The purpose is that I want to create a table, and then ask for username, if the username isn't in the table, (check for empty fetch() statement), then add to table. It will tell you how many records are in the table, whether or not they are different (although you will more than likely have at least one unique column, in which case they must all be different). Bear in mind that there is a very slim chance that the number of records changes between you fetching the count and fetching the data itself.
I have a query to calculate objects that are within a certain radius of a point based on a document here: It works very nicely however I want to only search for those objects that are of a particular type, and this is causing a problem; The code looks like this: my $sql = "SELECT * FROM ( SELECT b.*, pr.postcode, pr.prize, pr.title, pr.collection, pr.redeemed, pr.delivery, pr.archived, bt.category, p.radius, p.distance_unit * DEGREES(ACOS(COS(RADIANS(p.latpoint)) * COS(RADIANS(b.lat)) * COS(RADIANS(p.longpoint - b.lng)) SIN(RADIANS(p.latpoint)) * SIN(RADIANS(b.lat)))) AS distance FROM bubbles AS b, bubble_prizes AS pr, bubble_types AS bt JOIN ( /* these are the query parameters */ SELECT ? I'm now thinking that escaping isn't my problem and I'm missing something about execute.
You don't need to actually send it any statements, but then you do know that the quoting format will be correct for the database you will use.
varies from database to database, and it doesn't make sense to call it in a database-independent way.
In short form, it's an alternative to the traditional newspaper pyramid structure (in which, if you lopped off the bottom part of the story, the reader would still have all the key information).
