Operation Manual

5. Click Test to connect to the database and create an instance of the recordset.
If the SQL statement contains variables, make sure the Default Value column of the Variables box contains valid test values
before clicking Test.
If successful, a table appears displaying the data in your recordset. Each row contains a record and each column represents a
field in that record. Click OK to clear the recordset.
6. If satisfied with your work, click OK.
Options for the advanced Recordset dialog box (ColdFusion)
Use the advanced Recordset dialog box to write custom SQL queries, or use the Database Items tree to author SQL queries using a point-and-
click interface.
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 characters or
spaces.
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: The 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.
2. Select a data source from the Data Source pop-up menu.
If no data source appears in the pop-up menu list, you will need to first create a ColdFusion data source.
3. 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 and
password to access a data source in ColdFusion, contact your organization’s ColdFusion administrator.
4. Enter a SQL statement in the SQL text area or use the graphical Database Items tree at the bottom of the dialog box to build
a SQL statement from the chosen recordset.
5. (Optional) Do the following to use the Database Items tree to build the SQL statement:
Ensure the SQL text area is blank.
Expand the branches of the tree until you find the database object you need—for example, a column in a table.
Select the database object and click one of the buttons on the right side of the tree.
For example, if you select a table column, the available buttons are Select, Where, and Order By. Click one of the buttons to
add the associated clause to your SQL statement.
If your SQL statement contains parameters, define their values in the Parameters area by clicking the Plus (+) button and
entering the parameter’s name and default value (the value the parameter should take if no run-time value is returned).
If the SQL statement contains parameters, make sure the Default Value column of the Parameters box contains valid test
values.
The Page Parameters allow you to provide default values for run-time value references in the SQL you write. For example, the
following SQL statement selects an employee record based on the value of the employee’s ID. You can assign a default value
to this parameter, ensuring that a run-time value is always returned. In this example, FormFieldName refers to a form field in
which the user enters an employee ID:
SELECT * FROM Employees WHERE EmpID = + (Request.Form(#FormFieldName#))
The Add Page Parameters dialog box would contain a name-value pairing similar to:
Name Default values
FormFieldName
0001
The run-time value is usually a URL or form parameter entered by a user in an HTML form field.
