VB/MySQL Problem with fieldsize

I have written a program in VB which connects to a MySQL via MyODBC/ADO. My problem is that the textfields are limited to the szie of the longest entity within the recordset.

if the recordset has the following 2 dataentries...

field: id, text
1, abc
2, abcde

...then rec("text")= definedsize is 5

if the recordset has only dataentry 1 then rec("text") definedsize is 3???? In the MySQL Database (3.23.37) I have set text to VARCHAR(255).

Can anybody help me with this problem?

Thanks,
Chris

Hmmmm,
Sounds much like a MyODBC bug to me. Hurl an email to the MySQL guys and see what they have to say about it. There might be a patch for it.

...I found the bug. I have not set the options of the ODBC driver properly. If you create a connection without any options then ADO allows as maximum entry size of a field the size of the longest entry in that field in the record set - not the size spezified in MySQL.

With the right options everything is back to "normal".
