Hi
Is Entity Framework worth moving to for a new small app? About 10 tables and a WinForms app.
ie the alternative being DataTables/DataRows or Linq-to-SQL
I want to go through a table, and change all instances of 'notify4-N' to 'notify5-N', where N is a number from 1-9. Is there a way to do that in SQL? It would be easy in perl, but I'm not sure the customer even has perl on his servers.
I heard opinion that it make no sense to create indexes when field has less changeability.
Eg if it stores only A,B,C,D values then there wouldn't be benefit of having such index, and further more SQL server will not use it at all when executing query.
I wonder your opinion on that matter?

I updated a table in my MS SQL Server 2008 by accident, I was updating a table from another by copying cell by cell, but I have overwritten the original table. Is there a way that I can restore my table contents as it was?
I have Article table:
id | type | date
-----------------------
1 | A | 2010-01-01
2 | A | 2010-01-01
3 | B | 2010-01-01
Field type can be A, B or C.
I need to run a report that would return how many articles of each type there is per every day, like this:
date | count(type="A") | count(type="B") | count(type="C")
-----------------------------------------------------
2010-01-01 | 2 | 1 | 0
2010-01-02 | 5 | 6 | 7
Currently I am running 3 queries for every type and then manually merging the results
select date, count(id) from article where type="A" group by date
Is it possible to do this in one query? (in pure sql, no stored procedures or anything like that).
Thanks
Hi,
I am getting the following error: Invalid authorization specification
I've narrowed down the error to my connection string. I have verified the server name, database, user & password are correct. Here is the string:
"Provider=SQLOLEDB;Server=xxxxx.db.12345.hostedresource.com;Database=foo;UID=fooUser;PWD=fooPW"
The SQL server is hosted on Godaddy so I don't have access to its settings.
Please help, I've scoured the internet for a solution!
When I rename a table column in Designer mode in SQL Server Management Studio 2008 (both R2 and non-R2) and generate a change script it looks like this:
EXECUTE sp_rename N'table.column', N'Tmp_columnNew', 'COLUMN'
GO
EXECUTE sp_rename N'table.Tmp_columnNew', N'columnNew', 'COLUMN'
GO
What for temporary column name is used? Why don't rename at once?
I'm writing java application that is using both SQLite and MySQL using JDBC.
Are there any differences in SQL for those databases? Can I use same queries for both SQLite and MySQL, or is there any db specific stuff, that doesn't work on the other one?
As far I've worked only with MySQL, so I don't really know much about SQLite.
So i have a SQL table setup as such
CREATE TABLE IF NOT EXISTS `points` (
`id` int(11) NOT NULL auto_increment,
`lat` float(10,6) NOT NULL,
`lng` float(10,6) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM;
And im inserting stuff like
INSERT INTO `points` (`lat`, `lng`) VALUES ('89.123456','-12.123456');
Gives me a row with lat and lng being 89.123459 and -12.123455
Whats up?
I am running unit tests and when I try to insert data in the database and getting it right after, I don't get anything (I have tried with DataAdapter and DataReader).
However when I put a 3 seconds sleep (even with 1 second it doesn't work...) between the insert and the select I get the result.
In SQL Server Profiler I can see the execution, the insert is well done and is completed about 10 miliseconds before the select begins.
I can't find out where this comes
I would like to associate 2 entities using hibernate annotations with a custom join clause. The clause is on the usual FK/PK equality, but also where the FK is null. In SQL this would be something like:
join b on a.id = b.a_id or b.a_id is null
From what I have read I should use the @WhereJoinTable annotation on the owner entity, but I'm puzzled about how I specify this condition...especially the first part of it - referring to the joining entity's id.
Does anyone have an example?
I have a column with comma separated values like 6,7,99.3334. I need write a PL SQL procedure that will give me these values separately. The Length of the column is 40.

We have some JPA entity classes which are currently under development and wouldn't want them as part of the testing cycle. We tried commenting out the relevant entity classes in META-INF\persistence.xml but the hbm2ddl reverse engineering tool still seems to generate SQL for those entities. How do I tell my code to ignore these classes? Are there any annotations for these or should I have to comment out the @Entity annotation along with my changes in persistence.xml file.
Hi,
Is it possible to return a single value and an enumerable collection using LINQ to SQL?
The problem is, I'm trying to do paging across a large recordset. I only want to return 10 rows at a time so I'm using .Skip(20).Take(10) approach.
However I need to know the total number of records so I can show an appropriate page x of y.
Trying to avoid two separate queries.
Thanks

I am created a website using visual studio 2010. On the time of the development of website I am able to access the database.. but after publishing the site using IIS7..i was unable to access the database..the exception occured during that time was "the connection is in the closed state".in IIS7 When I changed the application pool identity to localsystem, it worked.
Data base is installed in the same machine. and server is SQL SERVER 2008 R2
Can't figure this one out... when I execute a select query it shows an explain plan cost of ~4500 and takes ~3 seconds to return. When I wrap that query (no changes) inside of:
select count(*) from (
/*query here*/
)
It times out. It's at 5 minutes and counting now.
I tried this in SQL Developer and Aqua Data Studio -- same results.
Does anyone use the PL/SQL Web Toolkit at all? We use it for internal reporting where I work.
However, does anyone have any experiences of it for producing client-facing websites? General advantages/disadvantages compared to other web languages, such as JSP, PHP etc
