C Examples of Assignment Statement
assignment-source
specifies a list of value expressions, a list of rowset expressions, the NULL
specification, or a subquery. These values are to be inserted into the
assignment-target.
subquery
| {expression | rowset-expression | NULL}
[,{expression | rowset-expression | NULL}]...
is a value expression, rowset expressions, NULL, or the result of a subquery.
NULL can be assigned to a host variable of any type.
If you use a rowset expression or if the subquery returns more than one row,
the assignment target must consist of rowset host variables.

VALUES (:hv_ordernum, :hv_orderdate, :hv_delivdate,
:hv_salesrep, :hv_custnum);
