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()
.
