Hi,
I got used to the xml support and recursive common table expressions of sql server 2005. I am just wondering whether any free dbs like mysql support these requirements nowadays? Thanks.

I am making a windows service to be able to run operations on a sql server database (insert, edit, etc) and invoke Stored Procs.
However, is there a way for me to know the type of the SP? When invoking from C#, I need to knof if it is returning 1 value, or more, or none (so I can use executereader, scalar, etc)?
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.

I have an application that creates a Sql Server 2008 database. When I create the database, I would also like to create a datasource for SSRS.
How can I do this?
hi,
i have to create window service which read the xml file and and take the node's value to connect the sql server and create the log file i have already created window application for that but i don't know how to create win services.
I have this sql query:
SELECT
S.SEARCH,
S.STATUS,
C.TITLE AS CategoryName,
E.SEARCH_ENGINES AS Engine,
S.RESULTS,
S.DATE,
S.TOTAL_RESULTS AS Total,
S.ID
FROM
PLD_SEARCHES AS S
Join PLD_CATEGORY AS C ON C.ID = S.CATEGORY_ID
Join PLD_SEARCH_ENGINES AS E ON S.SEARCH_ENGINES_ID = E.ID
ORDER BY S.DATE ASC
I want to identify if S.STATUS is either 1 or 0 and according to those values to return COMPLETE or PENDING in the query results
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?
For what x is
The expression x IS NOT NULL is not equal to NOT(x IS NULL), as is the case in 2VL
(quote from this answer, which is quoting Fabian Pascal Practical Issues in Database Management - A Reference for the Thinking Practitioner -- near the end of that answer)
My guess is when x IS NULL is NULL, but I cannot guess when that would be (i.e. I haven't checked the SQL standard).
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()
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?
im using this sql query to create an index:
$query = "CREATE INDEX id_index2
ON countries(geoname_id, name)";
but how do i update the index when new entries are added?
should i run a php script with the update query in CRON and run it every night?
is this best practice for automated index updating?
Has anybody done any benchmarking/evaluation of the popular open-source embedded SQL DBs for performance, particularly write performance? I've some 1:1 comparisons for sqlite, Firebird Embedded, Derby and HSQLDB (others I am missing?) but no across the board comparisons... Also, I'd be interested in the overall developer experience for any of these (for a Java app).
We have two tables:
Vehicle: Id, RegistrationNumber, LastAllocationUserName, LastAllocationDate, LastAllocationId
Allocations: Id, VehicleId, UserName, Date
What is the most efficient (easiest) way to update every row in Vehicle table with newest allocation? In SQL Server I would use UPDATE FROM and join every Vehicle with newest Allocation. Oracle doesn't have UPDATE FROM. How do you do it in Oracle?
Money, Staff, Skill and preference to open source or commercial is neutral. Lets take the best of the best programmers (for arguments sake) and think about this:
What will perform better overall:
PHP & MySQL
or
ASP.Net & Microsoft SQL

looking for Performance, and Speed).

id VisitNo Weight

Here's the situation. I have a bunch of objects that implement Serializable that I want to store in a SQL database. I have two questions
Is there a way to serialize the object directly into the database
Is that the best way to do it or should I
Write the object out to a formatting String and put it in the database that way and then parse it back out
Write each member to the database with a field that is unique to each object
What is more efficient - handling with case statements in sql or handling the same data using if statements in code. I'm asking because my colleague has a huge query that has many case statements. I advised her to take stress off of the DB by coding the case statements. I've found that it is more efficient...but why?
Somewhat new to SQL queries and I need a little help with my join.

Anyone able to help?
An insert statement with a large number of values returns 'Error converting data type varchar to numeric.'
How can I find which value actually triggers the error?
MS SQL Server 2008 is used.
I'm trying to use a dynamically generated fully-qualified table name in sql server 2008. For example, this does not work:
select max([id]) from @dbName+N'.[T1]'
This will give an error like:
Msg 102, Level 15, State 1, Line 73
Incorrect syntax near '+'.
I know that something like this works:
declare @qualifiedTable varchar(200) = @dbName+N'.[T1]'
select max([id]) from @qualifiedTable
But I have to do this LOTS of times so I would really like to do it in line. Is it possible?
Hi,
I don't see a LINQ option when picking a data source for a grid view - any ideas?
I just upgraded to Visual Web Developer 2010. I see the other options like SQL etc.
Thanks!
