Queries :: How To Count Number Of Times Data Appears In A Field
Sep 23, 2013
How to count the number of times that the data appears in a certain field (which is [Ema!l]). I have a list of ema!l addresses and I want to find out whether that ema!l address has appeared once, twice or more. I want to add this as a field in a query. I don't want to delete it or anything because it's perfectly fine for the ema!l address to appear more than once, I just want to be able to identify when the ema!l address has already appeared.
If I was using Excel I would use a Countif function to count how many times the data in the specified cell appears in the whole column, and that would give me the number. I'm not use to the language of Access so I can't figure out how to achieve this.
I tried adding a Total row to the grid in the query and then changing the total to 'count' but this just returned 1 for every row.
I have a log in table that counts every time a user logs onto the database. Each time a user logs in it adds another entry to a table.
I have built a query to display the user name and date of log in so I could display this information in a report. The report is now getting rather long, and I am looking for a way to display each users name and have the total number of times they have logged in, not display each time they have logged in separately.
The Query has two fields "Agent Name" and "Logger Date"
The report displays the data as follows
Agent Name Logger Date User 1 26/5/13 User 1 26/5/13 User 1 27/5/13 User 2 28/5/13
What I would like to do is have a report listing each users name, with a column showing how many times they have logged on. e.g.
I want to use to count how many times a record is displayed in the period and lesson field, in another table, so that this data can be used to show how many people are attending a class. e.g how many times people are attending art 1, by counting how many times art one appeared in the first table.
I'm working with a table of bird survival data I am trying to summarize in a query. I've got a bit of a roundabout way to achieve my goal, but I'm curious if there is a simpler approach.
Background : In my table, each row represents a day I check a given nest and includes a [Nest ID] (not unique, multiple visits to each nest), a [visit ID] (auto numbered, so it's a unique value for each visit at each nest), the calendar day I visited a nest [Date], and [Survive] (1 or 0) depending on whether a nest survived or failed.
I'm trying to convert this detailed table into one that is more concise. Instead of each visit to a nest being a row, each nest becomes a row with 4 fields: The Nest ID, the minimum date (the day I found a nest), the last day a nest was checked (Max[Date]), and the last day a nest was checked alive (essentially max date where survival=1).
My current solution is to run 3 separate queries. The first queries the max date where survival=1, the second queries the max and min dates regardless of any other criteria, and the third brings both queries together.
I am curious if there is a way to create the same final product in a single query rather than doing multiple ones as I have done?
I have 2 tables...a lookup table with possible responses (i.e. yes, no, don't know) and the second with 8 fields that contain the values selected from the first table. Tables are related one-to-many. I need to count the number of times each of the responses shows from the lookup table shows in each of the fields in the main table. Have tried to query with the lookup field set to "group by" and each field set to "count".
I have a report that i can order through buttons on report or openargs. Is it possible to get a field that would count the number of time an item appears i.e., if I sort it by employee, it would count how many times each employee is on the report, if i sort it by TypeOfMalfunction, it would count how many times each appears.
I have 2 tables (person / merit) currently the merti table has 4 fields (MeritID, PersonID, Issuer, Type) I'm trying to count the the Type field 7 times, once of each type (MC/MI/MN/MP/MS/MV) and once to count a grand total.
I want to produce a query to use in a mail merge that will list the total for each merit type and one grand total.
I've been trying a few different things including sub queries but I've not managed to get the query to produce a single record that counts each individual type.
What I would like to do is have a field in a given record increment itself every time that record is selected. For example, say you have a table that stores items in the inventory: each item has a times_search_for_field.
Now, lets say a user runs a search which results in the following SQL:
SELECT * FROM Inventory WHERE experation_date=Today();
Now I want to have every record returned by that SQL statement increment it's times_search_for_field incremented by one. I'm just looking for the most efficiant way to do this.
I know I chould just have my asp .net code loop through the results and call an SQL UPDATE statement for each record, but it seems there should be a more efficient way of doing this.
I'm trying to generate a query that can be used for a pareto chart (Bar Chart shows the count of a defect and a line chart as a second axis counts the cumulative percentage)
I've grouped my data, and sorted the Count of each time the record appears but I cant get my head around working the cumulative percentage. My datasheet currently looks like this:
Reason Count Per Expr1 A 35 47.9 Random Numbers B 11 15.1 " C 10 137 " D 9 12.3 " E 7 9.6 " F 1 1.4 "
I have one field containing a couple of 6 digit codes and would like to count the number of codes in the field and write the number to a calculated field. Each code is separated by a comma and a space. How can I count the no of comma within the field?
The field SECL DDI has the users phone number unfortunately over time these have been entered in different formats so there are 5 digits, 6 digits, 7 digits etc...Can I run a query that counts the number of digits in each filed and then tell me how many of each exist
I am starting to create a resourcing database that needs to be able to work with dates and times and perform calculations on them.
I need to work out the number of hours. I have two date/time fields Day_Start_Time and Day_End_Time. I want to calculate the difference between the two in hours and then multiply by the number of working days.
I tried this: Number_Of_Hours: DateDiff("hh",[Day_Start_Time],[Day_End_Time])*[Number_of_days]
I have windows 7 access 2013, I had a query made, and wanted to add fields to it, so i went into the SQL and added several fields. Only the first one i entered didn't work and on the query is called "Expr1003" when in datasheet view. Its right in layout view, and even when i tried adding the same field in layout view, it made it "Expr1004". spelling is correct, in both source table and query, i don't know why this field doesn't work especially when the others did.
I would like to do a loop but never done one before, basically i want to copy the current record by the number of times specified in a quantity field
So if the quantity field in the record says 5 then copy that record 5 times (I have managed to create the copy and paste code but dont know how to make it do it 5 times
Running Access 2010 and developed this query to filter out data from a table between times on 2 dates (day before report run and day of report). Covers data from a shift that carries over to the next day.Trouble is, the PC i developed on still operates the query as expected. However, on the PC the database resides (not networked just stored) and operates, the query brings up no data at all unless I remove the Time filtering.
This PC used to operate correctly up until early this year (about 18 months operated correctly) when the PC was replaced due to failure. Access version is the same and I am at wits end to what the cause is. Here is what my query looks like:
Quote:
SELECT Breakdowns.BreakdownDate, Breakdowns.Time, Breakdowns.Shift, Breakdowns.Downtime, Breakdowns.Equipment, Breakdowns.Conveyor, Breakdowns.Fault, Breakdowns.Stopper, Breakdowns.Gate, Breakdowns.Dolly, Breakdowns.Carrier, Breakdowns.FaultType, Breakdowns.Comments, Breakdowns.Tradesman FROM Breakdowns WHERE (((Breakdowns.BreakdownDate)=Date()) AND ((Breakdowns.Time) Between #00:00:00# And #6:29:00#) AND ((Breakdowns.Shift)="Night")) OR (((Breakdowns.BreakdownDate)=Date()-1) AND ((Breakdowns.Time) Between #22:30:00# And #23:59:00#) AND ((Breakdowns.Shift)="Night"));
I have two tables, Students and AttendanceRecords.
Students just has studentID and studentName
AttendanceRecords has AttRecID, studentID, presence, thedate
I'm looking to create what looks like an Excel grid, with the last 10 days as columns and the student names as rows. All the cells in middle will be filled with the values of 'presence' for that student/day (e.g., P for present, A for absent).
Here's something I'm currently considering.
-I could make 10 queries, each using LEFT JOIN to connect studentName with presence & thedate on studentID, varying the 10 queries only in that 'thedate' will have a criteria of Date() -1 , Date() -2 , etc. -If I'm understanding it correctly, I'll then have 10 tables, each containing 3 rows -- student name, presence, and the date (with each table having only 1 date repeated throughout). -I could then join those 10 queries together on studentName, theoretically resulting in 1 big table with all the student names and the corresponding presence values for the last 10 days
If I do that, I could make a form in Continuous view and have each row show the studentName and 10 text boxes closely bunched up with presence values.
That seems very inefficient? Making 10 queries separately and then manually merging them seems redundant.
Also, now that I think about it, will the final product end up being read-only, or if the user changes one of the presence cells will it update the corresponding record in AttendanceRecord?
I've created a report and report has the same number of pages as the number of records that it's displaying.
If there are two records, the report has 4 pages...the first 2 are the actual report and then the other 2 are a copy. If there are 3 records, the report would have 3 copies (...6 pages).
Any idea how to change this so that I have only one copy of the report?
I just can't seem to get this one to work right. I've got the following query. I need to count the number of Null dates or show zero if there are no Null Dates.
Code: SELECT DISTINCTROW qryNoticeResponseNew.fldNoticeID, Count(qryNoticeResponseNew.[fldResponseSeen]) AS fldCount FROM qryNoticeResponseNew GROUP BY qryNoticeResponseNew.fldNoticeID;
Which is just counting the number of dates so far. It got me to thinking I need to do something like this.
Code: SELECT DISTINCTROW qryNoticeResponseNew.fldNoticeID, IIf(IsNull(qryNoticeResponseNew.[fldResponseSeen]),1,0) AS fldCount FROM qryNoticeResponseNew GROUP BY qryNoticeResponseNew.fldNoticeID;
Which pops a "cannot have aggregate function in expression" error.
I have a reasonably complex query (3 subqueries into 1 main query) which gathers data from various tables into a single dataset based on a specified date.
I now need to generate a similar dataset but across a range of dates (a month) for reporting purposes. However, I can't just adapt the query and change the parameter from a "=#<Date>#" format to a "Between #<Date1># And #<Date2>#" format
The reason being, each date has to be treated individually and has to be queried as a standalone. It's to do with the type of data I have (one-to-many relationships between tables)
So what I really need to do is run the same query multiple times, for each date in scope, then stitch all of those datasets together into one 'giant' one.
How to do that in SQL (effectively, have one query produce the dates in scope, then join that onto the other query, passing each date as the parameter - I don't even think that's possible to be honest)
The other option I can think of is to use VBA to loop through the dates in scope, then use a QueryDef object to set the parameter and read the records for each date into a Recordset object. But then I have the problem of stitching all the Recordsets together, without looping through all the fields and rows each time.
