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:
SELECT name, cores, release_date
FROM model
WHERE name LIKE '%MacBook%';
This wildcard only filters characters that come after Raspberry :
SELECT name, cores, release_date
FROM model
WHERE name LIKE 'Raspberry%';
