In order to help with documentation of MS-SQL databases, I wrote this small ColdFusion utility to produce the table schemas from a given database. It is very simple and easy to install. I just recommend you to use it only on your development server or localhost, without external access, otherwise you will be supplying information to hackers.

It is composed of one ColdFusion template (CFM) and a component (CFC).

There is only one required URL attribute to be passed and 3 optional ones:

• datasource (required): datasource (registered in CF admin)
• table (optional): table name
• fList (optional): list of columns you want to show
• fLabels (optional): labels for the columns

If you omit the table attribute, the utility will list all tables in the database.

You may download the code here.

Here is the CFM that calls the component, you may call it dbSchema.cfm:
<cfparam name="url.datasource" default="" />
<cfparam name="url.table" default="" />
<cfscript>
if (len(trim(url.datasource))) {
cf = createObject("component", "ws.dbSchema");
result = cf.getSchema(url.datasource, url.table);
if (result.status) {
result = cf.showSchema(result.content);
} else writeOutput(result.content);
} else writeOutput("Missing DATASOURCE attribute!");
</cfscript>
Here is the component, you may call it dbSchema.cfc:
<cfcomponent displayname="dbSchema" hint="Display table schemas" output="true">
