values (1, <value_found>, 'London').
is this possible?
I'm querying a big mysql database with only read privileges, and I'd like to set some slow query results to a variable, 'foo', so I can use them again in other queries.
I get, ERROR 1193 (HY000): Unknown system variable '$foo'
when I enter:
set $foo := (select *
from table1 join table2
where bar = 0
group by id);
Is there a way to do this with variables, since I don't have privileges to create temporary tables?
I'm been trying to write a table trigger the queries another table that is outside the schema where the trigger will reside. Is this possible? It seems like I have no problem querying tables in my schema but I get:
Error: ORA-00942: table or view does not exist
when trying trying to query tables outside my schema. The documentation seems to elude to this notion, but it's not 100% clear to me.

I have a problem with Hibernate Native Query. I have one SELECT that selects array slice (PostgreSQL database).
The problem is that hibernate recognizes the following part: ":300" from "SELECT my_array[1:300]..." as named parameter and I get the following exception: Not all named parameters have been set.
I tried to escape the colon (:) with '\:' , '::' but with no success.
The Hibernate version is 3.2

I'm creating a service that has read-only access to the database. I have a query cache and a second level cache enabled (READ_ONLY mode) in Hibernate to speed up the service, as the tables being accessed change rarely.
My question is, if someone goes into the DB and changes the tables manually (i.e. outside of Hibernate), does the cache recognize automatically that it needs to be cleared? Is there a time limit on the cache?

I have a simple query that works:
$("#test fieldset input").each(function() { })
However, I want to select "input" and "select" elements without having to write 2 "each" queries. Is this possible?
thanks.
I have a 1 : M relationship.
I built a dynamic query based on input from users to return the listing of parents entities along with their children (using predicate builder:
(done successfully new TDataContext().Ps.Where(predicate) )...
but need to order the results by a field found only on the child entities.
I'm at a loss: new TDataContext().Ps.Where(predicate).OrderBy(p = p.Cs. ??)
where Ps = parents collection relationship with Cs = child entities
any help appreciated.
Hi,
Is it possible to run a query on an EF4.0 data context and get all objects of a certain type?
Say the context has books, genres & authors but I only have a generic parameter, t. Is it possible to get all of type just by using this t?
I don't think it is :(
My Python server receives jobs that contain a list of the items to act against, rather like a search query term; an example input:
(Customer:24 OR Customer:24 OR (Group:NW NOT Customer:26))
To complicate matters, customers can join and leave groups at any time, and the job should be updated live when this happens.
How is best to parse, apply and store (in my RDBMS) this kind of list of constraints?
Hey all,
I have a table Logins { Id, AccessTime }, I'd like to write a query that returns 3 columns, Total Logins during a time period, Unique Logins for a time period, and the Id of the user.
I know I could do this with two passes and a join, is there a better way to do it in a single pass?
Thanks,
~P
