04 MySQL Tutorial for Beginners: USE, SELECT, result set, DISTINCT, ALL
 
12:35
In this video you will begin to code your first "SQL statements" in MySQL Workbench. The very first thing you need to do is to choose and select a database. The "USE statement" is the one you’re going to need for this purpose, and it's the very first statement you're going to learn. The second statement you're going to learn is the "SELECT statement" which is used to retrieve data from a base table. You code the SELECT keyword followed by a list of column names separated by commas and the FROM keyword followed by the name of the base table from which the query retrieves the data. A "result set" is a table of data resulted from a statement: you can think of it as a temporary table that's created within a database. Note that when you execute a USE statement alone, you do not get any results back, because a USE statement itself does not expect to have any results back. In the SELECT clause, you can code an asterisk as a shorthand to indicate that all of the rows and columns should be retrieved. By default, all of the rows in the base table are included in the result set. In some cases, that means that the result set will contain duplicate rows, or rows whose column values are identical. If that's not what you want, you can include the DISTINCT keyword in the SELECT clause to eliminate the duplicate rows. The DISTINCT keyword prevents duplicate rows from being included in the result set. The ALL keyword causes all rows matching the search condition to be included in the result set, regardless of whether rows are duplicated. The ALL keyword is the default and can therefore be omitted.

Using DISTINCT in SQL
 
08:53
A brief beginner's introduction to the DISTINCT operator in SQL. DISTINCT creates a set of unique records, based on field values. In other words, duplicates records, based on field values, are removed. DISTINCT is often used with COUNT, to achieve a count of distinct values. Be aware that NULL is treated as a distinct value in terms of records, but COUNT ignores NULLs. See the full code here: https://douglaskline.blogspot.com/2018/10/using-distinct-in-sql.html

SQL SELECT statement is used to fetch the data from a database table which returns data in the form of result table. These result tables are called result-sets. The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. In SQL, wildcard characters are used with the SQL LIKE operator. SQL wildcards are used to search for data within a table. With SQL, the wildcards are: Wildcard Description % A substitute for zero or more characters _ A substitute for a single character [charlist] Sets and ranges of characters to match [^charlist] or [!charlist] Matches only a character NOT specified within the brackets Check out our website: http://www.telusko.com Follow Telusko on Twitter: https://twitter.com/navinreddy20 Follow on Facebook: Telusko : https://www.facebook.com/teluskolearnings Navin Reddy : https://www.facebook.com/navintelusko Follow Navin Reddy on Instagram: https://www.instagram.com/navinreddy20 Subscribe to our other channel: Navin Reddy : https://www.youtube.com/channel/UCxmkk8bMSOF-UBF43z-pdGQ?sub_confirmation=1 Telusko Hindi : https://www.youtube.com/channel/UCitzw4ROeTVGRRLnCPws-cw?sub_confirmation=1

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.

How will you eliminate duplicate values from a query result in MySQL?
 
02:45
Q. How will you eliminate duplicate values from a query result in MySQL? MySQL provides DISTINCT keyword to remove duplicates from a query result. With DISTINCT keyword, a value will be displayed only once. Eg. SELECT DISTINCT NAME FROM EMPLOYEE; This query will return each name in Employee table only once. Q. How will you get the size of data in a MySQL table? In MySQL, there is an information_schema that contains the TABLES object. We can run a query on TABLES to get the size of data in a table. Eg. If we have a table named EMPLOYEE, the query to get the size of data will be as follows: SELECT table_name "Table Name",sum( data_length + index_length ) / 1024 / 1024 "Table Size (MB)" FROM information_schema.TABLES WHERE table_name='EMPLOYEE'; Learn more MySQL interview questions, join our popular MySQL Interview Questions Preparation Course with more than 50 questions for $10 only today!! https://www.udemy.com/mysql-interview-questions-preparation-course/?couponCode=KPOWER10 Source: http://www.knowledgepowerhouse.com/video-course

Oracle COUNT Function
 
04:43
https://www.databasestar.com/oracle-count/ The Oracle COUNT function is used to count the number of rows from the column, or number of values, provided to it. It’s commonly used to find the number of rows returned by a SELECT query. The syntax of the COUNT function is: COUNT ( [ * | [ DISTINCT | ALL ] expression) [ over (analytic_clause) ] There’s a lot of square brackets here, indicating optional parameters and choices. This just means you can use the COUNT function in a few different ways: COUNT(*) COUNT(DISTINCT expression) COUNT(ALL expression) COUNT(*) OVER (analytic_clause) COUNT(DISTINCT expression) OVER (analytic_clause) COUNT(ALL expression) OVER (analytic_clause) It can be used as an aggregate or analytic function. The parameters of the COUNT function are: - expression: The expression to count the values of. This can be a column or a set of values, for example. - analytic_clause: This is used to specify the criteria for an analytic query. COUNT(*) is the most common way to use this function, I’ve found. As COUNT(*) is an aggregate function, like all aggregate functions the columns mentioned in the SELECT clause need to exist in the GROUP BY clause. NULL values are ignored by COUNT(expression), but they are counted when using COUNT(*). COUNT(*) has the exact same calculation and performance as COUNT(1). For more information about the Oracle COUNT function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-count/
