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.

Is there a way to do a logical exclusive OR (XOR) in sql server?
I'm trying to do this in where clause, something like:
WHERE
(not exists (select 1 from table a where a.date > '01/30/03') XOR
exists (select 1 from table a where a.date < '01/30/03'))
Thanks!

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.

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?
Thank you

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

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

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.

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).

I have a table adapter query with a like clause that I can't get to work. The field is "Type", so I have "LIKE '%@Type%'". When I click the Execute Query button to test, not only does nothing get returned, I don't get the chance to enter the parameter. If I change LIKE '%@Type%' to say, LIKE '%book%', the appropriate records are returned. I actually need to check two parameters. If I ad the second parameter, the where clause becomes(Type LIKE '%@Type%') AND (SendState = @SendState)When I test the query, a screen pops up to let me enter the state, but not the Type. I can't see anything wrong with the query, but something must be. Diane

I am having some trouble using a sub query. I want to use the red part as a sub query because I have to alter some values based on the NcodeM that gets assigned to each record. As a stand alone query the red part works well. When I run the whole thing I get error message:

I am having trouble figuring this one out.
I have a table named studentgrades
In it, it contains studentid, teacherid, classgrade
If I do this code it gives me the count of student that made an "A" grouped by teacherid
select
teacherid,
count(grade) as GradeACount
where
classgrade between 90 and 100
from
studentgrades
group by
teacherid
ok this seems simple enough...if I manilpulate the where clause I can get "B","C" and "D" student counts.
My question is how can i get a dataset to return
teacherid,GradeACount,GradeBCount,GradeCCount,GradeDCount
all in one query...I am trying to automate a report so that school districts can pull their own queries via Reporting Services.
I appreciate your time.

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

Our Client/Contact database works like this:
CLIENTDB - This table holds the records of all Clients, Contacts, Suppliers, etc. They are defined as one type of record or another by the 'Contact_Type' field - Clients are type 'B', Contacts are 'D', etc.
Contacts are often linked to a Client, but don't have to be. These links are stored in the LINKS table.
So, what I'm trying to do, is generate a report of all Contacts that aren't linked to Clients but possibly should be because they share a company name. The SQL I've used to get this info is as follows:
SELECT *, CLIENTDB.Formal_Name as FN
FROM CLIENTDB
WHERE (CLIENTDB.Contact_Type = 'D')
AND (NOT EXISTS (SELECT * FROM CLIENTDB, LINKS JOIN CLIENTDB as CB ON CLIENTDB.Contact_ID = LINKS.Link_Record_ID))
AND (EXISTS (SELECT * FROM CLIENTDB WHERE (CLIENTDB.Contact_Type = 'B') AND (lower(CLIENTDB.Formal_Name) LIKE '$FN')))
The problem is the final AND condition - I want this to filter the results down to only those Contacts that have a Formal_Name like an existing Client, but when I add or remove this one line, it makes no difference to the output.
Any suggestions greatly appreciated
Thanks, Nick

Hi, I have created a query (using SQL 2005) that will pull the people who have spent the most on tickets purchased:
Select P.Passenger_ID, Passenger_Name, Ticket_Price
From Passenger P, Ticket_Purchase T
Where P.Passenger_ID = T.Passenger_ID
Group By P.Passenger_ID, Passenger_Name, Ticket_Price
Having Ticket_Price >= All (Select Max(Ticket_Price)
From Ticket_Purchase
Group By Ticket_Price);
Passenger_ID Passenger_Name Ticket_Price
---------------------------------------
132812298 Nice,Richard 1750.00
234890032 Franco,Sylvia 1750.00
339209841 Kim,Jongouk 1750.00
385894857 Uribe,Gloria 1750.00
(4 row(s) affected)
I now want to be able to only choose the Passenger_ID's from above who are not listed in another table called Frequent_Flier, which should leave me with only 2 records not 4.
I am wondering if I add the below to the first query to eliminate those passengers in the Frequent_Flier table:
NOT IN (Select Passenger_ID
From Frequent_Flier);
When I add it to the Where clause I get an error. Should I be sub-querying that differently or is there a better way to do this.
Thanks for any help you can offer.

I want to fill in a field whose name is stored in a variable. This code runs, but the field is not filled in afterward. I think I'm doing something wrong:
SET @field = N'bindery'
SET @ordernum = N'SM38948M08'
UPDATE Orders
SET @field = GETDATE() + 5
WHERE ordernum = @ordernum
My problem is related to using the @field variable in the UPDATE query.
How do I fix this?
Thanks!

Hi,
I am having trouble getting my query right. i am using a stored procedure to retrieve this data and bind it to my grid view.
Problem: I can't associate a field with a column that i am returning with my record set.
Details: I have query that i want to return 9 columns (UserName, Pre-Approved, Processing, Underwriting, Conditioned, Approved, Docs Out, Docs Back, Conditions Met). The username column lists all loan agents. I want the other 8 columns to list the name of the borrower (crestline..borrower.lastname) that is associate with that loan agent and that loan state. Each time a record is found where there is a valid loan agent (UserName) that meets the 'where' conditions, there will be a borrower. the 'LoanKey' field is a primary key that lets me get the borrower name from the borrower table. I dont know how to construct my query such that those borrower names get associated with their respective column header.
if the query works, my Gridview should look like this ('Name' refers to the borrower name)
UserName | Pre-Approved | Processing | UnderWriting | Conditioned | Approved | Docs Out | Docs Back | Conditions Met
Bob | | | | Name | | | |
Bob | | Name | | | | | |
Bob | | | | | | | Name |
Steve | | | Name | | | | |
Steve | | | | | | Name | |
Here is my sql call:
SELECT cfcdb..users.username, crestline..borrower.lastname,CASE WHEN crestline..loansp.LoanStatus='Pre-Approved' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Pre-Approved',CASE WHEN crestline..loansp.LoanStatus='Processing' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Processing',CASE WHEN crestline..loansp.LoanStatus='Underwriting' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Underwriting',CASE WHEN crestline..loansp.LoanStatus='Conditioned' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Conditioned',CASE WHEN crestline..loansp.LoanStatus='Approved' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Approved',CASE WHEN crestline..loansp.LoanStatus='Docs Out' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Docs Out',CASE WHEN crestline..loansp.LoanStatus='Docs Back' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Docs Back',CASE WHEN crestline..loansp.LoanStatus='Conditions Met' THEN crestline..loansp.LoanStatus ELSE NULL END AS 'Conditions Met'FROM cfcdb..usersinner join (crestline..loansp inner join crestline..borrower on crestline..loansp.loankey = crestline..borrower.loankey)on crestline..loansp.fstnamelo=cfcdb..users.firstname AND crestline..loansp.lstnamelo=cfcdb..users.lastnameinner join cfcdb..users_roleson cfcdb..users.username = cfcdb..users_roles.usernamewhere cfcdb..users.active = 1 AND cfcdb..users_roles.groupid = 'agent'AND crestline..loansp.enloanstat <> 'Closed' AND crestline..loansp.enloanstat <> 'Cancelled' AND crestline..loansp.enloanstat <> 'Declined' AND crestline..loansp.enloanstat <> 'On Hold'order by cfcdb..users.username asc

Given the following tables:
[Members]
-memberID (PK)
-memberName
[Questions]
-questionID (PK)
-questionText
[Surveys]
-surveyID (PK)
-surveyName
-surveyDescription
-surveyType (FK)
[SurveyQuestions]
-surveyID (PK/FK)
-questionID (PK/FK)
[SurveyQuestionMemberResponse]
-surveyID (PK/FK)
-memberID (PK/FK)
-questionID (PK/FK)
-yesResponse(bit)
-noResponse(bit)
-undecidedResponse(bit)
How can I write a query to return the results for a given survey for all members (including members who have not given responses) given the surveyID.
In the [SurveyQuestionMemberReponse] table I record survey results for any members who have answered the survey. However, if a member has not responsed to the survey they will not have a record in this table.
I want to return a list of members with their response to each question in the survey. If a member has not given a response I would like to indicate they have not responded to the survey and they should still appear in the list.
When I attempt to write a query to UNION the results of a query aimed at gathering all of the results in the [SurveyQuestionMemberReponse] to all of the people in the [Members] table I recieve an error when I include the questionText field in my result set.
The error indicates:
The text data type cannot be selected as DISTINCT because it is not comparable.
Can someone please point me in the right direction. I suspect I am going about this all wrong.
[NOTE] The 'surveyType' in the [Surveys] table indicates which subset of members a given Survey should be available to. For this example let's just assume that every survey should belong to all members.
Thanks,
Zoop

I'm working with a database that is poorly normalized and am doing my best to increase the speed of our queries (changing the database itself is not an option right now). Any help with the following situation would be very much appreciated.
There are two tables involved, described below.
DataTable:
Code Snippet
CodeA char(4),
CodeB char(4),
CodeC char(2),
ColA float,
ColB float,
ColC float,
...
ColZ float
NameTable:
Code Snippet
Abbr char(2),
FullName varchar(50)
In the DataTable, the columns named ColA, ColB, ColC, etc., are described in the NameTable where Abbr would be A, B, C, etc., and FullName would be a "nice" text version describing what's stored in that column. For instance, a record in the NameTable might include Abbr = 'A' and FullName = 'Computer Science', and that means that ColA in the DataTable refers to 'ComputerScience'.
The table I'm trying to optimize the creation of in our ASP.NET application needs to have column headings that could be retrieved like this:
SELECT DISTINCT CodeB, CodeC FROM DataTable WHERE CodeA = @CodeA
(Note that CodeC is really just a different representation of CodeB--think 4-digit year vs. 2-digit year--for any given CodeA.)
The row headings for the table could be retrieved like this:
SELECT FullName FROM NameTable
The cells of the table at any given intersection of a row heading and a column heading can be retrieved like this:
SELECT Col? FROM DataTable WHERE CodeA = @CodeA AND CodeB = @CodeB (this selects a single value)
Where the ? of Col? is determined by the Abbr version of FullName shown in the row heading, and @CodeB is determined by CodeB from the column heading.
Right now this table is generated using a lot of loops in the code of the page that require it to query the database for nearly every cell in the table. Even with this poor database design, there has to be a better way than that. I'm hoping there is a way to create a stored procedure that uses temporary tables and joins, or views, or something like that to create the table on the SQL Server and just send the data to the ASP.NET page in a form that can be directly databound to a GridView.
Thanks in advance for any help!

Please help.
Has anyone seen a problem querying Excel or Access database when the "LIKE" clause is used with the "*" wildcard? The problem I'm seeing is that the query fails to return a dataset whenever "*" wildcard is used.
For Example,
sQry="Select * From [EmployeeData$] WHERE Id LIKE 'AAA'" 'query WORKS
sQry="Select * From [EmployeeData$] WHERE Id LIKE 'AAA*'" 'query does NOT WORK
Assume that Table name is "EmployeeData", with "ID", "Name" and "Birthdate" as Fields.
Data:

Hi,

A problem about many to many relationships from an SQL beginner. Here's a contrived abstract example, as I'd prefer not to give away specifics.
Imagine I have two tables: users, food
The relationship (to like) is many-to-many so I've got a link table, which might look like the below:
andrew, apples
bob, banana
bob, apples
chris, carrots
chris, apples
chris, banana
I want to select users who like bananas and apples exclusively.
The answer should be 'bob' ONLY. select * from users inner join food on <IDs> where food in ('bananas','apples') isn't suitable , because it'll also return 'chris' who should be disqualified (because he also likes carrots).
Apart from potentially being bad DB design (although this is an abstract example; I do have ID numbers), can anyone suggest how to get this in a scalable way?

Anybody know how a SELECT statement can generate an exclusive lock on a table ?
I always thought that SELECT's take out shared locks. Is this something to do with temporary tables generated by ORDER BY's and DISTINCT ?
Rogue SQL below (from Site Server).
SELECT A.i_Dsid, A.i_Aid, A.vc_Val, A.i_Val, A.dt_Val, A.img_Val FROM Object_Attributes A, ( SELECT DISTINCT L.i_Dsid FROM Object_Lookup L , Object_Attributes OA2 (index = IND_vc_Aid) WHERE ((( L.i_ObjectClass = 9999 )) AND ( OA2.vc_Val LIKE ( '999999999.9999999%' ) AND OA2.i_Aid = 99)) AND (L.i_Container_Dsid = 99) AND ( OA2.i_Dsid = L.i_Dsid )) AS B WHERE B.i_Dsid = A.i_Dsid AND A.i_Aid NOT IN( 1, 2, 3, 4, 5 ) ORDER BY A.i_Dsid, A.i_Aid
Can anybody suggest a workaround ? Thanks.

I have created a SQL Agent job that is supposed to essentially duplicate a production database to another database. The code I am using is:
step1
__________________________________________________ ______
declare @sql varchar(8000)
set @sql=''
select @sql=@sql+'kill '+cast(spid as varchar)+char(13)+char(10)
from sysprocesses where dbid=12
--Print (@SQL)
exec(@sql)
step2
__________________________________________________ ________
RESTORE DATABASE HIWDYNARPT FROM PRDBACKUP
WITH REPLACE
__________________________________________________ ______
This works when I test it during the day, however when it runs at night I get the following error in the job log:
Database in use. The system administrator must have exclusive use of the database to run the restore operation. [SQLSTATE 42000] (Error 3101) Backup or restore operation terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
I'm not sure why this happens because I have killed all open threads in step 1, and then create my own new thread in step two. Maybe someone else is initiating a new thread to quickly between the steps???
Anyway, I am trying to use:
__________________________________________________ __
ALTER DATABASE HIWDYNARPT
RESTRICTED_USER
WITH ROLLBACK IMMEDIATE
__________________________________________________ ____
...as an alternative to the T-SQL killing PID's, but SQL 7.0 SP4 does not seem to support restricted user like 2000. It keeps giving me a syntax error. Does anyone have any suggestions?
If I bring step 1 and step 2 together, separated by "GO", could this fix the problem?
Thanks in advance!

Could anybody give a lead as to what I can do get rid off this error please.
I alread tried following:
use master
go
Alter Database dbname set single_user with rollback immediate;
go
Still have the issue. SQL 2005 Server actually did lock the db.
So ran
Alter Database dbname set multi_user;
go
and refresh Query and it switch back to multi user.
But I can't restore db yet.
Thank you
