please help me,thanks.

Hi,
2 thoughts I have:
a) if you use Unicode generally in your DB, shouldn't your columns also have double the size, i.e. varchar2(12) instead of varchar2(6) etc.? This may not be an issue with this "colltime" column in this case, but maybe a general idea.
b) have you tried to use "simple" parameter names like ":a, :b, :c" etc. instead of the actual column names?

Tobias

thanks,New build of UniDAC version 3.00.0.7 is available for download now.

HELP,THANKS

We have reproduced this problem. And now we are investigating it. As soon as we get any results we will let you know.

We have fixed this problem. This fix will be included in the next build of UniDAC.
