    Formatting Question

    Hello,



    I have over 270,000 records in my database with 4 fields. And for each field I need to make sure they dont go over a certain number of characters for example field1 can't go over 20. Is there a way I can make sure that they don't go over that? When I go to design view and go to the Data Type of each field I change the filed size to 20, but if something is imported into that field that is over 20 characters long will I get a message saying it won't import? Or can I write a query to check the whole field to make sure that nothing is over 20 characters?

    Thanks

    If you limit the field size to 20 characters then the import will either error and not import the data or truncate the value - can't remember which. You can do a test and find out what happens.

    A query can have an expression that calculates the length of values but that won't help with import.

    SELECT *, Len([Field1]) AS LenOfData FROM New;
