updateAll()

Description

Updates all properties for the records that match the where argument. Property names and values can be passed in either using named arguments or as a struct to the properties argument. By default objects will not be instantiated and therefore callbacks and validations are not invoked. You can change this behavior by passing in instantiate=true. This method returns the number of records that were updated.

Function Syntax

updateAll([ where, include, properties, parameterize, instantiate ])

Parameters

Parameter Type Required Default Description
where string No This argument maps to the WHERE clause of the query. The following operators are supported: =, <>, <, <=, >, >=, LIKE, AND, and OR (note that the key words have to be written in upper case). You can also use parentheses to group statements. You do not have to specify the table name(s), Wheels 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.
properties struct No [runtime expression] The properties you want to set on the object (can also be passed in as named arguments).
parameterize any No true Accepts a boolean value or a string. Set to true to use cfqueryparam on all columns or pass in a list of property names to use cfqueryparam on those only.
instantiate boolean No false Whether or not to instantiate the object(s) first. When objects are not instantiated any callbacks and validations set on them will be skipped.

Examples

<!--- Update the `published` and `publishedAt` properties for all records that have `published=0` --->
<cfset recordsUpdated = model("post").updateAll(published=1, publishedAt=Now(), where="published=0")>

<!--- If you have a `hasMany` association setup from `post` to `comment` you can do a scoped call (the `removeAllComments` method below will call `model("comment").updateAll(postid="", where="postId=#post.id#")` internally) --->
<cfset aPost = model("post").findByKey(params.postId)>
<cfset removedSuccessfully = aPost.removeAllComments()>
