Ask TOM Office Hours: Fetching Single Rows in PL/SQL
 
33:25
Held on April 3 2018 An exploration of the nuances of fetching a single row. You have a number of implementation choices and it is definitely not a one-size-fits-all. Steven reviewed the most common options (implicit cursor (SELECT-INTO), explicit cursor, cursor FOR loop) and touched on dynamic SQL. He then answered questions about options for multi-row fetching, table operator and table functions and more. Here's a quick guide to the highlights: First 12 minutes: some philosophical musings and an overview of single row fetching 12:30 - Explicit Cursors 14:45 - Declaring records based on explicit cursors 16:15 - The benefits and drawbacks of the cursor FOR loop (for single row fetches) 19:42 - Multi-row fetching options 24:00 - Table operator and table functions 31:15 - Use LiveSQL as source of examples AskTOM Office Hours offers free, monthly training and tips on how to make the most of Oracle Database, from Oracle product managers, developers and evangelists. https://asktom.oracle.com/ https://developer.oracle.com https://cloud.oracle.com/en_US/tryit music: bensound.com

Data Con LA 2018 - Why use a columnar database for analytical workloads by Shane Johnson
 
32:28
Why use a columnar database for analytical workloads by Shane Johnson, Senior Director, MariaDB In this session, we’re going to discuss how columnar databases the improve performance and efficiency of analytical workloads. We’ll begin by explaining why transactional queries (e.g., return every column in a single row) benefit from row-based storage whereas analytical queries (e.g., return the aggregate of a single column in every row) benefit from column-based storage. We will walk through the storage and query processing architecture of MariaDB AX, an open source columnar database, to show how columnar databases work. In addition, we will show how massively parallel processing, combined with column-based storage, not only improves the performance and efficiency of analytical workloads, but scales to support interactive, ad hoc analytical queries on terabytes of data and billions of rows in real time.

In this video we learn how to include a single quote in our SQL text by "escaping" the quote. In SQL server single quotes are used to mark the beginning and end of a text string. However, if your text contains single quote, that poses an problem, if it is left alone it will be treated like a delimiter.

SQL String Functions PART  -- 1
 
17:23
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). ... The most basic example of a string function is the length(string) function. This function returns the length of a string literal.Scalar-valued UDFs are an easy way to define constant values to use in your database environment. You can pass field values as parameters into UDFs. You can nest scalar function calls. This means that you can pass a call to a scalar-valued function to another function or stored procedure.Numeric functions perform manipulation of numbers that normally are contained in a table column. ... Returns a numeric value, rounded to the specified length or precision. SIGN() SQL server, MySQL, Oracle, PostgreSQL. Returns the positive (+1), zero (0), or negative (-1) sign of a numeric expression.A stored function (also called a user function or user-defined function) is a set of PL/SQL statements you can call by name. Stored functions are very similar to procedures, except that a function returns a value to the environment in which it is called. User functions can be used as part of a SQL expression.Function must return a value but in Stored Procedure it is optional( Procedure can return zero or n values). Functions can have only input parameters for it whereas Procedures can have input/output parameters . ... Functions can be called from Procedure whereas Procedures cannot be called from Function,The CTE was introduced into standard SQL in order to simplify various classes of SQL Queries for which a derived table just wasn't suitable. ... Introduced in SQL Server 2005, the common table expression (CTE) is a temporary named result set that you can reference within a SELECT, INSERT, UPDATE, or DELETE statement.The isDate(string, string) function accepts two string arguments. It takes them, compares the first argument with the second as a pattern and, if the first string can be converted to a date which is valid within system value of locale , according to the specified pattern , the function returns true.printf does the same, treating %s as a pointer-to-string. In C, variables that are arrays become a pointer to the first element of the array when used as function arguments -- so your scanf() sees a pointer to memory (assuming "str1" is an array). SQL - Useful Functions SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. More items... SQL has many built-in functions for performing processing on string or numeric data. Following is the list of all useful SQL built-in functions − SQL COUNT Function - The SQL COUNT aggregate function is used to count the number of rows in a database table. SQL MAX Function - The SQL MAX aggregate function allows us to select the highest (maximum) value for a certain column. SQL MIN Function - The SQL MIN aggregate function allows us to select the lowest (minimum) value for a certain column. SQL - The SQL AVG aggregate function selects the average value for certain table column. SQL SUM Function - The SQL SUM aggregate function allows selecting the total for a numeric column. SQL SQRT Functions - This is used to generate a square root of a given number. SQL RAND Function - This is used to generate a random number using SQL command. SQL CONCAT Function - This is used to concatenate any string inside any SQL command. SQL Numeric Functions - Complete list of SQL functions required to manipulate numbers in SQL. SQL String Functions - Complete list of SQL functions required to manipulate strings in SQL. Returns a Unicode string with the delimiters added to make the input string a valid SQL Server delimited identifier. REPLACE. Replaces a sequence of characters in a string with another set of characters. REPLICATE. Repeats a string value a specified number of times.SQL. Character Functions with Examples. Character functions accept character inputs and can return either characters or number values as output. SQL provides a number of different character datatypes which includes – CHAR, VARCHAR, VARCHAR2, LONG, RAW, and LONG RAW.Aggregate Functions: Aggregates the values and return a single value, below is the list of some aggregate values in sql server. These functions are created by user in the system database, and we have 3 types of user define functions: Scalar Function. Inline Table-Valued Function.

This is the video in the series of Windowing functions in Spark. In this tutorial, we would understand the internals of First_value and Last_value functions in this lecture. Before that, if you have missed the first part of Windowing functions in spark SQL part 1 i.e. Lead and Lag functions, here is the link, https://www.youtube.com/watch?v=MViPRjaqfaA&t=3s These are inbuilt functions which operate on a set of rows and return a single value for each row from the underlying query. This can be very useful to simplify complex queries and break them down into logical components. To give you a brief idea of these windowing functions in spark, we will be using stock market data. You can download the sample stocks data from the link in the following, Dataset download link: https://drive.google.com/open?id=1nWGndnKxCNi5WKqPMBbrEhp4CBIWb7O- Commands link for First value and Last Value: https://drive.google.com/open?id=1jjtg26NkJURbfzGvZ1r-voCX0gFv1xwu Let's now understand the input(Dataset) and expected the output of First_value function. 1st column in this dataset is the date, 2nd column is the ticker which is nothing but the stock name, 3rd column is the open value of a stock, 4th column is the highest value of stock on a particular day, 5th column is the lowest value of stock on a particular day, 6th column is the closing value of stock, and the last column is the volume of the stocks on that particular day. In the sample output on the right-hand side of the screen. We have performed the query to retrieve ticker, date, high and derived column First_heigh. which is the value of high when ticker appears 1st time in the dataset.

How to : Use oracle sql: learning sql
 
08:49
Learn sql basics and start writing queries now SQL is shorthand for Structured Query Language. Oracle SQL is a language and not an application. It is a language that can be used to communicate with databases and analyze data. Before you use Oracle SQL, you need to understand what a database is. It’s a collection of data stored in an organized fashion. The data is stored in tables, in either a column or a row. Vertical data is called a column, and horizontal data is called a row. Oracle SQL is composed of keywords such as SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY. The 6 keywords mentioned above allow you to query a database and analyze its information. It's important that you understand these SQL basics during training. When you write a query, please remember to use the SQL keywords below in the order you see them. Learning SQL can be tricky but these tips will help. SELECT allows you to choose the columns you want to see within a table. If you are not sure which you would like to see … use the asterisk to see all columns within a table. SELECT * FROM u.agg_ia_clickstream Once you see the columns, you can determine which ones you want to use. SELECT c.date, c.unique_visitors PV’s FROM u.agg_ia_clickstream c FROM allows you to choose the table you want data from. SELECT c.date, c.unique_visitors PV’s FROM u.agg_ia_clickstream c WHERE allows you to filter data on a row level. The WHERE clause is applied before the GROUP BY clause. SELECT c.date, c.unique_visitors PV’s FROM u.agg_ia_clickstream c WHERE c.date > 20070801 In this case, the WHERE clause allows you to see ony unique visitors who have PV’s greater ( > ) than 10. GROUP BY - When you use aggregate functions in a SELECT statement such as sum, count, etc., place the non-aggregate functions in the GROUP BY. An aggregate function operates on table rows to calculate and return a single function. Examples of aggregate functions are: sum(), avg(), count(), max(), and min(). You can intuitively guess what the functions do. Sum() for instance will sum, whereas avg() will average, etc. SELECT c.date, sum(c.unique_visitors) PV’s FROM u.agg_ia_clickstream c WHERE c.date > 20070801 GROUP BY c.date So, whenever you use an aggregate function in a SELECT statement, make sure that the NON aggregate functions are in the GROUP BY keyword. That is what I mean by punctuation in SQL. Whenever you write a sentence, you put a period at the end of the sentence. Whenever you write a SQL query, you put your punctuation in the GROUP BY. HAVING group level filtering is commonly used to eliminate rows. It is written after the GROUP BY clause. Aggregate functions can be used in the HAVING clause. SELECT c.date, sum(c.unique_visitors) PV’s FROM u.agg_ia_clickstream c WHERE c.date > 20070801 GROUP BY c.date HAVING sum(c.unique_visitors) > 10 ORDER BY is used to order your output. The order of rows returned by a SQL query is not guaranteed unless you use a ORDER BY clause. SELECT c.date, sum(c.unique_visitors) PV’s FROM u.agg_ia_clickstream c WHERE c.date > 20070801 GROUP BY c.date HAVING sum(c.unique_visitors) > 10 ORDER BY sum(c.unique_visitors) desc In this query, I want to see my results sorted by PV’s. By following the instructions above, the learning process shouldn't be too difficult. With this training, you can now write basic Oracle SQL queries. When you do, don’t forget to follow the SQL basics order I provided: SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY. Also consider breaking up Oracle SQL statements over multiple lines to make them easier to read and debug. Have fun! Required Tools: Oracle SQL Quick Tips: Break up Oracle SQL statements over multiple lines to make them easier to read and debug. SQL statements are case-insensitive. You can use capital letters or lower case letters; it’s up to you. Hit F9 to run your query. Useful Links: Download Oracle

Relational Algebra: Select(σ), Project(∏):Union(∪) in DBMS
 
15:18
In This lecture you will learn about Relational Algebra and their different types of operations like: Select(σ), Project(∏):Union(∪):Set Difference (-) Operations, Rename operations(ρ) , Cartesian Product (X) in DBMS. What is Relational Algebra?: Every DBMS must define a query language that allows users to access the data from database.  Relational Algebra is a procedural query -language which is used to access the data from database through query. In relational algebra, INPUT is a relation(table from which data has to be accessed) and OUTPUT is also a relation(a temporary table holding the data asked by the user). Relational Algebra works on the whole table. In this, we specify the table name from which we need the data, and in a single line of command, relational algebra will traverse the entire given table to fetch the data. Operations in Relational Algebra : Following operations performed on table using relational algebra are: Select Project Union Set Different Cartesian product Rename Relational Algebra is also used for Join operations like : Natural Join Outer Join Theta join Select Operation (σ): This operation is used to fetch rows (tuples) from table(relation) which satisfies a given condition. It is denoted by σ. Syntax: σp(r) Where, σ represents the Select Predicate, r is the table (relation) name (table name in which you want to look for data), and p is the Prepositional logic where we specify the conditions that must be satisfied by the data. In prepositional logic, one can use unary and binary operators like =, etc, to specify the conditions. Example: Student table, we want to access those students having age 17 years. How we will write it in relational algebra : σage 17 (Student) This will fetch the tuples(rows) from table Student, for which age will be greater than 17. You can also use, and, or etc operators, to specify two conditions, for example, σage 17 and gender = 'Male' (Student) This will return tuples(rows) from table Student with information of male students, of age more than 17.(Consider the Student table has an attribute Gender too.) Project Operation (∏) : This operation is used to project only a certain set of attributes of a relation(Table). It is denoted by ∏. Example: If we want to see the name of the students in the Student table, then we can use Project Operation. It will only project or show the columns(attributes) asked for, and will also remove duplicate data from the columns. Syntax: ∏A1, A2...(r) where A1, A2 are attribute name(column name). For example, ∏Name, Age(Student) Above statement will show us only the Name and Age columns for all the rows of data in Student table. Union Operation (∪) : It is used to fetch the data from two relations(tables). In this, the each relations(tables) should have same number of attributes(columns) and same attribute domain. In this, the duplicate tuples are automatically removed from the result. Syntax: A ∪ B where A and B are relations. For example, if we have two tables Regular Class and Extra Class, both have a column student. How we will write : ∏Student(RegularClass) ∪ ∏Student(ExtraClass) Above operation will give us name of Students who are attending both regular classes and extra classes, eliminating repetition. Set Difference (-): This operation is used “To find data present in one relation and not present in the second relation”. This operation is also applicable on two relations, just like Union operation. Syntax: A - B where A and B are relations. For example, if we want to find name of students who attend the regular class but not the extra class, then, we can use the below operation: ∏Student(RegularClass) - ∏Student(ExtraClass) FOR MORE VIDEO SUBSCRIBE THE CHANNEL : Computer science academy by Dinesh Sir

Aggregate functions in SQL programming in Hindi Video
 
09:45
Aggregate functions in SQL Let us have idea of Aggregate functions in SQL. Aggregate functions of SQL or you can say group functions in sql are the functions that can work on group of rows. An aggregate function in SQL allows you to perform a calculation on a set of values to return a single scalar value. We will have an idea about five group functions or aggregate functions of sql. • AVG – this is an aggregate function of sql, it calculates the average of a set of values. • COUNT –this is an aggregate function of sql, it counts rows in a specified table or view. • MIN – this is an aggregate function of sql, it gets the minimum value in a set of values. • MAX –this is an aggregate function of sql, it gets the maximum value in a set of values. • SUM – this is aggregate function of sql, itcalculates the sum of values. Sum function of sql can be used to find sum of values. Suppose the query is give sum of salaries of all the employees from employee table. The answer to this query would be: select sum(salary) from employee; This will list sum of salaries of all the employees from employee table. avg function of sql To find average of the values of a column. It works on numeric columns only. Give average salary from employee table. select avg(salary) from employee; It will list average salary from the employee table. min function of sql . To find minimum value from the values of a column. It works on numeric columns only. Give minimum salary from employee table. select min(salary) from employee; It will list lowest salary from the employee table. max function of sql To find maximum value from the values of a column. It works on numeric columns only. Give highest salary from employee table. select max(salary) from employee; It will list highest salary from the employee table. count function of sql Give total number of records of employee table whose city is ynr. So this was all about aggregate functions of sql. Our facebook page http://www.facebook.com/learningsveryday Blog htttp://www.ethtimes1.blogspot.com Channel http://www.youtube.com/learningeveryday
