Queries :: Count How Many Fields Are Missing For Each Record
Jun 27, 2013
I have a fairly simple query to weed out all the records in our database that are missing vital pieces of infomation :
Code:
SELECT Contacts.Name, Contacts.Address1, Contacts.Address2, Contacts.Town, Contacts.County, Contacts.Country, Contacts.PostCode, Contacts.Telephone, Contacts.Code
FROM Contacts
WHERE (((Contacts.Address1) Is Null) OR ((Contacts.Address2) Is Null) OR ((Contacts.Town) Is Null) OR ((Contacts.County) Is Null));
Is there anyway to count how many fields are missing for each record ?
I have three tables: Employees, Gender, Diversity. Both the Gender and Diversity tables are one to many relationships with the Employees Table. I am trying to run a query that will output a count of all diversities and genders. For example:
I am trying to get all counts, even if the combination of diversity/gender is not in the employees table. I am going to use that information in a Crosstab query.
What I thought would work was do a Left Join For Diversity and Employee such as:
SELECT Diversity.[Diversity Description], Count(Employee.ID) AS CountOfID FROM Diversity LEFT JOIN Employee ON Diversity.ID = Employee.Diversity GROUP BY Diversity.[Diversity Description];
Then, do a Left Join for Gender and Employee such as:
SELECT Gender.[Gender Description], Count(Employee.ID) AS CountOfID FROM Gender LEFT JOIN Employee ON Gender.[Gender ID] = Employee.Gender GROUP BY Gender.[Gender Description];
And then do a Union. But that doesn't work.
Any thoughts or comments would be much appreciated!
I'm trying to create a single, Update Query in Access 2007 that does all of these 3 things:
Update (skipping zero-length values) Append Automatically handle missing Fields without showing any "Enter Parameter Value" prompts.
I've managed to accomplish the 1st & 2nd items on my own, but I'm stumped on the 3rd. In essence, what I'm looking for is a way of telling Access to automatically use a zero-length/null value for any missing Field(s) the Query encounters, so long as it does not involve manually modifying the Table beforehand. Automation is key. And that's where you guys come in.
Attached, is a diagram of the desired results applied to a set of sample Tables. And here's the SQL code for the Update Query adjusted to work with those sample Tables:
Code: UPDATE Table_1 RIGHT JOIN Table_2 ON Table_1.ID = Table_2.ID SET Table_1.ID = NZ([Table_2].[ID],[Table_1].[ID]), Table_1.Company = NZ([Table_2].[Company],[Table_1].[Company]), Table_1.Address = NZ([Table_2].[Address],[Table_1].[Address]), Table_1.Phone = NZ([Table_2].[Phone],[Table_1].[Phone]);
The journal ID above was an accounting entry, debit $16,797 and credit $-16,797. because it was entered as a reversing journal in the system, the table has captured the Journal ID with 2 dates. For my purpose i only want the one date (MIN) date, the total amount of the journal (either the debit or credit amount 16,797) and the total number of lines the journal ID has so in this instance I want the count to be 2 and not 4.
Im thinking with the total sum because theres debits and credits is there a way to do the absolute value of the journal MONY_A then divide by 2?
current SQL SELECT [One Year Data Lines].JRNL_I, [One Year Data Lines].CNCY_C, Count([One Year Data Lines].JRNL_I) AS CountOfJRNL_I, Min([One Year Data Lines].JRNL_D) AS MinOfJRNL_D, [One Year Data Lines].BUSN_UNIT_I, Sum([One Year Data Lines].MONY_A) AS SumOfMONY_A FROM [One Year Data Lines] GROUP BY [One Year Data Lines].JRNL_I, [One Year Data Lines].CNCY_C, [One Year Data Lines].BUSN_UNIT_I HAVING ((([One Year Data Lines].JRNL_I)="0002888269") AND (([One Year Data Lines].CNCY_C)="aud"));
I tend to work with large amounts of data (extracts from company systems) and I create a lot of Access/VBA based tools to automate processes.
I have an annoying error which has always appeared but I don't understand the root cause of it.
When viewing a query, if I filter, I get an error message pop up (though after clicking through the error I can still use the filter function):
"syntax error missing operator in expression 'name of field'".
This seems to happen when I add several calculated fields. Here are some examples of the conditions and calculated field formulas I'm using in this current one:
Conditions: <>"CINEMATIC" And <>"SFX" Not Like "*_ZZ*" And Not Like "*test*" And Not Like "EP_*" [Forms]![FRMscriptPrintReview]![selectLangCombo]
I get the impression that its more of a bug with Access as the formulas aren't complicated really but need confirmation on this and if there is a way I can avoid it.
I'm building a health data system that stores data from health tests as follows: [test01], [test02], [test03],.........[test25], etc etc. Each of these tests comprised of a "Pass"/"Fail" value.
Now, i'm building my queries for a feedback report to hand over to the client that is based solely on the 1 single client record. In other words the queries are designed to return only 1 single data record to be placed in the client report where the based on the corresponding [TestID].
So within this 1 data record i want a query to count the number of times "Pass" appears in the test fields?
As there are some 40-50 [test##] fields in this one test battery i don'y particularly want to go back and code an IIf statement for each component if i can help it.
I’ve attached a zipped example of the problem I am having with customised navigation buttons.
In my main database the form “subfrmPersonsContact” works perfectly. I have exported it to a new database and now the customised record count fields do not work at all – they are in fact blank even though the navigation buttons do still work.
The code running the form and the record count fields is listed below – I have no idea why it’s not working.
Any help would be greatly appreciated.
Cheers,
Rusty :D

Now, I want to know how many 1s are there in Rec3 the answer is obviously 2 but I want a field(F4, for e.g) that calculates F1+F2+F3 showing all their 1s 2s and 3s.
A solution I found was...... F4=IIf([F1],1,0)+IIf([F2],1,0)+IIf([F3],1,0)
But I have over 50 Fields that contain 1s and 2s and I can't count them all by using this formula as it will be tremendously long and access will reject it.
So I need another formula(or function) that will look up for the 1s across multiple fields and show the total count for each record in a new field.
Tried 'look up' function but achieved nothing ....
I am trying to create a clean database and code to generate a report.
I am trying to count the number of null fields in one of my queries:
However, because of this expression, I cannot carry other fields with it. So the end result looks like:
But I would really like it to spit out the following information:
Total Not Fixed: 241 Department: Sustaining Eng
is there a way to create an SQL query to simply add data: I have tried the following:
Code:
ALTER TABLE qrySustainingEngNotFixed2 ADD Dept TEXT(25) Insert Into qrySustainingEngNotFixed2 (Dept) Values (Sustaining Eng) SELECT TotalNotFixed, Dept FROM qrySustainingEngNotFixed2;
The above isn't working. Keep in mind that I want this is just for display purposes. I pondered making a custom table and then making a Union Query, but I'm trying to do this all in one SQL statement.
This is kind of a weird problem, and everything I've learned about access has been on my own through empirical experimentation so forgive my if my description doesn't make sense, or if I overlooked something really simple. (Apologies for that, I've looked over all the guides on queries and record counting I could find and got nothing on this.
I can't figure out a better way of explaining my situation so I'll do the best I can.
I need to make a query that shows the number of people that have registered for a class. In one table I have the primary key Schedule ID which is the unique class, which is linked in one-one relationship with another field of the same name. In the second table with that field I have the field schedule ID which shows up multiple times, for each student enrolled in the course, second is the field Participant. There is the following data: Schedule ID...Participant 1 ................ <name1> 1 ................ <name2> 1 ................ <name3> 4 ................ <name4> 4 ................ <name5>
What the result of the query should look like is this:
Schedule ID...Number of participants 1 ................ 3 4 ................ 2
But instead I get Schedule ID...Number of participants 1 ................ 5 1 ................ 5 1 ................ 5 4 ................ 5 4 ................ 5
I have tried various variations of the Count and Dcount functions but I always wind up with that result (if it works at all)
This is the expression I am using:
Expr1: DCount("[Schedule ID]","Class Roster")
where "Class Roster" is the name of the Table that Schedule ID is located. I have tried changing it out with the name of the first table, and I have tried using participant instead of Schedule ID, but neither works. So far I've been able to use a crosstab query to get something roughly what I want but I think the assignment calls for a regular query.
Again, sorry if this doesn't make any sense, I did my best to explain it, and I couldn't find an answer anywhere. Thanks in advance for any help!
Oh, by the way, it's access '03 that I am using.
UPDATE: I have a second problem I'm trying to solve, and this one seems more confusing than the first to me. I have a table with the following fields:
Project Name, Task name, employee ID, Production Week, and Hours Worked. The first two being text and the last 3 being numerical.
I need to create a query that totals up the hours worked for each employee (one employee ID can show up under multiple projects/tasks) and returns the total hours in a particular week (week 20) of each employee that has worked over 40 hours, and only the ones that have worked over 40 hours. I can not figure out how to create a field that will sum up the hours worked for a given employee, nor can I figure out how to show only rows where the total hours record exceeds a certain amount. It seems like I would want a conditional like an IIF statement but those seem to be only for returning values, not showing/hiding.
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 am basically looking for a way to display the total number of records for a selected number of tables and queries in my database on one screen or on one single page view. The problem with using reports or forms is that they tend to bind you to a single table as a record source. This summary would require multiple tables and queries. The summary data would look something like this with a total coming from a Count() or count type function:
# of records: 3000 # of records to insert: 500 # of records to delete: 400 # of records to update: 2100 # of records changing location: 100
am trying to change the tab order but have noticed that some of the fields are missing from the tab order form. I am attaching a screenshot to show which tabs are missing.
I have a query that creates counts of fields based on the data in other fields, basically it tells me that in a table there are two entries with value ABC????? and three of DEF????? , the query works perfectly.
When I create a form to display this data and base the form on the Query I keep getting a message box asking for the ID (key field) from the base table.
If I type * in the box (to denote all values) and press enter I get the results expected.
I have a weird situation and I was wondering if anyone has had an issue with this. I have a record missing from a table. Normal Users are not allowed to delete records from the Form view. There is a blank record where the record should be. The auto number counts from 37, 38, 40. Record 39 is missing and there are blanks where it should be. The autonumber field is my Primary Key and it is blank just like the rest of the fields in the record. I know that the record existed at one time because one of the DB users has a report referencing that record. Any Ideas?
I have a table with multiple fields and each record in the table may not have data for all fields. I need to write a query that will pull only the fields that are populated for each record from the table.
Using a single-step Access query, I need to retrieve, for each PatientID, the most recent LabDate and Result *of a given LabID*. Thus, from the example dataset above, the desired output for LabID 55 is:
I have searched this forum and others, but have not found an answer that I can directly tanslate to my situation. I have successfully written queries (with included subqueries) that retrieve the most recent of all the Labs, but have failed at obtaining a result dataset that contains only the records within a specified LabID.
For example, the query below fails because whenever the most recent of *all* the LabDates is not the same as the most recent of *the LabDates with a LabID=55*, the correct record is not included in the results. In the example dataset above, 0 records are returned.
SELECT a.PatientID, a.LabID, a.LabDate, a.Result FROM Labs AS a INNER JOIN (SELECT PatientID, MAX(LabDate) AS MaxLabDate FROM Labs GROUP BY PatientID) AS b ON (a.PatientID = b.PatientID) AND (a.LabDate = b.MaxLabDate) WHERE (((a.LabID)=55));
I have an application where I have to read a big VCF file in VBA, extract the information and place it into records of a table. Of course I can read as a text file, but the structure is quite cumbersome to implement with many fields missing in different records and it is not a one time job.
I have created a multivalue field which allows me to select many names which form s a circulation list for a report. The multivalue drop down works ox in table view, however when I am in form view the dro down is missing the check boxes....
I made a query that calculates the sum of from a table that contains defect types and numbers.
The problem is when after the inspection there's no defect no values will be entered in the mentioned table. And running the query the result is 'NOTHING'.
I tried to deal with this 'nothing' putting this in another query:
I want to set up that if there is missing value of the fields, then we cannot go to next record or exit the form when we click to do next action.
I tried to add the code in the After update event, or Exit event,
Example Code: if (isnull([Zip]) or len([zip]) = 0) then msgbox "missing" [zip].setforce end if
when I click to go to next record, or exit the form, it give out message "missing", it work fines, but, it still go to next record, or exit the form after the message.
My table occasionally gets a second record added for the same person. What is the easiest way to update the new record with the non-zero fields from the older record, then delete the older record? There is a unique id field as well as a timestamp, so knowing which is older isn't a problem. Is there an easy way to do this?
I have a query that will draw down student details who have completed a course in a given month (May for example), i would like to use this data to identify those learners who are not enrolled on a course in the next Month (June for example). There is no field that denotes whether a student has left only that a course assosciated with their ID has a completion date within that Month. There are approx 250 records.
In my head it should work something like this
1) Identify all learners who finsihed a course in May (Identify learner ID, must have a course end date in that month)
2)Cross reference these against all those who started a course in June and identify the students that have completed in May but did not start a course in June.
Is it possible to store all those who completed (May) in a table/query and cross reference those who started in June and identify of the May completions who did not start in June?
