The situation: metadata about biological specimens are collected in an Access table. The specimens come from human patients and patient data are collected in a separate table. To limit the amount of private health information we have hanging around, the patient database must be updated with new patients only when we actually receive samples from them.
So that the data entry workers know when they need to update the patient table, I want a button in the specimen data entry form that will pass an entered patient id value as criteria to a query.
The query looks like this right now:
SELECT Patients.[Patient id]
FROM Patients
WHERE (((Patients.[Patient id])=[Forms]![Specimen entry]![patient id]));
but it never has results, even when I run it from records that I know correspond to patients in the patient table. How do I fix this?
Suggestions about what to call this situation so that I can make better searches about it would also be appreciated. I'm an Access novice.
The query looks correct, but make sure the WHERE clause is comparing numbers to numbers or strings to strings (not a number to a string). Also confirm that the form and textbox names are correct. A quick test using your query worked for me.
Depending on how you plan to present the information, you can also dynamically create the query in VBA and then pass the information to the form.
For searching, I'd recommend some combination of access, dynamic, query, and vba.
alternative option
If you're only looking to see if a single patient exists in the table, it may be simpler to use the dlookup function:
If IsNull(DLookup("[Patient ID]", "Patients", "[Patient ID]='" & Me.Patient_ID & "'")) Then MsgBox "does not exist"
This will check to see if the patient exists (return a number) or does not exist (returns NULL).

Good Day,
I need some assistance please. I am rebuilding a third party Access database after it's catastrophic failure and the failure of the 3rd party developer to fix his mess. I am an avid Access Developer and know my way around an Access Database well. I am not a super VBA coder, but I can do more than my bit in VBA as well as a few other languages.
Currently, I have a database test bed with a login form that stores 3 values as public variables (gstrLevel as String, gstrUser as String, gintID as Integer). I am able to set my own "permissions" with ease in that once they login I can use the values to control the switchboard etc.
My problem now is the following. We have people recording prospective client interactions and interviews. As part of the process, every time they make contact, they record this into the database and in the process a "followup date" is created. This works like a charm. What I now need to do is warm the users if these followup dates are close or have passed so that prompt action can be taken lest we lose a prospective client.
I have a query that takes the prospective table information, and the notes table information (where the followup date is stored) and then filters the dates correctly. This in turn has been used to create a continues form to display the records that need followup soon. What I cannot seem to do is to get it to only show the logged in users followup records.
I should note that the user/agent field is a lookup field in the prospective table, and thus also creates a combo box in the Followup form. I can lock the form from changes etc, but I can't seem to get it to only display the relevant user/agent details.
I have tried:
DoCmd.ApplyFilter
Me.Filter
Me.FilterOn = True
DLookup as criteria
Using my public variables directly as query criteria
And a few other weird combinations with no success.
My problem, I believe, is the fact that the user/agent is a lookup field, and I am not sure how to filter based on that fact. If I use the gstrUser variable directly I get a type mismatch and if I use gintID directly it shows nothing.
Any ideas or advice would be greatly appreciated.
You probably have a Users table, with a numeric Primary Key (PK), while your gstrUser stores the userName.
So in the source of your Followup form, just add the Users table (joined to the Prospective table on UserId) and apply the filter on the userName field in the Users table (or whatever it's called that matches the contents of gstrUser).

1.site built by professional that left company,
2.I am inexperienced but trying/ want to learn,
3.Customer support site for service reps,
................................................
What im trying to do exactly per stackoverflows parameters.
We have a drop down box listing issues that the customer had in a column labeled "issue_type". I can export via csv entire table load onto excel then give to boss for overall review of what the issues were. However data base has a "hide" column. Its function is that when the row is updated the record is kept but the same "job or call" has only one viewable report on site (the most recently updated one). Hide is a boolean. In conclusion I want to export rows that only has the "hide" column Boolean status at 0, AND to only export the columns "customer", and "issue_type". I can seem to only do one or the other. and have researched a minimum of 4 hours to find answer myself and cannot find a syntax to do both at the same time with phpmyadmin.
I dont want an enormous data that is mostly useless but for issue type and customer but i will have to manually delete all the rows with hide = 1?
Thanks anyone 1st attempt question sorry if not correct for stackflow.
SELECT Customer,Issue_type FROM tickets where hide =0;
Elaborating on what is above for anyone that may be looking for a similar answer, SQL supports the "where" clause of which you can when properly syntaxed select many of your columns and their associated strings, booleans, and numbers to = what your looking for. Wildcards I found later for other uses work as well.
Sorry about the self answer but hopefully someone finds this usefull
I have one table called "EmployeeHours" where I have following columns:
Agent_Name Agent_Number Start_Date Time State Duration week Team
Under State column I have "After Call", "Training", "Lunch", "Tea Break" etc. Out of these "After Call and Training" are considered work hours and others are "Non work Hours". I want to add a column to this table which does this identification of work and non work hours.
I know How to do it in Excel: I have done it using the IF OR condition but I am facing difficulty in doing the same thing in MS access..
Anyone knows how to implement this IF OR Criteria in MS access and prepare that column?
Any help will be appreciated.
Something you can do that does not fully normalize your database but still gives the functionality you are looking for is to create a mapping table where you will have the different states ("After Call", "Training"...) and another field where you will have its correspondance to Work / Non work hours.
When this is done, you can create a query to calculate the Work / Non work correspondance by putting both tables in the query and linking on the Status field.
If you want you can also take this opportunity to create a table "State" with the different states in text format and with a uniquely identifying surrogate key (think Autoincrement) and replace the values in your current table with those. That way you will not sure as much text in your database (lighter) and you will be able to change the description at a single place instead of all the occurrences if you ever need to.
In a stored query, table calculated column, or form control you can use the IIF() function.
IIF([State]="After Call" OR [State]="Training", "Work hours", "Non work hours")
I have an access form with few controls on it, like start-date, end-date, move_type, mover_name etc, when user fills this field n clicks on query command button, a select query is run and it fetches records from various tables depending upon the criteria mentioned by the user.
Later the same records are exported to excel file and a report is generated for user.
Now I need to do more with this, my select query has a field "quoted-price", depending upon the price quoted the records need to be sorted out.
EX : if quoted_price < 500 then it is a "domestic apartment1", if quoted-price is >500 And <1500 it is "domestic Apartment1" etc.
Now I need to do more with this, my select query has a field "quoted-price", depending upon the price quoted the records need to be sorted out.
EX : if quoted_price < 500 then it is a "domestic apartment1", if quoted-price is >500 And <1500 it is "domestic Apartment1" etc. and when all the records generated through select query are searched on this criteria, the records need to be grouped accordingly. Later the count for individual category is multiplied by a unit value and total charge is calculated.
I tried building many queries to do this and tables to refer to value but of no use. Any help will be much appreciated.
are you looking to create a new field depending on the condition? That may be step one of what you are trying to do, If so that is pretty easy. See here: http://allenbrowne.com/casu-14.html
I'm not a programmer, but trying to learn. I'm a nurse, and need to pull data for medical referral tracking from a database. I have a piece of GUI software which builds JOIN queries for me to pull things from the database. One of the operators I can use in the drop-down is "IN." The referral documentation is stored in the table as codes made up of one to three letters. For example, the code for a completed dental referral is CDF, and the code for a dental referral is D.
I want to build a report to allow other nurses to pull all their outstanding referrals, so I'll want to pull "D" but not "CDF"
If I use IN as the operator, and set my parameters to 'S','D','BP' {etc} will that also pull the records which have the other, longer codes which contain those same letters? (like CDF, CSR, CBP)
I don't want to test it because I only have access to the production database, and I don't want to hose up actual patient records. Thanks in advance for any help!
Assuming that the column that holds the referral code holds one and only one code per record (which is what it sounds like) the query should function as you want and will not attempt to match substrings.
In any event, there's no danger that a query in the form IN ('S', 'D', 'BP') will match substrings. To perform substring matches in SQL you have to use the LIKE operator.
The situation in which this will not work is if the referral code column holds multiple codes separated by commas. This is an all-too-common mistake in designing databases but if the product you're using is commercial rather than home-grown, I think it's very unlikely to be the case. If it is, searching it is much more difficult.
