SQL COMMENTS - The Coding Shala

Home >> Learn SQL >> SQL Comments

SQL COMMENTS

SQL Comments are added for the purpose of making the source code more readable for the programmers. Comments are not executed, they are just for explanation. In SQL, there is two type of comments - Single line comments and multi-line comments.
SQL COMMENTS - The Coding Shala

Single-Line Comments

Single line comments start with '--' so any text between -- and the end of the line will not be executed. The following example uses a single line comment - 

 -- this is single line comment  
 select * from emp --this is also single line comment;

Multi-Line Comments

Multi-line comments start with '/*' and end with '*/' so any text between /* and */ will be skipped. The following example uses multi-line comments -  

/* this is multiple line comment  
 this is also in multi-line comment   
 end of multi-line comment */  
 select * from emp --this is single line comment;

New Year Chaos Solution - The Coding Shala

Home >> Programming Questions >> New Year Chaos New Year Chaos Problem Solution In this post, you will learn how to solve New Year Chaos Problem and implement its solution in Java. Problem:   It's New Year's Day and everyone's in line for the Wonderland rollercoaster ride! There are a number of people queued up, and each person wears a sticker indicating their initial position in the queue. Initial positions increment from at the front of the line to at the back.  Any person in the queue can bribe the person directly in front of them to swap positions. If two people swap positions, they still wear the same sticker denoting their original places in line. One person can bribe at most two others.  For Example, if n=8 and Person 5 bribes Person 4, the queue will look like this: 1,2,3,5,4,6,7,8. Fascinated by this chaotic queue, you decide you must know the minimum number of bribes that took place to get the queue into its current state. Input:

Goal Parser Interpretation LeetCode Solution - The Coding Shala

Home >> LeetCode >> Goal Parser Interpretation  In this post, we will learn how to solve LeetCode's Goal Parser Interpretation Problem and will implement its solution in Java. Goal Parser Interpretation Problem You own a Goal Parser that can interpret a string command. The command consists of an alphabet of "G", "()", and/or "(al)" in some order. The Goal Parser will interpret "G" as the string "G", "()" as the string "o", and "(al)" as the string "al". The interpreted strings are then concatenated in the original order. Given the string command, return the Goal Parser's interpretation of the command. Example 1: Input: command = "G()(al)" Output: "Goal" Explanation: The Goal Parser interprets the command as follows: G -> G () -> o (al) -> al The final concatenated result is "Goal". Example 2: Input: command = "G()()()()(al)&qu
