I have a question about using the propel ORM and creating a query.
I have a table “locations” with fields:
Now I want to select all the locations where the location field IS NOT equal to ‘null’.
How can I do this? I’ve tried this but I get back all the results …
$locations = LocationQuery::create()->where('location' != null)->find();
I don’t know propel. But the proper SQL syntax for the expression would be:
$locations = LocationQuery::create()->where('location is not null')->find();
Any comparison to
NULL in SQL returns
NULL, which is treated as false. With the exception of
is null and
is not null.
You can use this:
There are various ‘Criteria’ uses in propel, listed here: propel criteria
There isn’t an exact sample for this on the site, the closest is this:
->filterByTags(array('novel', 'russian'), Criteria::CONTAINS_NONE)
You can also use
You can reference all of the Propel 2 comparison types for
EQUAL NOT_EQUAL ALT_NOT_EQUAL GREATER_THAN LESS_THAN GREATER_EQUAL LESS_EQUAL LIKE NOT_LIKE CONTAINS_ALL CONTAINS_SOME CONTAINS_NONE ILIKE NOT_ILIKE CUSTOM RAW CUSTOM_EQUAL DISTINCT IN NOT_IN ALL JOIN BINARY_AND BINARY_OR ASC DESC ISNULL ISNOTNULL CURRENT_DATE CURRENT_TIME CURRENT_TIMESTAMP LEFT_JOIN RIGHT_JOIN INNER_JOIN LOGICAL_OR LOGICAL_AND
