Microsoft Access keeps an internal count of the total number of fields in a database table and has a limit of 255 fields per table. Each time that you change a property for a field,

the column count is incremented by 1. Also, whenever you delete a field, the column count isn't decreased, but remains the same. When you delete a field, Microsoft Access does NOT reset this counter. So it's possible for you to have less than 255 fields and still get this error message. If your field count is less than 255, just compact the database again which should reset the internal field count counter. This error is more commonly encountered in a database that hasn't been correctly normalised and has excessively large tables with many, many fields. In this case, the better solution would be to redesign the database so that it is normalised to third normal form.

Is there a way for me to do this using http://stackoverflow.com/questions/15189013/microsoft-access-queries-too-many-fields Microsoft access (I can use 2007 or 2010 versions)?

If the "complete dataset" you want to produce will have more than 255 columns then you won't be able to do that in a single Access query. One possibility might be to create several queries with no more than 255 columns each, export them to Excel, then paste them together side-by-side into a very wide Excel document. Excel_2010 worksheets can have up to 16,384 columns. It could be a bit tedious to do manually but there would be some opportunity to automate the process, at least in part. You'd also have to be careful t

Is there a workaround for "too many fields defined" P: n/a M G Henry I have a https://bytes.com/topic/access/answers/574131-there-workaround-too-many-fields-defined tabbed form that contains 12 different "pages" and when I try and run the form I get the error message too many fields defined --- which I believe is the 255 field limit in the record source. I was wondering, that if https://www.experts-exchange.com/questions/21160216/Union-of-3-Access-Tables-Error-Too-Many-Fields-Defined.html I were to break the pages down to include subforms... is the number of fields contained in the subforms added to the field limit for the main form ??? Is there some other way to work around this error message ??? too many I am putting the pages of forms on a tabbed control to keep the form syncronized during the add and edit phases. Dec 6 '06 #1 Post Reply Share this Question 12 Replies P: n/a Allen Browne You can have up to 255 fields in a table or query, and up to 700-odd controls on a form. A subform counts as one control on the main form, and can have its own controls and RecordSource (so fields.) However, a well designed table rarely too many fields has more than 50 fields. If you have hundreds, there's a very high chance that you are designing something that looks like a spreadsheet, i.e. it is not relational. One dead giveaway is if you have any repeating fields - sequences such as: Week1, Week2, ... Employee1, Employee2, ... Monday, Tuesday, ... FirstQuarter, SecondQuarter, ... Item1, Item2, ... Whenever you see this kind of thing, it always means you need to create a related table with lots of records instead of having lots of fields in your table.

Want to Advertise Here? Solved Union of 3 Access Tables - Error: "Too Many Fields Defined."? Posted on 2004-10-07 MS Access 1 Verified Solution 42 Comments 2,435 Views Last Modified: 2012-05-05 I have 3 Access tables with 182 fields and 150,000 records each. All 3 tables share the same 182 fields. When I try to Union them, I get an error: "Too Many Fields Defined". I'm confused because they are the same 182 fields, why "Too Many Fields Defined"? I didn't define any new fields! It seems like there is a memory issue but isn't the error msg misleading or am I missing something? My goal is to get the average of all 450,000 records by 18 predefined catergories. Am I out of luck? 0 Question by:rx9 Facebook Twitter LinkedIn Google LVL 11 Best Solution byJokra_the_Barbarian I just tested my theory, and I am correct. I created 3 tables with 86 columns each and attempted a union query which failed.

Dump your query SQL here. Also, just out of curiosity, why are you trying to UNION three tables with that many records? Perhaps there is a workaround available that will meet your needs. Hope this helps. -Jim 0 LVL 12 Overall: Level 12 MS Access 9 Message Expert Comment by:pique_tech2004-10-07 In Access, there are two ways to do a UNION query: TABLE tablename1 UNION TABLE tablename2 UNION TABLE tablename3 ... OR SELECT * FROM tablename1 UNION SELECT * FROM tablename2 UNION SELECT * FROM tablename3 .. So as long as you're doing it one of those two ways, I don't get it either. I could understand
