Encrypt By Key Gives Different Results Every Call Time
Aug 9, 2006
Every time I call Encrypt by key I get a different result, although I am encrypting the same clear text,using the same authenticator and using the same key.
I tried calling it twice inside one stored procedure and I got two different results.
Declare @Temp varbinary(8000);
Declare @Temp2 varbinary(8000);
set @Temp = EncryptByKey(Key_GUID('MyKey'),@cleartext,1,@Authenticator);
set @Temp2= EncryptByKey(Key_GUID('MyKey'),@cleartext,1,@Authenticator);
Select @Temp,@Temp2;
when executing this stored procedure, the value of @Temp is differnent from the result of @Temp2, and the same thing happens without using an authenticator.
Is there something going behind in the encryption mechanism of SQL server?
If an application makes a connection under a given user, performs the following: - calls a stored procedure which performs an insert, - the insert causes a trigger to be fired - the trigger causes a sql statement to execute against a different database
Questions: * Does the user who called the procedure, also need permissions to this 2nd database ? * What security context does this trigger get executed ?
I have a stored procedure that is being called by my .Net application. The user account that makes the connection has execute permission to the procedure. However, the procedure does an insert which causes a trigger to fire. This trigger does a sql statement against a table in a different database, which the user who is calling the procedure, does not have permissions to access. Im getting an exception when I call the procedure, and it basically says there was a permission error with the user accessing this other database.
The sql listed above does execute the stored procedure called [dbo].[sproom] successfully and returns all the data all the rows from the stored procedure multiple times. However can you tell me the following:
1. How can I have the stored procedure return distinct rows? 2. I want the stored procedure to return selected columns. I tried using the OUTPUT parameter for some of the columns, but I got the error message, "Procedure or function spHomeroom has too many arguments specified.".
A solution might be to change the stored procedure, but I would prefer not to since this is a generic stored procedure that I believe a lot of t-sqls and stored procedures will use.
i have a table of phonecall records detailing amongst other things the time and duration of the call. there is a relationship linking this table to a table of handsets and from there to a table of users. this users table lists the start date the user had the phone. as ever sample data might make this easier to show:
PhoneUsers table
PhoneUserID Name StartDate PhoneID
1 john 1/08/2006 1
2 bob 20/08/2006 1
3 fred 2/08/2006 2
etc
Phones table:
PhoneID
1
2
etc
PhoneCalls table:
PhoneCallID PhoneID CallDate Duration
1 1 10/08/2006 25
2 1 23/082006 20
3 2 23/08/2006 20
i want the following result set:
user calldate duration
john 10/08/2006 25
bob 23/08/2006 20
fred 23/08/2006 20
essentially i am trying to link the phonecalls to the user of the phone at the time of the call. i make the following assumptions regarding the data:
the user is responsible for all calls for a given handset from the 'startdate' until the next 'startdate' for a different user, if such a record exists, if not then for all calls after that date
i have this query: SELECT top 1 DATEADD(year, -2, @sDate)AS ydate which returns 2005-01-01 00:00:00.000,how can i remove the time values and only display the date?
I'm having a hard time to getting back an xml data back from a stored procedure executed by an Execute SQL task.
I'm passing in an XML data as a parameter and getting back resulting XML data as a parameter. The Execute SQL task is using ADO connection to do this job. The two parameters(in/out) are type of "string" and mapped as string.
When I execute the task, I get the following error message.
[Execute SQL Task] Error: Executing the query "dbo.PromissorPLEDataUpload" failed with the following error: "The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 2 ("@LogXML"): Data type 0xE7 has an invalid data length or metadata length.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I also tried mapping the parameter as XML type, but that didn't work either.
If anyone knows what's going on or how to fix this problem please let me know. All I want to do is save returning XML data in the parameter to a local package variable.
Hello, I would like to exclude the time period after 5.30pm and before 8.30am in my results. The time is in a 13 digit timestamp format which is the same as a standard unix timestamp with 3 digits which are microseconds.
I used:
dataadd(ss, TTIME/1000, '1970-01-01')AS time
to create a column with a readable time in it.
Here is a screenshot: http://www.abtecnet.com/timescreenshot.jpg
Can anyone help me with this. Thanks very much. Andrew
Hello~, The table has columns like this. ________________________________ time smalldatetime value1 int value2 int ----------------------------------------------------------
for example, .... '2006-11-16 12:00:00',100,200 '2006-11-16 13:00:00',110,210 '2006-11-16 14:00:00',120,220 ....
The record is inserted at every hour.
I want get daily,monthly,yearly average and display the result ordered by time.
I used SET STATISTICS TIME ON to get execution stats for a query. I found that the CPU Time was sometimes greater than the elapsed time. How is this possible? The query does not use any parallelism since I used the query option MAXDOP 1. Is the elapsed time wait time? Is the total execution time the sum of the CPU time and elapsed time?
I have a lot of rows of hours, set up like this: 0745, 0800, 2200, 1145 and so on (varchar(5), for some reason).
These are converted into a smalldatetime like this:
CONVERT(smalldatetime, STUFF(timestarted, 3, 0, ':')) [this would give output like this - 1900-01-01 11:45:00]
This code has been in place for years...and we stick the date on later from another column.
But recently, it's started to fail for some rows, with "The conversion of a varchar data type to a smalldatetime data type resulted in an out-of-range value".
My assumption is that new data being added in is junk. If I query for these values and just list them (rather than adding a column to convert them also) that's fine, of course. I've checked all the stuffed (but not yet converted - so 11:45 rather than 1145) output to see if it ISDATE(), and it is. There are no times with hours > 23 or minutes greater than 59 either.
If I add the CONVERT in, we see the error message. But here's the oddity, if I place all of the rows into a holding table, and retry the conversion, there is no error. It's this last bit that is puzzling me. Plus I can't see any errors in the hours data that would cause a conversion problem.
I've put the whole of this into a cursor to try to trap the error rows too, but all processes fine. Why would it fail if NOT in a cursor?
I am trying to calculate the time difference between the value in the row and the min value in the table. So say the min value in the table is 2014-05-29 14:44:17.713. (This is the start time of the test.) Now say the test ends at 2014-05-29 17:10:17.010. There are many rows recorded during that start and end time, for each row created a time stamp is created. I am trying to calculate the elapsed time and have it as a row in the results.
min(timestamp) - timestamp(value in row) = elapsed time for that test where Channel = '273'
Here is the table DDL
CREATE DATABASE SpecTest; USE SpecTest GO
CREATE TABLE [dbo].[Spec1]( [Spec1ID] [int] IDENTITY(1,1) NOT NULL, [Channel] [int] NOT NULL,
I need to query the count of an occurrence in a given period of time, so I created this query. But it does not give me any results.
SELECT TOP 1000 o.[ID] ,o.[TimeOfOrder] ,x.[StreeLine1] FROM [SC].[dbo].[bvc_Order] o FULL JOIN SC.dbo.xmlAddressRead x ON o.ID= x.id WHERE DATEDIFF(HOUR,o.[TimeOfOrder],(DATEADD(Hour, -48, GETDATE()))) < 48 GROUP BY x.[StreeLine1], o.ID, o.TimeOfOrder HAVING COUNT(x.[StreeLine1])>1
Then I change the query slightly and I ask it to show me the ones that are going to '599 Ships Landing Way' and it gives me 356 results! The Query doesn't crash, but it doesn't give me the results I need. What did I do incorrectly?
SELECT TOP 1000 o.[ID] ,o.[TimeOfOrder] ,x.[StreeLine1] FROM [SC].[dbo].[bvc_Order] o FULL JOIN SC.dbo.xmlAddressRead x ON o.ID= x.id WHERE DATEDIFF(HOUR,o.[TimeOfOrder],(DATEADD(Hour, -48, GETDATE()))) < 48 AND x.[StreeLine1]='599 Ships Landing Way'
I've got this issue with a query in SSIS. From a table in SQL Server I'm getting over 25000 different identifiers. These identifier are associated to many values in a table in  one Oracle Database. This is the schema that I have implemented for doing this.
The problem is that some days the identifiers can be over 45000, and at this point perform a loop for every one is not the best solution (It can take to much time to get the result). Previously I have performed another query where from the SQL statement.
I am creating and sending a unique row with all the values concatenated and then I have recover this unique string from an object and use it to create the query in the ODBC Source that invoke the table in Oracle: something like this: 'Select * from Oracle_table' + @string_values
with @string_values = 'where value in (........)'. It works good because the number of values is small enough to be used, like 250. But in this case I can not use this approach because the number is really big and obviously the DBA of Oracle is going to cancel the query.
So I wonder, how can I iterate over the object getting only a few number of values everytime, something like 300 or maximum 500, to avoid the cancellation of the query but at the same time doing the minimum number of loops.
I am producing a php report using SQL queries to show the SLA status of our calls. Each call has response, fix & completion targets. If any of these targets are breached, the whole SLA status is set as 'Breach'.
The results table should look like the one below:
CallRef.

Whereas I can pick the results for the first 6 columns from my Select query, the 'SLA Status' column requires the following calculation:
The problem is that my query is returning multiple entries for each stage of the call (see below), whereas I just want one entry for each call, with SLA status 'Breach' if any of the stages for the call were out of SLA.

Any help will be much much appreciated, this issue has been bothering me for some time now!!!
I have got an application developed on SQL7 which I have migrated to SQL2K. It handles authentication internally and therefore stores usernames & passwords in a local table. The passwords are stored encrypted utilizing a function called "encrypt" taking the password in clear-text and returning a varbinary. When a user logs on his password input is encrypted the same way and compared to the stored password. So far so good... Problem: On SQL2K the encrypt function returns a different result as it does on SQL7., which reults in authentication failures. Unfortunately I cannot find any documentation about the encrypt function e.g. in BOL. Furthermore I cannot ask the developer who introduced the function anymore.
Hi All, In SQL 2000, i need to Export Data,so that datashould be encrypted.When i try to import that in any database it should authenticate the user and should get decrypted.IZAT Possible.
Hi folks, I'm trying to encrypt a small token of data on my client c# application and have it decrypted by SQL on the server side, the problem is i cannot find articles on the subject. I don;t really want to get involved with certificates but base the system on a simple symmetric key that is shared by both parties.
I'm attempting to use the TRIPLE_DES algorithm on both sides and thus far have used the decryptbypassphrase on the server side with the data encrypted on the client side by .Net with no initialization vector setup.
If anyone can recommend any articles or have example (client and server side) code for this situation it would be greatly appreciated.
Does anyone know what my .net app guys need to share with me if encryption was done in the .net app but decryption needs to occur in certain sql queries? I read about master keys, certificates, symmeteric keys, algorithms etc but dont know how that stuff would carry over from the framework into sql. All I know is that the algorithm is AES_256, they must be adding authentication to the encryption and i know the hash algorithm, and symmetric keys are involved. Will they be sharing certain kinds of files with me that need to be registered in the db? Will I have to use CLR if I want the two worlds to come together?
hi, like, if i need to do delete some items with the id = 10000 then also need to update on the remaining items on the with the same idthen i will need to go through all the records to fetch the items with the same id right? so, is there something that i can use to hold those records so that i can do the delete and update just on those records and don't need to query twice? or is there a way to do that in one go ?thanks in advance!
I have four tables: Customer (CustomerId INT, CountyId INT), County (CountyId INT), Search(SearchId INT), and SearchCriteria (SearchCriteriaId INT, SearchId INT, CountyId INT, [others not related to this]).
I want to search Customer based off of the Search record, which could have multiple SearchCriteria records. However, if there aren't any SearchCriteria records with CountyId populated for a given Search, I want it to assume to get all Customer records, regardless of CountyId.
Right now, I'm doing it this way.
DECLARE @SearchId INT = 100 SELECT * FROM Customer WHERE CountyId IN ( SELECT CASE WHEN EXISTS(SELECT CountyId FROM SearchCriteria WHERE SearchId = @SearchId) THEN SearchCriteria.CountyId
[Code] .....
This works; it just seems cludgy. Is there a more elegant way to do this?
Hello. I currently have a website that has a table on one webpage. When a record is clicked, the primary key of that record is transfered in the query string to another page and fed into an sql statement. In this case its selecting a project on the first page, and displaying all the scripts for that project on another page. I also have an additional dropdownlist on the second page that i use to filter the scripts by an attribute called 'testdomain'. At present this works to an extent. When i click a project, i am navigated to the scripts page which is empty except for the dropdownlist. i then select a 'testdomain' from the dropdownlist and the page populates with scripts (formview) for the particular test domain. what i would like is for all the scripts to be displayed using the formview in the first instance when the user arrives at the second page. from there, they can then filter the scripts using the dropdownlist. My current SQL statement is as follows. SelectCommand="SELECT * FROM [TestScript] WHERE (([ProjectID] = @ProjectID) AND ([TestDomain] = @TestDomain))" So what is happening is when testdomain = a null value, it does not select any scripts. Is there a way i can achieve the behaivour of the page as i outlined above? Any help would be appreciated. Thanks, James.

Hi,I have a .net application and i added a code that encrypts data saved in database. However, there is already data in the fields that was entered before this change.I know need to check if the values in those fields are encrypted and if not i need to encrypt them.How can I perform such a check and update the relevant data?I use TrippleDES in .net to encrypt/decrypt the data.Thanks
Hi, I would like to know that how can I encrypt a stored procedure, so that it can not be decrypt by me or not by any one ? I have tried using the SQL encrypt,but there is a decrypt command which decrypt the same. I do not want any one to decrypt without a password or encrypt the stored procedure so that it can never be decrypted. Thanking you, Regards..Jay
