I likely know just enough about SQL Queries to be dangerous... I have a query that I simply do not trust and would like some help with it. This is against multiple tables (6) using various JOINS and some WHERE booleans. I'd like someone to look at the query and see if I am doing it correctly for my goals. The query is provided for someone who thinks they can help me. I can provide more details about my goals once someone is awarded the project.

Hello, I think the query might look a bit more scary than it is, in part because there's a lot of text. If you take away the backticks (the backwards-looking quotation marks) and ton-plus- (conceptually, not actually), it would look much smaller and maybe more approachable. There's data from 6 tables. The criteria to join and filter take up a few lines but each criterion is pretty clear. I don't see any real complexity, this query doesn't seem so bad at all. My usual rate is USD 112 per hour, which probably explains why I do so few projects here, but your rate range seems incredibly generous. Which is great, of course, but I wonder if you've found a specific problem or there's something unclear about the goals you mentioned, which makes creating the sql to get to those goals unclear. Getting some more details about the goals would be handy but I wonder if the other way around might be easier - I, or anyone else, could explain what the sql does first and then it mght be become clearer to you if the sql you have so far is on the right track, if anything's been missed, etc. Cheers.

Hi! We have a lot of experience in MySql and databases in general (10 year experience in teach databases at university included). Your query is complicated but in my opinion it will work on depending of data and tables definitions (are present foreign keys included in joins or not, for example). We hope to work with you. Please, contact us by Freelancer chat. Have a nice day!
