I have a db to manage the creation of invoice number designed for a web application.
My problem is how to manage the concurrency when the users need to create an invoice number.
Hi, can anyone teach me how to automatic create a invoice number and insert or update it to a column?

View 3 Replies View RelatedWhat I want to do is :
- restore a backup of a 3rd party database onto one of our servers
- this has no users that I can use
- there is some ETL processing so we're using Control-M to manage the process
- create a database user and grant it db_reader.
I'd like to do this without granting any users elevated privileges if possible.
What I've done so far is grant the Control-M user (this is a domain user) dbcreator rights and made it owner of our copy of the database that is being refreshed.
The refresh is completing, but Control-M is not able to log onto the database to create the user.
What is the best way to accomplish this task without granting the control-m user sysadmin rights?
Would I be able to do it if I used a SQL Agent job for the restore and user creation?
How to create a row number for a consecutive action. Example: I have a listing of people who have either completed a goal or not. I need to count by person the number of consecutively missed goals.
My sql table is this:
PersonId, GoalDate, GoalStatus (holds completed or missed)
My first thought was to use the rownumber function however that doesn’t work because someone could complete a goal, miss a goal, then complete one and when they complete a goal after a missed goal the count has to start over.
add a number to the end of an ID to create a series.For example, I have an EventID that may have many sub events. If the EventID is 31206, and I want to have subEvents, I would like have the following sequence. In this case, lets say I have 4 sub Events so I want to check the EventID and then produce:
312061
312062
312063
312064
How can I check what the EventID is, then concatenate a sequence number by the EventID?
All I have a table full of invoices and in that table there is a field named HCC. An invoice can contain multiple HCC's. I also have a table named hierarchical codes (below is an example)
(COL1)HCC...........(COL2)If any of the HCCs in this column exist on an invoice along with the HCC in column 1 then use HCC listed in column one
1
2
3.......................4
4
6
8.......................9 ,10 ,11 ,12 ,13
[code]...
I want to return invoice 1 with HCC set to 34 since the hierarchy for when any of these HCCs (35 ,36 ,37 ,38) exist on an invoice along with 34 is 34.
Hi there
I need a bit of generic advice about a project I am currently working on which is slightly out of my comfort zone. I€™m using SQL 2005 and VB.Net to develop an application that produces invoices for a number of different countries. The issue is that the data is arriving from an AS400 system so the tables I am working from are a little strange! This results in a fair degree of work tweaking the data into a format that is useful for my application.
To simplify the explanation each invoice in its basic form consists of the invoice data and the line items (so there is nothing new here). What is unusual is that the invoice data has an invoice number but then an additional invoice number specific to the country it is destined for. The initial invoice number arrives with the data from the AS400 but the secondary number is generated according to a number of business rules.
I have written an update query in a stored procedure which updates the invoice data with a number of values from a secondary table and a number of calculated values. There are several functions, one in particular which looks up the new invoice number from a secondary table based on specific criteria (country of destination being one of them) and I had intended to write an update query, called from within this function which then increments the invoice number but I have since found out that you cant do an update/delete from a function?
I can€™t add an update query to increment the value after the initial update query as this results in the stored procedure running through and adding all the invoice numbers (which are the same) and then the number being incremented at the end.
I assume I can€™t call an update query from within the initial update query so that the increment takes place after each loop of the initial update (if I can what would the syntax be?).
I have tried writing a trigger which completes the increment when the invoice data is updated. I haven€™t used triggers before but once again it appears as if the first update query is running through and completing all the updates and then the trigger fires incrementing the number. Or have I just got this wrong?
I guess what I need is a trigger which fires after each row of the table is updated which was how I assumed it should work!
Ironically I could write this in VB.Net with ease but for speed we need it within the database.
What is the best way to increment my invoice number?
I€™m sorry of this is general in nature but im really looking for some advice as to the best approach to deal with this issue.

I have a user that I have granted the server role "securityadministrator" and a database role "db_securityadmin". When logged inas this user I can create new logins but not run sp_adduser to add thenew login to as this says I don't have permission to do this. I canhowever run sp_revokedbaccess to get rid of a user from the database.

I have a requirement to allow a user to restore a database and then create database users and add them to the db_owner database role. The user must not have sysadmin rights on the server.
The database restore works ok by placing the user in the dbcreator role.
There is a stored procedure to create the database user and alter role membership, I want the user to execute the sp as a different, higher privilege account so as not to give the user underlying permission to create users in the database.
USE [master]
GO
/****** Object: StoredProcedure [dbo].[sp_create_db_users] Script Date: 22/07/2014 13:54:46 ******/
SET ANSI_NULLS ON
GO
[Code] ....
The user has execute permission on the stored procedure but keeps getting the error:
Msg 916, Level 14, State 1, Line 2
The server principal "Mydomainadmin1" is not able to access the database "Mydatabase" under the current security context.
Mydomainadmin1 has dbowner to Mydatabase and sysadmin rights for server. If the 'execute as' is changed to 'caller' and run by mydomainadmin1 it works so the issue is between the execute sp and the actual running of the procedure.
Can you help me with SQL issue I€™m stuck on?
I wish to take source data that looks like this:
Invoic_num
Line_num
6658
0
6658
2
6658
8
7721
2
7721
3
And rebuild the line numbers like this:
Invoic_num
Line_num
6658
1
6658
2
6658
3
7721
1
7721

This seems completely impossible to me. So I was thinking that maybe a second procedure using update could be run against the table after the initial build.
We have a 2-tier architecture with thick client (.NET 2.0) applications directly accessing the SQL Server database. We are struggling to manage lots of users while maintaining security. Granting lots of users directly to the database seems to be tough to manage. In fact, we would like to let supervisors without DBA previlege to add and remove users of our applications. Using SQL Authentication (a single account to access the database) is the other alternative but it is not considered as a secure solution.
I would appreciate if anyone gives me suggestions on how to handle this, without moving to a 3-tier architecture (dedicated middle-tier DB access layer running a custom user account).
Thanks in advance.

Other than right-clicking on each individual table in SSMS and generating a CREATE script, is there a simple way to generate CREATE TABLE scripts for tables within a given database?
Background: I have a bunch of tables in one database, and I would like to add tables to a second database that have the same names and basic structures of some of the tables from the first database.
I do not need to transfer any data from the tables, this is a seperate project that will use a similar data structure. I just want to generate the CREATE TABLE scripts for 30ish tables within the first database, and then I'll tweak the scripts as appropriate and run them against the new database.

View 4 Replies View RelatedHi,
could somebody please let me know what is the maximum number of simultaneous users/connection per single SQL Server 7.0 box? Licenses are not the issue here, rather the number of physical connections supported before another server needs to be purchased.
Another variation of this question would be what's the highest number of databases that 7can be created on SQL 7.0 server and what is the highest number of physical connections supported per database? Again, licenses are not the issue. Thanks a lot in advance.
Table structure: col1 IDENTITY (seed=1 increment=1) + few other columns (col2...col7) + one text column (col 8)
I have around 50,000,000 rows per day inserted in the table T1. At the end of the day 40,000,000 rows are deleted. I have to keep the records for 12 months and then archive it. Database is 24/7 web serving and there is no down time allowed. IDENTITY column will go out of range (overflow) after less than two years, unless the identity seed is reset to the start value (seed=1, increment=1).
At the end of 12th month data is archived in another table and only last month is kept in the table T1. So table T1 enters new year with data from last month of the previous year. There are few other tables that refer to this table by using there own field with values from T1.IDENTITY column (referential integrity is not enforced). Identity column in T1 is needed as a unique id for some search actions. Performance is an issue therefore bigint data type is used for this identity column rather than decimal.
Another problem I have is how to do table update on one column (1 mil rows to be updated out of 2 mil of rows) with the minimum impact on the users who are querying this table heavily. Not need to mention that it is web app 24/7 no down time.
Thank you in advance.

I want to use the info to control concurrent licensing for my Application
Our development team wanted to create a database user for each application user in the application and use these for granular data access control, which at first, sounded like a good idea but our initial testing ran into some interesting results.
Our target user base was about 15 million users with an estimated 1% concurrency rate, and finding no MS documentation on an upper limit to the number of users a database can have we began some load testing to see how the database performed. In the hundreds of thousands of users range our test database had a hard time performing well under light loads (even without any concurrent connections).
When we purged the users and reverted back to just a handful of service accounts, performance went back to "normal" under the same loads. I began to wonder if this is a situation where throwing more hardware at the problem would overcome the issue or if there is a practical upper limit to the number of users a single database can handle well.
(There were of course other cons to this arrangement and I certainly was never going to expand the users tree in the object explorer for a database like this, but we thought it a solution worth investigating.)
What is the largest number of users any of you have had in a single database?
Our company has 2 Database Roles (DBE and DBA). The DBE creates
database schema, performs SQL Server Administration, and manages server
security. The DBA writes data access, ETL, and manages database
security. In 2005, we're struggling with how to allow the DBA to see
all of the logins on the server in order to add them as users of their
database. What permissions does the DBA need to select from any of the
logins on the server to add them to their database?

Write a CREATE VIEW statement that defines a view named Invoice Basic that returns three columns: VendorName, InvoiceNumber, and InvoiceTotal. Then, write a SELECT statement that returns all of the columns in the view, sorted by VendorName, where the first letter of the vendor name is N, O, or P.
This is what I have so far,
CREATE VIEW InvoiceBasic AS
SELECT VendorName, InvoiceNumber, InvoiceTotal
From Vendors JOIN Invoices
ON Vendors.VendorID = Invoices.VendorID

I am migrating a database TESTDB from SQL 2008R2 to a new server running SQL Server 2012.
Management has decided the current sql users should have "better" user names. So the login and username "BadUsername" on the old server should be called "GoodUserName". Goodusername should have the same permissions as Badusername.
I have now restored a backup from the old server to the new server.
I used the following script for creating the login:
CREATE LOGIN [GoodUserName] WITH PASSWORD=N'difficultpassword', DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO
Then I run the following script:
ALTER USER Badusername WITH LOGIN = GoodUserName, NAME = GoodUserName
But the results are not what I wanted. I now have two database users: Badusername and GoodUserName. I would have preferred if BadUserName was "replaced" by GoodUserName, but it won't be a problem if I have to delete badusername manually. Worser is that GoodUserName have NOT "inherited" any permissions from Badusername.
Is there an easy way to transfer permissions or do I need to loop through the permissions of badusername and apply those to badusername?
I have a few databases that are using Partitioned Views in order to manage the table sizes and they all work well for our purposes. Recently I noticed a table that had grown to 400+ million rows and want to partition it as well, so I went about creating new base tables based on the initial table's structure, just adding a column to both table and primary key to be able to build a Partitioned View on them.The first time around, on a test system, everything worked flawlessly but when I put the same structure in place on the production system I get the dreaded "UNION ALL view 'DBName.dbo.RptReportData' is not updatable because the primary key of table '[DBName].[dbo].[RptReportData_201405]' is not included in the union result. [SQLSTATE 42000] (Error 4444)" error.
I have searched high and low and everything I see points to a few directives in order for a UNION ALL view to be updatable:
- Need a partitioning column that is part of the primary key
- Need a CHECK constraint that make the base tables exclusive, i.e. data cannot belong to more than one table
- Cannot have IDENTITY or calculated columns in the base tables
- The INSERT statement needs to specify all columns with actual values, i.e. not DEFAULT
Well, according to me, my structure fulfills these conditions but the INSERT fails anyway. CREATE scripts below scripted from SQL Server. I only modified them to be on a single row - it is easier to verify that they are identical in a text editor that way.

In the Project Web Access (PWA 2010), I have created Report Library which contains .rdl files --> Manage Subscription --> Add Subscription --> Email subscription is missing
Did i missed out some thing but other email functionalities like notifications, Approval workflow are working fine so no issue with SMTP.
Quick question, is there a limitation on the number of users that can get into SQL server at one time? Say 1500 or 2000 users? If not, I wonder how many users can actually cause the performance of the server to have a significant drop.

Hi all,
I have to create a DSN for SQL-Server. Therefor I use the function "SQLConfigDataSource" from "ODBCCP32.DLL". But the problem is that the SQL-Server does not use the Standard-Portnumber 1433. I've tried to make the DSN with "SERVERNAME xxxx" where xxxx is the Portnumber, sometimes it works, but often it does not. When it does not work, then the Checkbox in the ODBC-Configuration-Tool is checked, so the connection is searching for the standard-port. How can I tell the system that it shall NOT use dynamic configuration?
Thanks for help,

I am having problems getting my last revision number out when i am trying to use inner joins along with the row_number over partition
I am using 2 tables, tbl_acyear_lookup & tbl_targets
tbl_acyear_lookup columns = (pk)- academic_year_id, academic_year
looks like this:
1, 2010/2011
2, 2011/2012
3, 2012/2013
tbl_targets columns = targetID, Academic_Year_ID,Course_Mode,UK_ENROL, INT_ENROL, Notes, Revision_Number
I have one stored proc that uses the Row_number over partition that looks like this:
Select TargetID, Academic_Year_id, Course_Mode, UK_Enrol, Int_Enrol, Notes, Revision_Number from
(SELECT ROW_NUMBER() OVER (partition by [Academic_Year_id] order by [Revision_Number] DESC) as [RevNum],TargetID, Academic_Year_id, Course_Mode, Target_Year, UK_Enrol, Int_Enrol, Notes, Revision_Number
FROM tbl_targets where course_mode=@course_mode) RV where (RV.RevNum=1)
Now the next store proc needs to use the above but i need to add the Academic_year from the tbl_acyear_lookup table also add filter the target_year ='year 1'
