TSQLQuery.DeleteSQL property
Statement to be used when deleting a new row in the database.
Declaration
property DeleteSQL:;Description
DeleteSQL can be used to specify an SQL
DELETE
statement, which is used when an existing record was deleted from the dataset,
and the changes must be written to the database.
TSQLQuery
can generate a delete statement by itself for many cases, but in case
it fails, the statement to be used for the delete operation can be specified here.
The SQL statement should be parameterized according to the conventions
for specifying parameters. Note that old field values can be specified
as :OLD_FIELDNAME
