php - How to Set a Value to NULL when using Zend_Db -

-

While updating using Zend_Db and displaying the INSERT query, I often set the value equal to NULL (not '') Need to do However, the default behavior of Zend_Db :: insert () and Zend_Db :: update () seems that the empty values ​​are translated into empty strings ('') and put into the database.

Itemprop = "text">

Try setting the affected areas to: New Zend_Db_Expr ('NULL')

sql server - SQL Query - Delete duplicates if more than 3 dups? -

-
Is there an elegant SQL statement for deleting duplicate records in a table, but only if X is the number of duplicates? So it allows up to 2 or 3 duplicates, but what is it? At present I have a statement that does the following: Remove table from table, left outer (duplicate from table group like Triad, Diplo 1, Duplex 2) 1, Select Max (ID) by Dupl 2. Maintenance as TDI) = Maintenance. Where are kept. Road is empty This works very well. But what I want to do now will only remove those lines, if they have more than 2 duplicates. Thanks with in the form of CT (select row_member ( )) (Divol1 by split, dupol2 sequence by id) from table as rn) from cte where rn & gt; 2; - or & gt; 3 etc. The query is being classified by a 'line number' for each record, (Dupl 1, Dupl 2) and ordered by ID.

I should be able to tell who is the operator and who is the administrator, though, and it is possible that I probably want to be able to do this through PAM. / P> So my idea is that I have two services with two different configurations , /etc/pam.d/pamdemo and Administrator /etc/pam.d/pamdemo-admin My application will then try to authenticate before pamdemo-admin , and if it is unsuccessful then pamdemo . If both fail, then admission is denied. Am I on the right track or am I complete...
