Quick Fixes:

What is Too Many Field Defined in Access?

Too Many Fields Defined Error is a clear sign that your Access table is either crossing its allotted field size limit or something went wrong in the Access field properties.

MS Access keeps counting the total number of fields added to the database table. Every single table of Access has a limit of 255 fields. Every time you make changes in the field property, this will increase the column count to 1. On the other hand, when you delete any field this column count won’t decrease and the field count remains as it is. Thus, it’s quite apparent to encounter 3190 error in such a situation

However, this error generally arises due to the following reasons:

  • Exceeding the maximum field limit
  • Excessive use of the calculated fields
  • Importing or linking the external data
  • Cross-tab queries or PivotTables.

How to Fix Too Many Fields Defined Access Error (3190)?

Carry out the following methods to fix the 3190 error in Access.

Way 1: Compact & Repair Your Database

To remove the deleted field counting from the internal column count compact the database. For this, you can take the help of the Compact and Repair inbuilt utility tool.

Follow the steps to compact your database using the Compact and Repair tool:

1: Firstly you need to open up your MS Access program.

2: After that make a hit on the Database Tools tab.

Way 2: Create A Fresh Copy Of Access Table

The second easiest way to fix Access too many fields defined error is by creating a new copy of the same Access table having the issue.

Note: Before performing this step, make a complete list of all the relationships contained in that table.

  • First, choose the table having the issue.
  • Go to the File menu, tap the Save As
  • In the opened Save AS window assign any new name to your table and click OK.

  • Now choose the table which you error showing table and delete.
  • After that rename your newly created table with the same name as the original one.
  • Setup all the relationships as it is previously contained in your deleted table.

Way 3: Pass-Through Query to Fix Too Many Fields Defined Access

As we have already discussed Access has a limit of 255 columns or fields for each table. So if you try to link with some other external link having more than 255 columns.  In that case, Access will only consider 255 columns starting from the first.

All I want to say is, with the linked table it’s not possible to choose any specific field or columns.

So, in order to retrieve the 256th column but drop out the 1st one then use the pass-through query:

  • Firstly, open your Access database.
  • Make a new Query within the Design View.
  • Close the opened dialog box of Show Table.
  • In the query type, you have to choose the Pass-Through.


  • Make a right-click on the Query tab and tap on the SQL View.
  • In the opened Query pane put the SQL statement.

e.g: SELECT Col1, Col2, Col3 FROM Account

  • Hit the Run.
  • Now choose the ODBC driver data source from the dialog box of Select Data Source.

Way 4: Set Other Field Properties


All types of formats don’t work well with all variants of data types. So always set the data type first and then only set its format.

  • In the grid design table, choose the field first, for which you need to set the field properties.
  • You will see that Access will show the field’s property in the Field Properties.
  • According to the data type, field property is assigned.
  • Within the Field Properties pane, make settings that you want to apply for each of the field property.

  • Alternatively, just press the F6 button from your keyboard and select the property using the arrow key.

Note: Get more information about the data types and field properties that are available for each kind of data type.

  • To assign extra space for adding or modifying the property settings within the property box. Just press the SHIFT+F2 key from your keyboard as this will open the Zoom box.
  • To save all the changes you have made, don’t forget to press the CTRL+S button.

Way 5: Change A Field’s Data Type

You have the option to change several aspects of the field after making it.


You can also change these aspects of a field that you did not just create. However, if data already exists in the field some actions will not be available or may cause data loss.

  • From the table design grid, choose the field for which you need to apply the data type.
  • Now from the column of the data type, choose the data type from the drop-down list.
