Here is a piece of code I found in an application I'm supporting.
Problem: We're seeing duplicate numbers and I think this code may be the source of it.
At first glance I did not understand how it worked.
It locks a table <begin tran> , updates a number, reads that number, then commits. This code appears to work - it returns the newly added number.
My Question - How? How can this code return a value that is not "Committed" to the database yet. Please critique..... I have an alternate method, please comment on it as well. Thanks for your input.
--THIS IS WHAT I FOUND....
CREATE PROCEDURE sp_UpdateOrderNumber @customer int AS
DECLARE @NewOrderId int,
BEGIN TRAN
UPDATE CUSTOMERS
SET ORDER_NUMBER=ORDER_NUMBER + 1
WHERE COMPANY_ID=@customer
SELECT
If @@ERROR <> 0 OR @@ROWCOUNT <> 1 /* Check for Errors */
Begin
Rollback Tran
Return -999
End
SELECTORDER_NUMBER
FROMCUSTOMERS
WHERECOMPANY_ID=@customer
SELECT
If @@ERROR <> 0 OR @@ROWCOUNT <> 1 /* Check for Errors */
Begin
Rollback Tran
Return -998
End
COMMIT TRAN
My Newly suggested method. Using Implicit transaction.
I believe this is more "concurrency" friendly. Do you?
Begin loop until success
Read Number
Update to Number+ 1 WHERE number is the one I just read
If row was updated, use this new number and set success flag
Loop
Is there a way to make the primary ID as Identity Column to always be in order? For example, I have 5 rows with ID 1,2,3,4,5. If I delete record number 5 and then added another record, the ID shows up as 6 and not 5. Or if I delete record number 3, the next ID is going to be 6 instead of 3. I like to keep all my ID in order if possible and not skipping if that is even possible or should I use that practice.
Is there any option to get the velue of auto increment number before inserting record.
My problem is that I want to get the auto increment number, for this I am using MaxId function, but If i have deleted the some rows from table, I could not get the actual.
For example there are 20record s in the table I have delete the last 3 records now I have the last value of Identity is 17. When I used the Maxid function It gives me the 18 number. But I need 21.
will it be possible to increase number as below automatically000000010000000200000003....whenever the row is inserted, number will be increased like aboveformat.which data type should I select and do some other setting to recordlike that?thanks
I have one master table and multiple detail tables. The primary key of the master table is an auto-increment number, which is a foreign key in those detail tables. I am wondering if SQL Server allows us to get the next available auto-increment number of the master table up front. Thanks a lot.
What are the guildelines to detect a possible phatom/s? When will I set the transaction isolation level to SERIALIZABLE ? What will be the best ratio of consistency-concurrency in our database? Any info will be highly appreciated...
Hi, in Access, I can use an Auto-Increment number for my primary key field. May I know how do I do that in SQL Express?
In addition, is there any tutorial on how to use SQL Express to generate customised unique numbers (such as membership number, Customer ID such as A001 where A is based on the customer's name while 001 is due to the fact that the customer is the first among those with names starting with A)?
writing the procedure for incrementing the number based on alphabets from A-Z
for example:
if alphabet is A then increment should be A001,next A002..etc if alphabet is B then increment should be B001,next B002...etc . . . . if alphabet is Z then increment should be Z001,next Z002...etc

I need to create a script that adds an incrementing suffix to two columns, but restarts based on the value of another column. I found a similar question in the SQL Server 2000 forum, but it doesn't quite fit and also I'm working with SQL Server 2008 R2. The code below both creates a table with test data and tries to carry out the task. If you run this, you will see that the VISITNUM column has a value of UNS in row 4, UNS.1 in row 5 and UNS.2 in row 6. In row 7 it's V200, then in rows 8 and 9 it's UNS.3 for both. The same suffix gets applied to the VISIT column, but of course if I can solve this for VISITNUM then adding the suffix to VIST as well will be easy.
What I need is for row 8 to have UNS and row 9 to have UNS.1. In other words, any time the VISITNUM is UNS several times in a row, I need to add that ".X" suffix, but if a row has something other than UNS, I need to start over again the next time it's UNS again.
I need to have a script where it ask the user for a value, the script will search for all records that match the value. Then it will display the numbers of records found and ask the user to enter a different value. The rest of the script will use this new value and increment by 1 n times as the number of records found. I started the script where it will ask for "HANDLE" and display the number of records found with that "HANDLE"
declare @HANDLE as varchar(30) declare @COUNT as varchar(10) declare @STARTINV as varchar(20)
set @HANDLE = ?C --This is the parameter to search for records with this value set @STARTINV = ?C --User will input the starting invoice number SELECT COUNT as OrderCount FROM SHIPHIST where HANDLE = @HANDLE
I just can't figure out how to proceed to use the entered invoice # and increment by 1 until it reach the number of records found.
This will be the end results:
Count=5 --results from query STARTINV=00010 --Value entered by user
Books online mention the existence of sample code for several custom tasks, including the one mentioned in the title. But, when I try to find this code in the location mentioned it is nowhere to be found.
I have run a search on the rest of my drive and come up empty.
I Have a table that needs to have 2 unique number.
detail_id and detail_print_id.
detail_id is already an IDENTITY.
both fields need to be different, because when importing, it imports the same data into a table twice, with only a slight data change (and id is not one of the changes).
So I thought i could do the following:
detail_id INT NOT NULL IDENTITY(1,2), detail_print_id INT NOT NULL IDENTITY(2,2), --blah blah
that way, the detail_id will always be odd, and the detail_print_id will always be even. however SQL Server 2005 only allows 1 identity per table, and both these fields need to be auto generated when the field is inserted, so as to prevent double data.
is there anyway I can create a int column to auto increment, without the column being an IDENTITY??
also, I would prefer to not have to create a second table with a single column just for this work.
I have sql code that returns the correct number of record when run without an aggregate function like count(myfield) and group by myfield. It always returns 86 row which is correct when Select DISTINCT is used. As, expected when DISTINCT is not used I get double the number if rows or 172. But when I count(myfield) and group by myfield the count is 172 and not 86. The strangest thing about this is that when I am grouping a set of items
Group 1
Group 2
Group 3
The other group sum up correctly while others don't. What can explain this? Here is the code.
Select DISTINCT ws.p4Districtnumber, ws.cycle, ws.worksetid, count(msi.MeterSessionInputKey) as ASND from fcs.dbo.WorkSet as ws left outer join fcs.dbo.WorkAssignment as wa on ws.WorkSetID = wa.WorkSetID left outer join fcs.dbo.MeterSessionInput as msi on wa.worksetkey = msi.worksetkey
Hi all--I'm trying to convert a function which I inherited from a SQL Server 2000 DTS package to something usable in an SSIS package in SQL Server 2005. Given the original code here: Function Main() on error resume next dim cn, i, rs, sSQL Set cn = CreateObject("ADODB.Connection") cn.Open "Provider=sqloledb;Server=<server_name>;Database=<db_name>;User ID=<sysadmin_user>;Password=<password>" set rs = CreateObject("ADODB.Recordset") set rs = DTSGlobalVariables("SQLstring").value
for i = 1 to rs.RecordCount sSQL = rs.Fields(0).value cn.Execute sSQL, , 128 'adExecuteNoRecords option for faster execution rs.MoveNext Next
Main = DTSTaskExecResult_Success
End Function
This code was originally programmed in the SQL Server ActiveX Task type in a DTS package designed to take an open-ended number of SQL statements generated by another task as input, then execute each SQL statement sequentially. Upon this code's success, move on to the next step. (Of course, there was no additional documentation with this code. :-)
Based on other postings, I attempted to push this code into a Visual Studio BI 2005 Script Task with the following change:
public Sub Main()
...
Dts.TaskResult = Dts.Results.Success
End Class
I get the following error when I attempt to compile this:
Error 30209: Option Strict On requires all variable declarations to have an 'As' clause.
I am new to Visual Basic, so I'm on a learning curve here. From what I know of this script: - The variables here violate the new Option Strict On requirement in VS 2005 to declare what type of object your variable is supposed to use.
- I need to explicitly declare each object, unless I turn off the Option Strict On (which didn't seem recommended, based on what I read).
Given this statement:
dim cn, i, rs, sSQL
I'm looking at "i" as type Integer; rs and sSQL are open-ended arrays, but can't quite figure out how to read the code here:
This code seems to create an instance of a COM component, then pass provider information and create the recordset being passed in by the previous task, but am not sure whether this syntax is correct for VS 2005 or what data type declaration to make here. Any ideas/help on how to rewrite this code would be greatly appreciated!
Table 1: AddressBook Fields --> User Name, Address, CountryCode
Table 2: Country Fields --> Country Code, Country Name
Step 1 : I have created a Cube with these two tables using SSAS.
Step 2 : I have created a report in SSRS showing Address list.
The Column in the report are User Name, Address, Country Name
But I have no idea, how to convert this Country Code to Country name.
I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]
Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.
Hello, I'm using ASP.Net to update a table which include a lot of fields may be around 30 fields, I used stored procedure to update these fields. Unfortunatily I had to use a FormView to handle some TextBoxes and RadioButtonLists which are about 30 web controls. I 've built and tested my stored procedure, and it worked successfully thru the SQL Builder.The problem I faced that I have to define the variable in the stored procedure and define it again the code behind againALTER PROCEDURE dbo.UpdateItems ( @eName nvarchar, @ePRN nvarchar, @cID nvarchar, @eCC nvarchar,@sDate nvarchar,@eLOC nvarchar, @eTEL nvarchar, @ePhone nvarchar, @eMobile nvarchar, @q1 bit, @inMDDmn nvarchar, @inMDDyr nvarchar, @inMDDRetIns nvarchar, @outMDDmn nvarchar, @outMDDyr nvarchar, @outMDDRetIns nvarchar, @insNo nvarchar,@q2 bit, @qper2 nvarchar, @qplc2 nvarchar, @q3 bit, @qper3 nvarchar, @qplc3 nvarchar, @q4 bit, @qper4 nvarchar, @pic1 nvarchar, @pic2 nvarchar, @pic3 nvarchar, @esigdt nvarchar, @CCHName nvarchar, @CCHTitle nvarchar, @CCHsigdt nvarchar, @username nvarchar, @levent nvarchar, @eventdate nvarchar, @eventtime nvarchar ) AS UPDATE iTrnsSET eName = @eName, cID = @cID, eCC = @eCC, sDate = @sDate, eLOC = @eLOC, eTel = @eTEL, ePhone = @ePhone, eMobile = @eMobile, q1 = @q1, inMDDmn = @inMDDmn, inMDDyr = @inMDDyr, inMDDRetIns = @inMDDRetIns, outMDDmn = @outMDDmn, outMDDyr = @outMDDyr, outMDDRetIns = @outMDDRetIns, insNo = @insNo, q2 = @q2, qper2 = @qper2, qplc2 = @qplc2, q3 = @q3, qper3 = @qper3, qplc3 = @qplc3, q4 = @q4, qper4 = @qper4, pic1 = @pic1, pic2 = @pic2, pic3 = @pic3, esigdt = @esigdt, CCHName = @CCHName, CCHTitle = @CCHTitle, CCHsigdt = @CCHsigdt, username = @username, levent = @levent, eventdate = @eventdate, eventtime = @eventtime WHERE (ePRN = @ePRN) and the code behind which i have to write will be something like thiscmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@eName", ((TextBox)FormView1.FindControl("TextBox1")).Text);cmd.Parameters.AddWithValue("@ePRN", ((TextBox)FormView1.FindControl("TextBox2")).Text); cmd.Parameters.AddWithValue("@cID", ((TextBox)FormView1.FindControl("TextBox3")).Text);cmd.Parameters.AddWithValue("@eCC", ((TextBox)FormView1.FindControl("TextBox4")).Text); ((TextBox)FormView1.FindControl("TextBox7")).Text = ((TextBox)FormView1.FindControl("TextBox7")).Text + ((TextBox)FormView1.FindControl("TextBox6")).Text + ((TextBox)FormView1.FindControl("TextBox5")).Text;cmd.Parameters.AddWithValue("@sDate", ((TextBox)FormView1.FindControl("TextBox7")).Text); cmd.Parameters.AddWithValue("@eLOC", ((TextBox)FormView1.FindControl("TextBox8")).Text);cmd.Parameters.AddWithValue("@eTel", ((TextBox)FormView1.FindControl("TextBox9")).Text); cmd.Parameters.AddWithValue("@ePhone", ((TextBox)FormView1.FindControl("TextBox10")).Text); cmd.Parameters.AddWithValue("@eMobile", ((TextBox)FormView1.FindControl("TextBox11")).Text); So is there any way to do it better than this way ??

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
in my sql, i want to change a decimal number to percent format number, just so it is convenient for users. for example there is a decimal number 0.98, i want to change it to 98%, how can i complete it?
I am currently designing a SSIS package to integrate data into a data warehouse fact table. This fact table has about 70 columns among which 17 are foreign keys for dimension tables.
To insert data in that table, I have to make several transformations and lookups. Given the fact that the lookups I have to make are a little complicated, I have about 70 tasks in my Data Flow. I know it's a lot, but I can't find a way to make it simpler. It seems I really need all these tasks.
Now, the problem is that every new action I try to make on the package takes a lot of time. At design time, everything is very slow. My processor is eavily loaded each time I change a single setting in one of the tasks, and executing the package in debug mode takes for ages. If I take a look at the size of my package file on disk, it's more than 3MB.
Hence my question : Are there any limitations in terms of number of columns or number of tasks that can be processed within a Data Flow ?
If not, then do you have any idea why it's so slow ?

If there is one field such as Seq No in a table and if we entered some data .. and if we update one record of Seq No then the below records of Seq No should be incremented in that table

I am looping text files in a folder using foreach. I transfer text file data to sql server. I want to count the total rows are that transferred in all the text files after the foreach loop finishes. I user RowCount but it gives count of only current textfile. It gets reset each time the loop iterates. I want something like @count = @count + currentnoofrows in current text file.
I'm using SQL Server 2000 with MS Management Studio. I have a table that has 400 rows. I have setup the Primary key to increment automatically. How do I setup so that the next record starts at 4001 and up? Right now it starts at 1274, for example. So besides dropping the table and re-creating it, how do reset it so it counts from sequentially from the last row inserted?
