I have a table which has two column like following table and I don't know how can I update theses two column with identity numbers but just the fields which are equal 111.
my example table:
numez numhx
111 111
111 111
0 111
111 0
111 0
and my results should be:
numez numhx
1 2
3 4
0 5
6 0
7 0
I have a question in SQL server. For example I have a table which has two column like following table and I don't know how can I update theses two column with identity numbers but just the fields which are equal 111.

111 111
0 111

I have the following data in a table:
Account SEQ
12345 1
12345 2
12345 4
12345 5
12345 7
I need to fix the SEQ field so that no gaps exist, like this:
Account SEQ
12345 1
12345 2
12345 3
12345 4
12345 5
Is there a way to do this with T-SQL?
Is is possible to Generate sequence numbers in a Query result in an SQL select Statement
like
Select sno,employee_name from empmaster
sno being a number with auto increments(this Field will not be in a Table).
I do not want to use Identity .....
This is Just to Provide a Serial Number to the Query Output...
thus the Out put should be something like
sno employeename
--- ------------------
1 abc

hi all
I am stuck with something that seems easy but im obviously clueless as how to execute the idea.
I have a custom table that houses invoices on the details level. So for example i have:
InvcNo
00000001
00000001
00000001
00000002
00000002
00000003
and so forth
What I am wanting to do in another column is keep track of the sequence number for each distinct invoice like:
SeqNo
1
2
3
1
2
1
I am working in a stored proc and i cant get past adding the numbers up at each line as a whole and not reseting when the next invoice number is present. Any help would be so greatly appreciated.
Thanks
Hi,
What transformations can be used to generate sequence numbers in a data flow?
I have a procedure which updates a sequence number in a table such as the one below.
Seq Sequence_Id
------ ------------------
NextNum 1
This is the procedure ...
create procedure DBO.MIG_SYS_NEXTVAL(@sequence varchar(10), @sequence_id int)
as
begin
update mig_sys_sequences
set
@sequence_id = sequence_id = sequence_id + 1
where
seq = 'CSN'
return(@sequence_id)
end
The purpose of this is to generate a sequential number each time the procedure is called. This number would then be used in a number of different tables to allocate a unique id so that the id is unique across the different tables.
1). What is the most efficient way of allocating these unique ids? The tables that I plan to update will already be populated with data.
2). How would I call the above procedure from an UPDATE statement?
Many thanks,
Fred
If Exists ( Select c.name from sys.columns c where object_id = object_id('HH835HP') and C.name = 'ID_1' )
Begin
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;
End;
Obviously... The stuff inside the IF is wrong syntax...I mean
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;
I have a Contact table where I enter a "Parent" (Mother or Father) with IsSubscriber = 1. I also enter all of their children in this same table, with IsDependent = 1.
I then have a Relationship table that relates each child to the appropriate parent record in the Contact table.
I need to assign a sequence number to each child ONLY if they were a multiple birth (twins, triplets, etc.; all have the same DOB). I've been successful at writing a query using ROW_NUMBER(), but it includes the single births (no other child of the same parent has the same DOB).
Stripped down version of Tables and Data and my failed attempt to write a query to do what I want:
IF OBJECT_ID('TempDB..#Contact','U') IS NOT NULL
DROP TABLE #Contact
CREATE TABLE #Contact (
ContactId INT IDENTITY(1,1) PRIMARY KEY CLUSTERED

This is as close as I can seem to get.
The following works just fine. The table tmpMHPCLMDET does have a column ADMTDT ( varchar(8) ).
While I am adding the sequence of numbers I like it to be sorted based on ADMTDT column.
What that means is the row with the earliest ( smallest ) ADMTDT will get 1 and the next 2 and so on.
Declare @ID int
If Exists ( Select c.name from sys.columns c where object_id = object_id('tmpMHPCLMDET') and C.name = 'ServiceLineID' )
Begin
--Adding a sequence of numbers to the ServiceLineID column.
SET @id = 0
UPDATE tmpMHPCLMDET
SET @id = ServiceLineID = @id + 1;
End;
In a t-sql 2012 sql update script listed below, it only works for a few records since the value of TST.dbo.LockCombination.seq only contains the value of 1 in most cases. Basically for every join listed below, there should be 5 records where each record has a distinct seq value of 1, 2, 3, 4, and 5. Thus my goal is to determine how to add the missing rows to the TST.dbo.LockCombination where there are no rows for seq values of between 2 to 5. I would like to know how to insert the missing rows and then do the following update statement. Thus can you show me the sql on how to add the rows for at least one of the missing sequence numbers?
UPDATE LKC
SET LKC.combo = lockCombo2
FROM [LockerPopulation] A
JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
JOIN TST.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number

Hi,
I would like to know different possible ways in appending extra values like new uniqueidentifiers, sequence numbers, random number. Can you please tell what type of data flow components helps us ?
I have a database that has entries that I want sorted by date order. Each entry has an auto ID number allocated (primary key auto sequencing), which I want to change to reflect the sorting (so the first date has the first auto ID number and so on).I've gone into the database and sorted the entries as I want them. Then I've gone into Design View to delete and restablish the primary key autosequence. However, it is not keeping the date order in the database (ie entry ID 3140 date is 12/06/2015, but 3141 is 02/02/2012). How do I get it to maintain the order?

View 3 Replies View RelatedHi all,
In my project i will have the data in a collection of objects, I need to update series of tables with foreign key relations
Right now my code looks like this
foreach(object obj in Objects){
int accountId=Account.Insert(obj.accountOpenDate,obj.accountName);//this will update the accounts table and returns account id which is a Identity column in Acccounts table
int DebtId=Debt.Insert(accountd,obj.debtamount,obj.debtbalance); this will update the Debts table and returns DebtId
///series of tables like above but all the relevant data comes from obj and in the Insert Methods i am using stored procedures to Insert the data into table
}
The no of objects varies from 1000 to 1 milliion,, with this approach its taking more time to update all the data. Please let me know if any alternative procedure to handle this kind of scenario.
Thanks

Hello,
One more question about this Custom Calendar table I'm creating. I have a column called "IsWorkdays" which indicates if the day represented by a row is a workday or not. For our purposes, I also need to create a row that accumulates those numbers by month. So, if it is the 3rd workday of the month, this column would have a 3. This is beyond my current T-SQL ability. Does anyone know how to do this?
Thanks a lot,
Andy

How does one pass into a Stored Procedure an array of numbers to be used in an IN clause? If I pass "1,2" in a VARCHAR, the stored procedure sees only the first number (1 in this case).
I'm using VB and ADO.NET, but I don't know how to set up the stored procedure for an array. Is there a parsing function to do this?
CREATE PROCEDURE TestInClause( @TeamList VARCHAR)ASSELECT Name FROM Teams WHERE TeamID IN (@TeamList); /* sees only 1st number */GO
I am currently undertaking a review of the primary keys in a SQL Server2000 database with a view to improving performance of queries.I have heard that, in the case of compound primary keys, it isimportant to select the correct order for the columns within the key.For instance, imagine a table called OrderLine which has primary keycolumns as follows-LedgerOrderNumberOrderLineNumberThe theory I have heard is that columns with the most distinct valuesshould come first. In this case, Ledger is likely to have a maximum of6 distinct values, OrderNumber a maximum of 10 million and OrderLine upto 99. Based on this supposition I believe the best order would be-OrderNumberOrderLineNumberLedgerI have performed a few rudimentary tests that appear to bear this out.I was wondering if anyone else has tried something similar and if sowhat was the result?Thanks,Ross

Is there a method to construct select statement on a table without using column names, based on column numbers.
I want to create a function which returns the contents columns 1 and 2, given just the name of the table.
An Execute statement, after retrieving the column names with Column_Name is not useful as they are not permitted in functions.

I have a large table with many columns that have rows with N/A or null values, which are gotten from a bulk insert.
In order to format the data properly, we need to convert the data from N/A or null to 0, as the original values come from the supplier.
In my code the best way to achieve this is running multiple queries as
update csv_testing set testing5 = 0 where testing5 like'%N/A%'
update csv_testing set testing6 = 0 where testing6 like'%N/A%'
update csv_testing set testing7 = 0 where testing7 like'%N/A%'
update csv_testing set testing9 = 0 where testing9 like'%N/A%'
etc for about 12 columns
is there a better way of doing this ?

Hi Folks,
Is there any way to add a derived column into the where clause.
Example:
Select Name, Date, Procedure#,

From Procs
Where Class = 'Y'
Thanks,
Ray
I have a checksum calculation as a persisted, indexed computed column on a temporary table that I used to compare against original records to detect changes.
It seems that the update/ insert statements in my procs get out of sync on larger tables (500,000 rows +) with the checksum calculations. The only thing I can think of is that the column calculations are performed asynchronously in relation to the updates/ inserts. This is a problem for me.
Is my assumption correct? If it is, how can I adjust for this, i.e., force the computations to be performed synchronously or wait for the computations to complete before running comparisons?

I am attempting to write a conversion of our product for Compact Edition; we already provide it based on SQL Server. The database interface uses ADO through a Python-win32com adaptor, and has worked fine so far. (Note: *not* ADO.net, just plain old COM)
Now, a curious thing happens. When inserting new data through a Recordset, everything works fine - except for columns defined as bigint. There are no exceptions thrown, but when you read the columns back they contain nothing but zeroes. Do the same to any other column type - I've tried integer, numeric, float, nvarchar and ntext so far, and they all seem to work just fine. It does not seem to be conversion-related either, since I've tested the exact same data to various column types. And using bigint on regular SQL Server works just fine.
The code involved is quite unspectacular, and simply switching the column types to integer would solve the immediate problem, but causes potential future issues since we normally store internal IDs in bigint columns, and the values may grow quite large.
