I've been searching the Queries Forum for help on this issue. I have a database that records loading records for a Taconite facility. Some days contain many records and on other days there are no records because of no loading activity. I create reports that group these loading records by each day, but I really need a quick and dirty report that just shows me the number of days in any month in which we had loading activity (records present). I have not figured out a way to create a query which counts the number of days in a month which contain records. I'm hope I'm explaining this well enough for someone to help me understand what to do.
I am trying to calculate the number of days between incidents.
If I have an incident that happened on the 10th August and another on the 15th August then this would be 5 days, the next incident occurred on the 28th August so that would be 13 days. The problem I am having is how to get access to use the latest date rather than the first date.
Is there any option to count the number or records relating to a specific field. Here is the details..The db is for a school and there is a tables for class and students. I am using a form to enter students details. I had created a relationship with these two tables. i am using a query to get the details regarding a specific class like classname, class teacher like that.. Is there any way to calculate the number of students in that specific class.
now i am using the query as follows
SELECT Class.* FROM Class WHERE (((Class.ClassID)=[Forms]![Class]![ClassID]));
I had created the relationship with the above two tables with classid as the primary key
Hello all. I need some help calculating the total number of records returned in a query anytime i run the query.
I have a form that creates an SQL statement and changes the querydef at runtime and displays the results in a listbox. I want to include on my form a percentage of the total records from the table based on the records returned in the query Ex. (5/10) so I can use this information on a report.
What I am trying to ultimately acheive is to calculate an attrition rate based on the number of (clients that leave in a given period / total new clients added in the given period )
I'm after some code as to how to count a number of records within a table, I then want to have this number returned into a variable so I can determine usages with it, e.g. If the value is < 1 and using conditional statements.
I have been tasked to create a DB for my unit. I have created a few DB, but I am a novice at best. I need a crosstab Query to count the number of records for each FY. The Army's FY is from Oct -Sep. I only need to show the the total number of record for the previous FY in a Report and on a form.
I'm creating a report for an imaginary "medical clinic's database", the intended function of which is described as follows: "Create a statistic that shows the total number of distinct drugs prescribed to a patient."
Where I'm at:
I've created a query called UniqueDrugs containing drug and patient info. The SQL is:
Quote:
SELECT DISTINCT Drugs.Drug_Name, Patients.[Patient _ID] FROM Patients INNER JOIN (Drugs INNER JOIN Prescriptions ON Drugs.[Drug_ID] = Prescriptions.[Drug_ID]) ON Patients.[Patient _ID] = Prescriptions.[Patient_ID] GROUP BY Drugs.Drug_Name, Patients.[Patient _ID] ORDER BY Patients.[Patient _ID];
The results of this query seem to be what I need. All I need is for the count formula that I use to return the number of distinct drug names there are that are related to a patient's ID.
I've created a report and I've put the following formula into a text box:
Where PID is the name of another text box in the report that contains the Patient ID that I want to compare to the drug names returned by the query.
However, this *always* results in #Error, no matter how I change the formula.I have been led to believe that syntax is not the issue, as the following formula worked as intended for a different task:
I have a form where a start date is inputted (Inputfrm , StartDate) and a form where the end date of the process is recorded (Inspectionfrm , EndDate) and these both record in the table InputTbl as StartDate and EndDate respectively.
I have created a union query which shows a list of all the dates where there is work recorded (WorkingDatesQry and the column of list of unique dates is "WorkingDate"), and as we run a highly varied schedule depending on time of the year and order numbers I cannot just use a query which says Monday-Friday or Tuesday - Saturday.What I am trying to do is to find the number of days between StartDate and EndDate where there is a date recorded in the WorkingDates query.
could someone please help me. ive tried all sorts of things and now im loosing the will to live. under the data protection act i have 40 days to produce requested files in a hospital. the problem is that my little database that has been working away for 2 years is not capable of flagging up any files that are gone over the limit.
i need to run a query that will bring up all files not completed in the past 40 days. or reaching the forty day limit.
ive tried <now()-40 or <date()-40 in the critieria of the date rquested field. ive also tried kicking the machine when my boss isnt looking. that didnt work either.
I would like to count the number of working days between two dates, NOT the calendar days, if the workers only work Monday thru Thursday. I know we could use the DateDiff function, but HOW do I count excluding Fridays, Saturdays, Sundays?
I am looking to do a calculated field. Not sure what is the best way to do this, but I would like to have a dates in a table with all of our employees that has what date they started with the company. From that I want to know not how many days they have been with the company, but just the years.
So if I have been with the company 364 days, it should only show up as 0, and if I have been with the company for 365, it will read 1. I would like this to be in a query somehow. We use the number of years they have been with the company for their pay, and need it to be years, and not days.
I have 2 dates that I need to count between. Easy enough just use the datediff right? Nope cause it won't count just the 5 workdays. I researched and found that the "w" in the function doesn't work the way I need it to. I found lots of code to make a module that will do it for me and they all include having a holiday table. Right now I don't need a holiday table I just want the simple dates in between.
I have a report due the first of each week in which I need the cases open and cases closed for the previous week, the week two weeks prior and the 2007 and 2006 year to date on two different types of cases. I have a case management table with a field for Type of Case, date assigned and date closed that I uses in my queries. Presently I have two query, one that generates only Type 1 cases from the Case Management Table and another for Type 2. I then use the Type 1 Query in another query that limits the results for Type 1 cases to those opened last week, one for those open two weeks ago, one for 2006 YTD and one for 2007 YTD. In these 4 queries I have one field [Type of Cases] and I have the query count. I then do this for Type 2 cases and then go through the whole process to do Closed Cases. All my queries have criteria to automatically filter the dates to the time periods mentioned above. I then have one report query that I put all the number in for my report. This query has 16 fields with the numbers for each period, last week open and closed, 2 weeks open and closed, etc. I then generated a report that takes these numbers from my report query and puts it in a report format automatically. As you can imagine this takes some time to go through each query to generate these numbers, so I was wondering how I may do this differently. Also, I have experienced a problem when a field produces no records I get a blank sceen with nothing under the Count of column and get the same thing for my report. How can I fix this.
I need to work out a couple of calculations, the number of days between an engineer starting and finishing a project, the number of days between the project being put on the database in the first place and being completed by an engineer and finally, the difference between these. These maybe simple, but I have no idea tbh (still new to access).
I have a form with the date it was added onto the database, and the engineer fills in the date started and date finished as it happens.
These run off of 2 tables BookingIntbl and TechnicalServicestbl
[BookingIntbl].[Date], [TechnicalServicestbl].[Date Started] and [TechnicalServicestbl].[Date Finished]
I have then got the fields, 'Days with Engineer', 'Days in Repair Centre' and 'Day Difference' for the answers to be displayed.
In a database, I have the following date fields that I use to track projects that start and stop.
START1 STOP1 START2 STOP2 START3 STOP3
Is there a way I can use a query to calculate the total days the project was worked on? For example if I enter 1/1/06 in START1, 1/10/06 in STOP1, 2/1/06 in START2 and 2/15/06 in STOP2, 3/1/06 in START3 and 3/30/06 in STOP3, I need to calculate the total days. I need it to work regardless if there are 3 start/stops, 2 or just one start/stop.
I imported an large Excel file with a date column consisting of 3 different date formats and need help on a query to extract the number of days. Examples of the date on that column:
