CFQUERYPARAM
CFQUERYPARAM checks the data type of a query parameter. The CFQUERYPARAM tag
is nested within a CFQUERY tag. More specifically, it is embedded within the query
SQL statement. If you specify its optional parameters, CFQUERYPARAM also performs
data validation.
Note For data, you must specify the MAXLENGTH attribute in order to ensure
that maximum length validation is enforced.
See the Usage section for details.
