sql - Using SubString when not knowing position or length -


Can someone help me as I need to remove the number after "code =" reference = "? It is not possible to know the number of characters before or after the number as well as the number of length (can also be letters and numbers), but it is always

"Reference =" first ", description"

object = CTSENORaanG, reference = 0000021357, description = test, currency = EUR, Initial_Date = 15Aug2011 ....

The string is from a table with a large amount of rows and I must include the reference of each row in another table

SQL Server 

  declare @str varchar (1000) set @ Str = 'object = ctsnorang, reference = 0000021357, description = test, currency = EUR, Initial_Date = 15Aug2011 ....'; Select from substring (col, 1, charindex (',', col) -1) (select substring (@ str, charindex ('references =', @ str) +10,100);;   
 MySQL  
  set @str: = 'object = ctsnorang, reference = 0000021357, description = test, currency = EUR, Initial_Date = 15Aug2011 ....'; Substring (Col, 1) Select (from ',', cola) -1) (substring (@ str, find out ('reference =', @ str) +10,100);;

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...
