Locking And Rowid
Jul 20, 2005
Hello!
1. How can I know exactlly what row is locked? Is data in "resource"
column of sp_lock usable? For example, resource = 03000d8f0ecc
511400DB S
GRANT
51142775760271KEY(03000d8f0ecc)
XGRANT
51142775760271PAG1:1112
IXGRANT
51142775760270TAB
IXGRANT
511855753430TAB
ISGRANT
2. Is there any equivalent of ORACLE's "rowid" pseudocolumn? How can I
uniquelly identify some row in any given table ( which may not have
primary key defined )?

In SQL7 books online its written about RID ( row identifier)
Is there any method to use this RID in programming?
Also it stated that the option for row level lock and table level lock can be given explicitly through system procedures. I would like to know how to use these options.
Can any body help ???
Thanx in advance
Vipin.

I am trying to update a SQL db record with ADO commands from an asp page thru a stored proc using the RowID and it is not working. RowID is the Identity seed record.
Here is the stored proc:
CREATE PROCEDURE [sp_Update_tblECMTimeTrackingMain]
@RowID int,
@StartTime datetime,
@EndTime datetime,
@TransxStatus varchar(50)
AS
Begin
UPDATE [tblECMTimeTrackingMain]
SET FStartTime = @StartTime,
FEndTime = @EndTime,
TransxStatus = @TransxStatus
where RowID = @RowID
End
GO
Here is the asp/ado code:
set cmdINSERT = Server.CreateObject("ADODB.command") cmdINSERT.ActiveConnection = strCONN_DATA cmdINSERT.CommandText = "[sp_Update_tblECMTimeTrackingMain]" cmdINSERT.CommandType = 4
set param = cmdINSERT.CreateParameter("@RowID",3,1,4) cmdINSERT.Parameters.Append param
set param = cmdINSERT.CreateParameter("@FStartTime",135,1,8) cmdINSERT.Parameters.Append param
set param = cmdINSERT.CreateParameter("@FEndTime",135,1,8) cmdINSERT.Parameters.Append param
set param = cmdINSERT.CreateParameter("@TransxStatus",129,1,50) cmdINSERT.Parameters.Append param
cmdINSERT.Parameters(0) = CInt(mACTREFNUM) ...when I change this to "568" it actually does the update. Yes there is something in mACTREFNUM.
cmdINSERT.Parameters(1) = meStartTime
cmdINSERT.Parameters(2) = meEndTime
cmdINSERT.Parameters(3) = meStatus
cmdINSERT.Execute lngRECS,,128
Any clues?

Hi,
I'm new to Sql Server. I have a jdbc program which gets data from
tables in a Sql Server database and inserts it into the corresponding
tables in an Oracle database. This program is supposed to run in an
infinite loop. On every run of the program, it should get the rows
added after the last run. Is there any way I could get the rowid of the last record?
I know that there is no visible rowid in Sql Server. Can anyone please suggest a way
around this problem? It would be a great help.
Thank you so much.

Hi,
In Oracle we have a datatype called 'ROWID' - Oracle uses this datatype to store the address (rowid) of every row in the database. Do we have any equivalent datatype in SQLServer similar to this ?

Hi all
I have an easy question. In Oracle I can retrieve a column named "ROWID" which returns an unique identifier of the row in the
database. I want to have the same element in SQL Server.
Do you know how is this handle in SQL Server ?
Thanks in Advance

I am getting inconsistent results when BULK INSERTING data from a tab-delimited text file. As part of my testing, I run the same code on the same file again and again, and I get different results every time! I get this on SQL 2005 and SQL 2012 R2.
We have an application that imports data from a spreadsheet. The sheet contains section headers with account numbers and detail rows with transactions by date:
AAAA.1234 /* (account number)*/
1/1/2015 $150 First Transaction
1/3/2015 $24.233 Second Transaction
BBBB.5678
1/1/2015 $350 Third Transaction
1/3/2015 $24.233 Fourth Transaction
My Import program saves this spreadsheet at tab-delimited text, then I use BULK INSERT to bring the data into a generic table full of varchar(255) fields. There are about 90,000 rows in each day's data; after the BULK INSERT about half of them are removed for various reasons.
Next I add a RowID column to the table with the IDENTITY (1,1) property. This gives my raw data unique row numbers.
I then run a routine that converts and copies those records into another holding table that's a copy of the final destination table. That routine parses though the data, assigning the account number in the section header to each detail row. It ends up looking like this:
AAAA.1234 1/1/2015 $150 First Purchase
AAAA.1234 1/3/2015 $24.233 Second Purchase
BBBB.5678 1/1/2015 $350 Third Purchase
BBBB.5678 1/3/2015 $24.233 Fourth Purchase
My technique: I use a cursor to get the starting RowID for each Account Number: I then use the upper and lower RowIDs to do an INSERT into the final table. The query looks like this:
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericTable
WHERE RowHeader LIKE '____.____%'
Results look like this:
But every time I run the routine, I get different numbers!
Needless to say, my results are not accurate. I get inconsistent results EVERY TIME. Here is my code, with table, field and account names changed for business confidentiality.
TRUNCATE TABLE GenericImportTable;
ALTER TABLE GenericImportTable DROP COLUMN RowID;
BULK INSERT GenericImportTable FROM 'SERVERGeneralAppnameDataFile.2015.05.04.tab.txt'
WITH (FIELDTERMINATOR = ' ', ROWTERMINATOR = '', FIRSTROW = 6)
ALTER TABLE GenericImportTable ADD RowID int IDENTITY(1,1) NOT NULL
SELECT RowID, SUBSTRING(RowHeader, 6,4) + '.UBC1' AS AccountNumber
FROM GenericImportTable
WHERE RowHeader LIKE '____.____%'

I have one query which uses a join query to gather all the projects that should show up in someone's list over a period of time (returns and id (int) and name (varchar) paired dataset). I want to do a separate query that takes that list and selects all projects (same paired set ... id and name) EXCEPT where it matches an id on a row of the given result set. The one query looks like this ..DECLARE @startDate datetimeDECLARE @endDate datetimeDECLARE @userId UNIQUEIDENTIFIERSELECT @startDate = ppStartDate FROM ppTablewhere payPeriodID = @payPeriodIDSELECT @endDate = ppEndDate FROM ppTable WHERE payPeriodID = @payPeriodIDSELECT @userId = userID FROM usersTable WHERE userName = @userNameSELECT DISTINCT p.projectID, p.projectNameFROM projectsTable pLEFT JOIN projectMemberhsip m ON m.ProjectId = p.ProjectIdLEFT JOIN timeEntryTable t ON t.ProjectID = p.ProjectIdWHERE t.TimeEntryUserId = @userID AND t.TimeEntryDate >= @startDate AND t.TimeEntryDate <= @endDateORm.UserId = @userID I want to get the same selection from projectsTable WHERE it's not anything from this result set.Haven't been able to get it by modifying the WHERE logic. Is there a way to select all WHERE id != (resultSet from this SELECT)? TIA!

Hi everyone,
I have a question about SQL Server 2005. I have written an ASP.Net 2.0 Web Application and it is using SQL Server 2005 as Database.
In the last few days I noticed that the app is down sometimes. To analyze the problem I looked at the activity monitor in SQL Management Studio. I can see there approximately 170 processinfos.
I want to describe the column values of the process infos:
Process-ID: Unique ID and a red down-showing-arrow-icon
User: My UserDatabase: My DatabaseStatus: sleepingCommand: AWAITING COMMANDApplication: .Net SqlClient Data Provider
When I click Locks by Object, I can see the IDs of the Processinfos. Again I will show some colums:Type: DATABASERequirementtype: LOCKRequirementstate: GRANTOwnertype: SHARED_TRANSACTION_WORKSPACEDatabase: My Database
So my question is, does this mean, that i have locked the db? How are they handled? For example I have a windows service, which is doing checks in db every 10 seconds. I can see, that each check generates a new processinfo?
Is this usual, or am I doing something wrong?
Thnaks for help,Byeee

When I run a select statement : select 'X' from table1 where c1 = condition locking on indexes behaves as expected
However if I run select 1 from table1 where c1 = condition locking on indexes goes wild locking pages and rows on indexes that are not even referenced in the query. Any ideas Why?

I have used DTS in the past to copy information in certain tables in production over the top of those same tables in test. However, the process is now failing. Does DTS require an exclusive lock on the source table, as well as the destination table during the export process? Will shared locks on the table I need to copy prevent DTS from completing the process?

Hi
We are running out of locks while updating a particular table (table name = history, rows = 25,000,000) in SQL Server 6.5.
LE threshold maximum is set to 200.
LE threshold minimum is set to 20.
LE threshold percentage is set to 0.
Locks is set to 0.
I have also included the stored procedure, which we use to update the history table.
As you can see, from the first four lines, we ran this SP 4 times processing around 6 million rows at a time. It runs out of locks once it is around 5.5 to 6.5 million rows. Is there a way of locking the table so that this SP can be run just once which will effectively process all the 26 million rows in one go?
Any help will be greatly appreciated.
