Data Updation Based On Previous Data
Jun 10, 2008
Hi guys,
Here's something that I need to do. Might be pretty simple for you guys. :)
I have a table of Employees. All the employees work in some departments. So, I have a table of Department too. Employee table consists of details like EmpID, FirstName, LastName, SAP etc.
Dept table consists of TeamID, TeamNo.
Now, I have another table called as Emp-Team. This table basically maps the employees to the department by taking EmpID and TeamID. There's one more column in this table which is date. This date is required because when some person resigns (say today) then he won't feature in the headcount for July 08 but till June 08 he was there and this is how I maintain my history. e.g All the employees in the Emp_Team table have date as 01/06/2008 for this month. So, in future if I query for the employees who worked in June I will get this list.
Now, I want to copy all this data in the same table again and want to remove any people who have resigned. Their resignation status is in the Employee table, where you have their last working date as well. So, when I add all this data with date 01/07/2008 I want to remove any employees whose last working date is before that.
Can this be done or I have to change my design? In case it can be - How?
Thanks a lot! :)

I'm trying to only show yesterday's data based on a date that is stored as a varchar. I converted it to smalldatetime but I'm getting an error that says "Conversion failed when converting date and/or time from character string." I don't know how I have to alter the conversion.
Here is my code:
CONVERT(varchar(20), CONVERT(date, CONVERT(varchar(8), date_added), 112),110) = dateadd(day,datediff(day,1,GETDATE()),0)

I need to get previous month data in the table based on current date.
In case of execution of each month, the data for previous month should come with date as between
create table TestDate
(Sno Int,
Name varchar(100),
DateofJoin datetime)
insert into TestDate values (1,'Raj', '2/21/2014')
insert into TestDate values (1,'Britto', '6/12/2014')
insert into TestDate values (1,'Kumar', '5/14/2014')
insert into TestDate values (1,'Selva', '6/27/2014')
insert into TestDate values (1,'Ravi', '5/2/2014')
insert into TestDate values (1,'Gopu', '6/2/2014')
/*
if I execute in month July ( ie: today)
select * from TestDate where dateofjoin between 1-june-2014 and 30-june-2014
Result
5 Ravi 2014-05-02 00:00:00.000
3 Kumar 2014-05-14 00:00:00.000

I have a table with Million plus records. Due to Running Totals article, I have been able to calculate the Trial_Balance for all months.
Now I am trying to provide a Beginning Balance for all months and the Logic is the Beginning Balance of July would be the Trial_Balance of June. I need to be able to do this for multiple account types. So the two datasets that need to be included in logic is actindx and Calendar_Month.
For actindx of 2 and Calendar_Month of 2014-01-01The Trial_Balance_Debit is 19585.46 This would make the Beginning_Balance of actindx 2 and Calendar_Month of 2014-02-01 19585.46
I am trying to do some type of self join, but not sure how to include each actindx number differently.
Table creation and data insert is below.
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[TrialBalance](
[Trial_Balance_ID] [int] IDENTITY(1,1) NOT NULL,
[Code] ....

I need to create a function that replaces the data in a column with an 'X' based on the LEN of the data in the column. I created one that does a replacement, but it fills the column based on the max data length, and not the current length of the string or integer. An example of what I'm trying to accomplish.
Original data in a varchar(30) column:
thisisavalue
thisisanothervalue
thisisanothervalueagain
shortval
replaced with
xxxxxxxxxx
xxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxx
xxxxxxx
My current function is replacing the data like this:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

I need to periodically import a (HUGE) table of data from an external data source (not SQL Server) into SQL Server, with the following scenarios:
Some of the records in the external data source may not exist in SQL.Some of the records in the external data source may have a different value at different imports, but this records are identified univocally by the same primary key in the external datasource and in SQL Server.Some of the records in the external data source may be the same in SQL.
Due to the massive volume of the import, I would like to import only the records which are different from what I have in SQL Server (cases 1 and 2 above). In fact case 2 is the most critical.
I thought of making a query with a left outer join between the data in the external data source table (SOURCE) and the data in the SQL Server table (DESTIN). The join is done on the respective primary keys (composed keys of up to 10 columns) and one of the WHERE conditions will be that the value in SOURCE is different from the value in DESTIN.
The result of this query would be exactly what I need to import.
How to do this in SSIS??? I couldn't figure out how to join tables in different data sources yet.
In fact I cannot write a stored procedure to do that, since one of the sources is in a datasources not SQL Server.
I have seen the Lookup transformation in this article http://www.sqlis.com/default.aspx?311 but this is not exacltly what I want to do.
Another possibility is to use the merge join, but due to the sorting I believe its performances would be terrible!
Thanks in advance for your suggestions!

I'm in the middle of developing a Database for a hospital that measures its audits, inhouse operations, and finance. What we currently have and do everyday is collect data from a large database that is real time with patient data, progess, infomation, etc and dump it into a data warehouse that runs on TSI/Eclipsys. We run reports using a number of programs and dump it into Excel sheets that have charts, reports, etc. This Database for which I'm developing won't come soley from the TSI/Eclypsys source, but this is the only source thats updated regularly. I don't want to have in sync with TSI/Eclipysys in fear that every day when it updates data may be lost, not read, or worse won't be up date if there is a problem. My question is is it possible to run a query from Sequel Server 2005 that will take that data upon request using the reporing features on Sequel Server 2005. i.e. What if I need to run a report on measure B in department 12 from Jan 1-Feb 1, instead of being in sync, can I just write queries to take that information rather than double the data and take up twice the space and trouble. FYI, these datatypes rarely change in the TSI/Eclipsys data warehouse. This sure was long question and didn't intended it to be . Thanks for listening and hope to hear back.

I have a table called MasterSkillList which is a list of skills and attributes, eg: [Appraise, INT], [Bluff, CHA] etc
I have a table called Classes, which is a list of all classes available (and some details which are irrelevant), eg: [Fighter], [Assassin] etc.
I also have a table called ClassSkills which holds a list of classes and their applicable skills, eg: [Assassin, Bluff], [Assassin, Open Lock], [Fighter, Appraise], [Fighter, Bluff] etc.
What I have is a gridview which shows all my classes from the class table. i want to be able to select a class on that gridview and create a checkbox list of all available skills that are NOT allready associated with that class. Eg: assassin has bluff and open lock, so those two skills shouldn't appear on my checkbox list. So i want to show all the skill from the master skills list, excluding all the skills the selected class allready has.
Alternatively, It would be better if there was a way to display all the skills in existance on my checkboxlist and the ones that class allready has to be checked. Any suggestions?
Here's the query I have:
SELECT MasterSkillsList.SkillFROM ClassSkills INNER JOIN MasterSkillsList ON ClassSkills.Skill = MasterSkillsList.SkillWHERE (MasterSkillsList.Skill <> ClassSkill.Skill)
Edit:
I just added the following sql query, but when i run it i get no results even though it should show everything except 2 skills. Have I written it wrong?
SELECT SkillFROM MasterSkillsListWHERE (NOT EXISTS (SELECT Skill FROM ClassSkills WHERE (ClassName = @ClassName)))

Hello.
I am trying to implement Next and Previous buttons on a web page that uses CE as the database, and having some trouble getting the logic figured out. The data is unbound and I'm not returning it all at once, so paging through it an item at a time isn't possible. Because of the high volume, I was thinking I could pass in the record ID each time I need to retrieve a record and every time the user hits the next or previous button, I'll just requery for the record I need. Does that sound reasonable?
In my main page, I'm using the ViewState to store the record ID that I need to acquire. This part works--it gives me the highest ID number (so that I get the most recent record):
if (!IsPostBack) {
// Start out with the most recent record in the selected category. GetHighestConfessionID() will return
// the ID of the most recent confession.
ViewState ["ConfessionID"] = mySearch.GetHighestConfessionID (int.Parse(ViewState["Category"].ToString()));
}
Here's where the trouble comes in--I need to go to the next record in the database when the user hits Next, but I don't know how to do that. My big idea was to issue this command in the Next button:
ViewState ["ConfessionID"] = GetNextConfessionID (ViewState ["ConfessionID"]);
But I'm not quite sure how to increment/decrement my ConfessionID, since it's not guaranteed to be sequential (a record could have been deleted).
If the user hits Next, for example, I need to query for the next record ID, but I'm not sure how to do that since they're not necessarily sequential.
Is there a simple solution? I feel like I'm making a mountain out of a molehill.
Thanks in advance for any ideas.

I am working in sqlserver 2008 R2 and below is my sample research query. I am trying to get previous 6 months data.
WITH CutomMonths

SELECT UPPER(convert(VARCHAR(3), datename(month, DATEADD(MM, DATEDIFF(MM, 0, GETDATE()) - N, 0)))) Month
,DATEADD(MM, DATEDIFF(MM, 0, GETDATE()) - N, 0) startdate
,DATEADD(MM, DATEDIFF(MM, 0, GETDATE()) - N + 1, 0) enddate
FROM (
VALUES (1)
[Code] ...
Current output what i am getting:
Expected Output:
I found why the April month i didn't get the $20 because the startdate of my perks CTE '2014-04-03'. If it is '2014-04-01' then i will get the expected output.
But i should not change the the date on perks. How to neglect this date issue and consider the month instead to get the expected output.

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 am trying to code a rule at the moment which sets a value based on the value of the previous row. This is as far as I have got so far. I am trying to run it as a set based command and I believe I may need to make use of a numbers table.
Anyway the code is....
declare @data table
(ID int identity(1,1),
DeviceID int,
EventTypeID int,
EventID int)
[Code] ....
So the output is currently incorrect. Each DeviceID needs to have a ID assigned to the MIN(ID) which isn't yet in the code above. This ID has to be sequential across the full table and not dependent on ID.
Next the rule is coded in the case statement above.
So for each DeviceID, when the EventType goes from 1, 2 or 4, to 0 or 3, the following record after the 0 or 3 will have a new EventID. And conversely when the EventType goes from 0 or 3 to 1,2, or 4, the record that is the 1, 2 or 4 will have a new EventID.

We have a need to report on historical data when none exists in the database.
Create a tabular report rdl that is run on a regular schedule. This report run is saved as an Excel sheet that overwrites the previous run, which has the same name.
Report is designed to use two data sources--the database and and the previously run Excel sheet. The data is "merged" using the Lookup function thereby creating a new report that includes the history needed.

I'm storing records that contain a date/time data type. I am needing two links on a reports page (asp), the first should return all records for the current month and the second link should return all records for the last three months (including current month). I have no idea how to just sort by month.
I'm also not sure what to include here in this post to help you answer my question. On the form that is submitted initially the text field is named "txtSubmitDate" and in the database it's stored in a field called "submitdate" and is 8 characters in length.
I've tried:
'SELECT TODAY'S MONTH
SqlJunk = "SELECT * FROM eom WHERE MONTH(submitdate) = MONTH(GETDATE())-1"
'SELECT TODAY'S MONTH and the last 2 months
SqlJunk2 = "SELECT * FROM eom WHERE MONTH(submitdate) = MONTH(GETDATE()) OR MONTH(submitdate) = MONTH(GETDATE())-1 OR MONTH(submitdate) = MONTH(GETDATE())-2 ORDER BY submitdate ASC"
These are not working because it can't handle the change in year (going from january 2005 back to december 2004, etc).
Any ideas?

I am pretty new to SQL and facing difficulties with a current problem.
I have a list of customers and a sequence of events they have triggered . I know the sequence in which these events have been triggered and only want to increment a value when a new event is triggered (value to remain the same if the event is the same). I have come close to a solution with Dense_rank but the problem here is that the ranking doesn't reset if the same even previously triggered is triggered a bit later in the sequence. see below an example of current results and expected results:
Customer ID,Sequence ID,event,current result,expected result
1,1,A,4,1
1,2,A,4,1
1,3,B,3,2
1,4,C,2,3
1,5,A,4,4
1,6,A,4,4
1,7,E,1,5
1,8,D,5,6
2,1,B,3,1
2,2,C,2,2

i'd like to use ssis on a certain project but am concerned that one of my transformations needs lookup results to be based on actions taken on previous lookups and that the toolkit doesnt really offer something like that.
so, i have a dataflow whose first component extracts certain kinds of data from an xml document.
each row returned by the latter needs a lookup but the results of that lookup may dictate a certain kind of update. The next row's lookup may need to be influenced by the previous row's update.
So I think I have two challenges, 1) combining a lookup and update, 2) making sure the buffer architecture completes one lookup and update before the next lookup begins.

I need to write a t-sql query that will take the value of the previousrecord into consideration before calculating the current row's newcolumn value...Here's the situation...I have a query which return the following table structure...Full_Name Points----------------- ------------Name1 855Name2 805Name3 800Name4 775Name5 775Name6 741etc.... etc...I need to create a calculated column that tells me where the personranks in point position. The problem i run into is that in thesituation where two or more people have the same point value i need thecalculated rank column to display the same rank number (i.e. 4th orjust "4") I'm not sure how to to take into consideration the previousrow's point value to determine if it is the same as the current onebeing evaluated. If i new they were the same i could assign the samerank value (i.e. 4th or just "4").If any one has any insight that would be great.ThanksJeremy

I have a scenario to compare previous records based on each ID columns. For each ID, there would be few records, I have a column called "compare", We have to compare all Compare 1 records with Compare 0 Records. If Dt is lesser or equal to comparing DT, then show 0. Else 1
We always only one Compare 0 records in my table, so all compare 1 columns will compare with only one row per ID
My tables look like
Declare @tab1 table (ID Varchar(3), Dt Date, Compare Int)
Insert Into @tab1 values ('101','2015-07-01',0)
Insert Into @tab1 values ('101','2015-07-02',1)
Insert Into @tab1 values ('101','2015-07-03',1)
Insert Into @tab1 values ('101','2015-07-01',1)
Insert Into @tab1 values ('101','2015-06-30',1)
Insert Into @tab1 values ('102','2015-07-01',0)
Insert Into @tab1 values ('102','2015-07-02',1)
Insert Into @tab1 values ('102','2015-07-01',1)
select * from @tab1
1.) In the above scenario for ID = '101', we have 5 records, first record has Compare value 0, which mean all other 4 records need to compare with this record only
2.) If Compare 1 record's Dt is less or equal to Compare 0's DT, then show 0 in next column
3.) If Compare 1 record's Dt is greater than Compare 0's DT, then show 1 in next column
My expected result set should be like ....

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.
