How can I use this trick: How to get ID of the last updated row in MySQL? in Go (golang)?
I am using the go-sql-driver. It should work with these two queries but how can I do it in Go?
INSERT INTO table (unique_id) VALUES ("test")
ON DUPLICATE KEY UPDATE id=LAST_INSERT_ID(id);
SELECT LAST_INSERT_ID();

MySQL LAST_INSERT_ID() Function The LAST_INSERT_ID() function returns the AUTO_INCREMENT id of the last row that has been inserted or updated in a table.
How to get last inserted id of a MySQL table using LAST_INSERT_ID() We will be using the LAST_INSERT_ID() function to get the last inserted id. Last_insert_id() MySQL function returns the BIG UNSIGNED value for an insert statement on an auto_increment column.
To get an ID of last inserted record, you can use this T-SQL: INSERT INTO Persons (FirstName) VALUES ('Joe'); SELECT ID AS LastID FROM Persons WHERE ID = @@Identity; You can use query like this inside stored procedure or as an ad-hoc query.
Working solution. It is as simple as that. I hope someone else will find this useful:
stmt, err := db.Prepare("INSERT table SET unique_id=? ON DUPLICATE KEY UPDATE id=LAST_INSERT_ID(id)")
res, err := stmt.Exec(unique_id)
lid, err := res.LastInsertId()
