sql:insert and sql:column
sql:insert performs an SQL INSERT statement. This causes a row to be added to the table identified
table attribute. The
table attribute holds the table name as a constant string; it is not
possible to set the name of the table (or of the columns) at run-time.
There is a mandatory
connection attribute, used as in the
instruction described above.
sql:column is used as a child element of
sql:insert, and identifies the name and value of a column
to be included in the INSERT statement. The name of the column is identified by the
the value may be indicated either by evaluating the expression contained in the
select attribute, or
as the expanded contents of the
sql:column element. The value is always interpreted as a string.
(Remember this is purely a demonstration of extensibility, in a real system there would be a need to
cater for SQL columns of other data types).
