15.5.4.Using Input Parameters
Parameters declarations should be described in the
<header> section of the updategram. There should be one
<param>
row for each
parameter.
General syntax:
<sql:header xmlns:sql="xml-sql"> <sql:param name="PARAM_NAME" [default="DEFAULT_VALUE"]/> ... </sql:header>
Where PARAM_NAME
is the
name of the parameter and DEFAULT_VALUE
is optional default of
parameter Parameters in updategram should have $PARAM_NAME
instead of a value. On
processing, Virtuoso replaces $PARAM_NAME
with the corresponding
value from the <input_parameters>
given to the
function xmlsql_update()
.
