sql:insert performs an SQL INSERT statement. This causes a row to be added to the table identified
by the 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 sql:query
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 name attribute,
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).
