I've got two columns, one with a year (e.g. 2013, 2014) and one with a number of the month (e.g. 2, 3, 4).
Is there code that I could use to bring back the previous 12 months from my selected month? So if I selected my year as '2014' and my month as '9', I'd like to bring back the results going back to year '2013' and month '10'.
Is that possible without having a datetime field?
This should be possible. I would do this with "month" arithmetic. For instance, to get all dates since 2013-10, for selected month 2014-09:
select t.*
from table t
where year*12 + month >= 2014*12 + 9 - 12;
I have a yearly chart that it broken down into the 12 months Jan - Dec. The report contains various parameters including a yearly dropdown that changes the chart and report.
This all works fine within the first report.
The problem is that I have set up an action on the chart to go to a second report with a monthly breakdown, so my question is how can I pass the monthly value from the first report to the second?
The monthly report has an additional date from and date to parameter, so for the month of January it would need the values: Date From: 01/01/2010 and Date To: 31/01/2010 for example.
Thanks in advance.
Since you have the year and month integer values, you can construct the start and end dates to pass to your other report using expressions.
The start of the month will be:
=DateSerial(Fields!Year.Value, Fields!Month.Value, 1)
Where Year and Month are the integer values from the Chart/Dataset.
The end date is a bit more complicated; since the day part can be 30/31, etc, but we can just add one month to the above expression to get the first of the next month, then go back a day:
=DateAdd(DateInterval.Day
, -1
, DateAdd(DateInterval.Month, 1, DateSerial(Fields!Year.Value, Fields!Month.Value, 1)))
This way your drillthrough report can get its date based parameters and you don't need any changes to your dataset/parent report.
I have a date column in which the dates are re-curring every year. I'm only interested in the month really, but I can't just put the month number as the high and low value for the gant chart. Is there any way I can format the column? Any suggestions would be awesome.
The gant chart currently is taking the whole date and is working fine, but like I said it goes out to the next year.
Figured it out. So the DATECOLUMN I had was formated as such:
Example: 2013-01-01 00:00:0.000
In order to put in the GANT(RANGE) CHART in the series property, under values, I formated the Top Value and Low Value as =MONTH(DATECOLUMN) using the expression option.
Then for the Horizontal Axis Properties I set the Interval to 1 and Interval Type to Number. And There you have it Monthly time spans with only the Months 1 - 12 showing.
I must also note that I only had one time recorded. So I just did Top Value as: DATEADD(MM,1,DATECOLUMN) In Order to get the right time span in my dataset Script.
Which date format would u like to display in your chart.
If (month with year) like 'Sep 2013'
use this date format for the same.
SUBSTRING(CONVERT(VARCHAR(11),getutcdate(), 113),4,8)
I just don't know how to go about this.
I designed a program that uses MS Access as its database. I have a field for month and year (the field data type is text) where user can register details. The program will register the month and year the user have chosen e.g month= September, year=2011.
My problem now is how to chose a range of data to view by the user using the month and year as a criteria e.g the User may want to view data range from (September 2011 to July 2013).
I couldn't figure out even how to try. Help will be highly appreciated.
Perhaps you could change your application logic to store the month and year as their respective numbers rather than text and change the field data types to numeric.
You could then construct a DateTime object from them, for example September would be 9 and you could use code like the following:
var startDate = new DateTime(year, month, 1); // get year and month as integers from database, uses the first as the date
var endDate = new DateTime(year, month, 10); // change the date but keeps the month and year the same
var endDate2 = startDate.AddMonths(1); // adds 1 month to the date
Alternatively, you could try using a calendar control to allow the user to select two dates instead of building it from a number of fields. Depending on what you are using this could be achieved a number of ways, for example in ASP.Net or WPF you could use two calendar controls and just use their SelectedDate properties as your range.
A range is from a startpoint until an end point. For the startpoint you can add automatically the first of Month. For the endpoint is it more complicated because there is no fix endpoint. What you can do is following:
Write an array that contains for each month the days (e.g. 30 or 31). Except for Febrauary there is a fix pattern.
for Febrauary use the selected year to check is the year a leap year or not. If not add 28, else add 29.
After that create the date string for your SQL:
Startdate 1.9.2011. Do for the entdate the same.
After that, I think you can use the keyword between in your SQL query.
You can assume that everything is entered on the first day of each month. I would pull the information using a query to the database.
select * from [tablename] where DateSerial([colYear], [colMonth], 1) between DateSerial([fromYear], [fromMonth], 1) and DateSerial([toYear], [toMonth], 1)
In this question are some ways to do this:
First. Filter the dates in a range assuming that you use a date like '07-12-2012'
i.e. September 2011 to July 2013
Where DateColumn > '09-01-2011' and DateColumn < '07-31-2013'
OR
Specify a Date and a Year
Where month(DateColumn)='1' and year(DateColumn)='2016'
Note:
There are many ways to do this.
You can Manipulate your statement depending on your desired output.
I'm creating a report in MS SQL Server Reporting Services and need to set the default Start and End Date report parameters to be the first and last dates of the previous calendar month and need help.
The report is generated on the 2nd calendar day of the month and I need values for:
Previous Calendar Month
- first day
- last day
I've been working with DateAdd, but have not been successful at creating an Expression (in VB.NET as I understand it). I would really appreciate any help you can give me!
Randall, here are the VB expressions I found to work in SSRS to obtain the first and last days of any month, using the current month as a reference:
First day of last month:
=dateadd("m",-1,dateserial(year(Today),month(Today),1))
First day of this month:
=dateadd("m",0,dateserial(year(Today),month(Today),1))
First day of next month:
=dateadd("m",1,dateserial(year(Today),month(Today),1))
Last day of last month:
=dateadd("m",0,dateserial(year(Today),month(Today),0))
Last day of this month:
=dateadd("m",1,dateserial(year(Today),month(Today),0))
Last day of next month:
=dateadd("m",2,dateserial(year(Today),month(Today),0))
The MSDN documentation for the VisualBasic DateSerial(year,month,day) function explains that the function accepts values outside the expected range for the year, month, and day parameters. This allows you to specify useful date-relative values. For instance, a value of 0 for Day means "the last day of the preceding month". It makes sense: that's the day before day 1 of the current month.
These functions have been very helpful to me - especially in setting up subscription reports; however, I noticed when using the Last Day of Current Month function posted above, it works as long as the proceeding month has the same number of days as the current month. I have worked through and tested these modifications and hope they help other developers in the future:
Date Formulas:
Find the First Day of Previous Month:
DateAdd("m", -1, DateSerial(Year(Today()), Month(Today()), 1))
Find Last Day of Previous Month:
DateSerial(Year(Today()), Month(Today()), 0)
Find First Day of Current Month:
DateSerial(Year(Today()),Month(Today()),1)
Find Last Day of Current Month:
DateSerial(Year(Today()),Month(DateAdd("m", 1, Today())),0)
Dim thisMonth As New DateTime(DateTime.Today.Year, DateTime.Today.Month, 1)
Dim firstDayLastMonth As DateTime
Dim lastDayLastMonth As DateTime
firstDayLastMonth = thisMonth.AddMonths(-1)
lastDayLastMonth = thisMonth.AddDays(-1)
I'm not familiar with SSRS, but you can get the beginning and end of the previous month in VB.Net using the DateTime constructor, like this:
Dim prevMonth As DateTime = yourDate.AddMonths(-1)
Dim prevMonthStart As New DateTime(prevMonth.Year, prevMonth.Month, 1)
Dim prevMonthEnd As New DateTime(prevMonth.Year, prevMonth.Month, DateTime.DaysInMonth(prevMonth.Year, prevMonth.Month))
(yourDate can be any DateTime object, such as DateTime.Today or #12/23/2003#)
in C#:
new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).AddMonths(-1)
new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).AddDays(-1)
I was having some difficulty translating actual VB.NET to the Expression subset that SSRS uses. You definitely inspired me though and this is what I came up with.
StartDate
=dateadd("d",0,dateserial(year(dateadd("d",-1,dateserial(year(Today),month(Today),1))),month(dateadd("d",-1,dateserial(year(Today),month(Today),1))),1))
End Date
=dateadd("d",0,dateserial(year(Today),month(Today),1))
I know it's a bit recursive for the StartDate (first day of last month). Is there anything I'm missing here? These are strictly date fields (i.e. no time), but I think this should capture leap year, etc.
How did I do?
I was looking for a simple answer to solve this myself. here is what I found
This will split the year and month, take one month off and get the first day.
firstDayInPreviousMonth = DateSerial(Year(dtmDate), Month(dtmDate) - 1, 1)
Gets the first day of the previous month from the current
lastDayInPreviousMonth = DateSerial(Year(dtmDate), Month(dtmDate), 0)

This one will give you date no time:
=FormatDateTime(DateAdd("m", -1, DateSerial(Year(Today()), Month(Today()), 1)),
DateFormat.ShortDate)
This one will give you datetime:
=dateadd("m",-1,dateserial(year(Today),month(Today),1))
Dim aDate As DateTime = #3/1/2008# 'sample date
Dim StartDate As DateTime = aDate.AddMonths(-1).AddDays(-(aDate.Day - 1))
Dim EndDate As DateTime = StartDate.AddDays(DateTime.DaysInMonth(StartDate.Year, StartDate.Month) - 1)
'to access just the date portion
' StartDate.Date
' EndDate.Date
