You could always try asking a question.

the OP does not have a question, he wants to get a question, a random one.

Why are you getting it in back-end move for front-end it will works.

I don't completely agree with you, pending on the size and design structure of the question system. If you have multiple categories each containing a couple of thousand questions. Totalling in the millions then it would be less then optimal to do it in the application. Or a scenario where the same logic would have to reside in multiple applications.
So doing it database or application side really depends on the setup of the entire application.

Yes This is your point of view and I 100 % agree with you.

Hi
I am trying to convert an Oracle query to SQL. But i am totally confused thinking how to proceed. For some of the oracle packages , am not able to find an equivalent SQL function
Here is my Oracle query
cursor c_fields(c_xml XMLTYPE) is
select DBMS_XMLGEN.convert(extract(value(x), '//field/@name').getstringval(),1) FLD_NAME,
extract(value(x), '//field/@resultCol').getstringval() RESULT_COL,
extract(value(x), '//field/fieldConfiguration/@isAttachmentAllowed').getnumberval() AllOW_ATTACHMENT,
extract(value(x), '//field/@key').getnumberval() FLD_ID
from TABLE(XMLSEQUENCE(EXTRACT(c_xml, '//table/field'))) x;
I need to convert this to SQL query. In SQL we dont have parameterized cursor concepts. However to some extent we can achieve the functionality by using "WHERE" condition. But in this query, am not able to trace out how can i write the equivalent SQL functionality since "FROM" part itself is using the parameterized cursor.
Please help.
Thanks

My first choice would be to refactor the database unless that code is touched very seldom. That sort of meta data solution is very inefficient.
But after that I would use dynamic sql. You create a varchar with equivalent sql in it, specifically the extracted table name. I would probably extract the rest as well.
Then you use 'execute' to execute the varchar.

Hi, I am wondering if there is a way of proofing a stored procedure in terms of the datetime localisation. For example, in the C# we may use the web.config or machine.config to set the application's localised date settings:
globalization uiCulture="en" culture="en-GB">
This helps when we do a date comparison in a static class of ours to return a certain rating factor.
Is there an equivalent way of us checking whether or not the date we pass into the stored procedure is in e.g. UK format and will be compared against our dates in the UK format too? We have 2 datetime columns, DateEffectiveFrom and DateEffectiveTo in our table and we use those dates to compare with the date passed in to return the relevant data.
Thanks

Just to clarify one thing: if your columns are datetime columns, why do you need to worry about date formats? You can just compare one datetime with another.
Is the parameter to the stored proc being passed as a string/varchar and you need to figure out what format it is in order to do the comparison?

Hi David, the parameter will be a datetime. I need to find which date range this falls in.
For example, I pass in the date 11/11/2010 and the columns are:
ID StartEffDate EndEffDate Rate
1 01/01/2000 31/12/2003 1.05
2 01/01/2004 31/03/2011 1.15
3 01/04/2011 01/01/2012 1.25
I need to return the appropriate Rate, e.g. in this case 1.15

date formatting is a human thing, it does not relate to databases at all, unless you make a mistake. What you should do is define datetime fields, and pass DateTime SQLParameters, that avoids all datetime formatting issues on the DB side; obviously you still have to deal with the datetime formatting in the GUI, however that is the only place it should matter (and there you should follow the system's regional settings).

Luc's answer is still valid as the correct way of doing things, but if you want to pursue the hard way you can start looking here[^] for SQL Server.

Hi,
Can anyone help me with small sample for :
How to compare same field in two tables in sql server 2005 using C#
thanks

As I getting, you need to get value from two table based on same value. if so then Join Will be better option for your query.
Joins allow you to view data from related table in a single result set.
you can use any one of Three way of join.
Inner Join,
Outer Join,
Left Join,

Your question confusing little bit. Based on my guess you may use Alias.(I think you mentioned Same field like same field name in two tables)
SELECT A.*, B.* FROM TableA AS A, TableB AS B WHERE A.Field1 > B.Field1
If not then let us know & mention clear details in your question.

I'm new in the database world...
I want to know if its possible to add image ( simple bitmap or jpeg ) to the database ?
If this is possible => how can i get and set the image from C# code ?
Thanks for the help.

Hi,
There is an "image" data type in SQL Server which is basically a binary datatype. http://msdn.microsoft.com/en-us/library/ms187993.aspx[^]
Storing binary inside a database is generally strongly advised against though. Before you do that you might want to check if using the filesystem could be a better solution.
|
|
|
|
|
Yes you can insert image or retrieve it from your Database by using BLOB(binary Large object) approach in which an image file is convert into Binary data which is compatible to store data in Database.
Google has a lots of resource for this purpose. whatever i suggest you to move for this given link
Save An Image Into SQL Server 2000 Database[^]
