Check Previous Row In The Table
Jul 9, 2004
Hi...
Is there any way to check previous row in SQL Query?
I have a table with these column :
Name1
Name2
Audit_Time (datetime)
Changes
I want to delete record from database in which the Audit_time is <'01/05/2004'.
However before deletion, I want to check, if the Changes value is 'OLD' And the previous value is 'NEW', I will check the Audit_time of the NEW instead of OLD.
Table :
Row Name1 Name2 Audit_Time(mm/dd/yyyy) Changes
1 ABCD EFGH '01/01/2004' ADD
2 ABCD EFGHIJ '01/04/2004' NEW
3 ABCD EFGH '01/04/2004' OLD
4 Klarinda Rahmat '02/08/2004' NEW
5 Klarinda Rahmat '01/04/2004' OLD
In this case, I want to delete row 1,2,3 Where the audit_time are < '01/05/2004'.
Row 5 the audit_time also < '01/05/2004', however the changes='OLD' and the previous value changes='NEW', so I will check the Audit_Time of row 4 which is not < '01/05/2004'.
So I can't delete row5.
Is there any way to check previous row or the row before a specific row in SQL.
Any suggestion is welcomed.
Thank you in advanced.

Hi all,
I wanted to check the previous and next record values.
For example:
sKey NextKey PreviousKey
1 2 Null
2 8 1
8 5 2
5 null 8
I wanted to check the value of NextKey of Prev record and Skey of Next record.
Any idea?
Regards

Hi all,
I wanted to check the previous and next record values.
For example:
sKey NextKey PreviousKey
1 2 Null
2 8 1
8 5 2
5 null 8
Ex : In the first record of the table, the NextKey is pointing to 2.
So the next record of Skey will be 2. The Next Key for this record is 8. Like wise the next record of this should have the Skey as 8.
Now I need to check whether the NextKey and SKey are correct for all rows.
For that I need to check the previous record of "Next key" and next record of "Skey".
Any idea?
Regards

I have two tables. Users and records. I need to select only the users that not has lines recorded in the other table. How could I do that?
Example:
ID| Name| Access 1|Access 2|
----------------------------
1 | Axel | True |False |
2 | Ivan | False |False |
3 | Bob | True |False |
4 | Sue | False |False |
ID| Points| Month| Year|User_1|User_2|
--------------------------------------
1 | 2 | 5 | 2015| 2 | 1 |
2 | 5 | 5 | 2015| 2 | 1 |
3 | 1 | 5 | 2015| 3 | 1 |
Then I want to run a select in the users table, only with the users that hasn't records in the second table.
In the example, the second table has User_1 as the user who receives the points and the User_2 is the user who give the points. Then I would know what user didn't receive 'points' yet.

I have got a table with GUID (PK), COMPANY, CONTACT. There are going to be instances where the company name is the same on multiple records.
What i am trying to do is work out what is the next and previous record
The data is going to be sorted, by COMPANY then GUID.
I am think a stored procedure would be the best to combact this, but very usure how to go about writing it, so i passed the present company and GUID values to it.
Any help would be appreciated, and thanks in advance.

Hello
just wondering, if I can get help with a table (Table A) , where there are few dates and numbers, I have to relate this table to another table (Table B) , where I have whole year working dates
I want to write an expression while making dataset, that if date in table B matches table A, it just get the number from the next column from table A, if it does not matches - it should go back to the date (in table A) - where there is a number.
Like table B has working dates for march, but there are only two dates in table A , for 3/2 (and number is 300) and 3/20 (number 200). So In dataset I want all dates from table B and from 3/2 to 3/19 300 in number column and 200 on 3/20.
Thanks in advance for your help

I'm creating a report in SSRS where we want to do a week-over-week or month-over-month analysis. We have each month and the metrics in a table. By sorting the table ascending, I can grab the previous record using the Previous function in a cell. However, when I order the table descending the previous record is not the correct record to get. In that case I want to grab the next record rather than the previous record. How can I invert the previous function? Or how can i grab the next record in the table rather than the previous?
Thanks!

I need to compare the next row with the previous row of same table and produce nonidentical column.for eg... say my table has
Row 1 => 1001 Abhas 120 150 180
Row 2 => 1001 Abhas 150 150 180
then my output would be as below:
StudId Name fee1 fee2 fee3
1001 120
1001 Abhas 150 150 150
i.e in first row of resultset, i want to show only those values which are changed alongwith studID and next row should display all values.

I want to find previous date from selected date. below is the sample data.
DECLARE @StartDate SMALLDATETIME = '1/11/2016'
declare @tempdat table(repdate smalldatetime)
insert into @tempdat values ('10/26/2015')
insert into @tempdat values ('10/29/2015')
insert into @tempdat values ('11/1/2015')
insert into @tempdat values ('11/27/2015')
insert into @tempdat values ('11/25/2015')
insert into @tempdat values ('11/20/2015')
insert into @tempdat values ('11/10/2015')
insert into @tempdat values ('11/10/2015')
insert into @tempdat values ('11/11/2015')
insert into @tempdat values ('11/11/2015')
Now if i pass the date '10/26/2015' then i want select prev date of passed date. in this example no prev date is available, so result set would be nothing.
if i pass the date '11/10/2015' then result should be '11/1/2015' which is prev small date available in table.

I have a table with score info for each group, and the table also contains historical data, I need to get the ranking for the current week and previous week, here is what I did and the result is apparently wrong:
select CurRank = row_number() OVER (ORDER BY cr.CurScore desc) , cr.group_name,cr.CurScore
, lastWeek.PreRank, lastWeek.group_name,lastWeek.PreScore
from
(select group_name,
Avg(case when datediff(day, asAtDate, getdate()) <= 7 then sumscore else 0 end) as CurScore
[Code] ....
The query consists two parts: from current week and previous week respectively. Each part returns correct result, the final merged result is wrong.

Hi all,I am in the process of creating a page that checks to see if a particular user exists in the database and if it does then send to welcome.aspx if not then accessdenied.aspx. The userid is requested from the query string.I have done some research and cannot find anything directly related, I have tried to add bits of code into what i think is the right place but I dont think what i am doing is correct. Can someone help and show me where my code is going wrong? Also is there a better/more efficient way to do what I am doing?Thanks in advance. default.aspx.csusing System;using System.Data;using System.Data.SqlClient;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class _Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { string UserID = Request.QueryString["uid"]; //string TransferPage; if (UserID != null) { //initiate connection to db SqlConnection objConnect = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString); string sql = "SELECT COUNT(*) FROM members WHERE UserID = '" + UserID + "'"; SqlCommand query = new SqlCommand(cmd, test); int count = (int)query.ExecuteScalar(); int aantal = -1; // some default value if can't insert record if (count == 0) // no existing record for username { Server.Transfer("accessdenied.aspx"); } else { Session["UID"] = UserID; Server.Transfer("welcome.aspx"); } } }}

Hi,
Could someone shed some light on the best way to check a table recordcount before run of DTS pkg.
We have a table that is populated in MS SQL from an Oracle database, and the contents of that table are the basis of a DTS package that we run.
Sometimes Oracle transfer bombs out and the table is empty but our process runs anyway. It screws everything up.
Can we check the recordcount of a table on the server, and if the recordcount > 1 then the process runs, if not, then the process aborts?
Thanks,
Dominic

Hi - please excuse my newness to this. I have a database with several tables and one of them is causing my application to lag really bad. I figure there is either not enough space or something is just wrong in general and i don't know what. Does SQL Server have a shortcut or easy way to test a table in the database?
Thanks =)

Hi all!
I need to check data changes in some tables from specified date. Can it be done without triggers for each table?
SQL Server Management Studio always says "Data was changed" if another user updates data and you try to update old version. How it checks data modification date? I found only this:
USE [ScheduleDB]
GO
SELECT * FROM sys.objects WHERE object_id = OBJECT_ID('[dbo].[TTest]') AND type in ('U')
but it can only show structure modification date.

What’s the easiest way to check if a single value exists in a table column? I’m building a simple login page, and I want to get the username and check if it exists in my Users table. Here’s my SQL: SELECT UserID FROM UsersWHERE UserID = "admin" Could someone give me code to check for “admin” in my UserID column? Here’s some code I tried, using my SqlDataSource, but it returns an error “Could not load type 'System.Data.OleDb'” protected void Button1_Click(object sender, EventArgs e) { // Retreive the results from the SqlDataSource as a DataReader OleDbDataReader reader = (OleDbDataReader) SqlDataSource1.Select(DataSourceSelectArguments.Empty); // Read in the value if (reader.Read()) { } // Close the reader reader.Close(); } I don’t have to use the SqlDataSource, but originally thought it might be easier. I know how to use SqlDataSource to fill a whole GridView but this is different.
