15.2.7.3 INSERT DELAYED Statement

INSERT DELAYED ...

The DELAYED option for theINSERT statement is a MySQL extension to standard SQL. In previous versions of MySQL, it can be used for certain kinds of tables (such asMyISAM), such that when a client usesINSERT DELAYED, it gets an okay from the server at once, and the row is queued to be inserted when the table is not in use by any other thread.

DELAYED inserts and replaces were deprecated in MySQL 5.6. In MySQL 8.0,DELAYED is not supported. The server recognizes but ignores the DELAYED keyword, handles the insert as a nondelayed insert, and generates anER_WARN_LEGACY_SYNTAX_CONVERTED warning: INSERT DELAYED is no longer supported. The statement was converted to INSERT. TheDELAYED keyword is scheduled for removal in a future release.
