Query: Size mismatch for field 'name', expecting: 50 actual: 254

When I try to open a dataset (linked to TQuery - simple select from
FoxPro-table using ODBC) at run-time I get error message - subj. But in
design mode that dataset can be opened successfully and I can see that in a
grid. The field 'name' actually has length of 50 chars and this value is set
up correct for corresponding persistent field.
