Execute an DELETE query.

Parameters

url
unused
keyfield	where clause field
lookup	value of field for where clause
fields	list containing one or more field/value set(s)

Delete a row from a database table, prepare the sql statement using keyfield and lookup control the number of records to change. Additional params to match rows are stored in ap list. Sub-in the values to the prepared statement and execute it.

Return values

number	of rows affected
-1	on failure

Execute an UPDATE query.

Parameters

url
unused
keyfield	where clause field
lookup	value of field for where clause
fields	list containing one or more field/value set(s).

Update a database table, prepare the sql statement using keyfield and lookup control the number of records to change. All values to be changed are stored in ap list. Sub-in the values to the prepared statement and execute it.

Return values

number	of rows affected
-1	on failure
