TSQLQuery.UpdateSQL

Statement to be used when updating an existing row in the database

Declaration

Source position: sqldb.pp line 669

published property TSQLQuery.UpdateSQL : TStringList;

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
