ODAC: nvarchar column value is truncated

Question

I am using ODAC library version 8.6.12 to connect to oracle with Delphi 6, I have a nvarchar(32) column as you can see it has a maximum of 32 characters and lets say that I always use 32 character values, e.g. "123456789-123456789-123456789-12"

The issue appears some times on customers PC that the result will be truncated to 16 characters, so the next code will show me a message with 16 characters "123456789-123456":

var MyID: string;
begin 
  MyID:= OraQuery.Field[0].AsString;//value must be "123456789-123456789-123456789-12"
  // -->> MyID = "123456789-123456"  only 16 characters 

Why I am having this issue? Does that depends on the Oracle version?

This is strange because the code used to work on the old ODAC, only on new ODAC 8.6.12 on some computers it doesn't work -on my computer it works fine-!

Answer 1

We have already fixed the problem, the fix will be included to the next version of ODAC, that will be released in the beginning of the next month.
