Re: Natural Join Issue: column names are equal but doesn't work anyways

Hi again, since I'm not someone who gives up easily, I have restyled that old code (actually is from an example back of my teacher into 2002, I saw that she changed a bit her way to code this stuff), I restyled the code just to be sure it isn't some parsing issue or whatever. http://pastebin.com/f5

Natural Join Issue: column names are equal but doesn't work anyways

Hello, I have been training for a test on Database Design and MySQL. The following is inside a file we have to run before starting to code what the excercises require us to. Call the file as you wish and run it if it helps to understand the reason behind my problem. --- DROP

Thanks, adding the indexes worked beautifully. I'll go knock my head on the desk now. Thanks for your time :) Ed Edward Ritter said the following on 7/20/2004 1:08 PM: Thanks, I'll take a look at that. The id isn't unique, so that's why I added the idx column. Does my query look okay beyond tha

Thanks, I'll take a look at that. The id isn't unique, so that's why I added the idx column. Does my query look okay beyond that? I'll add the additional indexes and try again. Ed Garth Webb said the following on 7/20/2004 1:03 PM: What is the 'idx' for when you already have an 'id' column? Al

Re: newbie join issue

What is the 'idx' for when you already have an 'id' column? Also, you need an index on the column that you are joining on; having a single indexed column on a table doesn't automatically improve all queries against that table. Put an index on the 'email_address' fields of both tables. You'll ne

Re: newbie join issue

I would expect that the speed problems are due to missing indices. Did you do proper indexing? If unsure, post your table structures and query. Stefan Am Tuesday 20 July 2004 17:45 schrieb Edward Ritter: > I've got a task that's gonna require me to compare one table to another > and remove the ro

I've got a task that's gonna require me to compare one table to another and remove the rows from the first table that are found in the second table that match email_address. I'm running 4.0.20a-nt-log. The first table has 10 colomns and about 50K records, and the second table has 46 columns and

Hi - I'm running 4.0.18, so I can't use subqueries. I need to run a query to get the sum of costs from multiple tables for a given master table. What I have right now which is clearly not going to work is: SELECT conveyor.serial, SUM(conveyorsupport.cost), SUM(conveyoraccessories.cost) from (

If you want to restrict the tuples you get from 'broadcasts' use AND instead of WHERE. Cheers /rudy -Original Message- From: gerald_clark [mailto:[EMAIL PROTECTED] Sent: dinsdag 7 oktober 2003 15:42 To: Wayne Helman Cc: [EMAIL PROTECTED] Subject: Re: Multiple Join Issue Lea

Multiple Join Issue

How would one join multiple table and selected all records from a joined table whether they exist OR not? I can get the records if they exist in a second table and I can get the records if they don't exist, but is there a way to combine the two? I have, for example, a statement like this (selects
