Oracle REPLACE Function
 
03:55
https://www.databasestar.com/oracle-replace/ The Oracle REPLACE function is a string manipulation function that allows you to replace one text string with another. It can be a whole word or sentence, or even a single value. The syntax of the REPLACE function is: REPLACE ( whole_string, string_to_replace, [replacement_string]) To use this function, the parameters are: - whole_string (mandatory): This is the string that will be checked for the characters to be replaced. - string_to_replace (mandatory): This is the string that will be searched for within whole_string. - replacement_string (optional): This is the string that will be used to replace occurrences of string_to_replace. Because the last parameter is optional, if it is not specified, then the Oracle REPLACE function removes all occurrences of string_to_replace. You can replace carriage returns with REPLACE, but you’ll need to use the CHR function. You can replace NULL values in Oracle, but this is best done with another function such as NVL, rather than REPLACE. If you want to replace multiple characters, you can do this using nested REPLACE functions or a REGEXP_REPLACE function. For more information about the Oracle REPLACE function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-replace/

In this regular expressions (regex) tutorial, we're going to be learning how to match patterns of text. Regular expressions are extremely useful for matching common patterns of text such as email addresses, phone numbers, URLs, etc. Almost every programming language has a regular expression library, so learning regular expressions with not only help you with finding patterns in your text editors, but also you'll be able to use these programming libraries to search for patterns programmatically as well.

09 MySQL Tutorial for Beginners: LIKE + REGEXP Operators, Regular Expressions
 
09:12
You use the LIKE operator to retrieve rows that match a string pattern. The Mask for a LIKE phrase can contain special symbols called "wildcards". Masks aren't case-sensitive. In contrast to the LIKE operator, the REGEXP operator allows you to create complex string patterns known as regular expressions. The mask for a REGEXP phrase can contain special characters and constructs like: - the "caret" (^) symbol matches the pattern to the beginning of the value being tested. - The "dollar sign" ($) symbol matches the pattern to the end of the value being tested. - The "pipe" (|) symbol separates two string patterns and matches either one. - "Square brackets" [] are used to specify multiple values. lf you use the NOT keyword, only those rows with values that don't match the string pattern are included in the result set.

Part 2 SQL functions- character function -case manipulation functions Previous Video Link :: http://youtu.be/5rx8Q4x4-qI Tool used in this tutorial is command prompt. This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials. This SQL Tutorial is a part of free training.

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.

Tool used in this tutorial is command prompt. This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials.

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

LNNVL FUNCTION IN ORACLE SQL
 
09:11
This video is the 5th video in the series of 'working with null', this video explains the working of the lnnvl function in oracle sql with simple and easy to understand example. LNNVL provides a concise way to evaluate a condition when one or both operands of the condition may be null. The function can be used only in the WHERE clause of a query. It takes as an argument a condition and returns TRUE if the condition is FALSE or UNKNOWN and FALSE if the condition is TRUE. LNNVL can be used anywhere a scalar expression can appear, even in contexts where the IS [NOT] NULL, AND, or OR conditions are not valid but would otherwise be required to account for potential nulls. Oracle Database sometimes uses the LNNVL function internally in this way to rewrite NOT IN conditions as NOT EXISTS conditions. In such cases, output from EXPLAIN PLAN shows this operation in the plan table output. The condition can evaluate any scalar values but cannot be a compound condition containing AND, OR, or BETWEEN.

In this video tutorial, we discuss the pseudo column rowid and rownum in oracle sql. After watching this video you would be able to understand the basic difference between rowid and a rownum pseudo columns of oracle database. Rowid returns the exact location of the row in the database, hence whenever you retrive a record based on rowid, it is the fastest retrival possible. Whereas for each row returned by a query, the ROWNUM pseudocolumn returns a number indicating the order in which Oracle selects the row from a table or set of joined rows.
