ColdFusion 10: Added the clientInfo attribute.

ColdFusion MX: Deprecated the connectString, dbName, dbServer, dbtype, provider, and providerDSN attributes. They do not work, and might cause an error, in releases later than ColdFusion 5.

<cfupdate datasource="cfdocexamples" tablename="EMPLOYEES">
</cfif>

<cfquery name="empTable" datasource="cfdocexamples">
SELECT * FROM EMPLOYEES
</cfquery>

<!--- This code shows the contents of the employee table and allows you to choose a row for updating. --->
<table border="1">
<cfoutput query="empTable">
<tr>
