How to create random number for the value in other colum. Please help and urgent
I have a table with 4 column ( ID, Ori_Quantity, Rand_Quantity, Location)
If Ori_quantity < 5000 then Rand_quanty as qty = I want Random number within 100 Else If Ori_quantity = 0 or < 10 then Rand_quanty as qty = I want Random number within 7 End if
From tblname where Location = 'DAS'
I have around 2500 field. So when I run the query I expect the result should be like below
I need to generate a random 10 digit alphanumeric string that is also unique within a table. My application will be calling a stored procedure to insert this number into the table. This number will be associated with a id from another table. Is it better to generate the random number within sql (and perform the lookup at the same time), then just pass the number back to the calling application ?
If the calling application generates the number, it will also need to make a call to check if its unique. So im thinking it would be best to simply have sql generate this random number, check the number against the table and then insert the new record.
I've used some info on here to generate random dates within a given range and also random times - independently they work fine, but I can't seem to join them into a single field of datetime. I'm not sure why. The following snippet works fine as two independent fields:
select CAST(CAST(ABS(CHECKSUM(NEWID()))%(780)+(33968) AS DATETIME) as DATE) as theDate, CAST(CAST(DATEADD(milliSECOND,ABS(CHECKSUM(NEWID()))%86400000 ,'00:00') AS TIME) as varchar(50)) as theTimeBut when I try to make it a single datetime field:
select CAST(cast(cast(CAST(ABS(CHECKSUM(NEWID()))%(780)+(33968) AS DATETIME) as date) as varchar(50)) + ' ' + cast(CAST(CAST(DATEADD(milliSECOND,ABS(CHECKSUM(NEWID()))%86400000 ,'00:00') AS TIME) as varchar(50)) as varchar(50)) as datetime)
Which returns with: Conversion failed when converting date and/or time from character string.
So what I am really looking for is a way to join those two values into a single datetime field... Or failing that that how to generate random dates within a range including random times...
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.
What I want to achieve is to get values from period1 till period04 and used the lasted value to code the value of accoutperiod, if value is from period1 then code it as 01, period2 as 02, period03 as 03 and period04 as 04. So the output should be like this
Dear All, I have some problems with the assignment from my professor.
Suppose there are two tables storing first names and last names, one table with column of first name and gender, the other with last name.
how to write stored procedures to get a random first name + random last name for Males or Female. like you got a list of all M & F first name and last name, then you try to match first name with any other last name (I believe this is random).
and the task is to write a script so each time when a female or male full name is need, it will return a random name for the requested gender.
I am totally struck and no idea how to deal with it, in fact I am just a beginning in SQL server, and I know there is a stored procedure to generate random number, however, I can't see the use of it here,,,,:eek:
Could anyone help me out ? thanks very much !!!:beer:
I need to generate random strings each of length 7 characters and update it in a table that contains employee data.For example. There is table called as Employee. It has Id, FirstName, LastName & Email as the columns. I need to mask the real names. So i have to generate random characters between a-z unique for individual records and update it in the table.
I went through some websites for generating random characters. These provide a 7 or 8 character random letters. URL...But i do need to update 2 columns of an entire table with random characters.
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?
The result of the query I'd like should look something like this
1 2 5 7 8
So basically I'd like to leave record 3 and 4 out because they fall within 24 hours of record 2 and I'd like to leave record 6 out because it falls within 24 hours of record 5.I'd tried working with a CTE and set a dateadd(d, 1, recorddate), join it on itself and use a between From / To filter on the join but that didn't work. I don't think NTILE will work with this?
I have the following SQL which i want to convert to a stored procedure having dynamic SQL to generate column numbers (1 to 52) for Sale_Week. Also, I want to call this stored procedure from Excel using VBA, passing 2 parameters to stored procedure in SQL Server e.g,
DECLARE @KPI nvarchar(MAX) = 'Sales Value with Innovation' DECLARE @Country nvarchar(MAX) = 'UK'
I want to grab the resultant pivoted table back into excel. how to do it?
USE [Database_ABC] GO
DECLARE @KPI nvarchar(MAX) = 'Sales Value with Innovation' DECLARE @Country nvarchar(MAX) = 'UK'
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?
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.
I need to create a script that adds an incrementing suffix to two columns, but restarts based on the value of another column. I found a similar question in the SQL Server 2000 forum, but it doesn't quite fit and also I'm working with SQL Server 2008 R2. The code below both creates a table with test data and tries to carry out the task. If you run this, you will see that the VISITNUM column has a value of UNS in row 4, UNS.1 in row 5 and UNS.2 in row 6. In row 7 it's V200, then in rows 8 and 9 it's UNS.3 for both. The same suffix gets applied to the VISIT column, but of course if I can solve this for VISITNUM then adding the suffix to VIST as well will be easy.
What I need is for row 8 to have UNS and row 9 to have UNS.1. In other words, any time the VISITNUM is UNS several times in a row, I need to add that ".X" suffix, but if a row has something other than UNS, I need to start over again the next time it's UNS again.
I need to update an integer column in my table with a random number. Here's what I've done so far (with the table name and column names changed):
UPDATE dbo.MyTable SET Column1 = RAND() * 1000000
My question is, how come the values in my column all have the same value? I thought the RAND function gives out a random number? How can I update my table to generate random numbers?
i have an application that uses a table for login access, for security reason i need to get a random numbers in this table daily. table consist of just two columns, userid and password. This table will be printed out on the web for users to get valid username and pw daily. I m thinking about a job or dts package that will run once daily with a sql script to generate random number (referable 5 digit-letters and numbers), delete the table and re-create the table with same set column names and insert the random values in username and pw column. Will appreciate help on this
In a Name table, I need to generate unique 6 digit random numbers in a field called UniqueID for all records that have the ID field populated. I will need to run this script periodically. It is critical that any prevoiusly assigned UniqueIDs do not change and only fields that have an empty UniqueID field are updated. I need to preserve the historical mapping of the existing IDs to the ongoing assignment of UniqueIDs.
I have heard that high numbers of VLF's aren't good. It can impact performance and can delay recovery time, so I wanted to test that.
I created 2 DBs with 100MB datafile and 50MB logfile.
TestDB log file had 100MB autogrowth TestDB2 log file had 1% growth.
I inserted 1048576 records, took the backup
Ran DBCC loginfo and TestDB had 40 VLFs and TestDB2 had 165 VLFs
But when I restored both DBs, this is what I got.
TestDB: RESTORE DATABASE successfully processed 42258 pages in 4.420 seconds (74.691 MB/sec). SQL Server Execution times: CPU Time = 125ms, elapsed time = 8323 ms.
TestDB2: RESTORE DATABASE successfully processed 42257 pages in 3.943 seconds (83.724 MB/sec). SQL Server Execution Times: CPU time = 109 ms, elapsed time = 8314 ms.
Question is: Where is the difference? How TestDB which has 40 VLFs are better than TestDB22 which has 165 VLFs.
ID  Item           RandomNumber ------------------------------------------- 1   JEANS                   1234567 2   SHIRT                 72813550 3   HOOD                           Null 4   TROUSER             72191839 5   BLAZER                            0
I want to perform a query so that SQL should look for RandomNumber Values and set a Unique Random Number Where RandomNumber Value is Null or 0.So I have got a solution as one of the MSDN Member shared the below query
select id,item,RandomNumber=Case when RandomNumber=0 then (select floor(rand()*100000000-1)) when RandomNumber is null then (select floor(rand()*100000000-1)) else RandomNumber end from tblProducts
So, can you all confirm me, that performing this query ensures that if a Value is assigned to one of the Item in RandomNumber Column, that value will not be assignend to any other Item in RandoNumberColumn.
Hey Guys, I have a quick stored procedure question for you. I created a procedure that returns a randomly generated number.
I know there is a built in Rand() function but I need to be able to specify the range. Anyways, it€™s returning multiple numbers (1 for each row in the tempTable) But I just want one number returned. I tried using MAX( ) but that€™s not a good way of doing it.
My question is, how do I return just one record or number?
Thanks Fellas,
Chris
