Why is Varchar type defined as TWideMemoField?

Question

PostgreSQL

Actually, subject. There is a Clients table in which there are 5 fields of the varchar type without specifying the length, because it is not known in advance what length the values ​​will be. I am connected through the same ADO to basis, I pull out static fields - they are defined as TWideMemoField. And when you try to display such values ​​in a table, such a contraption is displayed.

Postgresql base. How to avoid or fix this? Thank you.

Answer 1

The absence of a length can make it clear to the dataset that the provided data is from BLOB fields. Therefore, try to set the length or add fields of the required type manually in the designer or before opening in runtime.
