Using SQL with ColdFusion 37

Writing SQL and CFML statements to interact with a data source

After ColdFusion makes a connection to the data source, you can interact with that database by

using SQL and ColdFusion.

To interact with an established data source, you must include SQL statements in your CFML

statements; for example:

SELECT FirstName, LastName, DepartmentID

From Employee

</cfquery>

In this example, the first attribute of the cfquery tag is the name of the query. The second

attribute of the

cfquery tag defines the name of the data source. The SELECT statement defines

the fields (columns) to be retrieved from a table named Employee.

CFML tags that interact with a database

The following table lists the CFML tags that you can use to interact with a database:

Part II of this manual introduces these tags when you use them to interact with the sample

database. For more information about interacting with a database, see ColdFusion MX Developer’s

Guide or CFML Reference.
