• Can php query the results from a previous query?

  - by eaolson

  In some languages (ColdFusion comes to mind), you can run a query on the result set from a previous query. Is it possible to do something like that in php (with MySQL as the database)? I sort of want to do: $rs1 = do_query( "SELECT * FROM animals WHERE type = 'fish'" ); $rs2 = do_query( "SELECT * FROM rs1 WHERE name = 'trout'" );

• Calculating average (AVG) and grouping by week on large data set takes too long

  - by caioiglesias

  I'm getting average prices by week on 7 million rows, it's taking around 30 seconds to get the job done. This is the simple query: SELECT AVG(price) as price, yearWEEK(FROM_UNIXTIME(timelog)) as week from pricehistory where timelog > $range and product_id = $id GROUP BY week The only week that actually gets data changed and is worth averaging every time is always the last one, so this calculation for the whole period is a waste of resources. I just wanted to know if mysql has a tool to help out on this.

• Porting from MS Access

  - by lacqui

  I've recently been given a MS Access .mdb database file and asked to make it usable in a Linux system. What I'm looking for is a way to convert the Access database to an open-source database such as MySQL or PostGres. I don't have MS Office, and it's a one-time project for a volunteer organization so I don't want to spend money if it's avoidable. I'm running Vista x64, and have a Linux virtualbox, so something usable in either one will be good.

  I have a 'price' variable that contains some integer number from a MySQL database. I want to check how many numbers the 'price' variable contains, and add a space in the variable depending on how many numbers. See below: Example: If 'price' is 150000 I would like the output to be 150 000 (notice the space). OR, if it is 19000 I would like it to output 19 000... How would you do this the easiest way?
