I'm working on a recurring multi-day appointment program. Basically the user can choose a meeting on multiple days of the week over a span of time. For example: Tuesday and Thursday from 10:00 to 10:30 from December 1st 2004 to February 27th 2005.
So I've decided the best way to handle this is to assign a value to each day of the week like so:
MON = 1
TUE = 2
WED = 4
THU = 8
FRI = 16
SAT = 32
SUN = 64
So if the user picks TUE and THU that would be 2 + 8 = 10. The value is unique and seems to work.
So the values would be:
@begin_date = '12/01/2004'
@begin_time = '10:00 AM'
@end_date = '02/27/2005'
@end_time = '10:30 AM'
@recur_days = 10
Now I want to pass the values to stored procedure that will decode the recur_days variable and create entries in a table for each date. I'm struggling to figure out 2 things
1. How do I decode the 10 back into 2(TUE) + 8(THU) ( I think it has something to do with the bitwise AND "&" operator but I'm not sure how to use it.)
2. What is the best way to loop through the date range and create a record for each day?
I have an OLE-DB Command transformation that inserts a row. If the insert SQL command fails for some reason, I use the "Redirect Row" option to send the row to another OLE-DB Command transformation that logs the error on that row to a "failed rows" table. In this table I log the ErrorCode and ErrorColumn values that come with the error path from the first OLE-DB Command.
OK, that's all working great. However, here's the kicker: there's no error description value. The ErrorCode value, naturally, is the decimal form of an HRESULT--for example, -1071607696. Without some further information, however, this code is not useful for troubleshooting.
Has anyone figured out a trick here? I'm not even certain that this is an SSIS HRESULT, since it could for all I know be from the OLE-DB layer, the database layer, or somewhere else.
I have a table column type as nText, however there are some Chinese character stored in that field and it is a messed up as it is not readable.
In my vb.net code, I did Convert to unicode by getting the byte of each character and encode it with UTF8 e.g:
Public Shared Function ConvertToUnicode(ByVal s As String) As String
' Convert To Unicode
Dim MyBytes As Byte() = Encoding.Default.GetBytes(s)
Dim GBencoding As Encoding = System.Text.UTF8Encoding.UTF8
Return GBencoding.GetString(MyBytes)
End Function
This works well but ,the problem is that it slows down the process quite alot, and I wonder are there any text encoding method I can use in SQL that can run when i do the SELECT Statement?
SELECT Convert(MyNTEXTColumn) .... something like that?
This is a crosspost, I also asked this question in the learnvisualstudio.net forum. I'm trying to engineer a bit of code in SQL that "decodes" a value stored in a table that represents an array of boolean values, stored using bitwise operations. I have the number, a reference of bit positions for each item, and the actual items checked per the program that normally processes this value. I'm trying to write a sproc that will perform actions based on the booleans in my list, but I can't get the same results the interface gives me. Here's an example: Value is 66756 Bit positions 2, 6, 7, and 10 should all return true. I was trying to deduce this using the following:
but that doesn't work at all. It's my (broken) translation of the code normally used to display this value as a checkbox, which comes from VB6 and looks something like this:
I was doing a SUM on my returned rows and i found that what i really want is an aggregate bitwise OR on all the returned rows. Do you know what's the function for that?
I am new to bitwise thing in MSSQL.Let's suppose there's a table of favorite foodsinsert int fav_foods(food_name,bitwiseVal)values('Pasta',1)insert int fav_foods(food_name,bitwiseVal)values('Chicken',2)insert int fav_foods(food_name,bitwiseVal)values('Beef',4)insert int fav_foods(food_name,bitwiseVal)values('Fish',8)insert int fav_foods(food_name,bitwiseVal)values('Pork',16)How do I write query to find people who selected more than one item andselected items from "Pasta, Chicken, Beef, Pork"(but not fish)?I hope my question is not confusing.....
I am trying to get a culmulative Bitwise OR operation on a column by query - rather than using a CLR function.
The problem is shown below:
CREATE TABLE #Operations ( PK INT NOT NULL IDENTITY(1,1), UserName VARCHAR(50) NOT NULL, UserProcess VARCHAR(50) NOT NULL, ServerOperation VARCHAR(50) NOT NULL, Permission INT NOT NULL );
[Code] ....
So Far I've tried SUM - wrong results, and STUFF - which doesn't seem appropriate for bitwise operation - neither give useful results.
-- SUM Operation - fails SELECT DISTINCT UserName, ServerOperation, SUM(Permission) AS Permission FROM #Operations
[Code] ....
It may be possible to materialise the permissions each time one is changed (e.g. by to use a cursor ), however I would prefer a query or function or combination to generate the result.
I would like to do something like a SELECT * FROM Files WHERE (Attributes & ?) but the & operator isn't recognized. I looked at the documentation sample for it and in the sample the & operator isn't used in the WHERE clause so I thought that might be the reason but I still can't get the operator to work. So even the doc sample code for it doesn't work.
HI, i am trying to make query that has computations with it. but when there's a point computing between int and float i had to use cast() function to convert certain data types. somehow it only works on converting float to integer because when i'm converting an integer into float inorder to be computed with a float it bombs. my query is like this ....
SELECT cast(((cast(((lat - (SELECT LAT FROM TPS_ZIPUSA WHERE ZIP_CODE = 00210)) * 69.1) AS int) ^ 2) + (cast((69.1 * (lng - (SELECT Lng FROM TPS_ZIPUSA WHERE ZIP_CODE = 00210)) * (COS((SELECT LAT FROM TPS_ZIPUSA WHERE ZIP_CODE = 00210) / 57.3))) AS int) ^ 2)) AS float) ^ .5 FROM TPS_ZIPUSA
.5 is where the query bombs. any idea why is this happenning?
Hello,I am writing a query to select records added to a table today, in the last 3 days, in the last 7 days, and so on.Here is what I have (which seems that its not working exactly). -- total listed today SELECT COUNT (*) FROM mytable WHERE DATEDIFF(Day, mydatecolumn, getdate() ) <= 0-- total listed yesterday SELECT COUNT (*) FROM mytable WHERE DATEDIFF(Day, mydatecolumn, getdate() ) <= 1-- total listed in the last 3 days SELECT COUNT (*) FROM mytable WHERE DATEDIFF(Day, mydatecolumn, getdate() ) <= 3I'd like to be able to select the count for records added within the last X number of days. Can someone please help me out? Thanks so much in advance.
We are facing a problem while passing a string containing the "&" character into Full Text search CONTAINS predicate. The records that do have this character are not being returned by the search.
I'd like to raise two questions:
1) Is there any special way to escape this character? 2) Does FTS index it at all?
We have tried all known (to us) ways of escaping like doubling the character, using char(38), using ESCAPE etc..Nothing seem to work. Any help would be appreciated.
How would I bring back a column that shows all the days from the begining of the year to the current date. Also make sure this moves onto the next year.
Hey heyI've written my site in asp.net 2 and have set up roles and various logins etc which work beautifully locally. Now, when i upload to my host I get the: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)The thing is, I've checked my connection string a million times and it's perfect, I've also checked all the database settings on my host and they're all fine. However, when i use SQL Server Management Studio Express to copy my database from the local to the remote server (from a tutorial on these forums), I get the "Operation completed successfully" message yet when I expand my tables, there is no data in them. I've tried copying and pasting the data in manually but i still get the same issue. It's driving me absolutely insane! Anyone any ideas?Thanks
Hi all, I have a table in which I have two fields in my DB. FromDate and ToDate. Both are stored as Varchar(MAX). I would like to have an SP which gives me the Days in Between them. Regards, Naveen.
Is there any way to find out in sql server that whether it is Monday to friday or saturday sunday.I have to write a stored procedure in which the logic shoukld be done only if there is a weekend.if saturday or sunday select * from status_tempPlease let me know if there is any function that is available in sql
Hi, I just want to know, is there anything more better solution than this one to find out the no of days in a month ? I have done this but I am not satisfied,anybody has a smarter solution? Plz comment..
My Solution :
/* check leap year*/ if year(getdate())%4<>0 set @noofdays=(select case month(getdate())-1 when 1 then 31 when 2 then 28 when 3 then 31 when 4 then 30 when 5 then 31 when 6 then 30 when 7 then 31 when 8 then 31 when 9 then 30 when 10 then 31 when 11 then 30 when 12 then 31 end ) else set @noofdays=(select case month(getdate())-1 when 1 then 31 when 2 then 29 when 3 then 31 when 4 then 30 when 5 then 31 when 6 then 30 when 7 then 31 when 8 then 31 when 9 then 30 when 10 then 31 when 11 then 30 when 12 then 31 end)
Hi, I used the following query to update my columns according to the change of time and days of the week. But my query is not working as it should. Today is Tuesday and the time now is 9am so according to my query Mon_Night column should be updated but Sat_Night column is being updated when i execute the query. Please advice..
Condition 1. Let's say, the current date is 5/9/2008 2. Result only display the last 7 days data. From above data. it's mean only pickup from 5/3/2008 to 5/9/2008 3. Every Main_ID only pickup the MAX Hit 4. Diff (column on the fly) = Hit - Hit2
Hello, I have a table with a field Expiration of smalldatetime. I want to only display the data that has 60 days or more between Expiration and todays date. Any help would be highly appreciated.
