count()

Returns the number of rows that match the arguments (or all rows if no arguments are passed in). Uses the SQL function COUNT. If no records can be found to perform the calculation on, 0 is returned.

Name Type Required Default Description
where string No Maps to the WHERE clause of the query (or HAVING when necessary). The following operators are supported: =, !=, <>, <, <=, >, >=, LIKE, NOT LIKE, IN, NOT IN, IS NULL, IS NOT NULL, AND, and OR (note that the key words need to be written in upper case). You can also use parentheses to group statements. You do not need to specify the table name(s); CFWheels will do that for you.
include string No Associations that should be included in the query using INNER or LEFT OUTER joins (which join type that is used depends on how the association has been set up in your model). If all included associations are set on the current model, you can specify them in a list (e.g. department,addresses,emails). You can build more complex include strings by using parentheses when the association is set on an included model, like album(artist(genre)), for example. These complex include strings only work when returnAs is set to query though.
parameterize any No true Set to true to use cfqueryparam on all columns, or pass in a list of property names to use cfqueryparam on those only.
includeSoftDeletes boolean No false Set to true to include soft-deleted records in the queries that this method runs.
group string No Maps to the GROUP BY clause of the query. You do not need to specify the table name(s); CFWheels will do that for you. 
// Count how many authors there are in the table
authorCount = model("author").count();

// Count how many authors that have a last name starting with an "A"
authorOnACount = model("author").count(where="lastName LIKE 'A%'");

// Count how many authors that have written books starting with an "A"
authorWithBooksOnACount = model("author").count(include="books", where="booktitle LIKE 'A%'");

// Count the number of comments on a specific post (a `hasMany` association from `post` to `comment` is required)
// The `commentCount` method will call `model("comment").count(where="postId=#post.id#")` internally
aPost = model("post").findByKey(params.postId);
amount = aPost.commentCount();
