Deleting records using the 'LIMIT' clause
Hi all, I have positively identified the row I want to delete using: 'SELECT * FROM table LIMIT 10,1' This has returned 1 record and I now want to DELETE the record. How do I identify this record in my DELETE statement? (using 'DELETE FROM table LIMIT 10,1' does not work) NOTE : I can't identify it using it's key fields as the table has no primary key. Help greatly appreciated. Regards ... Ross . Ross Honniball JCU Bookshop Cairns Supervisor . James Cook Uni, McGreggor Rd, Smithfield, Qld. 4878, Australia .

How do I determine the row number or key when table has no key fields
eg. say a table is created using: create table fred (f1 char(10), f2 int) Then it has neither keys nor an AUTO_INCREMENT field. Let's say 1000,000 records are then inserted into table fred. I then say 'select * from fred' and loop through results writing to a web page. I stop writing to the web page after say 20 records. The user hits 'next page'. I want to say 'select * from fred where ?field? ?value? Where ?field? and ?value? are what I want to know. Surely there is some kind of 'record number' or something available in mySQL for me to : 1. Retrieve and save 2. Query against I'm new to this mailing list. Apologies if I am asking this question of an inappropriate email address. Regards ... Ross .
