Tables :: Counting Occurrences In 2nd Table
Aug 11, 2013
I am having difficulty in solving a problem in Access 2010 which was a doddle in the Excel version of my database.
Table1 (MailList) has a field 'Member Name' and a new field 'NumberGroups'.
Table 3 (GroupMembers) is a junction table and also has a field 'Member Name'. Records for 'Member Name' are repeated in several 'Groups' within Table 3.
I require to Count the occurrences of 'Member Name; in Table 3 and display them in Table1 'Numbergroups'.
I have written numerous Queries to try to achieve this, but without success. Does it have to be a Query, or can it be achieved entirely within the structure of Table1?
In addition, I need to interrogate the resulting numbers in Table1 'NumberGroup' to determine how many member attends 7,6, 5 etc different Groups. Again this was extremely simple in Excel but I can't crack it in Access.

I have a Table A that is a list of ID's. In table B, each ID (from A) could appear multiple times, or not at all.
How do I get a count of how many times each ID in Table A appears in Table B? ie. 0 or 1 or 5 or whatever.

I have a table which is basically a calendar containing the columns (i) date, (ii) special info relating to that date (iii) morning volunteers and (iv) afternoon volunteers.
In the "Morning Volunteers" there are up to two names with sometimes a first name, sometimes an initial but always a family name.
The same is true for the "Afternoon Volunteers".
What I want to do is, using the Family name, to find out how many mornings/afternoons each of the volunteers has manned the Visitor Centre.
As I am new to Access I have no idea whether this is possible and, if so, how to do it.
I can do it by exporting the table to Excel but this is very clumsy and time consuming
I am using Vista and Access 2003.

I run a Query to determine how many employees attended a meeting, showing the number of years they have worked at the company.
(Example output of query)
Employee Name Years with Company
John Doe 3
Jane Smith 1
Bill Doe 3
Rick Mills 1
How do I count the number of people with each range or particular number of years with company? For example:
2 employees have 1 year with company
2 employees have 3 years with company

I have a table that tracks different events and the actual date they occurred. I am trying to write a query that counts the number of each event that occured by month. One issue I am having is if an event had no occurrence during a month I want to return 0 raher than no data for that event.

I have subform (datasheet) with a column for gender indicating "Male" or "Female" I wish to place the totals for each gender (and total overall) on the main form footer. I have tried objects of every type with calculated controls using conditional count formulas such as
=Count(IIf([Gender]="Male",0))
But I get #error on everything.

I need to add a column to a crosstab query that counts all of the occurrences of "P" in a particular row in the crosstab query. Basically "P" stands for "Present" and I need to know how many days each employee was present for his/her shift. The SQL for the crosstab query is as follows:
PARAMETERS [Forms]![frmDashboardReports]![txtStartDateAndTime] DateTime, [Forms]![frmDashboardReports]![txtEndDateAndTime] DateTime;
TRANSFORM First(tblAttendance.AttendanceCode) AS FirstOfAttendanceCode
SELECT tblAttendance.EmployeeName
FROM tblAttendance
WHERE (((tblAttendance.AttendanceDate)>=[Forms]![frmDashboardReports]![txtStartDateAndTime] And (tblAttendance.AttendanceDate)<=[Forms]![frmDashboardReports]![txtEndDateAndTime]))
GROUP BY tblAttendance.EmployeeName
PIVOT Format([AttendanceDate],"Short Date");
This returns an "AttendanceCode" against each employee against each day in the specified time period. I just need to be able to "sum" those codes in a column.

I was wondering whether it is possible (and if it is, the way) to perform the following task in Microsoft Access: there are two tables; first one consists of three columns
1) ID
2) tweet text and
3) date.
Second table is a single vector of words, like a lexicon. For every row of the first table, I want to measure occurrences of the words of the second table (lexicon) in the tweet text column (2). Following, I want to add a new column in the first table, in which I will keep a record of these occurrences. This is what I have done so far:
SELECT *
FROM Tweet_data
WHERE Tweet_text LIKE "*" & Positive_sentiment & "*";
However, I most probably have to make some changes in the part following the LIKE

I am trying to count the number of times a client has engaged with our company. I have a company table, a reservation table, a rapid prototyping table and a project table. There is a one to many from the company table to each of the other 3 tables as can be seen in the attached picture.
Is there an easy way, in a single query, to list unique company names that exist in 1 or all of the 3 tables?

Hi,
I am trying to get a count for the # of records in 5 queries by creating the count in one query, but the only way I can do that is if I create 5 additional queries for each count. Is there any way to use multiple count statements in SQL.
Example:
Query Q_Duplicates:
SELECT COUNT(*) AS CNTDup
FROM Q_Duplicates;
Query Table T_FTOR:
SELECT COUNT(*) AS CNTFTOR
FROM T_FTOR;
....& there's an additional 4 other query's that do the same Count...There must be a way to create one query that counts the # of records for each table!
PLeaseeeee Help...

I am pritty new to access and have been tasked with creating a database !
I have two tables one called main which has 26,000 claims (listed under there part number).
The other table called part numbers is a list of all the part numbers in the main table but with no duplicates (126 part numbers)
I need to somehow count how many times a part number apears in the main table. Maybe display a count in the part number table as a extra field ? then i could put this field into the form i created to browse the parts numbers (to show how many times the part number appears in the main table)

Hi
I am currently creating a report form which only calculates
fields/columns in my main table. However I am currently struggling
counting text fields and checked fields as well as data fields in this
table.
I want it to count all the "yes" checked fields in my main table targeting
another column's data e.g I've got column with Category listed as 1, 2, 3, 4 and 5.
Along with this there is a check box to say that a job was completed under cat. 1,
2, 3, 4 or 5.
I have managed to get the formula to cound all checked boxes in the databases,
but what about targeting only say category 1's checked boxes or category 2's checked
boxes. I need to work out %'s from these individual totals as well.
Any suggestions on this would be great!

I have been trying to create a report to count equipment tested between two dates:
I am using Access 2000 (old I know) and I have 21 different tables with the fields laid out the same. For the moment, I will list five of the tables: Servers, Laptops, Printers, Workstations, and Monitors. The criteria I draw from each table are the fields Model#, Part#, Serial#, Test Date, Retest Date, and Technician.
I can create a report from a query (say laptops). The criteria I is BETWEEN[Enter Start Date]AND[Enter End Date] under the TEST DATE field. Works great! In my report I use =Count(*)&" "&"Unit(s) tested" & "Between "&[Enter Start Date] & " and" & [Enter End Date].
That works great too.
I am trying to create ONE REPORT using ONE Date range and display how many units were tested:
Example:
Units Tested between March 1, 2014 and March 31, 2014
Servers 9
Laptops 23
Workstations 15
Printers 18
Monitors 31
If I can get these five tables, hopefully I can add additional tables to the same report as I need them. I am not savy with VB code, but will give it a go with some direction as to where to put it and how to add to it.

Thought I'd be able to find out easily, but.. here I am...
How can I query the number of occurrences of a string in a field, e.g.:
if a name field has the text: Martin Lacoste
how can I get it to tell me there are two "a"s in the field?
I can use InStr to find one, and make a few more queries to find a few subsequent, but the data I need to search could have 30-40 occurrences of the desired text in a field.
Ideas?
Thanks!

I'm trying to create ONE query which would fetch me the number of occurences on a particular value in a field while keeping duplicates.
For instance let's say i've got the following table
Color......Value
Red.........5
Red.........8
Orange....1
Then i would like to have the following result from my query
Color.........Value.......CountOfColor
Red............5..............2
Red............8..............2
Orange.......1..............1
I know i could achieve this by creating a view first. For instance by saving this expression as qryCountOfColors
Code:
SELECT tblColors.Color, Count(tblColors.Color) AS CountOfColor
FROM tblColors
GROUP BY tblColors.Color;
And then make the following query
Code:
SELECT tblColors.Color, tblColors.Value, qryCountOfColors.CountOfColor
FROM tblColors INNER JOIN qryCountOfColors ON tblColors.Color = qryCountOfColors.Color
However I'm woundering wheter or not I could achieve it without creating the qryCountOfColors.I'm myself into a mental meltdown . I've been playing with the idea of creating of creating a subquery to achieve this but im unable to get to work
Code:
SELECT tblColors.Color As BANANA, tblColors.Value, (SELECT Count(tblColors.Color) AS CountOfColor FROM tblColors GROUP BY tblColors.Color HAVING (((tblColors.Color)=BANANA))) AS Expr1
FROM tblColors;

I've always used an audit trail for tracking changes of records that already exist but I have had a situation come up where I now need to track records that have been deleted. For example, if I delete a record in the datasheet view.
I've seen several examples how to do this, with the most common seeming to store the data into a temporary table while waiting for the delete confirmation. If I am reading the notes correctly, it's done this way to capture occurrences when multiple records are selected to be deleted. Is this the best approach for this type of task?

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.
