Hello
How to check a value IS NULL [or] = @param (where @param is null)
Ex:
Select column1 from Table1
where column2 IS NULL => works fine
If I want to replace comparing value (IS NULL) with @param. How can this be done
Select column1 from Table1
where column2 = @param => this works fine until @param got some value in it and if is null never finds a record.
How can this achieve?
Hey,everyone
I have a string 'some.file.name',I want to grab 'some.file'.
To do that,I need to find the last occurrence of '.' in a string.
My solution is :
declare @someStr varchar(20)
declare @reversedStr varchar(20)
declare @index int
set @someStr = '001.002.003'
set @reversedStr = reverse(@someStr)
set @index = len(@someStr) - charindex('.',@reversedStr)
select left(@someStr,@index)
Well,isn't it too complicated?I was just intented to using 'some.file' in a where-clause.
Anyone has a good idea?
I have a TimeSheet table as:
CREATE TABLE TimeSheet
(
timeSheetID
employeeID
setDate
timeIn
outToLunch
returnFromLunch
timeOut
);
Employee will set his/her time sheet daily, i want to ensure that he/she doesn't cheat. What should i do?
Should i create a column that gets date/time of the system when insertion/update happens to the table and then compare the created date/time with the time employee's specified - If so in this case i will have to create date/time column for timeIn, outToLunch, returnFromLunch and timeOut. I don't know, what do you suggest?
Note: i'm concerned about tracking these 4 columns timeIn, outToLunch, returnFromLunch and timeOut
I would like to use newId to generate random numbers. Usually you would use it just once, but I might be generating up to 10 random numbers per newId.
Is it random enough?
Hi, i've got stuck with substring.
On input i've got a string that looks like Sometext (123456). Those digits at the end are random. I need to get only text from that string.
I have a policies in a system
PolRef Start End
POL123 22/11/2012 23/12/2014
POL212 24/09/2012 23/10/2012
POL214 23/08/2012 29/09/2012
I am asking a user for a reporting date, the user enters 24/10/2012 this becomes @StartDate
From this I derive what the quarter is by the month:
set @currentMonth = Month(@StartDate)
if @currentMonth = 1 or @currentMonth = 2 or @currentMonth = 3 begin set @startmonth = 1 set @endmonth = 3 end
if @currentMonth = 4 or @currentMonth = 5 or @currentMonth = 6 begin set @startmonth = 4 set @endmonth = 6 end
if @currentMonth = 7 or @currentMonth = 8 or @currentMonth = 9 begin set @startmonth = 7 set @endmonth = 9 end
if @currentMonth = 10 or @currentMonth = 11 or @currentMonth = 12 begin set @startmonth = 10 set @endmonth = 12 end
I then get a date range:
@quarterStartDate = CAST(CAST(YEAR(@StartDate) AS varchar) + '-' + CAST(@startMonth AS varchar) + '-' + '01') AS Date)
@quarterEndDate = CAST(CAST(YEAR(@EcdDate) AS varchar) + '-' + CAST(@endMonth AS varchar) + '-' + '31') AS Date)
This will give me 01-10-2012 and 31-12-2012. Basically I need a script to only bring back the policies that are in this quarter. The policy doesn't have to span the entire quarter date range, just exist in the quarter date range.
The results expected would be
PolRef Start End
POL123 22/11/2012 23/12/2014
POL212 24/09/2012 23/10/2012
Pol123 appears because it spans over the quarterly date range. Pol212 is there because it expires in that quarter date range. Pol214 does not appear because it neither spans, expires or starts in this quarter.
Any help would be greatly appreciated
I'm diving head first into ASP MVC and am playing around with creating and manipulating a database. I did a search and found this tutorial for creating a database, however when I follow it, I get this error right at the start when trying to add a new database to my fresh, empty ASP MVC 2 project...
A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.
Verify that the instance name is
correct and that SQL Server is
configured to allow remote
connections. (provider: SQL Network
Interfaces, error: 26 - Error Locating
Server/Instance Specified)
The only requirement the tutorial mentioned was SQL Server Express, but when I went to download it, it said it was already installed. I'm assuming it was part of the VS 2010 RC I installed and am running. So I don't know what else I need if I am missing something.
This is all new to me, so I'm sure I'm missing something obvious here and after I'm done posting this question, I plan to do some more research into the topic of databases and how they work with ASP MVC. In the meantime, I was you could help me answer a couple high level questions...
What am I missing/forgetting to do that is causing this error?
Any suggestions for good resources/tutorials that focus on using databases with ASP MVC? I've done a lot of database programming in the past, so I'm familiar with the concepts of relational databases and the SQL language. I wish I could find a good resource for learning how to work with them in an ASP dev environment, as well as a good breakdown of all the related technologies used for working with them (i.e. LINQ to SQL).
Thanks so much in advance for all your help! I'm going to start researching these questions right now.
I have a large historical transaction table (15-20 million rows MANY columns) and a table with one row one column. The table with one row contains a date (last processing date) which will be used to pull the data in the trasaction table ('process_date').
Question: Should I inner join the 'process_date' table to the transaction table or the transaction table to the 'process_date' table?

I read this on msdn:
Views let different users to see data in different ways, even when they are using the same
data at the same time. This is especially useful when users who have many different interests and skill levels share the same database.
For example, a view can be created that retrieves only the data for the customers with whom an account manager deals. The view can determine which data to retrieve based on the login ID of the account manager who uses the view.
My question:
For the above example , i would have to have a column named Userid/LoginId on my table on which the view is created so that i can apply a check option in the view for this column. and then if a user with a name not in that column tries to enter data , then he/she is blocked.
i've created a function for convert minutes (smallint) in time (varchar(5))
like 58 - 00:58
set QUOTED_IDENTIFIER ON
GO
Create FUNCTION [dbo].[IntToMinutes]
(
@m smallint
)
RETURNS nvarchar(5)
AS
BEGIN
DECLARE @c nvarchar(5)
SET @c = CAST((@m / 60) as varchar(2)) + ':' + CAST((@m % 60) as varchar(2))
RETURN @c
END
The problem is when there are minutes < 10 in time
like 9
the result of this function is 0:9
i want that the format is 00:09
how can i do that?

Hi
I am wondering how can do a mass insert and bulk copy at the same time? I have 2 tables that should be affect by the bulk copy as they both depend on each other.
So I want it that if while inserting table 1 a record dies it gets rolled back and table 2 never gets updated. Also if table 1 inserts good and table 2 an update fails table 1 gets rolled back.
Can this be done with bulk copy?
Hi all,
in the data warehouse there's a default language for the measures, and I added a translation for German captions. In a Visual Studio Report Server project, when creating a query with my German OS, the cube and its measures are displayed in German language. When dragging measures to the mdx query windows, the default measure name is used. That's what I want and what I expect, since when writing MDX queries I would like to use the default measure names. But when executing the query, the columns created for each measure is translated to German again. This resuls in having German columns names within my dataset, which I dont want. I'd like to have the english column names.
I already tried to change the connection string to: Data Source=server;Initial Catalog=DataWarehouse;LocaleIdentifier=1033
But that doesn't help, I still see German translations.
Anyone knows how to set a specific translation?
I have the below
Name Date

A 2011-02-01 02:00:00.000
A 2011-03-01 03:00:00.000
B 2011-04-01 04:00:00.000
A 2011-05-01 07:00:00.000
The desired output being
Name StartDate EndDate
-------------------------------------------------------------------
A 2011-01-01 01:00:00.000 2011-04-01 04:00:00.000
B 2011-04-01 04:00:00.000 2011-05-01 07:00:00.000
A 2011-05-01 07:00:00.000 NULL
How to achieve the same using TSQL in Set based approach
DDL is as under

hi all,
I have a db with users that have all this record .
I would like to do a query on a data like
CN=aaa, OU=Domain,OU=User, OU=bbbbbb,OU=Department, OU=cccc, OU=AUTO, DC=dddddd, DC=com
and I need to group all users by the same ou=department.
How can I do the select with the substring to search a department??
My idea for the solution is to create another table that is like this:
---------------------------------------------------
ldapstring | society | site
---------------------------------------------------
"CN=aaa, OU=Domain,OU=User, OU=bbbbbb,OU=Department, OU=cccc, OU=AUTO, DC=dddddd, DC=com" | societyName1 | societySite1
and my idea is to compare the string with these on the new table with the tag like but how can I take the society and site when the like string occurs?????
Please help me
I can't figure out a way to allow more than 4000 bytes to be received at once via a call to a stored procedure. I am storing images in the table that are around 15 - 20 kilobytes each, but upon getting them and displaying them to the page, they are always exactly 3.91 KB in size (or 4000 bytes).
Do stored procedures have a limit on how much data can be sent at once? I double-checked my data, and I am indeed only receiving the first 4000 characters from the varbinary(MAX) field.
Is there a permission setting to allow more than 4k bytes at once?
I would like to create a stored procedure that takes in a string of comma separated values like this "1,2,3,4", and break it apart and use those numbers to run a query on a different table.
so in the same stored procedure it would do something like
select somefield from sometable where somefield = 1
select somefield from sometable where somefield = 2
select somefield from sometable where somefield = 3
select somefield from sometable where somefield = 4
Thanks!
for eg...
SELECT *
FROM ( SELECT RANK() OVER (ORDER BY stud_mark DESC) AS ranking,
stud_id,
stud_name,
stud_mark
FROM tbl_student ) AS foo
WHERE ranking = 10
Here foo is present...actually what it does ?..
I have a simple problem, I think, but I have googled and can't find the solution. I have a cube that has MeasureA, MeasureB and MeasureC. Not all three measures have values for each record, sometimes they can be null, it's depending if it was applicable.
Now for my totals, I need to average but the average must not take nulls into account. Any help will be much appreciated. When I view the measures, the null values show as zeros.
