TSQLQuery.UpdateSQL property
Statement to be used when updating an existing row in the database.
Declaration
property UpdateSQL:;Description
UpdateSQL can be used to specify an SQL
UPDATE
statement, which is used when an existing record was modified in the dataset,
and the changes must be written to the database.
TSQLQuery can generate
an update statement by itself for many cases, but in case it fails, the
statement to be used for the update 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
