Hi i have a yaml file like so
---
data:
- date: "2004-06-11"
description: First description
- date: "2008-01-12"
description: Another descripion
How can i do a "ypath" query similar to xpath for xml ? Something like "get the description where the date is 2004-06-11"
YAML.parse_file('myfile.yml').select('/data/*/date == 2004-06-11')
How do you do it, and if that's possible how can i similarly edit the description by 'ypath' ?
Thanks
When you query the ALL_TAB_COLS view on Oracle 9i, it lists columns marked as UNUSED as well as the 'active' table columns. There doesn't seem to be a field that explicitly says whether a column is UNUSED, or any view I can join to that lists the unused columns in a table. How can I easily find out which are the unused columns, so I can filter them out of ALL_TAB_COLS?
I want to make this kind of query:
create procedure something
@name varchar(13)
as
begin
select * from WORKER
where NAME LIKE "%@name%"
end
For input @name=ho, I want output every row that contains NAME wich sounds "ho",
for example HOuse, soHO, broHOw...
Part of the code:
...where se.DateFrom >= pDateFrom && se.DateTo <= pDateTo select se...
Does not work. There is no any error but the To and From days do not get returned.
How do I query "more than or equal to" and "less than or equal to"?
Thanks :)
Lets say there is some code that executes the following SQL query:
set rowcount n
But n is unknown. Is there any way to know what n was? I'm using Sybase.
Why do I get a 400 - bad request error using the following URL? It is encoded using Server.UrlEncode. The actual path query parameter is C:\Development\Chase\Exports\ChaseExport-090312073930.zip

When user opens a form to modify a record, but instead of changing information, he just clicks the Update button. Which causes the update() function to return 0. However, I consider this case a valid update task. How would I test it, so I can assign a success message?
Is update() returns -1 when SQL query failed or also 0?
Method: Zend_Db_Table_Abstract::update()
Any ideas?
Thanks
Hello!
To empty database table, I use this SQL Query:
TRUNCATE TABLE `books`
How to I Truncate table using Django models and orm?
I've tried this, but it doesn't work:
Book.objects.truncate()
select @[email protected]('*')
for xml raw,type
Above statement will generate following alert:
Msg 6819, Level 16, State 3, Line 2
The FOR XML clause is not allowed in a ASSIGNMENT statement.
This is the query to update table in one database that is of other
Update
test.temp a,
test2.temp b
Set a.name=b.name
Where a.no=b.no;
Now I don't want to write every field i.e a.name=b.name
Is there any solution?
Having a bit of difficulty figuring out how to create a named_scope from this SQL query:
select * from foo where id NOT IN (select foo_id from bar) AND foo.category = ? ORDER BY RAND() LIMIT 1;
Category should be variable to change.
What's the most efficient way the named_scope can be written for the problem above?
Using SQL ManagementStudio 2008 I created SQL 3.5 Compact DB (TestCompact.sdf) and I have created subscription to existing Publication. Using SQL Management Studio it is working. I have transfered TestCompact.sdf to Windows Mobile 5 emulator device and with QueryAnalyzer for Mobile I could query existing tables in TestCompact.sdf. I don't know how to start replication synchronization on that mobile device. Do I need to write some C# code or it is possible do it more simple?
When I do an XMLHttpRequest, I always get redirected automatically to the URL (presumably by the headers of the response). For example, if I query "http://www.stackoverflow.com" I will be redirected to "http://stackoverflow.com".
How can I get that final URL? (http://stackoverflow.com/ in the example)
I checked in the response headers but I cannot seem to find it. (I just used the GET/POST method not HEAD).
Web pages are, by nature, state-less objects. When you click from page to page in an ASP.net application, each request for a page is treated as a brand-new request. We use things like cookies, session-variables, and query strings to maintain state from page to page.
When you log in to an ASP.net web application using Windows Authentication, how does IIS persist your identity between pages?
I have the following XML:
<tests>
<test>1</test>
<test>2</test>
<test>3</test>
</tests>
And I am trying the following query:
CREATE PROCEDURE [dbo].[test]
@Tests xml=null
AS
BEGIN
SELECT
doc.col.value('(test)[1]', 'nvarchar(50)')
FROM
@Tests.nodes('//tests') AS doc(col)
END
But it only returns me a value from the first
What am I missing here?

Consider a news portal like cnn. There is 8 categories. Is there 8 query in every page loading? For eg
SELECT title FROM category where cID = 1
SELECT title FROM category where cID = 2

And for sites with high traffic, would be memcache a good solution?
Thanks in advance
My database has about 30 views, most of which have a reference to another database on this server (call it DB1).
Now, without going into the reasons why, I need to update all those views to DB2, also on the local server.
I would hate to have to do this manually on each view. Is there some SQL query I can run that will replace all occurrences of the string 'DB1' with 'DB2' in all my views?

I am building a website on top of nhibernate. Is there any efficient way to build reports? BY reports, I mean is there anyway to execute a complicated query that grabs random pieces of data? StoreProcedures? Hql?
Can I get single, non mapped values from hql?
