Hi Di,
SYMPTOMS
When you save a table after you add a new field or change the properties of
an existing field, you receive the message "Too many fields defined,"
followed by the message "Errors were encountered during save. Data types
were not changed." You receive these messages even though you have 255 or
fewer fields defined in the table.
NOTE: You also receive this message if you add or modify fields in a report
that is based on a table that has too many fields.
NOTE: This error message generates the Microsoft Jet Database Engine 3.0
Reserved Error number 3190.
This article assumes that you are familiar with Visual Basic for
Applications and with creating Microsoft Access applications using the
programming tools provided with Microsoft Access. For more information
about Visual Basic for Applications, please refer to your version of the
"Building Applications with Microsoft Access" manual.
NOTE: Visual Basic for Applications is called Access Basic in Microsoft
Access versions 1.x and 2.0. For more information about Access Basic,
please refer to the "Introduction to Programming" manual in Microsoft
Access version 1.x or the "Building Applications" manual in Microsoft
Access version 2.0
CAUSE
The internal column count that Microsoft Access uses to track the number of
fields in the table has reached 255, even though you may have fewer than
255 fields in the table. This can happen because Microsoft Access does not
change the internal column count when you delete a field. Microsoft Access
also creates a new field (increasing the internal column count by 1) for
every field whose properties you modify.
RESOLUTION
To free the internal column count for deleted fields or for fields whose
properties you modify, do one of the following:
In Microsoft Access 7.0 or 97, click Save As/Export on the File menu and
save the table under a different name. Then, delete the original table and
rename to new table to the original table name.
WARNING: Clicking Save As on the File menu in version 1.x or 2.0 copies
only the structure of a table, not the records. Do not delete the original
table until you use an append query to populate the new table.
In Microsoft Access 1.x or 2.0, click Save As on the File menu and save the
table under a different name. Populate the new table with data from the
original table. Then, delete the original table and rename to new table to
the original table name.
You can also free the internal column count by compacting the database.
