Within a stored procedure I'm getting the next value of a reference
number using (simplified):
BEGIN TRANSACTION
@next_ref=select max(ref) from table
insert into table (ref) values (@next_ref+1)
create related records in other tables.
COMMIT TRANSACTION
I'm getting duplicate values in a multi-user network, presumably
because the new record is not commited until the transaction is
complete and another user starts another transaction and reads the same
max value.
Can anyone suggest a way of ensuring unique values? Perhaps by locking
the table for the duration.
There is already a separate identity column that increments ok.
HI, I keep getting this warning with a lookup (full cache mode) that retreives data form a table that contains the following information:
SRCE_SYS TABLE_NAME FIELD_NAME CODE ENGLISH_DESCRIPTION STATIC STATIC PM_PC_TX_TYPE_CODE G GROSS STATIC STATIC PM_PC_TX_TYPE_CODE E EXCESS STATIC STATIC PM_PC_TX_TYPE_CODE F FACULTATIVE STATIC STATIC PM_PC_TX_TYPE_CODE S SURPLUS STATIC STATIC PM_PC_TX_RIDER_CODE BOAT BOAT STATIC STATIC PM_PC_TX_RIDER_CODE RIDER RIDER STATIC STATIC PM_PC_TX_RIDER_CODE CONT CONTENTS
The column tab matches SRCR_SYS, TABLE_NAME and FIELD_NAME (using constants defined in a derived column transform) .The code column comes from the source. We want to retreive the english_description colum from SRCR_SYS, TABLE_NAME,FIELD_NAME and CODE in the dataflow.
I would normally ignore the warning but sometimes, it seems that the lookup does not match any values and enabling memory restriction on the advanced tab resolve the issue and suppress the warning.
As I said, I keep getting this warning and I don't know why since there are no duplicates in the table? Am I missing something?
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.
I am using vs 2010 to write my dtsx import scripts.I use a script component as a source to create a flat file destination file.Everything have been working fine,but then my development machine crashed and we have to install everything again.Now when i use the execute package utility to test my scripts i get the following error:
Error system.NullReferenceException: Object refrence not set to an instance reference.
In PreExecute section TextReader = new system.io.streamreader(" file name") In the CreateNewOutputRows: dim nextLine as string nextLine = textReader.ReadLine
[code]...
is there something which i did not install or what can be the error?
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.
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)
I am using the Import/Export wizard to import data from an ODBC data source. This can only be done from a query to specify the data to transfer.
When I try to create the tables, for the query, I am getting the following error:
Msg 2714, Level 16, State 4, Line 12
There is already an object named 'UserID' in the database.
Msg 1750, Level 16, State 0, Line 12
Could not create constraint. See previous errors.
I have duplicated this error with the following script:
USE [testing]
IF OBJECT_ID ('[testing].[dbo].[users1]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users1]
CREATE TABLE [testing].[dbo].[users1] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users2]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users2]
CREATE TABLE [testing].[dbo].[users2] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
IF OBJECT_ID ('[testing].[dbo].[users3]', 'U') IS NOT NULL
DROP TABLE [testing].[dbo].[users3]
CREATE TABLE [testing].[dbo].[users3] (
[UserID] bigint NOT NULL,
[Name] nvarchar(25) NULL,
CONSTRAINT [UserID] PRIMARY KEY (UserID)
)
I have searched the "2714 duplicate error msg," but have found references to duplicate table names, rather than multiple field names or column name duplicate errors, within a database.
I think that the schema is only allowing a single UserID primary key.
I've begun to get the above error from my package. The error message refers to two output columns.
Anyone know how this could happen from within the Visual Studio 2005 UI? I've seen the other posts on this subject, and they all seemed to be creating the packages in code.
Is there any way to see all of the columns in the data flow? Or is there any other way to find out which columns it's referring to? Thanks!
In a pretty standard select statement (as shown), i want to return 0 when "dbo.v_AgentOrderTotals.Total - dbo.v_AgentAmmountPaid.total - dbo.v_AgentCommClean.total AS amount_outstanding_commission" is less than 0.

I have a sales report that includes dollar amount, tonnage, and profit margin among other things. They are currently sorted by tonnage sold from highest to lowest. I'd like to be able to place a number in a column counting 1 up for tonnage ranking. I'd also like to get a number ranking for sales amount ranking along with profit margin ranking. The most tonnage sold might not have been the biggest sale nor had the highest profit margin.
Does this sound like something that can be done within SSRS?
I should ad I'm runing MDX queries against a cube so I can't use T-SQL for ranking.
DECLARE Loan_cursor CURSOR FOR SELECT Loan_No,store FROM loan WHERE maturity_date > '2001-04-30' and loan_no like 'ABL%'

when l run the cursor l get the error Server: Msg 207, Level 16, State 3, Line 15 Invalid column name 'Loan_No'. . If l reference it as Set @LoanNo = LoanTable.Loan_No l get the error
Server: Msg 107, Level 16, State 3, Line 15 The column prefix 'loan' does not match with a table name or alias name used in the query. All l'm trying to do is to compare the loan number that l get from the cursor to the value in the loans table. Maybe reference is a better word
Just i modified one sub stored procedures which is not getting affected in the main stored procedures

set nocount off end
In data_transfer_sp,i have commented the select statement but still iam use to the select result while execution the main sp. Note:I have compiled the data_transfer_sp after making comment .Txs in advance
Hi, Is it possible to search in columns with a number datatype (I'm using an MS SQL database with bigint columns) with the ICriterion Expression.Like? Normally the Expression.Like is used for varchar columns. However, if there's a bigint column with the value 167829 I want to search for example on %678%. Cheers, koekie
I needed to come up with an algorithm to create unique user- friendly account numbers such as AC0000000001, AC0000000002, etc...Where they increment by 1. I created a SQL function that retrieves the previous number generated, adds 1 to it, inserts the new value into the table, then returns the new value. I started thinking, what if the function is ran at the same time? What if function # 1 creates the new number, and function #2 creates a new number as well before function #1 inserts it? Is this a possible scenario? If so, how do I lock the process until the function completes to prevent this? Thanks for any help you provide.
I am developing a ASP.NET application using SQL Server as my database. I want to create a number that is unique.
The number will have 8 digits.
first 2 digits correspond to year. ex:04 or 03
the next 6 digits start with 000001 and it should get added for each new entry of data.
i am not able to generate number in the way i said. I am relatively new to SQL. so any suggestions as how to go about solving the problem???. Are there any samples/codes available for this.
How to generate serial numbers ? I had already tired ident. i am getting the error. Can any people who is willing to write a syntax for me.
In sybase if we use Number * function. It will automatically generates the serial numbers from 1 to n. similarly i need the same function in SQL server 7.0 so that my problem will be solved...
I am converting sybase stored procedure into sql server stored procedure that is why i am asking about that. i am struggling hard to find an answer...
Looking for a way to round numbers to a specified number of significant digits. The ROUND function rounds to a specific decimal place but does not take into account the level of significance of the remaining numbers. (i.e. ROUND(7.12435,2)=7.12000) The type of function I need would round the number in the following manner: SigFigRound(7.12435,3)=7.12 or SigFigRound(7.12345,1)=7.
Hello, I am trying to run a query select logid, count(logid) from temp2 group by logid order by logid compute sum(count(logid)) when I get the result the numbers are being truncated eg instead of 10471066 it shows 104710 so last two digits get truncated. Any ideas or hints appreciated. Thanks HP
After working out the basics and getting a report to give me back rows based upon a dropdown list, i know want to ask how do i show the sum of values for a customer.
So the out put would look something like this
Customer Total 0001 12234.56 0002 232.98 0003 456.78
I have two tables "customer" and "trades" i all ready have them linked and giving me all the individual items, oh and i have got it doing BETWEEN to dates, but i would really like to know how to show just the TOTAL trades for each cutomer on each line not every single trade for the customer.
I have the following table: CREATE TABLE ITEMS ([ITEMID] int, [itRULE] varchar(1)) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (11, 3) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (12, 3) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (21, 2) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (22, 2) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (31, 1) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (32, 1) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (41, 0) INSERT INTO ITEMS (ITEMID, itRULE) VALUES (42, 0)
-- Those works and gives me 11,12,21,22 SELECT ITEMID FROM ITEMS WHERE itRULE IN (2,3) SELECT ITEMID FROM ITEMS WHERE itRULE IN ('2','3')
-- This doesn't works declare @Rule varchar(10) set @Rule='2,3' SELECT ITEMID FROM ITEMS WHERE itRULE IN (@Rule) Any idea? I don't mind to change the data type if it works.
I am trying to get random numbers to have a unique value for different processes, then I can identify each process. What happens is that I use rand() function without seed, so I got my random numbers, but after shutting down SQLServer and try to get again another random number after booting up, the same series of random numbers is given again and again. So if anyone knows how I can get unique values,even though reseting the server, and using random function or any other method which automatically provides unique values,I'll really appreciate it if you let me know it.
I have two identical databases. I need to delete the even customer numbers from the first database and the odd numbers from the other database. I know I can do this writing a delete statement for each table. However there are a total of 54 tables.
Does anyone know a faster way to write the script without writing 54 scripts?
I have a table which will recieve and interface file to be loaded. All the fields are there except an account_id field which is a char(12), but the data is a number 000000000001, 000000000002, etc. These numbers are to be incremented by one. I understand how to write the process using a cursor to run through all the records and to increment them before loading. My question is the best way to get the max number in the existing table which is the char(12) , and icrement the number by one, but retain the leading zeroes I will need. Anyone had the pleasure of doing this providing input greatly appreciated.
