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.

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.

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. For more information about the Oracle INSTR function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-instr/

This screencast shows the new gstyle search mode in nvPY 0.9.3 onwards. Regular expression searching is still available, either via configuration setting, or by toggling the option menu to the right of the search bar. gstyle is 3 to 4 times faster. This should be noticeable on collections of a few hundred notes and more. For most use cases, you should be able to find the note that you want more easily. For the other cases, you can switch to regexp. case insensitivity (the CS checkbox set to off) is significantly slower for both gstyle and regexp. At the end of the screencast, I mistakenly said 0.9.2 instead of 0.9.3.

Replace function in sql server : Replaces all occurrences of a specified string value with another string value. Returns a string with all the instances of a substring replaced by another substring. Example : SELECT REPLACE('? 1 is an example of REPLACE()','?', 'Video') ; Syntax REPLACE ( string_expression , string_pattern , string_replacement ) string_expression Specifies the string that contains the substring to replace all instances of with another. string_pattern Specifies the substring to locate. string_replacement Specifies the substring with which to replace the located substring. The REPLACE function performs a replacement that is not case-sensitive. So all occurrences of string_to_replace will be replaced with replacement_string regardless of the case of string_to_replace or replacement_string.

Welcome to our Tech Talk Tricks channel.in this video, we will learn about the like operator as well as their attributes. so this video is helpful for finding out the matching pattern in the database. So watch: https://www.youtube.com/watch?v=XjGI2gp6b9g #TechTalkTricks #RanaSingh The SQL LIKE clause is used to compare a value to similar values using wildcard operators. There are two wildcards used in conjunction with the LIKE operator. So this video is: SQL | Like Operator | Part-15 | Hindi/English The percent sign (%) The underscore (_) The percent sign represents zero, one or multiple characters. The underscore represents a single number or character. These symbols can be used in combinations. Basic structure of % and _ is as follows − SELECT FROM table_name WHERE column LIKE 'XXXX%' or SELECT FROM table_name WHERE column LIKE '%XXXX%' or SELECT FROM table_name WHERE column LIKE 'XXXX_' or SELECT FROM table_name WHERE column LIKE '_XXXX' or SELECT FROM table_name WHERE column LIKE '_XXXX_' You can combine N number of conditions using AND or OR operators. Here, XXXX could be any numeric or string value. sql like wildcard sql like multiple values sql like pattern sql like regex sql like escape sql like case insensitive sql like multiple words like query in mysql 1.How to make your computer start up & shut down faster https://www.youtube.com/watch?v=3kSjizTn7MM 2.How To Trace Name/Address/Location Of UnKnown Number Easily https://www.youtube.com/watch?v=kyYfOP66l1Y 3.How to make web page print friendly https://www.youtube.com/watch?v=YPR7JHA0Apk 4.How to Lock Folder Without any software https://www.youtube.com/watch?v=BhEduEM9pws 5.How to enable undo in Gmail https://www.youtube.com/watch?v=g1fOwTQ3zJg 6.How To Recover All Deleted, Formatted, Damaged Files https://www.youtube.com/watch?v=fl3DX6RBoqo 7.How to make Bootable USB pen drive for Windows https://www.youtube.com/watch?v=IXJE859pxWg 8.How to Unlock Android Pattern or Pin Lock without losing data https://www.youtube.com/watch?v=yN4JnAo7SvU 9.how to track a cell phone location for free https://www.youtube.com/watch?v=0kCLyPJ8cM0 10.How to fix or repair pen drive using cmd https://www.youtube.com/watch?v=ny4VhM2TsWM 11.how to get wifi password of neighbour https://www.youtube.com/watch?v=LCFn6IjvnMM 12.How to Send an Email In Future https://www.youtube.com/watch?v=oo84GRHe5Vg 13.How To Setup Wifi Hotspot Without Any Software in Windows 10 https://www.youtube.com/watch?v=6Bzyvs44G50 14.how to download YouTube video without any software https://www.youtube.com/watch?v=RDfDGY3Be9Y 15.HOW TO SET SHUTDOWN TIMER IN WINDOWS OS (HINDI) https://www.youtube.com/watch?v=Vb5Ou7sc4uk 16.How To convert Word File (Any File Format) to PDF file (Any File Format) https://www.youtube.com/watch?v=Nd0YtV9MwqQ 17.How To Hide Drive of Computer Using Command Prompt (Hindi) https://www.youtube.com/watch?v=AddrPKRGdSk

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.
