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.

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.

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.

SELECT "Hello World" FROM DUAL The first thing you should know about writing queries is that this SQL is not whitespace sensitive. That means we can space this out however we wish. The only requirement is that you do not separate keywords out with spaces. They must be as one entity. Another gotcha is that when you are inside of quotes, whitespace becomes very important. That means if inside of a string you put a character and then 10 spaces, every single one of those spaces is going to part of that string: SELECT "Hello World" FROM DUAL The next thing you should notice is the capitalization. When we type SQL, by convention we capitalize all keywords. I personally really like this because you can easily see the difference between keywords and words that we created or use. But obviously we could capitalize the letters in the quotes. Keep in mind that this is a convention, meaning you do not have to follow this. Oracle is also case insensitive in that SELECT and select both do the same thing. Strings, once again, care about casing. Take this, for example: SELECT 'true' FROM DUALWHERE 'Hello' = 'Hello' And compare the results to this: SELECT 'true' FROM DUALWHERE 'Hello' = 'hello' Only the first one outputs the value true. Once we get into creating database objects such as tables with columns, those are not case sensitive either. That means instead of selecting from DUAL, you can select from DuAl Finally, I shall introduce you to comments. Comments allow you to tell the database engine that you want it to ignore a certain part of your code and not execute it. This is helpful if you want to document your code. It is also useful if you want to have multiple SQL statements open in one tab, but don't want to hover over the one you want to execute. You can comment out the ones you are not using and uncomment them when you are done. Using – will comment out the rest of the line, Using /* */ will comment everything between. This can even be used over multiple lines.

link of SQL substr blog : http://www.rebellionrider.com/SQL-substr-function.htm SQL substr function SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. 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.

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

The Oracle DECOMPOSE function is used to transform a string into a Unicode string. It will split a character that has an accent, for example, into two characters. It’s the opposite of the COMPOSE function. The syntax of the DECOMPOSE function is: DECOMPOSE ( input_string [CANONICAL|COMPATIBILITY] ) The parameters of this function are: - input_string is the string that will be decomposed into separate character values in a string. It can be any character data type. - CANONICAL|COMPATIBILITY is an optional parameter and allows you to specify the mode of decomposition. CANONICAL is the default. CANONICAL means it can be re-composed with the COMPOSE function. COMPATIBILITY means that it can’t be re-composed, but it can be useful for katakana characters.

https://www.databasestar.com/oracle-trim/ The Oracle RTRIM function allows you to remove a specific character from the right side of a string. It’s one of the most commonly used string manipulation functions in SQL, in my experience. The “R” in “RTRIM” stands for “right”. It’s often used to remove spaces from the right of a string. However it can be used to remove other characters, such as trailing slashes from URLs. The syntax for the RTRIM function is: RTRIM(input_string, [trim_character]) The input_string is the text you want to remove characters from. It can be any kind of expression, such as a specific text value or a column. The trim_character is the character you want to remove from the right of the string. It’s an optional parameter, and if you don’t specify it, then a space character is used by the function. The parameters can be any type of string. The function will return either a VARCHAR2 or a LOB data type, depending on the type of data you specify in the parameters. You can specify more than one value for the trim_character, and the RTRIM function will remove both characters from the right of the string. The function is similar to the LTRIM value, where LTRIM removes characters from the left of the string. For more information on the RTRIM function, including the SQL used in this video, read the related article here: https://www.databasestar.com/oracle-trim/

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.

https://www.databasestar.com/oracle-instr/ The Oracle INSTR function allows you to search a string for the occurrence of another string, and return the position of the occurrence within a string. It’s helpful for finding if a string exists within another string. It can also be used for performing further string manipulation on, like substrings. The syntax of the INSTR function is: INSTR(string, substring [, start_position [, occurrence]]) These parameters are: string: The text string that is searched in. It’s usually the larger of the two strings. Mandatory. substring: The text to search for. It’s usually the smaller of the two strings. Mandatory. start_position: This is an integer value which indicates where in the string value to start the search. Optional, and the default is 1. occurrence: The occurrence of the substring to search for. Optional, and the default is 1, which means the first occurrence. Also, the searches performed by the INSTR function are case-sensitive. The value returned by INSTR is a number value, which is the number in the location of the string where the substring is found. The first character is 1.

Acesse o desafio: http://novidades.aprendaplsql.com/15-dias-de-funcoes-oracle A função Oracle substr traz o pedaço da string de uma determinada variável. Ela pode receber até 3 parâmetros, onde o primeiro é a string a ser analisada, o segundo é a posição inicial que pode ser negativo se você for contar da direta para a esquerda(ou seja de traz para frente) e também como parâmetro opcional um terceiro inteiro que vai trazer o tamanho do caracter. SELECT substr('O Aprendaplsql é o melhor site', 3) FROM dual; SELECT substr('O Aprendaplsql é o melhor site', 3, 12) FROM dual; SELECT substr('O Aprendaplsql é o melhor site', -11, 6) FROM dual; https://www.youtube.com/playlist?list=PLMaqczuL07LkjrX6Rvx6TdNM-1nbUKG8p

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.
