What is like and not like in MySQL?
The LIKE and NOT LIKE expressions allow you to specify a set of similar values to be either returned or excluded from a query's results. LIKE can take two wildcards, % and _ which indicate either all characters or a single character.The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. There are two wildcards often used in conjunction with the LIKE operator: The percent sign % represents zero, one, or multiple characters.The NOT LIKE operator in SQL is used on a column which is of the varchar type. Usually, it's used with % , which is used to represent any string value, including the null character \0 . The string we pass on to this operator is not case-sensitive.

What is the opposite of like in SQL : SQL NOT LIKE behaves as you might expect, essentially returning the opposite of what the LIKE operator would. Let's substitute LIKE with NOT LIKE in one of our earlier examples and see the effect. As you can see, using NOT LIKE negates the pattern you specify. This is similar to other NOT operators you see in SQL.

What is not like value in MySQL

NOT LIKE operator in MySQL is used for pattern matching. It compares the column by the given value and returns the result that does not match the value in the NOT LIKE clause. If the statement finds the match, it will return 0. Otherwise, it will return 1.

What is the like function in MySQL : The MySQL LIKE Operator

The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. There are two wildcards often used in conjunction with the LIKE operator: The percent sign (%) represents zero, one, or multiple characters. The underscore sign (_) represents one, single character.

The LIKE operator is used in a WHERE clause to search for a specified pattern in a column.

As mentioned before, the MySQL LIKE operator is used to look for specific patterns within a string in a table. In its most basic form, it will look somewhat like this: SELECT column_name(s) FROM table_name WHERE column_name LIKE pattern; SELECT selects the columns to retrieve from the table.

What is not like in MySQL

MySQL NOT LIKE is used to exclude those rows which are matching the criterion followed by LIKE operator. Pattern matching using SQL simple regular expression comparison. Returns 1 (TRUE) or 0 (FALSE).The MySQL NOT LIKE operator works in the opposite way to the LIKE comparison operator. Instead of retrieving data according to the specified pattern, it finds everything that does not match it. This operator can be useful when we want to exclude specific data from the search results.The MySQL LIKE Operator

The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. There are two wildcards often used in conjunction with the LIKE operator: The percent sign (%) represents zero, one, or multiple characters.

In MySQL, there are several comparison operators, including:

  1. Equal to (=): Returns true if the values on both sides are equal.
  2. Not equal to (<> or !=
  3. Greater than (>): Returns true if the value on the left side is greater than the value on the right side.

How to specify not equal in MySQL : The 'not equal' operator in MySQL is represented by <> or != . It's used in a WHERE clause to filter records where the specified column's value is not equal to a given value.

What is not like a list in MySQL : NOT LIKE operator in MySQL is used for pattern matching. It compares the column by the given value and returns the result that does not match the value in the NOT LIKE clause. If the statement finds the match, it will return 0. Otherwise, it will return 1.

What is the difference between like and Regexp in MySQL

A regular expression pattern match succeeds if the pattern matches anywhere in the value being tested. (This differs from a LIKE pattern match, which succeeds only if the pattern matches the entire value.)

This feature is advantageous when we want to find records that need to be edited or reported on a spreadsheet. NOT LIKE operator in MySQL is used for pattern matching. It compares the column by the given value and returns the result that does not match the value in the NOT LIKE clause.Per the SQL standard, LIKE performs matching on a per-character basis, thus it can produce results different from the = comparison operator. LIKE operator uses WILDCARDS (i.e. %, _) to match the pattern. This is very useful to check whether a particular character or string is present in the records.

Why do we use like in MySQL : As mentioned before, the MySQL LIKE operator is used to look for specific patterns within a string in a table. In its most basic form, it will look somewhat like this: SELECT column_name(s) FROM table_name WHERE column_name LIKE pattern; SELECT selects the columns to retrieve from the table.
