I am new to SQL Server (coming from Oracle background) and have a large table I need to loop thru and assign a number 1 thru 5 on each record.
below is an example of how I would do it in Oracle.
declare
num number := 1;
cursor c_rec is SELECT rowid, t.* FROM temp t order by t.column;
begin
for d_rec in c_rec
loop
update temp set column = to_char(num)

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.
I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.
SELECT
S.Id
, RMA
, PinSerial
, L4Serial
, L4Model

Good day!
I have the qry, which is suppose to assigned records to active user (almost 15 users) equal, but it doesn’t- sometime it assigned more to some users and less to others. How could I modify my qry to make sure it assigns the records equals to each user? Please, see the qry below. I will appreciate any help

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?
Thanks in advance.

How can I update my users table and set the password field to a random number or string.

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.

Will appreciate help on this

View 21 Replies View RelatedIn 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.

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 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.
thoughts ?
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

I have a table with 3 columns , let say (PatientIDÂ int, AppointmentDate date, PatientName varchar(30))

 2                01/10/2012         Sam
 3                02/15/2012         John
I need output in below way..
PatientID       AppointmentDate     PatientName
 1                01/01/2012         Tom   (actual patient record)
 null             01/10/2012         Tom
 null             02/15/2012         Tom
 null             01/01/2012         Sam

  null             01/01/2012         John
 null             01/10/2012         John
 3                02/15/2012         John    (actual patient record)
I need t-sql to get above output. Basically the appointment dates are repeatedly assigned to each patient but only difference is patientid will be not null for actual patient record.

I'm trying to find it difficult to use recursice CTEs or better solution for a special request below. There are two tables 1) @sizes serves as a lookup or reference for right drive and 2) @test is sample data with different sizes. Assume that I want to evenly distribute the drive letters from table1 to table2 by checking the size available.
E.g.: for the first record in @test; id = 1 where the size is 50 and it fits in Y: drive -- left over space in Y: = 50
id=2, size 2.5, space available from left over = 50 - 2.5 = 47.5 which again fits into Y:
id = 3, size 51, cannot in fit in Y: drive as there is enough space in Y: to allocate (51 > 47.5)
so pick the next drive check on availability again
DECLARE @sizes TABLE (id TINYINT, size DECIMAL(5,2), drive VARCHAR(3))
INSERT INTO @Sizes
SELECT 1,100.00,'Y:'
UNION ALL
SELECT 2,80.85,'Z:'
[Code] ....
-- My output should look like
col1 , val ,  path
AÂ Â Â Â Â Â Â Â Â 50 Â Â Â Y:
B Â Â Â Â Â 2.5 Â Â Y:
C Â Â Â Â Â 51 Â Â Z:
D Â Â Â Â Â 2.6 Â Â Y:

I am using Sql Server 2008 R2.I have a existing query that basically says
Select Top 50 Subscriber_ID, Â 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?
Got this query and I need the following result;
declare @NumberToCompareTo int
set @NumberToCompareTo = 8
declare @table table
(
number int
)
insert into @tableÂ
select 4
[Code] ....
The query selects 4 and 5 of course. Now what I'm looking for is to retrieve the number less or equal to @NumberToCompareTo, I mean the most immediate less number than the parameter. So in this case 5
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.
