Like
Next: SQL ORDER BY
LIKE is another keyword that is used in the WHERE clause. Basically, LIKE allows you to do a search based on a pattern rather than specifying exactly what is desired (as in IN) or spell out a range (as in BETWEEN). The syntax is as follows:
SELECT "column_name"
FROM "table_name"
WHERE "column_name" LIKE {PATTERN}
{PATTERN} often consists of wildcards. We saw several examples of wildcard matching in the previous section. Below we use an example to see how wildcard is used in conjunction with LIKE:
Table Store_Information
store_name | Sales | Date |
LOS ANGELES | $1500 | Jan-05-1999 |
SAN DIEGO | $250 | Jan-07-1999 |
SAN FRANCISCO | $300 | Jan-08-1999 |
BOSTON | $700 | Jan-08-1999 |
We want to find all stores whose name contains 'AN'. To do so, we key in,
SELECT *
FROM Store_Information
WHERE store_name LIKE '%AN%'
Result:
store_name | Sales | Date |
LOS ANGELES | $1500 | Jan-05-1999 |
SAN DIEGO | $250 | Jan-07-1999 |
SAN FRANCISCO | $300 | Jan-08-1999 |
