sql - duplicate rows in table, but need to change data in one column -


मेरे पास तालिका step_year है: id, step_id, वर्ष

I उन सभी पंक्तियों का डुप्लिकेट बनाना है जो वर्ष = 1011 (चरण = वर्ष से * चुनें * वर्ष = 1011), लेकिन उसी वर्ष (1011) होने वाली उन नव निर्मित पंक्तियों के बजाय मैं इसे 1112 में बदलना चाहता हूं।

किसी भी मदद की सराहना की जाती है।

आप INSERT कोड> सेलेक्ट लेकिन इसे क्वेरी से खींचने के बजाय वर्ष निर्दिष्ट करें 

  `step_year` (` आईडी`, `कदम_आईडी`,` वर्ष`) में शामिल करें चयन 'आईडी' , `Step_id`, 1112 के रूप में` वर्ष` से `चरण_ययार` जहां` वर्ष` = 1011   
 यह वाक्य-रचना MySQL के लिए है, लेकिन अधिकांश डेटाबेस के लिए अनुकूलनीय होना चाहिए।  < / div>

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
