Bitwise && Operator Does Not Work

Jan 15, 2007

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.

Help: Why IN-Operator With Select-Statement It Doesn't Work? But With Given Values It Works

Jun 4, 2007

Hello to all,
i have a problem with IN-Operator. I cann't resolve it. I hope that somebody can help me.
I have a IN_Operator sql query like this, this sql query can work. it means that i can get a result 3418:
declare @IDM int;
declare @IDO varchar(8000);
set @IDM = 3418;
set @IDO = '3430' 
select *
from wtcomValidRelationships as A
where (A.IDMember = @IDM) and ( @IDO in (3428 , 3430 , 3436 , 3452 , 3460 , 3472 , 3437 , 3422 , 3468 , 3470 , 3451 , 3623 , 3475 , 3595 , 3709 , 3723 , 3594 , 3864 , 3453 , 4080 ))
but these numbers (3428 , 3430 , 3436 , 3452 , 3460 , 3472 , 3437 , 3422 , 3468 , 3470 , 3451 , 3623 , 3475 , 3595 , 3709 , 3723 , 3594 , 3864 , 3453 , 4080 ) come from a select-statement. so if i use select-statement in this query, i get nothing back. this query like this one:select *
from wtcomValidRelationships as A
where (A.IDMember = @IDM) and ( @IDO in (select B.RelationshipIDs from wtcomValidRelationships as B where B.IDMember = @IDM))
I have checked that man can use IN-Operator with select-statement. I don't know why it doesn't work with me. Could somebody help me? Thanks
I use MS SQL 2005 Server Management Stadio Express
Thanks a million and Best regards

In Query Builder Design View, How Does The Filter Operator MDX Work?

Nov 12, 2007

Good morning all,

I have searched everywhere for this and I can't find any information on it. When I use the Query Builder, in the top pane, the Filter pane, there are five columnsimension, Hierarchy, Operator, Filter Expession and Parameters.

In the dropdown for Operator, one of the choices is MDX. I cannot find any documentation on how to use this operator. I want to limit my filter to SELF_AND_AFTER, and I am hoping that this is possible using this operator. I know how to hand code it, but I have a ton of other tweaks to make to the query, so I want to use the Query Designer as much as I can.

Does anyone have any links to documentation on how to use this operator?

Thanks,
Kathryn

Bitwise Help!

Nov 27, 2007

Hi,

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:




Code BlockSELECT CONVERT (BIT, <value> & (2 ^ <position>))





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:




Code Block.ListItems(CStr() & "_").Checked = CBool <value> And (2 ^ <position>))





Can anyone tell me what I'm doing wrong? Thanks in advance.

Bitwise NOT Operation

Sep 6, 2006

I was looking into some of the System stored procedures like sp_denylogin, sp_grantLogin etc. I found bit wise operations like

update master.dbo.sysxlogins set xstatus = (xstatus & ~1) | 2, xdate2 = getdate()
where name = @loginame and srvid IS NULL

How does the bitwise NOT(~) works with different datatypes like INT, SMALLINT and TINYINT?

Look at the following sample code and result. I just wanted to understand how it works with int and smallint


declare @a int
declare @b smallint
declare @c tinyint

select @a = 1, @b = 1, @c = 1

select @a=~@a, @b= ~@b, @c= ~@c

select @a, @b, @c

Result
~~~~~
-2-2254

Thanks in advance

Decoding Days Bitwise AND

Nov 11, 2004

Hello All

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?

Regards
Russ

Aggregate Bitwise OR On A Column

Oct 22, 2014

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.

Query Trouble Regarding Bitwise Exclusive

Feb 25, 2001

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?

by the way, i'm using sql server 7.0.

francis,

SQL 2012 :: Custom Bitwise OR Aggregate Function

Mar 18, 2014

I want to create a custom bitwise OR aggregate function.

I want to use it like the built in aggregate functions (MIN, MAX etc.)

SELECT dbo.bitwise_or(bit_string) FROM table

where bit_string is a nvarchar(3)

so for example if the table contains two rows ('100', '001') the above query should return '101'

I would like to implement this as a CLR function/assembly with the aggregate below:

CREATE AGGREGATE dbo.bitwise_or (bit_string nvarchar(3))
RETURNS [nvarchar(3)]
EXTERNAL NAME [Aggregate].[bitwise_or]

I have followed this post to implement amedian aggregate function [URL] ..... but there is a lot of code (not sure what is really needed in my case).

Escaping Bitwise In Full Text Search 2005

Feb 6, 2007

Hi,

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.

Thanks,
Alex

Invalid Operator For Data Type. Operator Equals Boolean AND, Type Equals Datetime.

May 18, 2004

I am getting a error message saying: Invalid operator for data type. Operator equals boolean AND, type equals datetime.

I traced the pointer to @gdo and @gd, they are both dates!

INSERT INTO AdminAlerts values (CURRENT_USER, 'UPDATE', getDate(), @biui, 'Updated booking, ID of booking updated: ' & @biui & ', Booking date and time before/after update: ' & @gdo & '/' & @gd & ', Room number before/after update: ' & @rno & '/' & @rn & ' and Customer ID before/after update: ' & @cio & '/' & @ci)


If I cut that two dates out it works fine.
Could someone tell me the syntax to include a date in a string :confused:

SQL LIKE Operator And %

Jan 14, 2008

Just a quick question that I really couldn't find using google or anything because it was too bland.
How do you return the whole database while still using the LIKE operator.
I have a textbox that you can use to search the database but I want all the data to be displayed underneath the box so you can "browse" the data if you don't know the name of what you are looking for.
What would I put as the default value?  I used just defaultvalue="%" and that worked in 1 area, but not another.  Is this the right way?
Thanks,
Chris

SQL AND/OR Operator

Apr 30, 2008

I have a query and for the life of me I cant figure it out.
I have a web form with a number of textboxes on it e.g. Title, subtitle, isbn. I also have a search button. This search page allows a user to enter any combination of fields in the form and then when they click the search button, a datagrid is diaplyed showing the results (gets the results from a SQL DB).
 I have got the code working if the user selects say one item, but I dont know how to allow it so that the user can enter any combination of items in the form and the search button will search for it based on what the user says. I think im gettng confused with my logical operators in the sql statement.
If any one can take a look I would be greatful.public void BindData(){String @BookID = TxtBookID.Text;String @Title = TxtTitle.Text;String @Subtitle = TxtSubtitle.Text;String @ISBN = TxtISBN.Text;String @AuthorFName = TxtForename.Text;String @AuthorLName = TxtSurname.Text;
SqlDataAdapter ad = new SqlDataAdapter("SELECT Book_ID_Internal, Title, Subtitle, ISBN, Edition, Publication_Date, Author.First_Name, Author.Last_Name FROM Book, Author WHERE Book.Author_ID = Author.Author_ID AND Book.Book_ID_Internal = '" + @BookID + "' AND Book.Title = '" + @Title + "' AND Book.Subtitle = '" + @Subtitle + "' AND Book.ISBN = '" + @ISBN + "' AND Author.First_Name = '" + @AuthorFName + "' AND Author.Last_Name = '" + @AuthorLName + "'", conn);DataSet ds = new DataSet();ad.Fill(ds, "Book");GridView1.DataSource = ds;GridView1.DataBind();}

Between Operator

Jun 6, 2006

Hi,

I'm having problems using the between operator in a query statement.

Select *
from <mytable>
where date between @date1 and @date2

The date values with a hour specified, aren't returned. What is the approach you would recommend here? 

Thx

EDIT: by playing with this problem I've figured out I can append the hour to the date like this: <date> between @fromDate + '00:00:00' and @toDate + '23:59:59'

this seem to work, but I'm not sure if this is correct

The only problem I am having is figuring out how to allow them to choose the operator (=, <, >, <>, etc) from a dropdown list. Does anyone have any suggestions on how to do this with a SqlDataSource control? It is probably something simple and any help would be much appreciated.

Limiting And Using The TOP Operator

May 31, 2004

Hi,

please do help. Have been wrestling with this for about 3 hours and read a buncha forums + searched the tutorial lists.. AARRGH!

Anyhow,

I have to paginate a datalist (and I really can't use a datagrid because of the layout, blame the bluddy graphic designer)

I want to return the top 8 rows, the next 8 top rows and so on.

This is the sql string I have:
'retrieve pagination in order to construct the rest of the sql string
Dim startrec As Integer
If pageno = 1 Then
startrec = 0
Else
startrec = (pageno - 1) * pagesize
End If
' this builds the sql string, getting ONLY the records we need for this. Page size is a constant expressed on the base page
' startrec is the record where I want to start in the db.
strsql = "select top " & pagesize & " * " & strsqlbasic & " and itemID>" & startrec & " order by itemnotes1 asc"
noresults.text = strsql & " <br> " & searchwhat & searchfor

strsqlbasic is constructed elsewhere and is just the 'from X where y = var

Of course, this returns all records where the value of itemID is greater than the value of startrec. How would I change this so it returns the next 4 rows starting from the row number given by the value of startrec?

thanks for any help.
