Tables: "Too many fields defined" error message Author(s) access too many fields defined union query Dev Ashish (Q) When I try to save a table, I keep getting the error too many fields defined access 2010 query message "Too many fields defined". What's causing this to come up? (A) Access keeps an internal count of total number of fields in a table and has a limit

of 255 fields per table. Each time you modify a field or add a field, this count increases by 1. When you delete a field, 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. © 1998-2010, Dev Ashish & Arvin Meyer, All rights reserved.

quick word of caution regarding the Error code 3190 that may occur when using the DoCmd.TransferSpreadsheet Method to export data. I previously had been using a procedure to export my data without any problems, then I went ms access too many fields defined query to use it again and kept getting this error. I mean I only had 12 too many fields defined access export excel columns in my query, so what the …?! After doing some testing I ended up determining that it had nothing to do with

the field count, but rather with the fact that the file already existed. Basically, the DoCmd.TransferSpreadsheet Method was unable to overwrite the existing file and raised this most useless error! So beware that Error 3190 - Too many http://access.mvps.org/access/tables/tbl0002.htm fields can also mean cannot overwrite the existing export file. The fix is extremely easy, simply check for the file and if it does exist then delete it using the Kill statement prior to running the DoCmd.TransferSpreadsheet Method. Hopefully this will avoid someone some headaches trying to resolve a field error where there never was one to begin with!!!

I have an access table that has about 255 columns. Several fields need to be adjusted to a Yes/No instead of its current setting of text. When I try to change it, I get a "Too many fields http://www.pcreview.co.uk/threads/too-many-fields-defined-issue.3953667/ defined" message that pops up. Followed by "Errors were encountered during the save operation. Data types were not changed. Properties were not updated." What is the best way to resolve this? Thank you in advance. forest8, Jan 15, 2010 #1 Advertisements John W.

Then you have a Really Badly too many Designed Table. 30 columns is a very wide table. 60 columns is a *huge* table. >Several fields need to be adjusted to a Yes/No instead of its current >setting of text. Let me guess... a survey with one field per question? Have you seen Duane Hookum's "At Your Survey" design? It solves this problem. We may have discussed this earlier, I don't recall. >When I try to change it, I get a "Too many fields defined" too many fields message that pops >up. > >Followed by "Errors were encountered during the save operation.

When you change a field definition it adds a field with the new datatype, and copies the data from the existing field... eating up one of the 255 "slots". What you may need to do is change the definitions of one or two fields (few enough that you don't hit 255); Compact the database; change one or two more; etc. MUCH better... normalize your data so that your tables are tall and thin, not wide and flat. -- John W. Vinson [MVP] John W. Vinson, Jan 15, 2010 #2 Advertisements Jeff Boyce Guest Take a look at related posts in the tablesdbdesign newsgroup. You'll find that any table with more than around 30 columns is a likely candidate for further normalization. Although Access tables look a bit like spreadsheets, Access is NOT a spreadsheet. The way you'd structure data in a spreadsheet will only lead to much more work from you and from Access, trying to come up with workarounds for feeding it 'sheet data. Access' features and functions are optimized for well-normalized data.
