I have an 'ID' column. I'm up to about ID number 40000, but not all are in use, so ID 4354 might not be in any row. I want a list of all numbers which aren't in use. I want to write something like this:
select [numbers from 0 to 40000] where <number> not in (select distinct id from mytable)
My problem is one of my query is returing party_codes . now i also want a column which returns serial numbers along with it . the serial numbers are not stored anywhere. they should be autogenerated. My query is combining two different databases and its using union in it so i can not use count in it . Is there any other way i can acheive . for eg Now my query output is party_code ---------- R06048 R06600 R06791 (3 row(s) affected) I want it like party_code serial number ---------- ------------- R06048 1 R06600 2 R06791 3 (3 row(s) affected) The serial number column should be auto generated in the select statement it self Is there any system rowid i can use . Please suggest
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'
I have a database of details of users that visit my site. Among other things, it saves the ipaddress and the date/time of the visit. I would like to be able to determine the unique visitors (by ipaddress) that i have on any given day. The problem though is that the data is saved as a date and a time, thus when I try and determine the unique visitors, since they are all a different time, MSSQL thinks they are all unique visitors. Any ideas how I can get around this without acctually modifying the data in the underlying table?
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?

I am trying to insert a unique code, like a voucher code, into a table in MSSQL, 10 numbers (0-9) which obviously needs to be unique.
I can code this in ASP, but I think the process could be a bit long winded, i.e. create a key - run a stored procedure to see if it is free if not loop and check again. Surely there would be a way to do this in a stored procedure in one?
So the code would look like 3928492834.
1. Generate Key in SQL 2. Check if not used in column 'kcode' if it is, regenerate and check again.
Any advice would be greatly appreciated, I know how to do this in ASP but bit of a SQL newbie!
Is there any way to auto generate the unique primary key when inserting data in MS SQL? there is a way to create the increasing integer as primary key, but is there any ways other than that?
I'm working on a final project for school. It is a warehouse application. For this application I will need to generate a barcode. I have read some articles online and found out that I could use the code 39 barcode font.
I just don't fully understand how to generate the unique barcode. Could someone please help me? I also would like to store the barcodes in a sql server table. Could I use reports to print the barcode?
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.
My team is starting to implement error handling in our sprocs. One question we have is whether or not to use unique error numbers for custom errors (ie Errors we throw after doing some sort of validity check, not SQL Server errors). For example, we might check the value of a parameter and then throw an error that says "Parameter State_Date must be less than today, please retry".
We are using SQL Server 2012 and will be using the THROW statement, not RAISERROR, so we don't HAVE to put the numbers in sys.messages. Also, we are going to log the errors in a table, along with the error message, sproc name, line number, etc.
Is it useful to maintain a custom list of error numbers and messages? Or is it just as useful to use one standard error number and add a custom error message (which we can then search for in our code, or use the sproc name & line number we logged)? And if it is worth maintaining a list of numbers plus messages, should we go ahead and put them in sys.messages?
I have a question about adding a unique key column to an existing table.
what i trying to do is that: I have already created a table, now i wanna add a ID column to this table, and generate the values for ID column from 1 to the existing row number. How can I get this done?
Requirements • ALPHANUMERIC FORMAT – > AA00AA00………..ZZ99ZZ99 Last 8 bytes will alternate between 2 byte alpha/2 byte numeric • Generate from Alphabets – A through Z Numbers -0 to 9 • Generate Unique Sequence (No Duplicates). • Must Eliminate letters I and O
Output Expected • AA00AA00………..ZZ99ZZ99 • Using 24 alphabets & 10 digits , 24*24*10*10*24*24 = 3 317 760 000 records
Below is my Sql Function -
CREATE function [dbo].[SequenceComplexNEW] ( @Id BIGINT ) Returns char(8)
I have a report with a column which contains either a string such as "N/A" or a number such as 12. A user exports the report to Excel. In Excel the numbers are formatted as text.
I already tried to set the value as CDbl which returns error for the cells containing a string.
The requirement is to export the column to Excel with the numbers formatted as numbers and the strings such as "N/A' in the same column as string.
Why does M$ Query Analyzer display all numbers as positive, no matterwhether they are truly positive or negative ?I am having to cast each column to varchar to find out if there areany negative numbers being hidden from me :(I tried checking Tools/Options/Connections/Use Regional Settings bothon and off, stopping and restarting M$ Query Analyer in betwixt, butno improvement.Am I missing some other option somewhere ?
I have a table with a column ID of ContentID. The ID in that column is all NULLs. I need a way to change those nulls to a number. It does not matter what type of number it is as long as they are different. Can someone point me somewhere with a piece of T-SQL that I could use to do that. There are over 24000 rows so cursor change will not be very efficient.

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.
What's the difference in the effect of the followings: CREATE UNIQUE NONCLUSTERED INDEX and ALTER TABLE dbo.titles ADD CONSTRAINT titleind UNIQUE NONCLUSTERED
I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?
Hi everyone, I need urgent help to resolve this issue... As far as the performance goes which one is better.. Unique Index(col1, col2) OR Unique constraint(col1, col2) ? Unique constraint automatically adds a unique index and unique index takes care of uniqueness then whats the use of unique constraint ?
BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?
hi team, .Can i create umique constraint with out unique index.when i am creating a unique constraint sql creates a unique index (default) can i have only unique constraint ?
