Dear Developers, I would like to suggest the inclusion of an extension in PostgreSQL. There are instances, I found, when one needs to INSERT several times the same record in a table. The front-end application can do it easy in a loop of a sort, but on remote servers (and that's the norm these days) it creates unnecessary network traffic.
My suggestion is to allow INSERT to do it REPEAT x. This should allow, in my view, the followings: a) INSERT INTO my_table (field1, field2, field3) VALUES (value1, value2, value3) REPEAT 5; should insert 5 identical rows b) INSERT INTO my_table (field1, field2, field3) VALUES (x, value2/x, value3) REPEAT (x=3); should insert the followings: 1, value2, value3 2, value2/2, value3 3, value2/3, value3 In other words, this form of INSERT shold instruct the SQL engine to perform a for loop. Maybe instead of REPEAT there should be another word, maybe the for loop should allow going with a different step than the default one and go backward as well (easy to do with a negative step). This suggestion comes for a practical project that I have. I haven't feel the need for something like that in an UPDATE, but I can imagine that it may happen: UPDATE my_table SET field1=value1*x WHERE condition REPEAT (x=(SELECT repetition FROM table2 WHERE condition2) STEP -1.5); Best regards, Sorin Schwimmer ____________________________________________________________________________________ Expecting?
