问题 I am using PHP and MySQL. Goal: Insert a new row into a table with an auto-increment id column. While inserting this new row, I would like to copy the new inserted row's auto-increment id # into another column in the same row/entry.

问题 I have PostgreSQL 9 database that uses auto-incrementing integers as primary keys.

However, I also want to get the mapping from old to new IDs. Is there a better way to do it then just querying for the rows to copy first and then inserting new rows one at a time? Essentially I

问题 Consider this table: CREATE TABLE t (i int, j int, ...); I want to insert data into a table from a set of SELECT statements. The simplified version of my query is: INSERT INTO t VALUES ((SELECT 1), (SELECT 2), ...); The real query can be much more complex, and the individual subqueries independent.
