The INSERT INTO statement in SQLite is used to add new rows of data to a specified table. This command can insert a single row at a time or multiple rows using a single INSERT statement. It is a fundamental part of the SQL Data Manipulation Language (DML), allowing for the creation and...
sqlite> INSERT INTO Cars(Id) VALUES(4); The INSERT statement omits the last 2 columns. Such columns are filled with the default value or NULL if there is no default value. The Name column does not have a default value, so there is a NULL value. In the CREATE TABLE statement, we ...

是的,在SQLite中,你可以在INSERT语句上触发UPDATE触发器。触发器是一种特殊的数据库对象,它可以在执行特定的数据库操作(如INSERT、UPDATE、DELETE等)时自动执行相应的操作。 在SQLite中,你可以使用CREATE TRIGGER语句来创建一个触发器。例如,以下语句将在INSERT操作发生时触发名为my_trigger的触发器: 代码语言:txt ...
