我想创建一个用户'projectA',它对每个名为'projectA_%'的数据库具有相同的权限

我知道它可能,但MySQL不喜欢我的语法:

grant all on 'projectA\_%'.* to 'projectA'@'%';

参考:http://dev.mysql.com/doc/refman/5.1/en/grant.html

通常,在使用SELECT查询数据库时,通常需要查找与给定搜索字符串匹配的记录.

例如:

SELECT * FROM customers WHERE name LIKE '%Bob Smith%';

该查询应该给我所有记录,其中'Bob Smith'出现在名称字段的任何位置.

我想做的是相反的.

我没有找到名称字段中包含"Bob Smith"的所有记录,而是希望找到名称字段位于"Robert Bob Smith III,PhD."中的所有记录,这是查询的字符串参数.

对重复参考的评论:为什么在被引用为重复的问题之前多年被问到时,这会被标记为重复？我也相信问题,细节和反应要比引用的问题好得多.

我已经做了很长一段时间的C++程序员,但我是Java的新手,也是Eclipse的新手.我想使用触摸图形"图形布局"代码来可视化我正在使用的一些数据.

此代码的组织方式如下:

如何在Eclipse中添加此项目并使其快速编译和运行？

我可以做这个:

$ find .
.
./b
./b/foo
./c
./c/foo

还有这个:

$ find . -type f -exec cat {} \;
This is in b.
This is in c.

但不是这个:

$ find . -type f -exec cat > out.txt {} \;

为什么不？

我正在尝试决定放在一个对话框中的内容,该对话框告诉用户他们的登录不起作用,可能有重复.系统使用电子邮件地址作为用户名,然后需要密码.

现在,我正在使用"电子邮件登录",但这听起来很愚蠢.

例如:

1)应用程序启动,识别它从未运行过.2)提示用户创建新帐户.3)用户输入电子邮件地址和密码作为新凭据.4)好吧,看起来他们已经有了一个账号.(这是最有可能的情况,帐户创建失败,但我使用的是API,我不能100%这就是它失败的原因)5)我要求他们再试一次不同的"电子邮件登录".

Could not create account - try a different email login !

在我与API提供商核实后,我可能会尝试检测到它实际上是一个重复的帐户,并要求他们尝试使用密码验证该帐户.

我有一个表格,其中包含如下记录:

CREATE TABLE sample (
  ix int unsigned auto_increment primary key,
  start_active datetime,
  last_active datetime
);

我需要知道过去30天每天有多少记录活跃.日期也应该按递增顺序进行排序,以便将它们最旧的返回到最新.

我正在使用MySQL,查询将从PHP运行,但我不需要PHP代码,只需要查询.

这是我的开始:

SELECT COUNT(1) cnt, DATE(?each of last 30 days?) adate
FROM sample
WHERE adate BETWEEN start_active AND last_active
GROUP BY adate;

由于多个开发人员在同一个Tomcat应用程序上工作,我想告诉应用程序根据当前用户和版本控制客户端/视图安装到不同的路径.

因此,如果Bob正在构建,那么应该将应用程序安装在Bob的测试环境中,可能是/ bob1或类似的东西.Bob可能有多个与他合作的版本控制客户端/视图/工作区,因此他可以拥有/ bob1,/ bob2,/ bob3等.

安装位置在build.properties文件中指定.有没有办法避免检查该文件并为每个特定用户和版本控制视图更改它？

"ant install"可以接受参数还是配置为考虑安装目标的环境变量？
