You can insert a single record by passing a struct:
You can specify any query param options such as the SQL type by passing a struct with the parameters you would pass to cfqueryparam
.
Raw values can be supplied to an insert statement.
Multiple rows can be inserted in a batch by passing an array of structs to insert
.
This is not the same as looping over and array and calling insert
in the loop. Using an array with insert
will batch the inserts in one SQL call. Looping over an array and calling insert
each time will create a SQL request for each item in the array. Bottom line, pass your array to insert
!
returning
is only supported in PostgresGrammar
and SqlServerGrammar
. Using this method on unsupported grammars will result in an UnsupportedOperation
exception. Be aware that using this method constrains your grammar choices.
Specifies columns to be returned from the insert query.
Updates a table with a struct of column and value pairs.
You can specify any query param options such as the SQL type by passing a struct with the parameters you would pass to cfqueryparam
.
Any constraining of the update query should be done using the appropriate WHERE statement before calling update
.
You can update a column based on another column using a raw expression.
Null values can be inserted by using queryparam syntax:
if you are using Lucee with full null support the following (easier) syntax is also allowed:
Adds values to a later update
, similar to addSelect
.
Performs an update statement if the configured query returns true
for exists
. Otherwise, performs an insert statement.
If an update statement is performed qb applies a limit( 1 )
to the update statement.
If the configured query returns 0 records, then an insert statement is performed.
Deletes all records that the query returns.
The id
argument is a convenience to delete a single record by id.

The get
method is the most common method used for retrieving results. It executes using the configured QueryBuilder
and returns the results.
get
can also take a list or array of columns to use as a shortcut. If any are passed, those columns will be used instead of any columns previously set on the QueryBuilder
.
If you just need to retrieve a single row from the database table, you may use the first
method. This method will return a single record (a Struct
by default). If no row is found an empty Struct
will be returned by default.
If you don't even need an entire row, you may extract a single value from each record using the values
method. The values
method will return the column of your choosing as a simple array.
This method is similar to values
except it only returns a single, simple value. Where values
calls get
under the hood, this method calls first
.
If no records are returned from the query, one of two things will happen. If the throwWhenNotFound
boolean is set to true
, a RecordCountException
will be thrown. Otherwise the defaultValue
provided to the method will be returned.
Large datasets can be broken up and retrieved in chunks. This allows you to work with a subset of results at once to keep your memory footprint under control.
chunk
can be called on any query like you would call get
. You can stop the retrieving and processing early by returning false
from the callback.
Generates a pagination struct along with the results of the executed query. It does this by calling both count
and forPage
.
A pagination collector is the name given to the struct returned from calling the paginate
method. It can be a struct or a component. It needs one function defined and will be passed the following parameters.
You can set your custom pagination collector either in the constructor using the paginationCollector
argument or by calling setPaginationCollector
on a query builder instance.
By default, qb ships with cbpaginator
as its pagination collector. The return format of cbpaginator
is the example shown above.
The query builder also provides a variety of aggregate methods such as count
, max
, min
, and sum
. These methods take the headache out of setting up these common aggregate functions.
When executing any of the aggregate functions, any where
restrictions on your query will still be applied.
Instead of returning a query, these methods return a simple value.
Returns true
if the query returns any rows. Returns false
otherwise.
Returns an integer number of rows returned by the query.
Returns the maximum value for the given column.
Returns the minimum value for the given column.
Returns the sum of all returned rows for the given column.
