Hi,
I am in a situation where our developer is on leave (annual leave for a month), and I have to add a control to my website, which is in aspx apges.
To start with i have created a table in my SQL database. this table has records with one-liners from various movies, and the movie title. The tabel have 3 columns, i.e. ID, Liners, MTitle.
So i want to get random records on the page when ever its refreshed. I am totally non-coder/programmer guy.
I have got a SQL statement from the internet " SELECT TOP 1 * FROM <table name> ORDER By NEWID() "
So would anyone please help me out with it, as is it correct, how can i apply in the aspx pages.
Hello. I need to select a random record from TABLE. It might look easy with using RAND() function, but the tricky part is that ID's which are the PRIMARY KEY, were assigned as a random number. So right now ID's in that TABLE look some thing like that: -18745, 45809, 129, -5890023, 487910943, -209, etc... If any one have any ideas please respond. Thanks in advance.
I need to write a select statement where I need to select the record randomely. Is there any function to do that? What's the best way to do that? Please help...
hello members i want to no that weathere there is any procedure to select come random records from the database for eg i want to select 10 students out of 100 randomly is there any query for this in SQL server 200
I am using this select statement to radomly display a recordSelectCommand="SELECT TOP 1 * FROM [TBL_Example] ORDER BY NEWID()I need to, however, flag this record, to determine if it has already been previously randomly selected, and won't take part in future random selections.I will need to add a where clause to the above, but what I am unsure of is what I should do for the insert statement. I guess I could figure this out on my own as well if I could determine a means to prgramatically store my PK from the above record in session.Any ideas?
I'm familiar with querying for a random record, however I can't seem to do it using a parameter driven TOP value.
Here's what I've tried in a stored procedure: ( @Count int = 1 ) declare @sql varchar(1000) set @sql = 'SELECT DISTINCT TOP ' + convert(varchar, @Count) + ' * FROM RandomisedView'
The view I am using looks like:
SELECT TOP 100 PERCENT dbo.TableName.* ORDER BY NEWID()
The stored procedure does not seem to cause the View to reorder the records.
I need to be able to select X random records. Any help would be appriciated.
I need to generate a random whole number between 0 and 999 to add toadd to every record in a table. The number needs to be different foreach record in the table.How would I do this all within TSQL?
Hi,I need to extract randomly 5 records from the table "Questions". Now I useSELECT TOP 5 FROM Questions ORDERBY NEWID()And it works. The problem is that I need an additional thing: if SQLextracts record with ID=4, then it should not extract record with ID=9,because they are similar. I mean, I'd like something to tell SQL that if itextracts some questions, then it SHOULD NOT extract other ones.How can I do it?Thanks!Luke
Hi I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Hi,I have a form that should show 2 pictures based on table entries.I want those 2 pictures to be randomly selected based on a database table. So, my table has all the entries, and I want to pull out a random entry that has been approved to display it.Can someone help me with the sql query?I can do SELECT VoteId FROM tblVotes WHERE Approved=True..But how do I make selection a random one that changes every time the user gets another entry?
Is that possible to restrict inserting the record if record already exist in the table.
Scenario: query should be
We are inserting a bulk information of data, it should not insert the row if it already exist in the table. excluding that it should insert the other rows.
Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray
Anyone have any suggestions on creating a query that will randomly select records from a table, but not use those records again. I have some code that does it, but it uses the same fields over again, and also throws in some blank records that I did not specify in the query. I am creating a test engine that has to randomly ask questions.
hi I have a field call: password, I want to generates some random chars as default password for users (so user got something to login, and update later).
Current Solution I have: I made myself a trigger and it does generate password on insert, but the problem with that is I have to allow NULL on that field. I don't want NULL to be allowed, and if I don't allow null... sql server won't allow me to insert a record (when leaving password field empty).
Reason i don't wanna allow NULL on that field, is because there may be more applicaions using the same field from the same database. Just in case if the other developer gets sloopy, I don't want other application(s) allow user put to enter a null or leave it blank on my password field.
My question is: 1) can I put a function or some sort at the "Default" field under "Design Table", if so...how? 2) any suggestions for a better implementation? 3) if (1) doesn't work, what other options would you suggest other then the current trigger i'm using?
We have a SQL Server 2008R2 system that has heavy usage to one specific table. I have tuned basically all I can as far as making sure SQL Statements are using good indexes. From time to time a group of folks will log into Mgt Studio and run SQL Statements like this, leave the query open and once in a while it will cause blocking to other SQL running our online system
The query is like this: select ID,* from tablename with (nolock) where ID like 'MSPRYy%'
The results come back within less than 1 second. However, they leave this window open which is what causes this to be a HEAD BLOCKER and blocks other SQL Statements from running.
I am using Sql Server 2008 R2.I have a existing query that basically says
Select Top 50 Subscriber_ID, Member_Name, Group_ID from my_table order by rand(checksum(newid()))
However the client now wants to have at least two from each group_id. There are 17 different groups. When I run this as is I get about six of the 17 groups in the results. How can I change this to get at least two results from each group_id?
I'm using ASP and SQL Serv 2000. What I need to get from 2 tables (company & customers) is random 10 customers from random 20 comp. Anyone got an idea how to do this??? I've spent 2 days trying to get stored proc. or T-SQL to work, but nothing good came out of it. I can get 1 comp and 10 cust, but not a grouped list of 20 comp. w/ 10 cust. each.
I'm grappling with this issue which I thought was basic VB programming; I'm trying to insert a random number (between 100 and 999) into a SQL table column (=Status_ID). This is input as part of a user submitting helpdesk requests via a APS.Net Web Form. The 'Status_ID' field is obviously not visible to the user but will help reference this Helpdesk request on the database.Here is the code:Protected Sub submitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitButton.Click If Page.IsValid Then ' Define data objects Dim conn As SqlConnection Dim comm As SqlCommand ' Read the connection string from web.config Dim connectionString As String = _ ConfigurationManager.ConnectionStrings("ITNet_Students").ConnectionString ' Initialize connection conn = New SqlConnection(connectionString) ' Create command comm = New SqlCommand( _ "INSERT INTO HelpDesk (First_Name, Last_Name, StudentID, PersonalEmail," & _ "CategoryID, SubjectID, Description, StatusID) " & _ "VALUES (@First_Name, @Last_Name, @StudentID, @PersonalEmail, " & _ "@CategoryID, @SubjectID, @Description, @StatusID)", conn) ' Use randomize Randomize() Dim randomvalue As Integer ' Generate random value between 999 and 100. randomvalue = Int((900 * Rnd()) + 100) ' Add command parameters comm.Parameters.Add("@First_Name", System.Data.SqlDbType.NVarChar, 50) comm.Parameters("@First_Name").Value = fnameTextBox.Text . . . comm.Parameters.Add("@StatusID", System.Data.SqlDbType.Int) comm.Parameters("@StatusID").Value = randomvalue 'Enclose database code in Try-Catch-Finally Try ' Open connection conn.Open() ' Execute the command comm.ExecuteNonQuery() ' Reload page if the query executed successfully Response.Redirect("HelpDesk.aspx") Catch ' Display error message dbErrorMessage.Text = _ "Error submitting the help desk request! Please try again later, and/or change the entered data!" Finally 'close connection conn.Close() End Try End If End Sub----------------------------------------------------------------------------------------------------------------------I keep getting the error message under 'Catch' and the page 'HelpDesk.aspx' is not reloading; the 'comm.ExecuteNonQuery()' is not executing.Can anyone spot any inconsistencies in the declaration of the 'randomvalue' variable?P.S: this code works fine if you replace 'randomvalue' with any integer in 'comm.Parameters("@StatusID").Value = randomvalue'
I'm trying to write a function that will retrieve the last backup date/time of a particular database on a remote server (i.e. by querying msdb.dbo.backupset). Unfortunately, you can't use sp_executesql in a function, so I can't figure out a way to pass the server name to the query and still be able to return the datetime value back to the calling TSQL code (so that rules out using EXEC().
Im from Russia, sorry if my english is not very good.
Here's the case:
1)------------------------------- I made a DTS-package in sql2000 that transfers the [sql table] into [dbf file] via jet4. First i create (in delphi) the empty dbf with the same name and columns same as in sql table. Second, I run my DTS with variables - source and destination table names
In DTS there is source, destination and transformation . After I send the Variables(table names) , the transformation "arrow" needs to be "refreshed" to make column names in both tables correspond each other. For that in transformation I chose ActiveXScript Mode and wright VB Script:
' Copy each source column to the destination column Function Main()
dim i
For i = 1 To DTSSource.Count DTSDestination(i) = DTSSource(i) next
Main = DTSTransformStat_OK End Function
And it works
2)------------------------------ I want to do same thing in sql2005 SSIS but don't figure out how... I managed to make a package that recieves (in variables) table names and runs correctly. But after I change those variable names into any other it crashes - Description: "component "OLE DB Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
Of cource this happens 'cause I didn't "refresh" the transformatoin (and maybe also source and dest), but I don't know how.
I'm trying to add random dates to date column in existing table, but these need to be week days (Mon-Fri).I'm a beginner in TSQL, worked with MS Access many years - in Access I used to do something a bit different:
DateAdd("d",(Int((5*Rnd([ID]))+1)),#31/08/2015#) Table had ID, I gave a date it would start from (31/08/2015) and then range of ID to apply new date: UPDATE table1 SET table1 .date = DateAdd("d",(Int((5*Rnd([ID]))+1)),#31/08/2015#) WHERE (((table1 .ID) Between 1 And 5456));
This was applying random dates in range of 31/08/2015 + 5 days, so I could give a starting date of Sunday to get random dates populated over given IDs from Monday to Friday.Now, how can I do it in TSQL?I have a table with ID and dates column. I would like to apply new random dates from some range, but making sure they will be week days.
My overarching goal is to generate sets of random Symptom records for each Enrollee in a drug study, so that for each cycle (period of time), the code will insert a random number of random records for each enrollee.
I'm trying to return a number of random records from a table, but inside a table-valued function... (which could be my problem).
CREATE FUNCTION dbo.ufn_GetTopSymptoms ( @enrollID INT , @CTCVersion VARCHAR(20) , @NumRecords INT ) RETURNS TABLE
[Code] ....
But that ORDER BY NEWID() clause is illegal apparently, because here's the error it throws:
Msg 443, Level 16, State 1, Procedure ufn_GetTopSymptoms, Line 13 Invalid use of a side-effecting operator 'newid' within a function.
I was hoping I could return a set of enrollmentIDs and then use CROSS APPLY to generate a random set of records for each enrollmentID... is this not possible with APPLY? I was trying to avoid using a cursor...
The idea is basically to create all the Symptom records for all the patients in treatment cycle at once by using Enrollee OUTER APPLY dbo.ufn_GetTopSymtoms(dbo.Enrollment.EnrolleeID)
but that's clearly not working. Is there a way to do this without resorting to a cursor?
CREATE TABLE [Sales].[Test_inmem] ( [c1] [int] NOT NULL, [c2] [nvarchar](20) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [ModifiedDate] [datetime2](7) NOT NULL CONSTRAINT [IMDF_Test_ModifiedDate] DEFAULT (sysdatetime()),
[Code] ....
I have to generate 1000000 random records into it. I tried various ways to insert records, but not being a developer could not do it. I hope to make the C1 as a serial number, C2 can be anything, C3 I want to be the timestamp.
Consider the below code: I am trying to find a way so that my select statement (which will actually be used to insert records) can randomly place values in the Source and Type columns that it selects from a list which in this case is records in a table variable. I dont really want to perform the insert inside a loop since the production version will work with millions of records. Anyone have any suggestions of how to change the subqueries that constitute these columns so that they are randomized?
