For some reason I keep getting 0 as last insert id. Here is my code; databaseobjects.php public static function create () { global $db; $attributes

mysql getting last_insert_id() in a trigger

阅读更多关于 mysql getting last_insert_id() in a trigger

It's my understanding that when you call last_insert_id() it goes by connections, so you'll get the id of the last row inserted on the same connection where last_insert_id() is called, right? So what if I call last_insert_id() in an 'AFTER INSERT' trigger? What I want to do is basically this DELIMITER $$ CREATE TRIGGER sometrigger AFTER INSERT ON sometable BEGIN INSERT INTO anothertable (id, lastup) VALUES (last_insert_id(), NOW()); END $$ It's very important that the id in 'anothertable' is the same as in 'sometable' Would this work or should I create a stored procedure instead that inserts

问题 I am using Postgresql, when I want to use PDO to retrieve the latest insertion ID, I got a problem. Here is my code: $db->lastInsertId('columnName'); The error message says SQLSTATE[42P01]: Undefined table: 7 ERROR: relation "columnName" does not exist I guess I have some misunderstanding about "sequence object" stated in the PHP Manual.

阅读更多关于 What happens when auto_increment on integer column reaches the max_value in databases?

问题 I am implementing a database application and I will use both JavaDB and MySQL as database. I have an ID column in my tables that has integer as type and I use the databases auto_increment-function for the value. But what happens when I get more than 2 (or 4) billion posts and integer is not enough? Is the integer overflowed and continues or is an exception thrown that I can handle?

How to program a MySQL trigger to insert row into another table?

阅读更多关于 How to program a MySQL trigger to insert row into another table?

I'm looking to create a MySQL trigger on a table. Essentially, I'm creating an activity stream and need to log actions by users. When a user makes a comment, I want a database trigger on that table to fire and: Grab the ID of the last inserted row (the id of the comment row). perform an INSERT into an activities table, using data from the last inserted row. I'll essentially replicate this trigger for deleting comments. Questions I had: Is LAST_INSERT_ID() the best way to grab the id? How do I properly store the data from the last inserted comment row for use in my "INSERT into activities"
