Adding data using the simpler, cfinsert approach
For those who would prefer not to have to remember SQL syntax to add information to SQL
databases, ColdFusion simplifies the coding for inserting SQL rows through the use of the
tag. As you might expect, the

to specify where the data is inserted. The tag also has a

cfinsert
<cfinsert datasource="CompassTravel" tablename="Trips"
formfields="tripName, eventType, tripDescription, tripLocation, departureDate,
returnDate, price, tripLeader, photo, baseCost, numberPeople,

The tag used in the previous code snippet uses the following attributes:

Attribute Description
datasource The data source name associated with the database where the data is inserted.
tablename The name of the SQL table within the database where the data are inserted.
formfields A comma-separated list of form fields to insert.
Exercise: insert trip data using cfinsert
In this exercise, you change the approach the action page uses to insert the data into the database.
You will replace the SQL INSERT statement with the

The SQL INSERT statement identifies that the data are to be

The values refer to form variables passed from the data entry
