It has some data and more objects. How do I find out how much memory the stud object

I placed the files on Head Fist's site on apache's /var/www folder and the thing runs. Yet, why isn't php's mailto working? edit: btw, I'm working on Ubuntu 10.04 I added two debugging lines to the script: $testmail = mail($to, $subject, $msg); echo 'WAS IT MAILED? <br />'.$testmail; Why isn't printing WAS IT MAILED? TRUE ? Why isn't it mailing? Edit: Is the fact that I'm mailing to my gmail address relevant? Here's the script: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0

I cannot get the Spring Validation codes to automatically map to my externalized messages.properties. It will only work if I add my own LocalValidatorFactoryBean and use the fully qualified javax constraint message. Goal I want to override the defaultMessage for @javax.validation.constraints.NotNull globally in my application based on Spring Validation code s.

Handcrafted Strongly Typed ADO.net DataTable - Can it be cleaner?

I've tried to push the repetitive methods into a super class, but I have issues due to the Employee needing to be generic. I was hoping to get StackOverflow's collective hive mind to suggest some ideas to clean this up?

MySQL LEFT JOIN - Values can be NULL

由 匿名 (未验证) 提交于 2019-12-03 02:29:01
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I'm modifying a MySQL statement but having a few troubles with LEFT JOIN and blank rows. At the moment I have: SELECT cs.case_id, cs.child_firstname, gu.* FROM tblcases AS cs LEFT JOIN tblguardians AS gu ON cs.case_id = gu.case_id WHERE cs.child_firstname = '%craig%' AND gu.firstname LIKE '%sally%' This query works fine as long as there is an entry in the "tblguardians" table, but the LEFT JOIN returns NULL if there is no record - therefore the entry isn't returned when I iterate over the results in PHP. Is there a way to return the fields
