MYSQL FORMATTER CODE

When these systems read the code file, they even have to read these elements. These elements are the extra elements in the computer systems' eyes, browsers, and search engines. The elements like line breaks, comments, commas, and spaces that the programmer adds to format the code, take space and make your code file size large.

FORMAT function in MySQL is used to formats the number as a format of '. Even though you are an experienced programmer, if you do not properly format the code, your job will be at risk. Also, in the future, you can understand the hierarchy of code. The code delivers the intent of what the programmer wants to offer. The resulted code will be shown in the 'Result' section. To beautify and format your minified SQL code. It includes the line breaks, comments, commas, and spaces to format the code in an organized manner. You can either copy-paste the SQL code, load it from the URL, or use the 'browse' option to upload the file. Therefore, the programmer does the coding in a way that the human eye can read it. Even the small, tiny mistake makes your code disfunction. One way is to do the code for humans, and the second is to do it for computers and browsers search engines because humans and systems view the code differently. When the programmer writes a code, it can be done in two ways. What are beautification and formating in code means, and why is it important?

That's it, hope this article helps you in understanding comments in SQL and how to use them.Before going deeper into the SQL code beautification and formation. The keyboard shortcut to uncomment query or text is CTRL + K, CTRL + U.Ĭommenting text or query in PostgresSQL is same as SQL Server, you can start with '/*' enter text or query and then end it with '*/'. The keyboard shortcut to comment query or text in SQL Server is CTRL + K, CTRL + C. We have given example of it above here is another example /* multi line comment SQL Comment block is considered when you write comment within a Transact-SQL statement using multiple-line comments which must be indicated by /* and */.Ī stylistic convention often used for multiple-line comments is to begin the first line with /*, subsequent lines with **, and end with */. Or you can also have inline comments as SELECT * FROM /* Customers this is comment */ SQL comment block Where MiddleName = 'E' - these are conditionsĪnd the above examples works perfectly for me in SQL Server. You can use inline comments using '-' after the query or even using '/* */' whichever works for you, I have taken example of using two dashes '-' comment after query SELECT * FROM. Multi line comments, can be used as inline comments also and syntax remains same for SQL Server, MySQL and Oracle database, it starts with '/*' and follow the comment with an asterisk and forward slash basically ends with '*/'. Single line comment Syntax is same in MySQL, SQL Server and Oracle database, but in MySQL, you need to keep a space after double dashes, like this '- this is comment -' Multi Line Comments

Single line comment in SQL can be done using '-Some text-', basically you need to begin your line with two dashes '–' -Single line comment.

Single line comments: Single query lines is commented.

Multiline-comments: Multiple query lines are commented in this type.

Inline-comments : Comments inside query.

So, comments are used in code to understand the piece of code more clearly to explain the sections of the SQL statements, and it can be also be used to prevent the statements of SQL to execute. In previous article, I have mentioned SQL Server Management Studio (SSMS) Versions but now in this article, I have provided examples to comment query in SQL, which can be useful for you as a database developer to provide comments in query, so other developer can understand why specific query was written and how it is used or why query was used.
