Finding Workdays
Nov 27, 2007
Hi,
I have a table with 2 columns, a datetime column (date) and a bit column (workday)
This is a production calender. It's filled with all dates till 2020/12/31
I need a query to find the date of the n-th workday given a specific start date.
Using Sql Server 2000.
For example
Date Workday
--------------------
2007/11/01 0
2007/11/02 0
2007/11/03 1
2007/11/04 1
2007/11/05 0
2007/11/06 1
2007/11/07 1
Given the date 2007/11/03, the 2nd workday would be 2007/11/06
Thank's
Perry

This is one way you can add a number of workdays to a specific date and return a workday (monday-friday).CREATE FUNCTION [dbo].[fnAddWorkdays]
(
@StartDate DATETIME,
@DaysToAdd INT
)
RETURNS DATETIME
AS
BEGIN
RETURN@StartDate
+ CASE(@@DATEFIRST + (DATEPART(WEEKDAY, @StartDate) - 2)) % 7 WHEN 5 THEN 2 WHEN 6 THEN 1 ELSE 0 END
+ @DaysToAdd / 5 * 7
+ @DaysToAdd % 5
+ CASE WHEN (@@DATEFIRST + (DATEPART(WEEKDAY, @StartDate + CASE (@@DATEFIRST + (DATEPART(WEEKDAY, @StartDate) - 2)) % 7 WHEN 5 THEN 2 WHEN 6 THEN 1 ELSE 0 END) - 2)) % 7 + @DaysToAdd % 5 > 4
THEN 2
ELSE 0
END
END
E 12°55'05.25"
N 56°04'39.16"

Hi everyone,
I'm hoping someone can help me with some sql statements. I have a temp table that contains 30 dates that a student has missed in the last year. I also have a holiday table of when training was not available. I want to find out if there are 6 consecutive days missed excluding weekends and holidays (from the holiday table). I know this is some nasty looping statement but I can't get my brain around it.
I would like do this in a stored proc but I could use C# if necessary.
Thanks in advance, Jessica

I use the NETWORKDAYS(start_date, end_date,holidays) function in Excel and Access regularly. I'm trying to find a similar function in TSQL to use on Server2005. NetWorkDays allows me to calculate the difference between my ticket open and close dates while excluding weekends and holidays, (we are nice to our staff and let them off).
I'm trying to find an easy way to do this in TSQL without writing a large amount of code.
I will greatly appreciate any help.

Hello,
I am very new to SQL and I have an issue. We have a website that has pictures on the site. We want to take them down but the pictures are somehow tied into the database, they aren't on any of the servers. How can I find these pictures that seem to be somehow hard coded into the database?
Any help would be greatly appreciated.

I have a report that is grouped by week. The details of the week have the date, time interval (half hour), and the maximum value for that day. So in the example below I am showing the week of May 21st. Then I have all of the days of that week, sorted by date as requested, with the halfhour the maximum value occured in on that day. So Monday the 22nd has the maximum value for the week at 254 (and is highlighted in red). Where the ????? are below, I need to display '1400' which is the interval, but have not yet been able to figure out how to do this.
I tried the following expression:
=iif(max(Fields!MaxValue.Value) = Fields!MaxValue.Value, Fields!Interva.Value, "X")
but this only works if the first day is the maximum value.
5/21/2006

I have, say 4 rows for 1 client I want to find the date difference between two(or more) of the rows when the first has a true flag and the next does not
Row1 Date1,falseRow2 Date2,trueRow3 Date3,falseRow4 Date4,false
so I want to find the difference between Row2 Date2 and Row3 Date4I know I can loop through the rows but with 000's of clients each with x numbers of rows this will surely be very slow

I have a form where users can enter an appointment on this form some personal details are entered. I want the users to be able to write in a textbox the users surname. they will then press a button next to the textbox that will bring up a smaller screen displaying that users details :
SELECT * FROM Members where surname = (textbox1)
Alternatively the users can click the button and bring up a screen where the users can put the surname into a textbox and then bring up the users details this way.
I am not sure how to do this or how to select from the database where a field in the database is the same as the information put in to a text.
Is this possible? Thanks in advance Mike

I have a customer database with the following structure:
Dept ID (int)
Section (varchar)
I need to find only occurrences of a section (eg Admin) where the section name has a record in Dept 1,2 and 3 - only return the result if the record for Admin is associated will these depts.
Example Data:
Dept Section
1 Admin
1 Finance
1 Marketing
2 Admin
2 Sales
2 Marketing
3 Admin
3 Sales
3 Finance
The query would only return 'Admin' since this is the only Section that is represented in Departments 1,2 + 3.
I am not in control of the data design and can't create a bitwise field to achieve this.
tia,
Steve

Hi
My problem is a little tricky. I am trying to get the first distinct row(s) from a table where one column will have only a few differences, while a second is unique.
Now using "distinct" doesnt help as even though distinct(column1) may return only a few rows, because the next column is unique you will still have all rows returned.
How do I return only 1 row per distinct(column1) and drop the rest? What makes this so annoying is that all columns need to be returned, but only in accordance to distinct(column1)

Hi, sorry if this comes across as a stupid question, but i'm new to SQL. I have had a look on Google and on these forums but not found the answer..
I am running MS SQL 7 with a database containing around 130 tables.. i want to know if there is a query/command that i can type that will look through all the tables and tell me which ones reference a specified table (through it's key). Hope this makes sense! i've looked at some of the stored procedures but not found any that give me anything useful.
EDIT: Just so you are aware, i did not create this database, hence why i am not aware of the relationships myself, i have only just started working on it.
Thanks
Steve

I have a script that creates these spin off tables (used for lightning fast access) on a near daily basis. But it is possible the table does not exist for that day - in which the script need to check one day back - so on and so forth until finding the most recently created table.
The script I have written fails with overflow error.
I was hoping someone could tell me the correct syntax to accomplish this and also why i recieve this overflow error...
Code:
Dim str_SQL_Asset_1
daysBack = 1
tblFound = FALSE
Dim xbl_Holdings_date
Dim xMonth
Dim xDay
xbl_Holdings_date = date()
If Len(Month(xbl_Holdings_date))=1 Then
xMonth = "0" & Month(xbl_Holdings_date)
Else
xMonth = Month(xbl_Holdings_date)
End If
If Len(Day(xbl_Holdings_date))=1 Then
xDay = "0" & Day(xbl_Holdings_date)
Else
xDay = Day(xbl_Holdings_date)
End If
DO WHILE tblFound = FALSE
xbl_Holdings_Name = "xbl_Holdings_" & Year(xbl_Holdings_date) & "_" & xMonth & "_" & xDay
SQL_tblCheck_STR = "SELECT * FROM INFORMATION_SCHEMA.TABLES " & _
"WHERE table_name = '" & xbl_Holdings_Name & "' "
Set MM_checkCmd = Server.CreateObject("ADODB.Recordset")
MM_checkCmd.ActiveConnection = conn_str_ClientDB
MM_checkCmd.Source = SQL_tblCheck_STR
MM_checkCmd.CursorType = 0
MM_checkCmd.CursorLocation = 2
MM_checkCmd.LockType = 3
MM_checkCmd.Open()
IF MM_checkCmd.EOF Then
xbl_Holdings_date = (xbl_Holdings_date - daysBack)
daysBack = daysBack + 1
tblFound = FALSE
ELSE
tblFound = TRUE
MM_checkCmd.CLOSE()
SET MM_checkCmd = Nothing
END IF
loop
The goal of this snippet is simply to identify and set the value for the existing table name.
An example table name would be "xbl_Holdings_2006_12_10".
I could have posted this question in the VB forum but I would like to push as much of the work onto SQL as possible and also - this sort of operation is more likely to be required of a dba imo.

Hi,
I have the following code
SELECT
PR.WBS2,
SUM(CASE WHEN LedgerAR.Period = '200408' AND LedgerAR.TransType <> 'CR'
THEN Ledgerar.amount * - 1
ELSE '0' END) AS BillExt
FROM PR
LEFT JOIN Ledgerar ON PR.WBS1 = Ledgerar.WBS1 AND
PR.WBS2 = Ledgerar.WBS2 AND PR.WBS3 = Ledgerar.WBS3
WHERE PR.WBS2 <> '98' AND pr.wbs2 <> '9001'
AND pr.wbs2 <> 'zzz' AND pr.wbs3 <> 'zzz' AND
pr.wbs1 = '001-298'
GROUP BY PR.WBS2
It prints out:
Wbs2 BillExt
0141 0
0143 0
1217 20580
I want the code to return the wbs2 code '1217' because it has the highest amount in BillExt '20580'.
Can someone help me with this?
Thanks.

Hi, I am searching for the most easy SQL solution:
Lets say i have 500000 rows of cars in one table with 30000 different car ID's.
This table contains no keys, no date values, but I need the last row of these 30000 different cars. How do I get them without adapting table structure and without using cursors ?
Thx for reply.

I've done a search and I THINK I've got my head round this, but I'd be very grateful if someone could reassure me:
SELECT Email FROM List1 WHERE EXISTS (
SELECT Email FROM List2 WHERE List2.Email= List1.Email
) AND List1.Email <> '44'
That will give me every email address from list one that (a) appears in list two, and (b) isn't '44'. Right?
And to find all the emails from List1 that DON'T occur in List2 (and aren't '44'), I just put "NOT" in front of "EXISTS". Right?
Sorry for asking an obvious question but I'm having a real mental block here. :o

Our products exist in batches. These batches reference a warehouse.Each warehouse carries a set of 'roles'.Users on our system also carry 'roles'. Comparing user and warehouse roles tells the system what warehouses a user can access.
So, if:
WAREHOUSE1 has roles A + B
WAREHOUSE 2 has role B
WAREHOUSE 3 has roles A + C
and
USER1 has role A
USER2 has roles A + B + C
USER3 has role C
then
USER1 will have access to WAREHOUSE1 and WAREHOUSE3
USER2 will have access to all 3 warehouses
USER3 will have access to WAREHOUSE3.
What I need to do is write some SQL which allows a part number to be entered, and a list of batches for that part to be shown with a list of users who *CANNOT* access that part - because they do not have the relevant 'roles' for the warehouse(s) the part is in.
I can do the *opposite* of this quite easily (ie: show users who HAVE got access):
select distinct sb.batchnumber, ur.userid
from stockbatches sb
inner join warehouseroles wr on sb.warehouseid = wr.warehouseid
inner join user_roles ur on wr.roleid = ur.roleid where sb.partid = @part
order by sb.batchnumber, ur.userid
- it's a straightforward join between the warehouse and user roles, with a 'distinct' to eliminate any duplications.
Fair enough, but it's not what I want.
Using the role data above, with the following batch info:
Batch 1000, warehouse WAREHOUSE1
Batch 1001, warehouse WAREHOUSE2
Batch 1002, warehouse WAREHOUSE3
I actually want to get this results set:
Batch Users who can't use this batch
1000 USER3
1001 USER1
1001 USER3
I'm certain I can write the necessary logic programmatically in T-SQL, looking for single-statement SQL call?

So here is my dilemma:
We have licensed software from a 3rd party and we do not have the source code, nor can we do anything to change the database schema, write our own procs, triggers, etc.
With that said, we want to know which records in certain tables have been added or modified since a certain time (for example, in the past 24 hours). However, none of the tables has any datetime or timestamp columns on them for create date, update date, etc.
I tried to look into hacking thru DBCC log (dbname, 2) to see if that would help, what a mess. Using a tool like that from Luminent or Red Gate doesnt help either, because long term this needs to be automated if possible. Does anyone have any ideas on how to do this, or is the answer simply, "Sorry mate, you need to get them to allow you to change the database to add new columns and/or triggers". :)

Hi, I have two tables, Weekly and AverageEngTime. Weekly table has 14 columns, "Mon_Day,Mon_Night,Tue_day,....Sun_Night". AverageEngTime table has 15 columns, "Shifts,Mon_Day,Mon_Night,Tue_day,....Sun_Night". I have inserted "Average" as a value for column "Shifts" in AverageEngTime table. Now how do I find the average for each column in Weekly table and insert into AverageEngTime table in the respective columns, and in the row where Shifts = "Average".
I used the following codes to try but i receive errors at where statement.Please correct me. The expected output as below.
Shifts | Mon_day | Mon_Night | Tue_Day.....
Average | 5.2 | 10.2 | 15.2........
The codes that i tried..
declare @Weekday tinyint, @hour int
select @Weekday = datepart(dw,getdate()),@hour= datepart(hh,getdate())
if (@Weekday= 1 and (@hour>= 7 AND @hour<19))
begin
Insert Into AverageEngTime(Sat_Night) where Shifts = 'Average'
SELECT AVG(Sat_Night)
FROM Weekly
end
if ((@Weekday= 1 and @hour >= 19) OR (@Weekday = 2 and @hour < 7))
begin
Insert Into AverageEngTime(Sun_Day) where Shifts = 'Average'
SELECT AVG(Sun_Day)
FROM Weekly
