,sal) result FROM emp;

SQL with Oracle 10g XE - Using the DISTINCT Function
 
02:52
In this video I use the DISTINCT function to list the values of a column from a query and remove the duplicate listings. When using the DISTINCT function be sure to have parenthesis around the column you wish to perform the function on. You can't use the * to list all the columns in the SELECT command, so you will need to write the columns you wish to see out. If you want to rename the column you created with the function use the keyword AS on the SELECT line. This video is part of a series of videos with the purpose of learning the SQL language.

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;
