Options for the simple Recordset dialog box (ColdFusion)

Define a recordset for ColdFusion document types as a source of dynamic content without you having to hand code

SQL statements.

1 In the Name box, enter a name for the recordset.

A common practice is to add the prefix rs to

recordset names to distinguish them from other object names in your

code. For example: rsPressReleases

Recordset names can only contain letters, numbers, and the underscore character (_). You cannot use special

cha

racters or spaces.

2 If you’re defining a recordset for a ColdFusion component (that is, if a CFC file is currently open in Dreamweaver),

select an existing CFC function from the Function pop-up menu, or click the New Function button to create a new

function.

Note: T

he Function pop-up menu is only available if a CFC file is the current document and you have access to a

computer running ColdFusion MX 7 or better.

The recordset is defined in the function.

3 Select a data source from the Data Source pop-up menu.

If no data source appears in the pop-up menu, you must create a ColdFusion data source.

4 In the Username and Password boxes, enter the user name and password for the ColdFusion application server if

required.

Data sources in ColdFusion may require a user name and password to access them. If you do not have the user name

nd password to access a data source in ColdFusion, contact your organization’s ColdFusion administrator.

5 In the Table pop-up menu, select the database table that will provide data to the recordset.

The Table pop-up menu displays all tables in the specified database.

6 To include a subset of the table’s columns in the recordset, click Selected and choose the desired columns by

Control-clicking (Windows) or Command-clicking (Macintosh) them in the list.

7 To further limit the records returned from the table, complete the Filter section:

• From the first pop-up menu, select a column in the database table to compare against a test value you define.

• From the second pop-up menu, select a conditional expression to compare the selected value in each record

against the test value.

• From the third pop-up menu, select Entered Value.

• In the box, enter the test value.

If the specified value in a record meets your filtering condition, the record is included in the recordset.

8 (Optional) To sort the records, select a column to sort by, and then specify whether the records should be sorted in

ascending (1, 2, 3... or A, B, C...) or descending order.

9 Click Test to connect to the database and create an instance of the data source.

A table appears displaying the returned data. Each row contains a record and each column represents a field in that

cord. Click OK to close the test recordset.

10 Click OK. The newly defined ColdFusion recordset appears in the Bindings panel.
