Blank Fields in NOT Null Query Criteria
Thank you for taking the time to report an issue.
What's wrong... Please write below.
Any records with null or blank in any of the fields on the form for which the user does not enter search criteria will not be included in the results.
If I use this in my query:
Like [Forms]![Search Clients]![LicenceNo] Or Is Null Or ""
I get all the null and blank results regardless of what the user enters. But what I want is to get all the results only if the user does not enter criteria.
Field: [FieldName]=[Forms]![FormName]![ControlName] or [Forms]![FormName]![ControlName] Is Null
Which works as expected, allowing me to leave it blank and it will pull records. when I leave this blank it pulls all records regardless of MaritalStatus:
[MaritalStatus]=[Forms]![Main Form]![cboMaritalStatus] Or [Forms]![Main Form]![cboMaritalStatus] Is Null
How would I modify that query or the form to allow me to pull ONLY rows where the MaritalStatus IS NULL?
I want to write an sql code for the query that sets the criteria to the value of the text box in the search menu if the text box is not null, and leaves the criteria field blank if the text box is null.
Here is an example of what I have tried in one criteria box:
((Table_Closure.[Job Number]) = IIF((Forms!Search_Menu![Job#_TXT]) = Not Null, (Forms!Search_Menu![Job#_TXT])))
But the search still isn't working of a text box is left blank.
background of what I'm trying to accomplish: I have set-up a column in a query to count the amount of null values for each record. However, when a field has information and then is deleted, that field is now read as blank (or 0 value) instead of null and my count is thrown off. I used an update query to change those blank fields into nulls.
Ok this being said, I do not want to have to keep changing each field each time I find blanks, so my question is, is there a function or macro or module that will automatically change a newly created blank field into a "null value"?
I want to design a query or report to retrieve dates from Field A. The criteria is:
Field A must be filled (I.e. there is a date, not a blank); and when dates in any field of B or C or D are not blank, A must be more recent than this/those date(s).
How do I write it? I made "A is not null" in the first criteria. And then I think I should write something like when B or C or D are not blank, A B or C or D.
I would use expression builder. I tried a couple of them I was not able to make any of them work.
Between, I am using Access 2010. The expression builder has symbols like "&" and
"AND", what's the difference?
I whave been trying to do this without creating a union query. But this is what I have so far but it keeps saying I have a syntax error and sometime I have gotten you are missing an operator.
I know what those errors mean but I am getting a little stuck at the moment.
I am using a form to pass the search parameters to a query. The criteria line in the code has a statement like the following:
This allows the user to enter a wildcard search for partial entries which is very helpful.
This all works properly.EXCEPT when any of the search fields have no data in the database. For instance, if one of the 10 fields is missing data in the database (that field is null), then that record is overlooked for some reason.
Passing these combo boxes Values to the Query selection fields is easy; but I don't know how to handle the situation where the user did not select specific value in one filed or more.
I know I can use 'Is Null' in the query criteria in a specific column for the field - but then I have to make a very complex criteria, resulting in 5 * 5 situations (first field is null,2-5 are not, second filed is null the others are not etc, etc.)
