# Wildcards in SQL
SQL does not use Regex. Instead it has a simpler glob-like syntax for carrying out string matching.
In order to signal that you wish to compare by a wildcard and not a value, you have to use the `LIKE` keyword. The actual wildcard operator is `%` .
In an SQL statement, the `%` wild card will match any number of occurrences of any character.
Any characters can appear before or after MacBook and the record will still be returned:
```sql
SELECT name, cores, release_date
FROM model
WHERE name LIKE '%MacBook%';
```
This wildcard only filters characters that come after `Raspberry` :
```sql
SELECT name, cores, release_date
FROM model
WHERE name LIKE 'Raspberry%';
```
