Access 2016
I feel like a high schooler who has forgotten how a period works in a sentence.
I have a blank database. I create 1 table named TestTable. One column called Amplitude with one record 14.
It says "Microsoft Access cannot find the name TestTable you entered" Error 2482. I've googled and searched on here, as far as I can tell I am using the correct syntax. Granted this is the first time I've used If statements directly in the macro form (I usually convert to a module) so maybe I just don't know some quirk about the If statement field, but I've looked at tutorials for macros and If then blocks and I've seen sample code with people using the same syntax. Where am I going wrong?
Per June7
Cannot reference table or query directly, even if there is only one record. Use DLookup() or DCount().

I am having some trouble creating a database in Microsoft Access. I have a series of criteria in the same row of a query, many of which look like the following
>=[Forms]![Form1]![Tensile_min] And <=[Forms]![Form1]![Tensile_max] Or Is Null
If I close then reopen the database, Microsoft Access reformats the query to a logically equivalent set of permutations using multiple rows.
The criteria go from this to looking like this, which creates a set of criteria so large it crashes the database. Is there a logical equivalent of the code included above that I can write, which will not reformat?
Thank you for your help.
You could start with:
Is Null Or Between [Forms]![Form1]![Tensile_min] And [Forms]![Form1]![Tensile_max]
If no success, then
Between Nz([Forms]![Form1]![Tensile_min], [YourFieldName]) And Nz([Forms]![Form1]![Tensile_max], [YourFieldName])
Further, do specify both [Forms]![Form1]![Tensile_min] and [Forms]![Form1]![Tensile_max] as parameters to free Access from guessing the data type of these.
I am working on a small application in Access Services on SharePoint to log colleagues leave requests, and I need to work out a data macro to calculate how many days of leave they have remaining from their allowance.
I have a table [Colleagues] with all of the user data, for simplicity I'll reduce it to [Email] and [Allowance] in days. I have another table which stores the requests [Requests] including the number of days to deduct in each approved leave request [Days Requested].
I have set up a query that returns all approved requests for the colleague and I would like to use a data macro that is triggered to run when the colleague logs in. As you cannot use aggregate functions in Web Applications, I am currently using ForEachRecord in the query to total the number of deductible days, however I cannot work out how to return that to a field in the [Colleague] record.
According to the Access help, I should be able to set the value to a LocalVar and use it in expressions as simply as referencing [Deductible Days], however this is not working.
Any help?
I finally worked this out after much tinkering.
In my query I included the [Colleague Email] field as well as the [Days Requested] field, and then when my Application loads it navigates to a form created from the [Colleagues] table. I have modified the Data Source of the form to link the [Email] field in the query results to the [Email] field in the [Colleagues] form.
Following this I was able to create an unbound textbox with the data source =Sum([Days Requested]) referring to the relevant field in the query. Voila! I now have the value to play around with in my application.
Hope that helps, took a lot of fiddling around. No data macros needed after all, but its a method I shall remember in future, opens up a lot of possibilities.
If I understand your situation correctly, I was faced with a very similar problem.
I believe the solution used here will work for you. It involves using a query to Sum up the values (we would use Sum where he used Count), use a Data Macro to run the query and then have have an On Insert/On Update trigger the Data Macro:

Let me know if this works for you. It worked for me!
I have an Access 2007 report which has a table as a data source. I have a few columns of data that directly pull data from the table in a summarized way (using report groups) and the last column is the total of the first 6 columns. Simple enough.
Now the expression that calculates the sum of those 6 columns sometimes returns #NAME? and sometimes does not. I have more than triple-checked for any error, typo, whatever.
There is no space in front of my expression;
The expression does start with an =;
The references to columns in the table are all valid;
No control has a name even remotely similar to any column in the source table;
I have tried generating the expression using the expression builder;
There is no conditional formatting tied to any control;
There is no VBA code used at all in generating the report.
Also, sometimes if I copy the one of the boxes with #NAME?, delete it and paste it back then all the #NAME? errors disappear. Then I save and reopen the report and the errors are back.
I'm out of ideas for this. I can't post screenshots or distribute the file due to its nature.
Thanks !
I had similar problems...The solution was that I have used unicode characters in Names. For example a Text Box with the control source "dataščž" had the Name "datačšž". This was working in previous versions of Access, but not anymore. Changing the Name "datacsz" solved the problem.
I am reworking and expanding a somewhat complex database schema that has a small number of tables and queries but they are closely related. The only problem I had with it was that in one of the tables the 2 fields that were relating to another table were using the field name of the record and not the ID of the record.
I changed the referring fields data type from text to number and entered some data. The queries and the reports work fine with 1 exception:
There is one report that uses both referring fields. One of the fields is ok but the other one shows symbols instead of numbers. ( The IDs in my sample entries were 14 and 20 and the symbols shown were a double barred music note /alt code 14/ and the symbol for an end of a paragraph /alt code 20/ ) Investigating further I have found that if I make a query that contains the query source for the report both fields display fine, but if I add another table to that query the second field once again shows symbols instead of numbers.
I have found a workaround of this by converting those fields back to text and the id fields in the other tables to text as well. This text key will probably haunt me later on, so I'd like to make it right before it is too late.
This is all access 2010 btw. The source file was already in 2010 (couldn't open in 2007 even)
Sounds like a corruption issue for sure. I would try adding a new column and run an update query to populate it with the values from the old column (maybe use cint(indexfield)), then delete the old column.
It might also be a good idea to decompile the database. This often helps resolve corruption issues.
I'm using MS Access 2007 as a front end and have all linked tables in SQLServer 2008 R2 backend.
In a form in Access I am trying to execute the FIND button either in the ribbon or by creating a button on the form with the expressed purpose of looking for records with a specific value in a particular field.
When I complete the entry in the FIND window, I click on Find Next. In some cases, the record(s) is found immediately. In others, it can go for hours only to report that it can't find anything (when I know it should).
The table I am looking in has approximately 99,000 records in it. It doesn't seem to matter whether or not the field is indexed.
Is there something I'm doing wrong, or is Access unable to handle this? Also, is creating a stored procedure with handling multiple search requests and passing the info to Access the answer?
The find methods are known to be slow with ODBC data sources. Here is what the Access 2007 Recordset.FindFirst Method help topic says:
When working with Microsoft Access database engine-connected ODBC databases and large dynaset-type Recordset objects, you might discover that using the Find methods or using the Sort or Filter property is slow. To improve performance, use SQL queries with customized ORDER BY or WHERE clauses, parameter queries, or QueryDef objects that retrieve specific indexed records.
Futhermore, binding an Access form to a record source of 99K records is a performance challenge. Use a query as the form's record source, and design the query to return only one or a few rows.
Give the user an option to choose a different set of rows, and modify the form's record source property to reflect the user's choice.
This depends on the type of search you need and on the data type of the column (field) to be searched. For example, if I have a text data type in an indexed column and I search using Start of field or Whole field, it will be quite fast, however, if I search for Any part of field, it may well fall over. In other words, if Access can use an index for the search, it will work, even on quite a large table, otherwise, you may be best with a stored procedure, though I doubt that will be fast without an index, either.
