In MySQL, regular expressions can be used for data querying and matching, with the options of using either LIKE or REGEXP.

  1. Use the LIKE operator for fuzzy matching, but keep in mind that it only supports wildcard matching and not regular expressions. An example is shown below:
SELECT * FROM table_name WHERE column_name LIKE 'pattern';
  1. Perform regular expression matching using the REGEXP operator, as shown below:
SELECT * FROM table_name WHERE column_name REGEXP 'pattern';

‘pattern’ is a regular expression pattern that can be customized to match different requirements.

For example, to query data in column_name that starts with ‘abc’, you can use the following query statement:

SELECT * FROM table_name WHERE column_name REGEXP '^abc';

You can refer to the official MySQL documentation for more regular expression rules and syntax.
