MySQL's AUTO_INCREMENT behavior in a multiple row insert

问题 I think the answer to my question is obvious but since I could not find any documentation to support it, I thought it's worth asking. At least for the record. As we all know AUTO_INCREMENT fields are incremented each time an INSERT statement is executed. And its value can be retrieved by LAST_INSERT_ID() function. It is also mentioned in MySQL's Manual that with multiple-row inserts, LAST_INSERT_ID() will return the first ID of the inserted rows. Which I think is a good idea (really useful).

This is the query i have used for insert multiple rows in oracle database. But when am using sequence within it it raises error as ORA-00001: unique constraint. How to do it. INSERT ALL INTO POSTAL_CODE( postal_code,desc) VALUES(postal_code.NEXTVAL,'Coimbatore') INTO POSTAL_CODE (postal_code,desc) VALUES(postal_code.NEXTVAL,'Mumbai') SELECT * FROM DUAL; The restrictions on multitable inserts include: You cannot specify a sequence in any part of a multitable insert statement. A multitable insert is considered a single SQL statement. Therefore, the first reference to NEXTVAL generates the next

MySQL - how many rows can I insert in one single INSERT statement?

Does it depend on the number of values sets? Does it depend on the number of bytes in the INSERT statement? You can insert infinitely large number of records using INSERT ... SELECT pattern, provided you have those records, or part of, in other tables. But if you are hard-coding the values using INSERT ... VALUES pattern, then there is a limit on how large/long your statement is: max_allowed_packet which limits the length of SQL statements sent by the client to the database server, and it affects any types of queries and not only for INSERT statement. Ideally, Mysql allow infinite number of
