Advanced DateDiff Logic/Code Needed

Jan 5, 2007

I am trying to figure out how much coverage (supervision time) an employee has based on their managers schedule.

Example
Name: Employee, SundayStart: 9 AM, SundayEnd: 5 PM
Name: Manager, SundayStart: 8 AM, SundayEnd: 4 PM


############# 8 AM |Covered Time| 5 PM
Employee ##########|------------|-----
Manger ######------|------------|


Employee is covered for 6 hours on sunday.

Anyway to figure this out? This is what I have so far. Sorry, but im in access 03.


SELECT tblCAESchedule.Name, tblCAESchedule.Title, tblCAESchedule.SunStart, tblCAESchedule.SunEnd,
IIf(DateDiff("n",[tblCAESchedule].[sunstart],[tblCAESchedule].[sunend])>=1,DateDiff("n",[tblCAESchedule].[sunstart],[tblCAESchedule].[sunend]),DateDiff("n",[tblCAESchedule].[sunstart],[tblCAESchedule].[sunend])+1440)/60 AS SunHours,
tblSupSchedule.Name, tblSupSchedule.SunStart, tblSupSchedule.SunEnd,
Abs(DateDiff("n",[tblCAESchedule].[sunstart],[tblSupSchedule].[sunstart])/60) AS StartDif,
Abs(DateDiff("n",[tblCAESchedule].[sunend],[tblSupSchedule].[sunend])/60) AS EndDif,
Abs(DateDiff("n",[tblCAESchedule].[sunstart],[tblSupSchedule].[sunstart])/60)+Abs(DateDiff("n",[tblCAESchedule].[sunend],[tblSupSchedule].[sunend])/60) AS ShiftDif
FROM tblCAESchedule INNER JOIN tblSupSchedule ON tblCAESchedule.Skill = tblSupSchedule.Skill
WHERE tblCAESchedule.Skill = "Sales"

Upsert Logic Needed

Dec 30, 2007



My organization is required to ETL millions of rows of medical insurance claims data per month into our data structures from many different external systems. The data structures vary tremendously between the different source systems.
We need to develop an efficient "upsert" algorithm: e.g. when a new row arrives from a particular source system determine:
a: does a row with an identical unique natural key (often a composite) already exist in our system?
b: if "a" above is true, is any non-key data in the newly arrived row different from the existing row with the same key?
c: depending on the results of test a and b above, perform either an insert or update.

So we need to develop an internal "upsert" logic solution. We also want to have a solution that will support a generalized solution as early as possible in the data processing.
Therefore, we are considering applying two identical MD5 hashing algorithms (probably C or C# extended stored procs) to each incoming source row (and a one time generation of the two hashes for all legacy loaded rows). One hash will be created from the unique natural key for each row, and one will be created from all the remaining columns in the row. Together these two MD5 hashes should allow us to perform comparisons on all newly arrived vs. previously loaded data, and reliably determine results of tests "a" and "b" above.

This approach also supports the requirement that the code that performs the upsert logic be generalized as early as possible for all different source systems, as the actual test logic will be identical for all source data and independant of the custom logic used to generate the MD5 hashes for each unique source structure.

Is there a better way? How do others approach this problem? What kind of performance impact can be expected from the xp calls?

Thanks!

Complex Date Logic - Help Needed

Sep 21, 2004

This concerns eligibility healthcare information. A member can have multiple rows in the table showing they are eligible for different date ranges with different health plans. eff_date and term_date are the fields in this table. Term_date can be NULL.

I need a WHERE statement that shows members
1) eligible between 1/1/2004 and 8/15/2004

(term_date is null or term_date >= '8/15/2004')
and eff_date <='1/1/2004'

2) members are allowed only one gap in this timeframe of up to 45 days. *NEED HELP

3) a gap of 1 day should not be counted as a gap in enrollment. *NEED HELP

Any help on #2 and #3 would be appreciated.

SQL Query JOIN Needed? Too Advanced For Me

Sep 5, 2006

THIS LOOKS LIKE A LOT BUT I JUST WANTED TO GIVE ALL INFORMATION NEEDED FOR YOU TO EASILY ASSIST ME.  I am not good with SQL so please bare with me. I will give a dumbed down table for us to work with:timestamp          -   DATA1 - DATA2 - MAXVALUENEEDED - DATA32006/8/12 12:00       123         125             1289                      121 2006/8/12 12:05       124         128             1291                      1232006/8/15 12:00        130        128              1190                     1242006/8/15 1:00          131        127             1196                      123  The columns labeled DATA do not really matter.  The only important ones are timestamp and MAXVALUENEEDED but I do need the query to return all columns. What the query has to do: The query needs to find the MAX of MAXVALUENEEDED for a given DAY.  Example Output- 2006/8/12      124   128   1291   1232006/8/15      131   127   1196   123As you can see the MAX values were grabbed for each given day and the unique records were returned on a per day basis. My current SQL Query is:  SELECT CONVERT(varchar, timestamp, 101) AS Time, CONVERT(int,LV50AEPM_AMPS_A_VAL0) AS AMPS_A, CONVERT(int,LV50AEPM_AMPS_B_VAL0) AS AMPS_B, CONVERT(int,LV50AEPM_AMPS_C_VAL0) AS AMPS_C,
CONVERT(int,LV50AEPM_KVA_TOT_VAL0) AS KVA_TOTAL, CONVERT(int,LV50AEPM_KW_TOT_VAL0), CONVERT(int,LV50AEPM_VLL_CA_VAL0), CONVERT(int,LV50AEPM_VLL_BC_VAL0), CONVERT(int,LV50AEPM_VLL_AB_VAL0)
FROM Table_1 T1
WHERE CONVERT(int,T1.LV50AEPM_KVA_TOT_VAL0) = (SELECT MAX(CONVERT(int,T2.LV50AEPM_KVA_TOT_VAL0)) FROM Table_1 T2 WHERE CONVERT(varchar,T1.timestamp,101) = T2.timestamp)
ORDER BY Time ASC The problem is it only returns the max value for one day instead of all days.  Can anyone help me correct this?  Thanks in advance for your help.

Advice Needed: Where To Put ADO Code

Jan 5, 2007

I need some advice on a project that I am working on...
First, here is what I am trying to achieve:  A Web Form with two controls:  A DropDownList with two items added at design time (Fruits and Vegetables) and an empty ListBox.  When the user chooses a "category" from the DropDownList, the ListBox will be populated with a list of either "Fruits" or "Vegetables" retrieved from a SQL database.  (Note:  Since the data in the SQL database must be converted and formatted programatically, simply databinding the ListBox will not work here.)
I believe that I can do this with the following code (stolen from an MSDN article):'Create ADO.NET objects.
Private myConn As SqlConnection
Private myCmd As SqlCommand
Private myReader As SqlDataReader
Private results As String

'Create a Connection object.
myConn = New SqlConnection("Initial Catalog=Northwind;" & _
"Data Source=localhost;Integrated Security=SSPI;")

'Create a Command object.
myCmd = myConn.CreateCommand
myCmd.CommandText = "SELECT FirstName, LastName FROM Employees"

'Open the connection.
myConn.Open()

myReader = myCmd.ExecuteReader()

'Concatenate the query result into a string.
Do While myReader.Read()
results = results & myReader.GetString(0) & vbTab & _
myReader.GetString(1) & vbLf
Loop
'Display results.
MsgBox(results)

'Close the reader and the database connection.
myReader.Close()
myConn.Close()
  Now here is the part that I am not sure about:  Is the FormLoad event the best place to put this code?  If I do, is this not a lot of overhead (creating, opening and closing a connection) everytime there is a page refresh/PostBack?   Would I be better off putting this code in the DropDownList SelectedIndexChanged event?  Although that seems like it could make the process of selecting a category take a fairly long time.
Finally, if the is a better way of doing this, I am certainly open to suggestions.
All advice is greatly appreciated.

Datediff Or MAX?

Mar 9, 2004

Hello,

My string is:

SELECT weight FROM progress WHERE dateInput = (SELECT MAX(dateInput) FROM progress) AND memberID = 1

The problem is that the MAX dateInput doesn't belongs to memberID 1. It belongs to memberID 2. What I want is that I wanna choose the MAX Date of memberID 1. I thought of maybe using datadiff function. But I don't know how to make the datediff statement. Maybe I can write the datediff statement whereby the least datediff between the dateInput and getdate() will be the row I want. I really appreciate the person that helps me this problem... Thanks 1st of all!

DateDiff

Apr 15, 2004

I am trying to select records from whatever the current date would be and 12 months before whatever the current date is. How would I go about doing this. The table that I am trying to do this with has a year column and a month column.

I was playing with the date diff function, but I can only get dates from the specified date range. I need it to be where if I run it tomorrow, it will get that day and everything within the last 12 months.

DATEDIFF?

Apr 25, 2008

I need to get a listing of all persons who are atleast 18 years of age. A date of birth field in the database is in this format:

4/25/2008 12:00:00 AM

My solution would be where the difference between the current date and the dob is >= 18.

I tried...

select * from table where datediff(yy,dob,getdate)) >= 18.

But this only seems to subtract the years and ignore the days/months, which I need. Could anyone provide the syntax I need?

Help is appreciated. Thanks.

Hi there i am using the datediff funtion but it does not seem to be inclusive of the two dates eg

i know i could do
SELECT DATEDIFF(day, s_Date, e_date)+1 AS NumberOfDays,*
FROM weekendtest

but i was just wondering if there some other function i should use that would be more appropriate

Help With Converting Code: VB Code In SQL Server 2000-&&>Visual Studio BI 2005

Jul 27, 2006

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:

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")

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!

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.




Thanks in advance.

Datediff Problem

Jan 12, 2007

I'm trying to use the same select statement I used in classic SQL, but it isn't working.  I get a "The server tag is not well formed." error.
I'm trying to return all the records where the date in a particular field are over 60 days old.  My select statement is:
"SELECT [ReNewAd], [Male or Female], [File2], [PHOTO], [First Name], [Last Name], [City], [State], [NewAd] FROM Members Where ('NewAd' IS NOT NULL AND (DateDiff('d', [NewAd], '" & Now() & "') <= 60)) order by [NewAd] Desc"
I've been looking through the datediff posts, but I'm not making any sense of what I'm reading.  Can anyone see what I'm doing wrong?
Thanks, Diane

I tryied to make a stored procedure (in fact i maked a lots of them, for 1day 3 days 1 week 1 month), but i have a problem with that DateDiff and DateAdd
Here is what i tryied CREATE PROCEDURE LastAdded_2monthsAgo

AS

SELECT Pictures.ProductID, Pictures.Name, Pictures.Description, Pictures.DateAdded
FROM Pictures
WHERE (DATEDIFF(month, Pictures.DateAdded, GETDATE()) >= 0) AND (DATEDIFF(month, Pictures.DateAdded, GETDATE()) <= 2)

Using DateDiff Function For Age

Nov 12, 2007

Hi,I'm using the datediff function to display the ages of the users in my database. However the age rounds up once they are 35.5 etc...I could create another function which works similar to the DateDiff function, but use math.floor to always round down, but I need to use this function in a SQL statement WHERE clause. Is there any way around this?Thanks,Curt.
