• Changing GORM table name

  - by Matthias Hryniszak

  Hi I'm fighting to get the following mapping working in Grails 1.3.1 and MySQL: class Login { int id String email static mappings = { table 'my_table' id column: "Mgr_id" version: false } } No matter what I do the queries that are being issued refer to "schema.login" table instead of "schema.my_table".

• [PHP] Read and write to a file while keeping lock

  - by Znarkus

  Hi! I am making a simple page load counter by storing the current count in a file. This is how I want to do this: Lock the file Read the current count Increment it Write new count Unlock file/close it Can this be done? As I understand it, the file can't be written to without losing the lock. The only way I have come up with to tackle this, is to write a character using "r+" mode, and then counting characters.

• Does the java JFC hash table use seperate chaining resolution? Can I traverse each list in the table

  - by Matt

  I have written a program to store a bunch of strings in a JFC hash table. There are defiantly collisions going on, but I don't really know how it is handling them. My ultimate goal is to print the number of occurrences of each string in the table, and traversing the bucket or list would work nicely. Or maybe counting the collisions? Or do you have another idea of how I could get a count of the elements?

• Does table columns increase select statement execution time

  - by paokg4

  I have 2 tables, same structure, same rows, same data but the first has more columns (fields). For example: I select the same 3 fields from both of them (SELECT a,b,c FROM mytable1 and then SELECT a,b,c FROM mytable2) I've tried to run those queries on 100,000 records (for each table) but at the end I got the same execution time (0.0006 sec) Do you know if the number of the columns (and in the end the size of the one table is bigger than the other) has to do something with the query execution time?
