The filter expects an object of the related class as parameter: Propel also generates a filterByXXX() method for every foreign key. That means that the resulting query often requires an expensive table scan, and is not suited for large tables.

filterByTags ( array ( 'novel', 'russian' ), Criteria :: CONTAINS_ALL ) -> find () // example Query generated for a MySQL database $query = 'SELECT book.* from `book` WHERE book.TAGS LIKE :p1 AND book.TAGS LIKE :p2' // :p1 => '%| novel |%', :p2 => '%| russian |%' $books = BookQuery :: create () -> filterByTags ( array ( 'novel', 'russian' ), Criteria :: CONTAINS_NONE ) -> find () // example Query generated for a MySQL database $query = 'SELECT book.* from `book` WHERE book.TAGS NOT LIKE :p1 AND book.TAGS NOT LIKE :p2 OR book.TAGS IS NULL' // :p1 => '%| novel |%', :p2 => '%| russian |%' // If the column name is plural, Propel also generates singular filter methods // expecting a scalar parameter instead of an array $books = BookQuery :: create () -> filterByTag ( 'russian' ) -> find () // example Query generated for a MySQL database $query = 'SELECT book.* from `book` WHERE book.TAGS LIKE :p1' // :p1 => '%| russian |%'įilters on array columns translate to SQL as LIKE conditions.

The previous example generates the following code when find() is called: When a termination method like find() is called, Propel builds the SQL code and executes it.

Remember to always use the phpName in the PHP code the actual SQL name only appears in the SQL code. The column name used in the PHP method is not the actual column name in the database (' published_at'), but rather a CamelCase version of it (' PublishedAt'), called the column ''phpName''. Propel generates one filterByXXX() method for every column in the table. find(), on the other hand, is a ''termination method'' that doesn't return the query, but its result - in this case, a collection of Book objects. Propel queries are made of method calls that return the current query object - filterByPublishedAt() and orderByTitle() return the current query augmented with conditions. The first thing to notice here is the fluid interface. Here’s an example to demonstrate.FilterByPublishedAt ( array ( 'min' => time () - 30 * 24 * 60 * 60 )) -> orderByTitle () -> find () If the value is not a JSON document, or if it cannot cannot be parsed as one, the function fails with an error. This must be a JSON value or a valid string representation of a JSON value. Where json_val is the JSON value to format. The syntax goes like this: JSON_PRETTY(json_val) The function then returns those values formatted according to its formatting rules. You provide the JSON values as an argument to the function. It returns the JSON values in a nicely formatted way, which makes it easier for us humans to read. In MySQL, the JSON_PRETTY() function provides pretty-printing of JSON values.
