Wildcards can be used in MySQL to perform a fuzzy search, with the most common wildcards being % and _.

  1. Match any number of characters, which can appear at any position in the string.
  2. Match a single character, which can appear at any position in the string.

For example, if you want to search for all records that begin with A, you can use the following SQL statement:

SELECT * FROM table_name WHERE column_name LIKE 'A%';

To search for all records ending with A, you can use the following SQL statement:

SELECT * FROM table_name WHERE column_name LIKE '%A';

To search for all records containing A, you can use the following SQL statement:

SELECT * FROM table_name WHERE column_name LIKE '%A%';

To find all records that start with A and have a length of 3, you can use the following SQL statement:

SELECT * FROM table_name WHERE column_name LIKE 'A__';

By using wildcards, you can conduct fuzzy searches more flexibly and locate records that meet the criteria.
